Under Committee Correspondence and Reports,Bob Orr reported on the Scada/Metering/Communications Subcommittee which was held in Fairbanks on November 14,Bob furnished a copy of the sub- committee minutes (see attached)and read the minutes into the record.Bob Day then gave a report on the Machines/Ratings Subcommittee meeting which was also held on November 14,1984. Bob noted that with the exception of Fairbanks Municipal Utilities System,the remaining utilities have forwarded their Machines/ Ratings data to Chairman John Spence.Bob furnished the Committee with minutes (see attached)from this subcommittee meeting. Marvin Riddle then gave a report on the Dispatch/Scheduling Subcommittee which also met on November 14,1984.Marvin noted that only Golden Valley Electric Association and Chugach Electric Association had furnished the subcommittee with written comments on the Anchorage -Fairbanks Intertie Operating Procedures Draft Manual.Marvin furnished the Committee with minutes (see November 15,1984 AFIOC Minutes Page 2 attached)from the subcommittee and read the minutes into the record.The Committee did not receive a report from the Reliability/Criteria Subcommittee as they had not met since the last regular operating committee meeting. Turning to the status on the Intertie Project itself,Bob Orr noted that the Gold Hill Substation is tentatively scheduled to be transferred to the new transformer at the end of November.Mike Yerkes reported that the transmission line itself is nearly complete and that Alaska Power Authority expected to be conducting tests on the entire Intertie by mid January to satisfy the contractual requirements with the various contractors.Mike also noted that the target date for Commercial Operation is expected to be early March 1985.Regarding the Draft Alaska Intertie Agreement,Mike noted that he has the current draft under review now that the Power Authority has received the latest changes from the Intertie Agreement discussions which were held in Anchorage in October,1984.Bob Orr asked Mike about the Intertie Operating Budget and what specifically would the APA be requiring and Mike indicated that APA would be working with the utilities to put a budget in place in the next 60 days. There were no visitors present at today's meeting;however,Mr. Harry Beck and Mr.John Aspnes of the University of Alaska- Fairbanks were present to provide a presentation under the New Business portion of the meeting. Having no Old Business to conduct,Bob Orr motioned for the Operating Committee to recess to a work session.John Marshall seconded the motion.The motion was approved unanimously.The Operating Committee then recessed into work session at 10:40 A.M. The Committee then turned it's discussion to the matter of the University of Alaska-Fairbanks Dynamic Stability Study and Bob Orr read from page 3 of the October 11,1984 Intertie Operating Committee minutes regarding the reason Dr.Aspnes and Mr.Beck were requested to make an appearance at today's meeting.Bob Orr then introduced Dr.John Aspnes and Mr.Aspnes furnished the Operating Committee with a revision (No.1)to the April 1984 University of Alaska proposal to perform a Dynamic Stability Study on the Anchorage-Fairbanks Intertie.The purpose of the revised proposal was to take into account a CEA request and an Operating Committee concurrence that the scope of work in the April 1984 proposal and the total funding be reduced accordingly.After a brief discussion from Dr.Aspnes,he then took questions from the Operating Committee.Bob Day asked that access to the UAF com- puter model program be limited to participants providing funding for the study.Dr.Aspnes read to the Operating Committee a letter from Mr.Jim Derky,UAF Computer Systems Manager regarding availability and access.The Operating Committee group felt it November 15,1984 AFIOC Minutes Page 3 was important to maintain control of the model and data base set up by the University.Bob Orr then asked Dr.Aspnes to point out the major changes in the revised proposal which was furnished at today's meeting and Dr.Aspnes responded as follows: 1.The University of Alaska-Fairbanks has deleted a future voltage model. 2.They have revised the number of case studies to be completed. 3.The proposal is more specific regarding what will take place. 4.The University of Alaska-Fairbanks will make fewer code programing code changes in the "745"program they are utilizing. The discussion then turned to SCADA/Metering/Communications and Bob Orr noted that the sign convention recommendation of the SCADA/ Metering/Communications Subcommittee which met on November 14, 1984 is intended to replace the sign convention system adopted by the full Operating Committee at a previous meeting.A question was raised as to whether future participants would be required to pursue computer systems with "DEC"hardware system and it was the general concensus on the group that this was true;however,a par- ticipant could possibly utilize a different type of computer system realizing that interfacing would be much more difficult. The Operating Committee then turned it's discussion to the Southern Control of the Intertie Project and it was brought out in the discussion that there was a need to provide more information and possibly remote control capability on the APA Eklutna Project. Mike Massin noted that ML&P would approach APA Eklutna about the problem and would bring more details back to the Operating Committee regarding what the intent is with APA Eklutna and the improvements they are making at the Eklutna power plant. The Operating Committee adjourned at 11:40 A.M.for lunch and reconvened again at 1:30 P.M. A discussion then began on the work of the Machines/Ratings Subcommittee and it was noted that the subcommittee is ready to begin assembling the data furnished by the participating utilties. It was again pointed out that the subcommittee was still waiting for FMUS to furnish machine data for their system.The Committee also discussed what other tasks the Machines/Ratings Subcommittee should pursue.It was noted that they did not need to pursue outage reporting. Turning to the Dispatch/Scheduling Subcommittee work,the Operating Committee discussed the comments from the two utilities,(GVEA and CEA),on the Anchorage-Fairbanks Intertie Operating Procedures Draft Manual and noted that Municipal Light &Power's comments,which are still due,should be forwarded directly to the Alaska Power Authority.It was noted that now-that Municipal Light November 15,1984 AFIOC Minutes Page 4 &Power will be the Southern Operator for the Intertie,that it is important to have this Operating Committee pursue any changes in operating procedures that might be required as a result of the change in the southern intertie operator.Bob Day proposed that the Northern and Southern Operators use consistent formating in thir data processing and scheduling procedures. The Operating Committee briefly discussed the work of the Reliability/Criteria Subcommittee and noted that this subcommittee had not met during the past month.The Operating Committee then discussed,at length,the need for the various subcommittees to be more agresSive in their respective work areas and the there be better subcommittee participation on the part of the respective subcommittee participant members.Several suggestions were made on how to improve subcommittee participation and in general they were already being pursued.It was also suggested by Chairman Orr that it might be helpful if the participant representative on the Intertie Operating Committee would take a copy of the minutes which are sent out and use a highlighter to remind the various subcommit- tee participants within the participant's organization of up-and- coming subcommittee activities. The Operating Committee then returned to full session at 3:00 P.M. Turning to formal Operating Committee Actions/Recommendations, John Marshall motioned that the Operating Committee through the Operating Committee secretary send a recommendation to each of the participating utility General Managers that the Operating Committee supports the revision No.1 proposal from the University of Alaska-Fairbanks regarding the Dynamic Stability Study which waS originally proposed in April 1984.(Attached is a copy of this revision No.1).Bob Orr seconded the motion.The members unanimously approved the motion. Mike Massin then motioned for Mr.Harry Beck from the University of Alaska-Fairbanks be placed on the Reliability/Criteria Subcommittee as a non-voting associate participant.Mike Yerkes seconded the motion.The members unanimously approved the motion. Bob Orr then motioned for the Operating Committee to accept the SCADA/Metering/Communications Subcommittee recommendation to revise the "sign conventions"which were adopted by the subcommit- tee at the November 14,1984 meeting.Mike Yerkes seconded the motion.The member unanimously approved the.motion. Mike Yerkes then motioned for Municipal Light &Power to complete their review of the Anchorage-Fairbanks Intertie Operating Procedures Draft Manual and that they furnish their comments directly to Mike Yerkes at the Alaska Power Authority.Mike then>further motioned that the Operating Committee direct the Dispatch/ November AFIOC Minutes Page 5 Scheduling Subcommittee and the Reliability/Criteria subcommittee to schedule a joint meeting to discuss the Anchorage-Fairbanks Intertie Operating Procedures Draft Manual and that they discuss | the comments submitted by all of the participant utilities.Bob Orr seconded the motion.The motion was approved unanimously by /the Committee. Turning to Subcommittee Assignments,Chairman Orr then directed THE DISPATCH/SCHEDULING SUBCOMMITTEE AND THE RELIABILITY/CRITERIA SUBCOMMITTEE TO MEET JOINTLY AT THE CEA ENGINEERING CONFERENCE ROOM ON DECEMBER 12,1984 AT 9:00 A.M.THIS JOINT SUBCOMMITTEE IS ALSO TO LOOK AT FORMS,DISPLAYS AND PROCEDURES FOR ENERGY TRANSFERS ON THE INTERTIE.

