This system consists of a data processing computer with significant data storage capability, buffered and filtered input/output channels, and monitoring and evaluation software. The system is capable of being operated remotely and will automatically store both pre-disturbance and post-disturbance data based upon predefined data duration and disturbance triggers. The IS system has the capability to monitor up to 74 channels of data at approximately 4000 samples per second with no effective phase shift (A<.06 milliseconds) between channel one and seventy-four. Prior to installation and commissioning of the Instrumentation System, the unit completed an on-line test consisting of approximately 300 hours of continuous operation. Throughout this 300-hour test the unit was randomly triggered, and caused to collect and store data. Since the installation of the IS in January of 1999 it has been successfully collecting and storing data following system disturbances. The Instrumentation System can now be considered a stable data collection platform. The IS will be used to gather data generated by the tests outlined in this document. The objectives of this testing program are fourfold. The first is to determine which, if any, of the components within the Woodward 501 Digital Governor (Governor), PTI Power System Stabilizer (PSS) and the Fuji Exciter contribute to the undamped control response of the turbine-generators. The second is to determine which components within the governor and PSS that should dampen such oscillations, fail to do so and why. The third is to verify that each of these components is modeled as accurately as possible in the PSS/E software. The fourth goal of the program is to gather sufficient data to perform sanity checks on solutions to the control instability and performance optimization problems that the test team will propose as a part of the Bradley Lake Control and Instability Action Plan. These solutions will be modeled in PSS/E and Matlab and checked against the response data captured during this test procedure. The test program uses traditional dynamic control system analysis techniques to evaluate the response of the various Bradley Lake Control System components. These responses can then be compared to the corresponding responses of the PSS/E and Matlab models of the actual power system components. The step and sinusoidal forcing functions will be used to derive these benchmark responses. The step function is a time domain function that provides information on both the stability and resonance of the subject control device. The sinusoidal function (frequency sweep) is a frequency domain function that provides information on the stability, tracking, resonance, and frequency response of a subject control device, over a selected range of frequencies. In addition to it’s data collection capabilities, the IS has the capability to generate analog output forcing functions, both step and sinusoidal frequency sweeps. These outputs are applied to the governor via I/O boards designed and installed by Woodward Governor in June of 1998. These signals can be applied to three locations within the governor via two 3/29/99 6:35 PM \\CEANW2\VOL1\CEADIR\TD\ANDIH\DATA\WORD\Bradley\TESTPLA \execut~1 .doc 4 of 85 Draft-Draft-Draft Draft-Draft-Draft input channels. These input channels are defined as the speed loop add block and the deflector position setpoint junction.

Testing Techniques The test procedures attempt to isolate various components of the governor and apply forcing functions to their inputs while simultaneously measuring their outputs. Due to constraints in the I/O hardware and feedback/feedforward interrelationships within the governor, complete component isolation is frequently impractical. Figures two through six, below, are control block diagrams that identify the control components that are isolated and evaluated in the test procedures. In addition, these diagrams show the paths between control components that will not be isolated during testing.(Figures five and six, deflector servomotor and PSS will be added later.) Figure two shows the complete Governor Control Block Diagram when in needle mode. In needle mode there are two areas of interest in our analysis. These areas are defined by the basic functionality of the governor. The governor when in needle mode uses only the 3/29/99 6:35 PM \\CEANW2\VOL1\CEADIR\TD\ANDIH\DATA\WORD\Bradley\TESTPLA \execut~1.doc 5 of 85 Draft-Draft-Draft Draft-Draft-Draft needles to raise and lower the units power output, unless an overspeed condition occurs. If an overspeed condition occurs, then the deflectors are used to rapidly decelerate the unit. Therefore, analysis of normal needle controlled load acceptance and reduction can be confined to needle variables and the deflector control components ignored. These needle variables are shown in the Lower Block of the Governor Control Block Diagram (Figure 3). tomy i Setpoint To Servomotor +Al Ssec W+Al- x — Nee & S/T rp see” os Q gel TH egend ,. «Speed tree Per nt este Now Are aes Niede Fenton C, -tweee Drove w"Necae Speed Relerence = Detector Speed Reference = actus!

Analysis of the governor’s response to overspeed conditions can be confined to deflector variables and, due to their slow response, the needle variables can be ignored. The deflector variables are found in the Upper Block of the Governor Control Block Diagram (figure four). Despite the apparent disassociation of the needle and deflector variables, it should be noted that, whenever speed error signals are applied to the speed loop add block, they are seen at both the upper and lower speed-error summing junctions. Therefore, there is always some feed back between the Upper and Lower Blocks.

Although deflector mode is internally decoupled from needle influence, there is a relatively slow feedback loop through the Pelec variable, a watt transducer measuring unit output power. As in the deflector overspeed component testing, needle response times are slow enough that needle feedback can probably be neglected with little effect overall accuracy.