Bob Orr then motioned for the meeting agenda to be modified to include a presentation by Gilbert-Commonwealth regarding S.V.S. Start-up and Intertie Relay Settings.Mike Yerkes seconded the motion.The motion was approved unanimously. Under Committee Correspondence and Reports,Bob Orr reported on the joint meeting held between the SCADA/Metering/Communications Subcommittee and the Dispatch/Scheduling Subcommittee which occurred at ML&P on October 3,1984.Bob provided written minutes from this joint meeting.(see attached).Bob read the minutes into the Operating Committee record.Hank Nikkels gave a brief report on the October 4,1984 Machines/Ratings Subcommittee meeting.He noted that only himself and Mr.John Spence from CEA attended the meeting.Hank reported that the Subcommittee was still awaiting data submittals from Fairbanks Municipal Utilities System.No written minutes were furnished for this Machines/ Ratings Subcommittee meeting.Sam Matthews then reported on the October 10,1984 Reliability/Criteria Subcommittee which was held at ML&P.He reported that the Subcommittee had reviewed the cri- teria for the study which the Subcommittee was overseeing.Sam furnished minutes,(see attached),from the previous Reliability/ Criteria Subcommittee meeting which occurred on August 22,1984. He noted that minutes were also taken for the October 10,1984 meeting but were not yet typed and would be furnished to the Operating Committee secretary after today's meeting so they couldObeincludedintheminutesdistribution.It was noted,again,that the Dispatch/Scheduling Subcommittee had met jointly with theSCADA/Metering/Communications Subcommittee on October 3,1984 and that their activity was reported in the minutes from the joint meeting. AFIOC Minutes October 11,1984 Page 2 Mike Yerkes then gave a status update on the intertie project itself,and reported that APA was still looking at a December 15, 1984 date for total intertie start-up.Mike also reported on the Intertie Start-up Committee meeting held on October 4,1984.He indicated that no date had yet been set up for the next Intertie Start-up Committee meeting.Mike briefly discussed the Alaska Power Authority R.F.P.which was sent to Chugach Electric Association and Municipal Light &Power requesting a proposal to Operate the south half of the Intertie.Ron Krishana,from Morrison-Knudsen,then gave a brief report on the line section to be built from Teeland to Hollywood. At the conclusion of the Intertie Status Report by the Alaska Power Adminstration,Bob Orr from Golden Valley,noted,for the record,that Golden Valley Association was quite concerned about the time committment GVEA would be required to make for the Intertie Start-up.The concern centered around the time committ- ment required for Relay/Substation technicians at the various intertie substation sites.Bob did indicate,however,that the initial coordination meeting held with Gilbert-Commonwealth prior to the relay testing for the Gold Hill Substation was very help- ful.Mike Yerkes noted that Gilbert-Commonwealth is working on a schedule for the vaious utilities to allow them to plan for their Manpower committments.Bob Orr also expressed concern about the tie line start-up occurring during the December/January time period which coincides with utilities winter peaks.Mike Massin, from Municipal Light &Power,also expressed concern that the rapid push for intertie check-out completion and energization not result in situations where the line be subjected to frequent trips which could result in unfavorable publicity to the utilities. Mike also noted that Municipal Light &Power would be doing testing on its new turbine 8 and would not want to see start-up testing on the intertie compound any bad publicity which might occur as a result of turbine start-up testing. Under Committee Correspondence,Chairman Orr noted that the Alaska Power Authority had sent a letter to the Reliability/Criteria Subcommittee Chairman,Mr.Sam Matthews,regarding a summary of additional studies required to verify action of system reserves and automatic load shedding for the intertie.(see attached). Bob also read a letter from the Alaska Power Authority to Chugach Electric Association General Manager,Bob Martin,regarding the APA R.F.P.for control on the southern half of the intertie.It was noted that this same letter had also been sent to Municipal Light &Power. There were no visitors present at the meeting nor were there any requests for appearances. Having no business to conduct,the Operating Committee recessed to a work session at 11:00 A.M. .AFIOC Minutes October 11,1984 Page 3 The Committee then turned its discussion to the matter of the University of Alaska/Fairbanks Dynamic Stability Study,which has had difficulties getting a start due to utility concerns about the scope of the work the University was going to perform versus the scope of the work on other studies being conducted by consultants for the Alaska Power Authority,and after a lengthy discussion agreed that the Operating Committee Chairman,Mr.Orr,should con- tact Dr.Aspnes to discuss the following areas: A.Request the University Alaska/Fairbanks to revise the scope of work in their Dynamic Stability Study proposal to reflect the data gathering work already completed by Gilbert-Commonwealth. B.Ask Dr.Aspnes to attend the next Operating Committee meeting which will be held in Fairbanks and to give a presentation on the revised UAF Dynamic Stability Study proposal. C.Recommend to Dr.Aspnes that UAF re-contact the utility mana- gers regarding the funding required for the study in light of the CEA letter which proposed a reduced funding amount. The Operating Committee then turned their discussion to the Intertie S.V.S.operation and related intertie relaying settings and Chairman Orr introduced Mr.Irwin Hasenwinkle from Gilbert- Commonwealth who then furnished the Operating Committe members with an Operating Procedures Manual.Bob Orr then suggested that the Dispach/Scheduling Subcommittee should review this Operating Procedures Manual and recommend any changes to the next full Operating Committee which meets in Fairbanks.It was then decided that this matter would be discussed later in the meeting during formal recommendations and subcommittee assignments. The Operating Committee adjouned for lunch at 11:40 A.M.and reconvened again at 1:15 P.M. The discussion on the S.V.S.system and relaying settings pre- sented by Mr.Hasenwinkle continued until approximately 3:00 P.M, Turning to discussions on the SCADA/Metering/Communications Subcommittee,Ray Duncan indicated that CEA felt that sign con- ventions as adopted by the full Operating Committee still needed some review.After a short discussion,the concensus of the Operating Committee,was that additional review might be required in this matter.Mike Massin suggested that the SCADA/Metering/ Communications Subcommittee have a second look into this at their next meeting. Turning to the work of the Machines/Ratings Subcommittee,the Operating Committee discussed at length the need for this Subcom- mittee to pursue their work more vigorously, AFIOC Minutes October 1l,1984 Page 4 As discussed earlier in the meeting,it was felt that the Dispatch/ Scheduling Subcommittee should direct their efforts to reviewing the Operating Procedures Manual furnished to the full Operating Committee by Mr.Hasenwinkle from Gilbert-Commonwealth Associates. It was also felt that this Subcommittee should begin looking at N.E.R.C.Guide No.10. Regarding the work of the Reliability/Criteria Subcommittee,Mike Massin noted that the Reliability/Criteria Subcommittee had been directed at the previous full Operating Committee meeting to recommend to the Operating Committee any other studies which they felt would be necessary to insure proper operation of the inter- tie.Bob Orr indicated that there would be a need for a study to identify loss determination in conjunction with operating the intertie and scheduling power flows.The Operating Committee mem- bers were in agreement in this matter. Under Formal Operating Committee Actions/Recommendations,Sam Matthews motioned for the full Operating Committee to adopt the Minimum Intertie Operating Requirements as recommended by the SCADA/Metering/Communications Dispatch/Scheduling joint meeting which was held on October 3,1984.These recommendations are con- tained in the meeting minutes for this joint subcommittee meeting. John Marshall seconded the motion and the motion was carried una- nimously by the members present.(Mike Yerkes,from the Alaska Power Authority was excused from the meeting prior to the start of formal recommendations.) Bob Orr then motioned for each utility to review the data as con- tained in the Alaska Railbelt Interconnected Electric System Data Book (two volumes)which was previously furnished to participants in the Reliability/Criteria Subcommittee and that each utility have their written response to the data sent to Dr.Prabhakara of Gilbert-Commonwealth no later than October 26,1984.Mike Massin seconded the motion.The motion was carried unanimously by the members present. Bob Orr then motioned for each utility to review the Anchorage Fairbanks Intertie Operating Procedures draft manual as furnished by Mr.Hasenwinkle at today's meeting and that each utility pro- vide their written responses to their respective Dispatch/SchedulingSubcommitteerepresentativeforfinalsubcommitteereviewpriorto November 11,1984.John Marshall seconded the motion,The motion was carried unanimously by the members present. Noting that the Machines/Ratings Subcommittee still needs data information from Fairbanks Municipal Utilities System to complete the Machines/Ratings handbook,Bob Orr then motioned that Fairbanks Municipal Utilities System be requested to furnish thisinformationtotheMachines/Ratings Subcommittee chairman by the 24th of October 1984.This time frame is necessary for Chairman Spence to provide a reponse to Dr.Prabhakara by October 26,1984.Sam Matthews seconded the motion.The members present unanimously approved the motion. AFIOC Minutes October 1l,1984 Page 5 Turning to Subcommitte Assignments,Bob Orr motioned that the Dispatch/Scheduling Subcommittee be directed to review the Intertie Operating Procedures draft manual,taking into account their respective utility written comments and provide a written recommendation to the full Operating Committee at its next meeting to be held in Fairbanks.Additionally,the Dispatch/Scheduling Subcommittee is directed to review N.E.R.C.Guide No.10,N.E.R.C. Performance Criteria,N.E.R.C.Minimum Criteria for Operating Reliability and make written recommendations to the full Operating Committee.The motion was seconded by Sam Matthews.The motion was unanimously approved by the members present. THE DISPATCH/SCHEDULING SUBCOMMITTEE WILL HOLD ITS NEXT MEETING ON NOVEMBER 13,1984 AT 9:00 A.M.AT THE ENGINEERING CONFERENCE ROOM OF CHUGACH ELECTRIC ASSOCIATION. Bob Orr them motioned for the SCADA/Metering/Communications Subcommittee to review all N.E.R.C.references in relationship to "sign conventions".The Subcommittee is also directed to review the Alaska Power Authority's method of meeting interim operational requirements for the entire intertie project.John Marshall seconded the motion.The members unanimously approved the motion.

A joint subcommittee meeting was held in Anchorage at Anchorage Municipal Light &Power.Following are those who attended the meeting: Linda Stewart -CEA Vance Cordell -CEA Robert Orr -GVEA Marvin Riddle -GVEA Afzal H.Khan -APA Mike Yerkes APA Robert Day MLEP Bob Orr,chairman,called the meeting to order.Mike Yerkes,after previous©discussions with ML&P and CEA,asked both utilities to expand their SCADAproposals.The technical quidelines used by APA were Standards developedbytheOperatingCommitteeandSubcommittees. Both cases (proposals)appear to be functional but more details will be required to evaluate these.There will have to be some additional questions answered. The CEA proposal to provide SCADA control (southern end)consisted of four different proposals.These are explained further in detailed proposal. (One line diagrams attached.) There seems to be a question that the BBC DEC 11/70 would not be compatible/ accept DECNET in its present configuration.This concern is expressed by CEA and their consultant. The proposal labeled Appendix E from CEA is the proposal APA is most actively evaluating as it appears to be the closest to the RFP from APA. AMLEP's committment to operation on the southern portion of the intertie needs to be better defined.They need to describe in more detail,an operating plan for APA to evaluate their SCADA proposal.The AML&P proposal was also being evaluated by APA and more detail per attachment titled "Questions to Proposers on APA's RFP to SCADA Systems"is included. Time frames for implementation of CEA,AML&P SCADA proposals: AML&EP -RTU45s available Nov.1984 (Teeland,Doublas,CEA Tie) -Master Station available Jan.1985 11/44 DEC -Data Link,Jan.1985 CEA -BEC Proposal,16-20 weeks from agreement -D&E Proposals,7 months -on line load flows within 12 months -Interim System Proposals,(see attached)pi gdLleMarvinastated he felt minimum requirements to operate the intertie were: '1.Instantaneous var,watt flows in-out. 2.WHR and VARH metering for billing. 3.Healy,Gold Hill,Teeland and Douglas are required substation.This is because of the metering and indication and control of SVS at both endsofintertieaswellascircuitbreakers. id 4.Bob Orr stated determining power mix from southern utilities would be necessary for billing and accounting purposes. 5.Also intertie points at CEA-AMLP,GVEA-FMUS,this to include watt-VAR flows. 6.Voice communications North to South Subcommittee discussed the above minimum requirements for operation of the intertie. After discussion,the subcommittee voted unanimously to recommend these minimums for operation to the Operating Committee. Contingency operation (interim)for two southern substations -GVEA's Bob Orr and Marvin Riddle described a method by which interim operations could be addressed.That is;instal]RTU at Teeland and connect to GVEA temporarily to operate. Bubble Memory Conversion -Transferring bubble memory to mag tape is being worked on by J.Hall,MEA.Software is presently in design,three formats. Doesn't have firm date yet but still working on it.

Bob Orr motioned that the minutes be adopted as written.Ray Duncan seconded the motion.The motion was approved unanimously. (Secretary Note:The July 12th meeting was held in Fairbanks,not Anchorage.) Mike Massin then motioned for the meeting agenda to be modified to delete the General Electric SVS Presentation.Ray Duncan seconded the motion.The motion was approved unanimously. Under Committee Correspondence and Reports,Bob Orr reported on the SCADA/Metering/Communications Subcommittee meeting which was held at CEA on Wednesday,August 22,1984.Bob reported that the Subcommittee had agreed to and established sign conventions for intertie metering.He also noted that the Subcommittee had discussed Intertie synchronizing sign conventions.Bob furnished the Operating Committee with a set of minutes from the SCADA/Metering/Communications Subcommittee meeting (see attached Minutes). Mike Massin noted that the Machines/Ratings Subcommittee did not hold a meeting during the time interval since the last Operating Committee meeting.Bob Orr read a letter which Machines/Ratings Subcommittee Chairman John Spence had sent to the Machines/Ratings Subcommittee members on July 10,1984.(See attached copy of letter). Tom Martin gave a brief report on the Reliability/Criteria Subcommittee which met at Municipal Light &Power on Wednesday, August 22,1984.Tom noted that the Subcommittee had discussed loadshedding on the north half of the intertie and how it would ?$ AFIOC Minutes August 23,1984 Page 2 be impacted by the inertia of the entire intertie interconnected system.He also noted that the Subcommittee had identified some stability cases they wanted to have run.(Note:Sam Matthews took minutes of meeting,however,they are not attached as a handout).It was also noted that Dr.Prabhakara handed out to this Subcommittee a two volume collection called "The Alaska Railbelt Interconnected System Data Book",The Subcommittee members were asked to review and comment on their respective utilities data as published in the two volume data book.Dr.Prabhakara also fur- nished the Reliability/Criteria Subcommittee with additional discussion topics. Marvin Riddle reported on the Dispatch/Scheduling Subcommittee meeting which took place at CEA on Wednesday,August 22,1984. Marvin reported that the Subcommittee had discussed scheduling formats.He also noted that the Subcommittee had discussed screen format displays.He also indicated that he felt the formatting discussions were developing very well.(No minutes were taken at this meeting). Mike Yerkes,from the Alaska Power Authority,was then asked to provide the Operating Committee with a brief status report on the Anchorage-Fairbanks Intertie construction.Mike began by noting that he had asked Duane Chaffee of Morrison-Knudsen (Intertie Construction Manager)to come to today's Intertie meeting to report on intertie construction scheduling.Mike noted that Duane would be arriving shortly for the meeting.He also reminded the Operating Committee members who are also members of the Intertie Start-up Committee,that the Start-up Committee would meet at Municipal Light &Power immediately after the Operating Committee adjourned.Mike reported that the south half of the intertie tie line construction is nearly ready for final accep- tance.Mike then indicated that the Alaska Power Authority is quite concerned about CEA's committment to SCADA and to dispatching the southern half of the intertie.He noted that the Alaska Power Authority intends to approach ML&P and ask that ML&P consider operating the southern end of the tie line.Mike also indicated,however,that the Alaska Power Authority will also pur- sue the problem of SCADA installation reimbursement and operation of the south half of the intertie with the upper management of CEA. Bob Orr then read a letter from Mike Kelly,General Manager of Golden Valley Association,which was addressed to Robert Day (Acting Secretary of the Operating Committee)regarding a letter Bob Day had sent to the General Managers of the utilities con- cerning the intertie budgeting process.(See attached letter). There was one visitor in attendance at today's meeting.Mr.Harry Beck,from the University of Alaska,Fairbanks,Electrical Engineering Department,gave a brief report to the OperatingCommitteeontheworkUAFisdoingontheDynamicStability Study AFIOC Minues Aughst 23,1984 Page 3 requested by the four intertie Utilities.He noted that the UAF/EE Department had secured approval from the Department respon- sible for the University computer to allow the utilities to tie into the UAF program which contains the intertie model.He noted that UAF is preparing a fee amount schedule to allow for the storage of data.He also noted that control of the program will be through the UAF-EE Department. Turning to Old Business,a lengthy discussion took place on the scope of the work the UAF Dynamic Stability Study would follow. Tom Martin expressed concern on the part of CEA that the scope of work for the Dynamic Stability Study be detailed enough to clearly explain the benefit that CEA would receive in exchange for the $20,000 contribution it was being asked to contribute.Tom also expressed concern that this work may be a duplicate of data gathering done by G/C/A.The general concensus of the Operating Committee excluding CEA was that the work proposed by the University of Alaska Fairbanks was reasonably well documented in the proposal furnished to the Operating Committee at the Operating Committee meeting held in Fairbanks on March 21,1984.The discussion became very heated before it came to an end. At approximately 11:00 A.M.,Duane Chaffee from Morrison--Knudsen arrived and was introduced by Mike Yerkes.Duane then proceeded to furnish the Operating Committee members with the following information:The south half of the intertie line segment is sche- duled for final acceptance approximately September 6,1984.The north half of the intertie line segment is scheduled for comple- tion by late October.The Teeland to Hollywood line segment is scheduled for completion by early October.The Douglas Substation is scheduled to be completed and ready for functional testing by approximately October 15,1984.The Gold Hill Subdivision is scheduled and ready for functional testing by approximately October 20,1984.The Teeland Substation is scheduled for comple- tion and ready for functional