Installation and Commissioning Commissioning of the Instrumentation System, already complete, consists of connection of the IS to previously installed plant wiring, Woodward analog I/O boards, and the PTI Power System Stabilizer. Once the Instrumentation System was installed and an end to end checkout of each circuit was performed. Remaining commissioning consists of several tests to determine the relationships between analog input voltages and governor control quantities, as well as determination of minimum operating parameters for the governor hydraulic system. 3/29/99 6:35 PM \\CEANW2\VOLI\CEADIR\TD\ANDIH\DATA\WORD\Bradley\TESTPLA \execut~1 .doc 8 of 85 Draft-Draft-Draft Draft-Draft-Draft Off-line Testing Off-line testing will be performed with the unit off-line, generator breaker open, the needles completely closed, and the turbine pit dry. When testing includes signal applications that are invasive to the control components, we will request that the manufacturer provide a technical representative on-site during the testing. The off-line testing will consist of application of IS analog input forcing functions to the speed error summing junctions, the deflector position setpoint summing junction and the input of the Power System Stabilizer. Data will be collected on all relevant Woodward Digital 501 Governor, PSS and Exciter outputs, as well as, some control loop and signal conditioning points within the Digital 501 Governor. The collection of response data at the control loop and signal-conditioning level will allow us to compare the response of the Bradley plant to PSS/E’s simulated response, on a control block by control block basis. Frequently this comparison is made through and intermediate control analysis tool known as MatLab. This ability to compare internal control loop and signal conditioning responses will provide the following benefits: e First, good agreement between the plant and PSS/E at the control block level implies that we can expect good agreement between the plant and PSS/E at the power system level. Furthermore, if such agreement exists we can be relatively confident of our ability, if required, to initiate an unstable condition during the on-line tests from a predefined set of system of conditions and accurately predict a response. e Second, with good agreement at the control loop/signal conditioning level we can manipulate governor variables within the model in order to optimize the Plants control response. e Third, in the event that there is poor agreement between the governor and our simulations, these detailed results will provide a troubleshooting road map to areas of the model that must be corrected, in order that we may more accurately simulate the actual Bradley system. On-line Testing Due to the nature of the on-line tests and the unstable nature of the plant, there is the possibility that the interconnection will experience severe power swings and potential loss of load. We will attempt to minimize the ramifications of this contingency by coordinating the on-line testing with the large industrial and commercial customers on the Kenai Peninsula. In addition , there is as always the possibility that unstable operation of the plant may cause damage to the turbine generator or the plants mechanical infrastructure. The likelihood of this is mitigated by numerous protective schemes that are integral to the plant’s infrastructure and control systems. In addition the test plan is being reviewed and approved by Stone and Webster Eng., Woodward Governor, and Power Technologies, Inc. On-line testing will consist of similar control system tests to those performed in the off- line testing and several additional tests outlined below. 3/29/99 6:35 PM \\CEANW2\VOL1\CEADIR\TD\ANDIH\DATA\WORD\Bradley\TESTPLA \execut~1.doc 9 of 85 Draft-Draft-Draft Draft-Draft-Draft e Collection of high-resolution deflector verses power data. e Collection of data on deflector position and time delay verses hydraulic pressure for a loaded deflector. e Collection tunnel pressure variation during needle transitions, deflector operation, and power system oscillations. e A small-signal frequency sweep to benchmark the relative magnitudes of the Bradley- Power System oscillating modes. In many cases the magnitude and duration of the applied signal has been modified from that found in the off-line testing in order to accommodate system constraints. As in the offline testing, when these tests require the application of control signals that are invasive to specific control components, we will have manufacturer’s technical representatives on-site.

Story General Manager May-17-99 12:05pm = From-HOMER EL Cc 9072353323 i T-554 P.05/07—-F-371 BACKGROUND In October 1998, Homer Electric Associanon, Inc. (HEA) activated the electromcs to use the fiber optic cable placed by HEA from Homer to Kenai. The fiber optic cable passes though seven (7) substanons operated by HEA and terminates at the HEA offices in Homer and Kenai. One of the goals for HEA’s fiber project is to transport the communications traffic for the Bradley Lake Hydroelectric Power Project (Bradley Project) on a secure, high capacity, and rehable system Currently this traffic is transported over an analog microwave system operated by the State of Alaska, Division of Communications (DivCam). This tatfic is carned throughout the Kenai Peninsula and Anchorage, providing control, monitoring, and voice access for the Bradley Project. For the transport of these circuits plus VHF radio circuits DivCom is currently billing the Bradley Project $129,578.79 per year. This is being increased 60% to $207,369.06 per year for FY 2000. PROPOSAL HEA proposes to transport the circuits from Bradley Lake 10 Bernice Lake and maintain the VHF radio system for $90,000 per year for S years. Chugach will transport the circuits from Bernice Lake to Anchorage at their tarified rates, $27,684 per year. This will represent savings of approximately $90,969.06 in FY 2000 plus protects the Bradley Project from increases for a period of 5 years. {DIVCOM — $207,369 HEA $90,000 CHUGACH _ $27,684 SAVINGS $90,969 The basic routing for the microwave system today is: Bradley Lake Powerhouse to Bradley Mountain Bradley Mountain to Seldovia Peak. Seldovia Peak to HEA in Homer, Anchor Point, and Diamond Ridge Substation. Anchor Point through multiple repeater sites then to DivCom in Anchorage. DivCom in Anchorage to Chugach Dispatch WUbwwo The additional sites used as repeaters by DivCom are not significant to HEA’s plan and will not be addressed here. Several major components of the equipment used by DivCom to transport these circuits are awned by the Bradley Project.