testing approximately November 1, 1984.The Healy Substation is scheduled for completion and func- tional testing by approximately November 20,1984.The Cantwell Substation is scheduled for completion and functional testing approximately mid November,1984.Duane noted that the SVS equip- ment is all in Alaska except for two shunt reactors which were damaged during shipping.Bob Orr asked Mr.Chaffee about quality control on the project.Chaffee indicated that quality control was good in general.Duane indicated that it looked like the tie line could be energized in mid-December if completion date come together.Larry Van Blarcum indicated that two to three weeks of testing per substation was not unreasonable. The Operating Committee recessed for lunch at 11:40 A.M.,and the meeting resumed again at 1:30 P.M. When the Committee meeting resumed,the Committee went into work session.No G.E.SVS presentation was made at today's meeting. ';s AFIOC Minutes August 23,1984 Page 4 The Committee began a discussion on SCADA/Metering/Communications and in particular regarding the conversion of bubble memory data to mag tape data.The Operating Committee members felt that the Subcommittee should look into this matter more closely.Bob Orr also indicated that he felt the SCADA/Metering/Communications group should look at minimum requirement for metering on a con- tingency basis. Turning to the work of the Machines/Ratings Subcommittee,it was the concensus of the Operating Committee members that this Subcommittee should be given specific assignments and that the Machines/Ratings Subcommittee should be given specific meeting schedules to insure that the Subcommittee is more productive. Discussion then turned to the work of the Dispatch/Scheduling Subommittee and it was the feeling of the Operating Committee mem- bers that this Subcommittee should begin to look at alternative methods for communications for scheduling in the event of loss of microwave communications. No additional discussion took place in the area of Reliability/ Criteria. The Operating Committee took no formal actions at today's meeting. Turning to the up and coming work of the various Operating Committee Subcommittees,the Operating Committee then proceeded to make Subcommittee assignments. Bob Orr then motioned that the SCADA/Meterings/Communications and Dispatch/Scheduling Subcommittees hold a joint meeting at their next gathering.He further motioned that both Subcommittees work on contingency plans for minimum SCADA operations and that the SCADA/Metering/Communications Subcommittee be further directed to resolve the bubble memory gathering standards.(APA is also to have Gilbert-Commonwealth present to the joint Subcommittee meeting for discussion an interim SCADA plan for Start-up and Operation).Mike Massin seconded the motion.The motion was approved unanimously.THE JOINT MEETING OF THE SCADA/ METERING/COMMUNICATIONS AND DISPATCH/SCHEDULING SUBCOMMITTEES WILL TAKE PLACE AT 9:00 A.M.ON WEDNESDAY,OCTOBER 3,1984 AT THE ML&P CONFERENCE ROOM. Bob Orr then motioned that the Machines/Ratings Subcommittee be directed to complete the Machines/Ratings handbooks and that they further cross check the Generation (mechanical and electrical) data that the Reliability/Criteria Subcommittee is using for their studies.This data is included in the "Alaska Railbelt Interconnected Electric System Data Book"(2 volumes)which was furnished to the Reliability/Criteria Subcommittee on August 22, 1984.Additionally,the motion requested that the Machines/Ratings é AFIOC Minutes August 23,1984 Page 5 Subcommittee Chairman (Mr.John Spence)be directed to send all Machines/Ratings handbook data gathered to date directly to Dr. Prabhakara prior to September 5,1984.Mike Yerkes seconded the motion.The motion was approved unanimously.THE MACHINES/RATINGS SUBCOMMITTEE IS SCHEDULED TO MEET AT 9:00 A.M.ON THURSDAY, OCTOBER 4,1984 AT THE MUNICIPAL LIGHT &POWER CONFERENCE ROOM. Mike Yerkes then motioned for the Reliability/Criteria Subcommittee to complete a plan and schedule required to finalize their review and conclusions in the assigned areas prior to the Start-up of the Intertie.He also motioned that the Subcommittee finalize a listing and criteria of additional studies necessary to complete their analysis of their areas of concern.The motion was seconded by Bob Orr.The motion was unanimously approved.THE RELIABILITY/CRITERIA SUBCOMMITTEE IS SCHEDULED TO MEET AT.1:30 P.M.ON WEDNESDAY,OCTOBER 3,1984 AT THE MUNICIPAL LIGHT AND POWER CONFERENCE ROOM. The Committee then set the agenda for the next monthly meeting. See attached.

Ray Duncan then reported on the July 11,1984 Dispatch/Scheduling Subcommittee meeting which took place in Fairbanks.Ray noted that the Subcommittee went to the Golden Valley Electric Association offices to look at the new GVEA Dispach Center.He noted that CEA will attempt to meet the formating of the GVEA Dispatch Center screen terminal display formats.(See attached display formats.)No minutes were furnished for this Subcommittee meeting. = Mike Yerkes then furnished a status update on the Anchorage/Fair- banks Intertie.He reported that the Alaska Power Authority and Chugach Electric Association had reached a tentative agreement on the Teeland Substation maintenance contract.He noted that Gilbert-Commonwealth is finalizing the protective relaying recom- mendations for the Intertie and they will go to the Intertie Reliability Subcommittee in the near future.He reported that Gilbert-Commonwealth is also preparing a draft Intertie Start-Up Manual for use by the Intertie Start-up Committee.He indicated that there will be a meeting during the week of July 16th for the Intertie Start-up Committee.Regarding the Start-up Committee representation,he reported that nearly all of the Utilities have now designated a representative.When asked about the status of the Utilities Draft Intertie Agreement,he reported that the Alaska Attorney General's office is still reviewing the document. Finally,Mike reported that APA is in the budget preparation pro- cess at this time and will be requesting that the Utilities involved in the Intertie furnish budget documentation support material. There were no visitor comments;however,Mr.Harry Beck from the University of Alaska-Fairbanks,Electrical Engineering Department, did sit in as a visitor at today's meeting. The Committee had no old business to conduct at this meeting. Turning to new business,the Committee then recessed into a worksession,The General Electric SVS presentation which had been on the agenda for several sessions,again did not take place. Turning to SCADA/Metering/Communications discussion,Bob Orr indi- cated that GVEA is still somewhat concerned about the GEM metering package.The group then turned their discussion towards powerflowconventionsandfeltastrongneedtostandardizepowerflowconvention.The group spent a considerable amount of time discussing this very important subject. July 12,1984 AFIOC Minutes Page 3 Turning to Dispatcher/Training,CEA again indicated they didn't feel they could support a second Dispatcher Training Workshop based on the results of the first workshop and backfeed from their employees that attended the session.Both ML&P and GVEA indicated they would support a second training workshop in the future. The Committee then turned its discussion towards the handouts fur- nished by Dr.Prabhakara and it was noted that the handouts were intended for the Utilities to review and comment.THE COMMENTS ON THE HANDOUTS FROM DR.PRABHAKARA ARE TO BE TURNED BACK IN TO GILBERT-COMMONWEALTH PRIOR TO AUGUST 1,1984. The Committee recessed for lunch at 12:10 P.M.and the meeting resumed again at 1:15 P.M. When the Committee meeting resumed,the discussion turned to the work of the Machines/Ratings Subcommittee and in particular the handouts furnished by Hank Nikkels regarding Component Cause Code Reporting. Turning to Dispatch/Scheduling,Ray Duncan indicated that he would like to have the Dispatch/Scheduling Subcommittee hold their next meeting at the new Chugach Electric Association Headquarters Building in Anchorage to allow the Subcommittee to observe the new CEA SCADA System display screen formats.The Committee then spent a short amount of time discussing the commonality and requirements for displays on the various Utilities SCADA and Dispatching systems. Although very little discussion took place regarding the work of the Reliability/Criteria Subcommittee,the Operating Committee did express a feeling that the Reliability/Criteria Subcommittee is off.to a good start and is on tract. Turning to the Operating Committee Budget,the concensus of the Operating Committee was that the budget previously prepared by the Operating Committee and forwarded to Mike Yerkes at the Alaska Power Authority was still a valid budget recommendation,fan nen . ae At 1:50 P.M.,the Committee left the work session and moved on to the formal action portion of the business meeting.At this point,Bob Orr made a formal motion that the SCADA/Metering/Communications Subcommittee work towards setting standards for metering conven- tions with respect to individual utilities and the relationship of in/out and plus/minus for watthour meters,var meters and var hourmeters.Additionally,the Subcommittee should address lead/lagrelationshiptoin/out on var/var hour meters,Finally,theSubcommitteeshouldaddresstheconventionforsynchroscopes.

Second item of business was the modification of the agenda which was to remove GE from Item 4B as General Electric will not be making the presentation today.Also deleted was the Machines/ Rating Subcommittee Meeting report as there was none available. Bob Orr moved to accept the agenda as changed.Mike Yerkes seconded and the agenda was approved unanimously. The SCADA/Metering Subcommittee report was given in combination by Bob Day and Dan Rice.The minutes of that meeting were submitted and are included as an attachment. There was a Reliability Subcommittee report by John Marshall.The minutes are forthcoming which will include a list of the studies. An Intertie Status report update was given by Mike Yerkes. Construction proceedings on schedule and the participants can expect a November/December completion date.Mike mentioned that we may need to be looking at a possible alternate plan for opera- tion of the Intertie without having the data link in place.As it appears the data link will not be ready at the time the construc- tion is complete. Revised 7/12/84 June 14,1984 AFIOC Minutes Page 2 APA wishes to get the Start-up Committee operational.There will be a letter coming out in the next few days to that effect. There was a general discussion of SCADA development and the imple- mentation of the SCADA control.There was a question from Bob Orr on the quality control of the Northern Contract because the contractors are proceeding so rapidly.Bob noted that they are building a good line which is well designed,but due to the fact that the contractor is moving so fast,he questions APA's ability to properly inspect the line and the construction practices.Mike Yerkes responded that they have quadrupled the staff for inspec-- tion on the north section.Yerkes is very satisfied with the inspection and staffing and considers it adequate. Bob Orr asked for any visitor comments and none were forthcoming at this time. The group then moved on to old business. There was a discussion on the letter from the secretary to the General Manager's which was outlined in the May 9,1984 minutes about budget and operating funds.Mike Yerkes discussed the Situation.He stated that the budget is approved and committed before funds are collected from the participant.The committee, as a group,then helped to author a letter that will be sent to the General Managers advising them of a possible problem with the revenue going to the general fund and the allocation method by the legislature.If the legislature happened to not approve the. budget or allocate proper funds,then the Intertie might be in a precarious position.Each manager will be advised to resolve this to his/her satisfaction.A copy of the letter will be attached. Under other old business,Mike Yerkes commented that he as APA's representative considers the important work:(1)the completion of the SCADA Subcommittee work,and (2)the Reliability Subcommittee work. John Marshall had some questions on relay settings.Dan Rice, from Gilbert-Commonwealth,will distribute the settings and work sheets,if available,and we will send these to the Reliability Subcommittee members. APA is making a committment to have an Engineer on board to work | with and to assist the Anchorage-Fairbanks Intertie Operating Committee;however,this may not occur for sixty to ninety days.| The SVS presentation was postponed to the afternoon,and at 10:50 A.M.,the group recessed:into work session. OoJune 14,1984 AFIOC Minutes Page 3 The first item of business into the work session was discussion of the SCADA/Metering/Communications Subcommittee.There was a question on the requirement for CEA to place an RTU at Healey. Bob Orr discussed and mentioned there may be some problems with the GEM metering package in that it does not do the things that he expected it to do.He will be advising the committee on this in the future,as his information was only preliminary at this time. Under Dispatcher/Training,there was a report on the dispatcher training from Ray Duncan.The classes recently occurred and are presently going on at the University of Alaska at Fairbanks.

Respectfully submitted,A MW 020 Robert Day -Acting Secretary Anchorage-Fairbanks Intertie Operating Committee RD/csn ANCHORAGE -FAIRBANKS INTERTIE RELIABILITY/CRITERIA SUBCOMMITTEE MEETING June 27,1984 The Intertie Reliability/Criteria Subcommittee meeting was called to order at 9 a.m.by Chairman Matthews.Others present were Jim Hall,MEA;Larry Colp, FMUS;Steve Haagenson,GVEA;and Larry Hembree,ML&P;Mike Yerkes,APA, arrived late;John Marshall,CEA,was absent. The first priority item of the Subcommittee as mandated by the full Committee is to investigate adequacy of reserves of each utility to see if they meet the contract requirements. It was noted that the prior subcommittee meeting was indexing and reviewing of prior engineering studies done for the Intertie.All system studies to date done by Gilbert Commonwealth and General Electric were to address specific technical or engineering problems.None have been done for strictly operational reasons.Gilbert/Commonwealth Item 3 is mostly complete except SVS not included. The Subcommittee goal is to utilize prior studies and information to the maximum extent possible.The task ahead is to define what we want the consultant to do in relation to the scenarios to be investigated,refinement of basic info.,etc. Reserve Investigation Consultant is to do the following: 1.Data collection and unification of prior studies and information. A.Get actual generation data rather than handbook. B.Publication of data collected for review. 2.Do Dynamic Stability Study of Operating Levels. A.Use loadings and proposed methods of meeting the reserve requirements for each utility.This would include spin,reserve load shed,(non-reserve load shed?),load levels,on-line generation dates,system configuration,etc. B.Configuration and status of Major System Improvements. C.Recommend scenarios to be investigated for review by Subcommittee. D.We want to be able to evaluate reserve adequacy.Arrive at optimum values for load shed sequence.