Chugach will provide the details for the Bermce Lake to Anchorage section. Each of the first two sections will be addressed mm detail in this document. In summary, the plan 1s to reulign the Bradley Mountain and Homer microwave radios, directing them towards each other, and move the circuits onto HEA’s SONET system. The circuits will be transported over fiber to the Bernice Lake Substation. Chugach will then carry the circuits into their dispatch center. PLAN SUMMARY This. document will summarize the plans for moving the Bradley Project’s communications circuits from the analog microwave system operated by DivCom 10 HEA’s fiber network. Detail Tor two of the three segments, Bradley Powerhouse to Homer and Homer to Bernice Lake, have been provided to the Bradley Lake Project Operauons and Dispatch Committee. Details for the third segment will be provided by Chugach. A general summary of the third segment will be provided. Segment 1-Bradley Lake Powerhouse to Homer Segment | consists of the path from the Bradley Lake Powerhouse through Seldovia peak to Homer. Figure 1 shows the current configuration of the DivCom microwave system. This path also connects to Diamond Ridge and Soldoma Substation. These connections will be addressed as part of Segment 2. HEA has researched options to adjust this segment to more effectively connect to the fiber network. The microwave and fiber optic equipment at the Bradley Lake Power House, Bradley Mountain Microwave Site, and the Homer Microwave site is owned by the Bradley Project. The option chosen by HEA to migrate to the fiber network 1s to realign the Bradley Mountain and Homer microwave systems to directly communicate, This realignment, as all microwave paths, will require a clear line of site path. A visual inspection from the top of the tower at Homer indicates that this path is usable. HEA 1s currently verifying the existence of clear line of site by flashing the path and performing path calculations. Once the realignment is complete, the microwave system will deliver all exasting circuits, with one exception, to HEA’s Homer office where they can be mulnplexed onto the SONET network. The one circuit that will not be delivered is System Channel 25, HEA Voice Seldovia Ringdown. This circuit is no longer required because Seldovia will no longer used as a repeater site. Segment 2-Homer to Bernice Lake Segment 2 consists of the path from HEA’s office in Homer to HEA’s office in Kenai via HEA’s SONET fiber network and a leased T-1 circuit from HEA’s Kenai office to Bernice Lake substanon, The HEA fiber network passes through Diamond Ridge and Soldoma substations. May-17-98 12:06pm = From-HOMER EL c 9072353323 1-554 P.07/07 —-F-871 HEA will add additional equipment at all of the sites necessary to allow for the multiplexing/demultiplexing of the circuits currently on the microwave system to and from the HEA SONET network This equipment will consist of additional SONET multiplexers at Diamond Ridge and Soldoma substations. Smart channel banks wil] be added to each site to muluplex the existing analog circuits into digital DS-1 circuits for transport aver the SONET network. These smart channel banks will provide the required interfaces for all existing circuits being transported from Bradley Lake. They also provide for expandability to digital data circuits for future use. As the communication requirements for Bradley Lake grow, additional bandwidth 1s available in both the smart channel banks and the SONET multiplexers. HEA’s SONET network currently has fifty-four ($4) unallocated DS-1 circuits available. This provides a current capacity of 1,296 DS-0 (64kbps-voice grade or digital) circuits, such as those currently in use ut Bradley Lake. The HEA system can be m-service upgraded to OC-12, adding an additional 252 DS-1 circuits. The limitation on this growth will be determined by the Segment | microwave system. The current analog system could be replaced, at a future time, with a higher capacity digital radio, should st become necessary, The current circuits are not near deplenng the Segment 1 microwave system. Segment 3-Bernice Lake to Anchorage Segment 3 consists of the path from Bernice Lake to Anchorage. This path consists of a SONET microwave system installed and activated by Chugach in 1998. The ODS-1(s) from HEA’s SONET network will be placed on Chugach’s microwave system at Bermce Lake and transported to Anchorage for termination. Details for this segment will be provided by Chugach. Circuit Channelization Plan A channelization plan has been designed to allow for flexibility in future growth and minimize the number of DS-1 circuits required for Segment 3, Bernice Lake to Anchorage. This will reduce the complexity of the cross connects at each location, making the system easier to maintain and upgrade. Maintenance Maintenance and surveillance of the Fiber system is contracted to PTI. FINAL SYSTEM CONFIGURATION As seen in this documem, the HEA plan for wansporting the Bradley Lake Project’s communications traffic consists of three segments. Those segments are made up of existing analog and digital microwave radio and SONET fiber optic systems. Reliability and bandwidth of the communications system 1s improved in several ways, including: Reducing the number of analog microwave radios Using fiber optic cable Using digital microwave Using smart channel banks ee7ee This system will provide virtually unlimited bandwidth for future growth of the Bradley Lake * S e@ ALASKA INDUSTRIAL DEVELOPMENT * AND EXPORT AUTHORITY = ALASKA ie =SEENERGY AUTHORITY SSSEHESEAEE= 480 WEST TUDOR ANCHORAGE, ALASKA 99503 907 / 269-3000 FAX 907 / 269-3044 ALASKA ENERGY AUTHORITY/ALASKA INDUSTRIAL DEVELOPMENT AND EXPORT AUTHORITY Public Notice Bradley Lake Project Management Committee Notice is hereby given that the Bradley Lake Project Management Committee will hold a meeting VIA TELECONFERENCE on Monday, May 17, 1999, at 2:00 p.m., to conduct the affairs of the Committee.