The next meeting is tentatively scheduled for August 8, 1984 in Anchorage. Respectfully submitted, Sam Matthews Anchorage 'Fairbanks Intertie Operating Committee May 9,1984 (At Anchorage) ATTENDANCE:John Marshall Chugach Electric Association Ray Duncan Chugach Electric Association James Hall Matanuska Electric Association Marvin Riddle Golden Valley Electric Association Keith Sworts Fairbanks Municipal Utilities System Sam Matthews Homer Electric Association Robert Orr Golden Valley Electric Association Dan Rice Gilbert-Commonwealth Bob Day Municipal Light &Power Mike Yerkes Alaska Power Authority The meeting was called to order by Chairman Bob Orr at 9:30 A.M. The first item of business was the adoption of the prior minutes of the April 18th meeting.Request was made for any comments or changes.John Marshall moved to accept the minutes as written, Keith Sworts seconded the motion,The motion was carried unani- mously. The second item of business was to approve a modification of the agenda.Ray Duncan suggested that Agenda Item 6B was to be deleted,that is a report from General Electric on the Static Var System.Keith Sworts so moved,Bob Orr seconded and it was unani- mously approved that that item be removed from the agenda. Secretary comment:General Electric was not ready to make such presentation,but plans were later made in the meeting to provide such a review on the next meeting of the Intertie Committee, The third item of business was that of the Committee Correspondence.The first subcommittee was the SCADA/Metering Subcommittee.Minutes on the Data Link were passed out and the next meeting is scheduled for May 24,1984,for this subcommittee. No activities have occurred for this group other than the minutes of their last working session meeting. Dan Rice presented a schedule of the Data Link activities which was distributed to the members and which is enclosed in the minu- tes. Next,a report from the Dispatch/Scheduling Subcommittee was given by Marvin Riddle.It was suggested that prior to February l, 1985,a complete maintenance schedule should be presented and 0AFIOC Minutes May 9,1984 Page 2 coordinated among all participants of the Intertie.Each suc- ceeding year after that,this activity should take place.The Subcommittee recommended the adoption of NERC 16 with no changes. The Chairman directed the Subcommittee to submit the NERC Guide in its final form.The Dispatch/Scheduling Subcommittee was also asked to establish its priorities.It presented its priorities as,1)discussion of reporting requirements,2)computation of reports and schedules.Jim Hall requested that MEA be included in the maintenance scheduling,especially that maintenance scheduling where maintenance on the line itself was being performed.Third priority was that the group work on a standard schedule for the SCADA systems.This schedule is not a time schedule,but a pre- sentation schedule so that the operators are looking at the same display of information.Priority number four was training and training courses.Some discussion was held over the Leighton and Kidd/PTI video training tapes.It appears that the group can be treated as a pool in which case it is $1,000 charge per each par- ticipant to cover the copyright.The two classes suggested,it appears,will cost around $32,000.Marvin Riddle requested a reply from the members of the group as to whether they will par- ticipate in this or not within one week.It was announced that the management overview at the University of Alaska would occurr at 1:30 P.M.,May 16,1984,Room 115 off the Duckering Building.A request was made as to how many people would attend,a head count was given,and approximately eight people will be attending. The next Subcommittee was that of Machines/Ratings.Chairman Orr officially received the document as sent by John Spence with a draft copy being sent'to the Committee members.(Attachment enclosed). The next Subcommittee to report was that of the Reserves/Load- shedding Subcommittee.Mike Yerkes made a formal request to establish a Systems Group Subcommittee to perform the indicated studies requested by the Reserves/Loadshedding Subcommittee, That concluded the reports from the various Subcommittees, Mike Yerkes then proceded to give an Intertie status update.He stated that the tentative Management Tour is set for the 22,23, and 24 of May.Questionaires are out and being filled in.Members are to contact Dave Eberley at APA if any additional information is required.Mike stated that every indication is there that the job is on task and he had an interesting discussion of the heli- copter construciton procedures.Mike Yerkes,again,recommended an establishment of a Start-Up Committee to handle the inspection, planning and considerations for start up.Bob Orr recommended that one Engineering type and one Operations type serve on this subcommittee, OAFIOC Minutes May 9,1984 Page 3 The subject was tabled for further consideration during the work session. Chairman Orr passed out two related items of correspondence from Mike Yerkes of the Alaska Power Authority referring to the budget submittal request.Mike requested that the Operating Committee review the budget prior to its conclusion. Letter No.2 presented written confermation of APA's receipt of the Operating Committee letter of March 23,1984.(See letter enclosed).° AS no visitors were present,no comments or information is forth- coming from them. There was no old business to be done. At 10:30 A.M.,Chairman Orr moved the group into work session. Marvin Riddle reminded everyone of the May 24,1984,9:00 A.M. meeting for the SCADA/Communications Subcommittee meeting. There was discussion on Dispatch/Scheduling.The two priorities were recording procedures and standard scheudules for Intertie to Operations.There was no discussion on NERC Operation Guide No.16. There was a discussion of Harstead Ebasco load data and the release of this information.The information submitted by John Spence was brought under discussion.Discussion insued about the three cur- ves and how they are used.It was noted that FMUS was not listed in the data sheet, There was some discussion on the drafts on the test reports and standards with the question centering around the last paragraph. There was strong discussion of NERC/GADDS versus IEEE defini- tions in use.Bob Orr noted that some of the definitions;i.e., generator,unit;are not present in the IEEE definitions as pre- sented.It was also noted that since many of the Operating Procedure and Guidelines are centered around NERC/GADDS,it would be very consistent to adopt the NERC/GADDS definitions. The minutes of the Reserves/Loadshedding Subcommittee were then reviewed;and a long discussion insued about the proposal from the University of Alaska and their proposal to do some tranisent ana- lysis studies,loadshedding studies and other stability type stu- dies.Some of the suggestions were to identify a subcommittee to do that function.It was asked that each member identify their AFIOC Minutes May 9,1984 Page 4 individuals which they wish to assign to that type of study.This would be called the Reliability/Criteria Subcommittee.The mem- bers from each utility should be a technical type,very familiar with the individuals utility and have the ability to coordinate these activities among the different utilities and the Intertie, Dan Rice proposed to compile the information and distribute it within a couple of weeks giving the new Subcommittee time to review and place the first meetin near the next Operating Committee Meeting with the additional constraint that General Electric and Gilbert-Common-wealth would be here to discuss the studies and any future need for studies, Under budget,there was a large discussion on the Intertie Agreement and whether or not the wording as proposed is adequate regards the budget and the right to contract for services as long as those services do not exceed the budget.Concerns were voiced about the budget process resting with the State,the APA will not control the total budget,but just a percentage of the par- ticipation.Further rewording of the agreement is being worked on. The Start-Up Subcommittee was discussed and the participants wish to be involved,but the committee us unsure as what degree they wish to be involved.The participants need to be involved such that they are comfortable with the line and its construction, Operation and start-up procedures,but they are not in a position to dictate those procedures.It was generally felt through the discussion that APA's Project Manager is the one that needs to coordinate with the utilities.One possibility discussed was that the Subcommittee would consist of the three directly affected uti- lities. At 12:30 P.M.,Chairman Orr returned the Committee to full session and called the meeting back to order. The first item of business was concerning Dispatch/Scheduling. Marvin Riddle moved that the Dispatch/Schedule's next priorities be detailed reporting and standard schedules and to rewrite NERC Guide No.16 and submit it for approval.Keith Sworts seconded, the motion carried unanimously. The second item of business,Bob Day motioned that each utility issue a letter of nonobjection releasing the Harstead Ebasco load data to the various members of the Intertie group.These letters are to be consolated by the Operating Committee and forwarded to Basco as a unit.Keith Sworts seconded it,the motion carried unanimously. AFIOC Minutes May 9,1984 ste yyPage5ue The third item of'business,Bob Orr motioned to approve the draft outline dated March,1984 as submitted by John Spence.He also motioned to direct the Subcommittee to continue gathering data for the handbook and to provide a consistent set of definitions spe-cifically considering the NERC/GADDS.The motion also directed the Subcommitteeto review the test procedures utilized by thememberutilities.Sam Matthews seconded,there was no further discussion,the motion carried unanimously. The fourth item of.business was the Reliability/Criteria Subcommittee.Bob” Orr made a motion to activate the Reliability/ Criteria Subcommittee consisting of the following members:MikeYerkesfromtheAlaskaPowerAuthority,Larry Colp from Fairbanks Municipal Utilities System,Jim Hall from Matanuska Electric Association,John Marshall from Chugach Electric Association,Sam Matthews from Homer Electric Association with the designees fromm&Golden Valley Electric Association and Anchorage Municipal Light &Power to be added at a later date.The motion further identified.

The seventh item of business was the Start-Up Subcommittee.It is the Operating Committee!S,concensus that the APA do the organizingoftheStart-Up Subcommittee directly through the utilities. Bob Orr made the request for any other formal actions required at the Committee at this time.It was noted that Dispatch/SchedulingSubcommitteemeetingwillnotbescheduleduntilafterthenext Operating Committee meeting.It was also noted that there was noOresponsereceivedfromtheAlaskaPowerAuthorityconcerningtheIntertiesDataLink'Operating Philosophy and there were no otheractions. O AFIOC Minutes May 9,1984 Page 6 Under the agenda item of Subcommittee Assignments,it was noted that the assignments have been made previously,the SCADA/Metering participation is to be at the May 24,1984 meeting with APA and Gilbert-Commonwealth.It was recommended that the Machine/Ratings Subcommittee have a meeting at the direction of that Subcommittee's Chairman.There were no further Subcommittee assignments. The next item of business was to discuss the agenda for the next meeting which is enclosed. THE NEXT FORMAL MEETING IS SET FOR JUNE 14,1984,9:00 A.M.AT THE MUNICIPAL LIGHT &POWER CONFERENCE ROOM.

Bob Orr motioned that the minutes from the previous meeting be adopted as written.John Marshall seconded the motion.The mem- bers present unanimously approved the motion. After a brief discussion,Bob Orr motioned for the meeting agenda as written to be adopted.Keith Sworts seconded the motion.The members present unanimously approved the motion. Under Committee Correspondence and Reports,the Committee received no correspondence since the last meeting.Chairman Orr read two letters to the Operating Committee which were sent to the Alaska Power Authority since the last meeting.(See attached.) The Committee then heard Subcommittee reports.The SCADA/Metering/ Communications Subcommittee did not meet since the last Subcommittee meeting held in March.However,Bob Orr noted that two meetings were held with Gilbert/Commonwealth &Assoc.which allowed the utilities and Gilbert/Commonwealth &Assoc.to discuss the Intertie SCADA and Communications and specifically the DEC Net System.The-first meeting was held on April 6,1984 and it reviewed the data and control requirements packet furnished by Gilbert/Commonwealth.The second meeting was held on April 16, 1984 and it was a continuation of the discussions and progress made at the first meeting.It was noted that a third meeting had been planned and was tentatively set for May 24,1984. At 9:45 A.M.Hank Nikkels and Sam Matthews joined the meeting. Marvin Riddle reported on the activities of the Dispatch/Scheduling Subcommittee.The Subcommittee met at Municipal Light &Power on Tuesday,April 14,1984.Marvin reported that the Subcommittee is recommending that the full Operating Committee adopt NERC Operating Guides 1 and 6 as modified by the Dispatch/Scheduling Subcommittee, The Subcommittee had been previously directed to review these two Operating Guides. =z AFIOC Minutes April 18,1984 Page 2 Marvin also reported on the Dispatcher/Training Program set to begin in late May.He provided the Operating Committee par- ticipants with a copy of the University of Alaska-Fairbanks Course Outline furnished by Dr.John Aspnes.(See attached.)Aspnes will also send a cover letter to the members of the Subcommittee, concerning the Course Outline.Marvin also reminded the Operating Committee that the first of three Dispatcher/Training sessions will begin on Tuesday,May 29,1984.This is due to May 28,1984 being Memorial Day.The second and third training sessions will run on a Monday through Friday basis.Marvin also indicated that he was still awaiting a Management Overview Plan from Dr.Aspnes. The Machines/Ratings Subcommittee did not meet since the last Operating Committee meeting took place.Hank Nikkels did indi- cate,however,that the Subcommittee is proceeding with the three graph concept for machines,generator and composite ratings.He also noted that it will require two scales to be used due to the wide range between large and small machinery. The Reserves/Loadshed Subcommittee also met on Tuesday,April 17, 1984 at Municipal Light &Power.Tom Martin was substituting for Ray Duncan at today's meeting and furnished the minutes from the Tuesday Subcommittee meeting.Tom noted that the Northern Rail- belt Utilities have different starting point loadshed frequencies than do the Southern Railbelt Utilities.He also noted that ML&P and CEA plan to continue the use of on-line spinning reserve. FMUS and Golden Valley indicated that they will be using a com- bination of on-line spinning reserve and computer assisted loadshed. Bob Orr noted that he wasn't necessarily in agreement with the last sentence of the last paragraph of the minutes furnished by the Reserves/Loadshed Subcommittee.He felt the system still had to be modeled and not just tested through experience. BOB NOTED THAT ONLY GOLDEN VALLEY ELECTRIC ASSOCIATION HAD FURNISHED A WRITTEN POSITION ON RESERVE UTILIZATION AND RESERVE OPERATING PHILOSOPHY.ALL PARTICIPANTS WERE DIRECTED AT THE PRIOR MEETING TO PROVIDE THIS INFORMATION. The Alaska Power Authority was not yet present for an Intertie Status Report at this point.Bob Orr indicated this item would be held for later in the meeting to allow for APA to provide an update, There were no visitors present at the meeting,nor were there any requests for appearances, The Committee had no old business to conduct at this meeting. AFIOC Minutes April 18,1984 Page 3 At 10:20 A.M.,the Operating Committee recessed for work session, The General Electric SVS presentation,which has been on the agenda for several sessions,again did not take place. Turning to SCADA/Metering/Communications,the participants seemed to indicate there is still some confusion about how the Intertie Data Link will come together.After discussion,participants reached an understanding that the data link will be a point-to- point (series)instead of a party line (parallel)interface be- tween the participants.This was an important issue to participants as they are preparing to purchase software and hardware for the DEC Net System. The participants then briefly discussed Dispatcher/Training and the up-and-coming UAF Dispatcher Training Seminars.Participants also discussed the use of training films and it was learned that both ML&P and G.V.E.A.are pursuing the purchase of video cassette training films from the firm of Leighton and Kidd. At approximately 11:00 A.M.,Mike Yerkes joined the meeting and Chairman Orr reconvened the meeting in full session to allow Mike to furnish an Intertie update.Mike briefed the Committee on the Status of the recent veto of the supplemental funding for the Intertie.Mike noted that the southern half of the overhead transmission line is nearly complete.He reported that the contracts for the Healey,Goldhill and Douglas Substations are signed.The Teeland Substation contract is under CEA review. Mike noted that he has instructed Gilbert/Commonwealth &Assoc.to work very closely with the Intertie Utility participants to resolve the.concerns the utilities have,particularly in the area of data communication and control.Mike also noted that the Alaska Power Authority has written to the Utilities addressing the reimbursement aspect of the SCADA communications required for the Intertie.He indicated that APA could not sign off on the SCADA system requirements until Gilbert/Commonwealth makes a recommen- dation and there is an indication that the utilities are in full agreement.Bob Orr at this point noted that the utilities were reluctant to go much further until APA acknowledges the initial approach the utilities are proposing.Mike again reiterated that he felt the utilities were not yet entirely in agreement as to the course of action the utilities want to take in the SCADA com- munications package. Mike also reported that the latest revision of:the Alaska Intertie Draft Contract was mailed out and the next Manager's Meeting will be held at ML&P on Friday,April 27,1984, O AFIOC Minutes April 18,1984 Page 4 Bob Orr then asked Mike for comments on the Operating Committee Budget which was furnished by letter to APA.Mike noted that the budget cannot be established until the Operating Committee is for- mally established at contract signature time. At 11:45 A.M.,Mike Yerkes asked that he be excused as he had to make a trip to Juneau in the afternoon, Bob Orr suggested that each Operating Committee participant look at the latest Alaska Intertie Draft Contract as it impacts the Operating Committee and the Operating Committee budget. Mike Massin motioned to adjourn for lunch at 12:00 P.M.Keith Sworts seconded the motion.The members present unanimously approved the motion. The Operating Committee reconvened in work session at 1:40 P.M. The Operating Committee participants then reviewed two of the Leighton and Kidd demonstration video cassette tapes,which Municipal Light &Power had obtained.There was favorable par- ticipant response to the tape preview.The Operating Committee then turned to Dispatch/Scheduling and Hank Nikkels brought discussion on the need for standards for operators as it applies to maintaining status and notification for such things as main- tenance schedules.He felt this should possibly go toa Subcommittee for further discussion.Bob Orr also felt there was a need to have composite heat rate curves to allow utilities to better utilize their generating capabilities in a more economicmanner.>:' The Operating Committee participants then reviewed the Operating Guides 1 and 6 furnished by the Dispatch/Scheduling Subcommittee prior to formal Operating Committee approval. Hank again reiterated that the Machines/Ratings Subcommittee was pursuing the rating curves as indicated during Committee Reports earlier in the morning. Again,turning to Reserves/Loadshed,both Golden Valley Electric Association and Municipal Light &Power are not willing to support the last two sentences of the last paragraph of page 2 of the minutes of the April 17,1984 Reserves/Loadshed Subcommittee meeting at ML&P.Both still feel all the participants should be prepared to commit to a reserves and loadshed plan at the outset of the commercial operation of the intertie, AFIOC Minutes April 18,1984 Page 5 Turning to budget matters,the Operating Committee participants were again urged by Chairman Orr to review the latest Alaska Intertie Draft Contract as it pertains to the Operating Committee and in particular the Operating Committee budget. At 2:50 P.M.,the Operating Committee returned to formal session. Marvin Riddle motioned for the Operating Committee to adopt the Operating Guides 1 and 6 as modified by the Dispatch/Scheduling Subcommittee.Mike Massin seconded the motion.The members pre- sent unanimously approved the motion.(Attached are the approved Operating Guides 1 and 6.) Bob Orr then motioned for the Operating Committee to make a formal request to the Alaska Power Authority in writing for a study on Spinning Reserve/Loadshed Coordination for the interconnected par- ticipants.Continuing,the motion would also request that a meeting with APA and the utility participants be set up concurrent with the Reserves/Loadshed Subcommittee meeting to be held on May 8,1984 at 9:00 A.M.at Municipal Light &Power.Study criteria would be set forth at the meeting.Keith Sworts seconded the motion.The members unanimously approved the motion, The Committee then turned towards establishing assignments for the various Subcommittees.

March 21,1984 AFIOC Minutes Page 2 Bob Orr then motioned to adopt the agenda as modified.Mike Massin seconded the motion.The members present unanimously approved the motion. The meeting then continued with Dr.John Aspnes furnishing a pre- liminary proposal to the Operating Committee which would have the University of Alaska-Fairbanks conduct a dynamic stability study of the Anchorage-Fairbanks Interconnected Power System.Dr. Aspnes then reintroduced Mr.Harry Beck,who would be the graduate Student performing the studies.The Operating Committee members then discussed amongst themselves and with Dr.Aspnes,the method by which the funding would be provided for the study which would be conducted.The committee members discussed at length the features of the proposed study and the benefits which the study would provide to the Operating Committee and the Interconnected Utilities.The proposal furnished by Dr.Aspnes was well received by the Operating Committee. Dr.Aspnes then reintroduced Mr.Robert Merritt from the University of Alaska-Fairbanks and the two of them proceeded to discuss the dispatcher training courses which will begin on May 29,1984.There will be three sessions of the dispatcher training course each lasting a week.Dr.Aspnes indicated that UAF would not be able to do four dispatcher training courses during 1984. The UAF dispatcher training courses will follow the Western States Coordinating Council Dispatcher Training methodology and UAF will also furnish course material and use of the UAF Electrical Engineering power laboratory.Dr.Aspnes and Mr.Merritt will furnish the Operating Committee with a detailed outline of the proposed dispatcher training course during the up and coming UAF Spring break.Discussion then took place regarding the possibi- lity of having a one day executive seminar for the various utility Management supervisors involved in dispatcher functions.Marvin Riddle noted that he had furnished the Alaska Power Authority with information on the Golden Valley Electric Association Dispatcher Simulator Training System and that the four dam pool operators are interested in future dispatcher training courses.Questioned further,Dr.Aspnes indicated that the dispatcher training course Outline would be ready approximately April 1,1984.The Operating Committee members indicated their preference to see the outline prior to the next regular operating committee meeting in April. Indications are that approximately 38 people will be attending the dispatcher training courses which begin at the-end of May.The consensus of the Operating Committee members was that the 1984 dispatcher training courses would be the first of several yearly training sessions in which the utilities would be participating. March 21,1984 AFIOC Minutes Page 3 Under Committee Correspondence and Reports,the committee received no correspondence since the last meeting and proceeded to hear the various subcommittee reports. Bob Orr reported on the activities of the SCADA/Metering/Communica- tions Subcommittee which met on March 20,1984 at the Fairbanks Municipal Utilities System conference room.Bob furnished minutes of the meeting (see attached).Hank Nikkels indicated that ML&P would also like to be involved in the APA/CEA/Golden Valley Electric Association meeting on the Data Link Requirements. Marvin Riddle reported on the activities of the Dispatcher/Train- ing Subcommittee meeting which was also held at the Fairbanks Municipal Utilities System conference room on March 20,1984. Marvin Riddle also furnished handouts and minutes from the subcom- mittee meeting (see attached)and turned his discussion over to Hank Nikkels for review of the hand-outs and minutes.Hank Nikkels stressed the concern of the subcommittee regarding the APA (Federal)Eklutna line as it applies to power flow and metering during non-standard configuration of the southcentral intercon- nected system.Ray Duncan indicated that the hand-out furnished by Marvin was the proposed Chugach Electric Association dispatch terminal screen format and was for discussion purposes only. John Spence then reported on the activities of the Machines/Rating Subcommittee which also met at the Fairbanks Municipal Utilities System conference room on March 20,1984.John questioned whether any other utilities or organizations have previously done a Machines/Ratings handbook.If so,it would be a good starting point for the Machines/Ratings Subcommittee.He also noted that the Subcommittee hopes to have a draft for the next monthly Operating committee meeting. Because the Alaska Power Authority was not represented at the meeting,no intertie status update report was given. There were no visitors present at the meeting (except UAF),nor were there any requests for appearance other than the UAF presentation. The committee had no old business to conduct at this time, The committee adjourned for a break at 10:50 A.M.and the meeting resumed again at 11:00 A.M. Turning to new business,the committee then proceeded into work session, O March 21,1984 AFIOC Minutes Page 4 No G.E.-S.V.S.presentation took place at the meeting. The committee then began a discussion on SCADA/Metering/Communica- tions.Tom Martin had several questions for Golden Valley Electric Association regarding their SCADA/Dispatch/Computer System.It was noted that GVEA was using the PTI Loadflow Program.A brief discussion then took place regarding the various utilities com- puter systems and the types of memory systems that the various computer systems employed.The Operating Committee members discussed at length the GVEA loadflow package and the availability of Other utilities using the GVEA load package. Several Operating Committee members expressed their concern about the metering on the APA (Federal)Eklutna line metering.After lengthy discussion the consensus of the Operating Committee was that the Eklutna line metering problem was not an issue to be resolved by the Operating Committee but that it would be benefi- cial if the southcentral utilities could meet with the APA (Federal)Eklutna people to discuss the metering problem. Discussion then turned to Dispatcher/Training and Marvin Riddle indicated that he would coordinate with Dr.John Aspnes to sche- dule an executive meeting to review the draft course outline for the Dispatcher/Training courses to be held in May.It is possible a review meeting may not be required depending on the detail fur- nished in the course outline. Bob Orr then motioned for the meeting to adjourn for a lunch break and Keith Sworts seconded the motion.The members present unani- mously approved the motion. The committee recessed for lunch at 11:55 A.M.and reconvened at 1:30 P.M.,still in work session. Turning to Dispatch/Scheduling,Ray Duncan then discussed the Chugach Electric Association Interchange/Scheduling Screen Format handout which was furnished to the Operating Committee during the Subcommittee report portion of the meeting.The Operating Committee members felt that the CEA Dispatch/Scheduling Format furnished should be referred back to the Dispatch/Scheduling Subcommittee members on an individual basis with the individuals furnishing comments directly to Ray Duncan,PLEASE NOTE THAT RAY REQUESTED THAT COMMENTS BE FURNISHED TO HIM WITHIN A COUPLE OF WEEKS BECAUSE HE HAS A DEADLINE TO MEET WITH THE CEA SCADA/ COMPUTER VENDOR. Turning to Machines/Ratings,the Operating Committee continued discussion carried over from the Subcommittee report regarding the Machines/Ratings Operating Manual which is being developed. Committee members expressed a need to develop a living document that could be continuously updated,say every six months and allowforchangesinMachines/Ratings. March 21,1984 AFIOC Minutes Page 5 Bob Orr then provided the Operating Committee members with a draft budget for the Operating Committee and the Operating Committee Subcommittee for the coming fiscal year.Recommendations were made to include in the proposed budget secretarial/typing/coping assistance and inclusion of the UAF Dynamic Stability Study. Discussion took place regarding the election of new officers and methods by which officer positions could be rotated amongst the various utility participants. The meeting then reconvened in full session and the committee pro- ceeded to take formal action on several items. Bob Orr motioned that the Operating Committee prepare a letter to the Alaska Power Authority (Mike Yerkes)stating that the Operating Committee understands that the Alaska Power Authority is doing further studies on the Data Link and request that the full Operating Committee participants meet with APA (Mike)to discuss the scope of the study.Participants included in the meetingwouldbeCEA,ML&P,FMUS and GVEA.Sam Matthews then seconded the motion.The members present unanimously approved the motion, Mike Massin then motioned that the members of the Dispatch/Sched- uling Subcommittee review the proposed CEA Accounting and Scheduling Screen Format Displays furnished by Ray Duncan and pro- vide their comments directly to Chairman Ray Duncan by March 30, 1984.Keith Sworts seconded the motion.The members present una- nimously approved the motion.