AGENDA COMMENTS Under New Business Item 7 — make a new 7A Bradley PMC Communications Plan that Homer is proposing and then change the Bradley Lake Instability System Test Plan to Item 7B. There were no objections to the changes to the agenda. 6. APPROVAL OF MEETING MINUTES — March 22, 1999 MOTION: Mr. Story moved to approve the meeting minutes of March 22, 1999. Mr. Evans seconded the motion. A voice vote was taken and the minutes were unanimously approved. le NEW BUSINESS 7A. Bradley Lake PMC Communication Plan — Norm Story Mr. Story stated HEA has completed a 90-mile study using 24 strands between Homer and Kenai. Four strands were retained for HEA’s use for communications on the Bradley Project. This makes for significant savings when coupled with Chugach’s new link between Bernice Lake and Anchorage. HEA is proposing to take over the power between Homer and Bradley, and manage, operate, and maintain it to get the signal to Bradley and then to HEA’s private project. We would then take the communications to Kenai where Chugach would take over and link it to Anchorage. Our studies show that this proposal would show a significant savings and profit. He said he is bringing this before the Committee because HEA needs to spend money to set up the in-use equipment to allow this process to take place. Coupled with this is the O&M contract, which comes up for renewal in June, which thereafter becomes a year to year extension. HEA would like to have the project O&M Agreement extended to an additional five years that would couple this section into the original Agreement and make them concurrent. Mr. Stead briefly reviewed the document and discussed the background costs with the Committee. He stated that the Division of Communications provides all of the communications to the project through a microwave link that goes from Bradley to Seldovia and then is transmitted to Homer Electric where void circuits get dropped off for PT| — there are approximately 40 circuits that are carried by the Division of Communications. The project also has approximately 19 VHF radio channels. He said HEA’s proposal is that HEA would take over all of the communications for Bradley Lake, which includes VHF and all microwave signals. Mr. Stead said that HEA has noticed that the Division of Communications has had several outages and it appears to be becoming a more frequent occurrence as the equipment is getting worn out. Mr. Stead said that Chugach is the ultimate end-user with the exception of Golden Valley and ML&P, which basically were several data circuits. HEA will install some additional equipment especially at the Diamond Ridge point — most likely to the sites that control that aspect. For clarification, both towers that HEA are planning on using were installed for and owned by the Bradley Lake Project. HEA will be adding a 20-foot section to the tower at the Homer office, redirecting the antennas so they will directly communicate between Bradley Mountain and the Homer office. The Homer office will pick it up and transfer it to the fiber, which will then carry it into Diamond Ridge, Soldotna, and Kenai, and make the appropriate drops. We are currently working on a contract with PTI to then carry this fiber over to Bernice Lake which then goes over to Chugach. Bradley Lake PMC Meeting Minutes May 17, 1999 Page 3 of 6 Mr. Morgan asked that if what has been happening between the powerhouse and HEA’s office is still continuing to be microwave? Mr. Stead responded that HEA will continue to microwave, except one of the hops will be cut out. The current situation is a two hops system that goes from Bradley Mountain to Seldovia and then Seldovia to Homer office, Diamond Ridge, and Anchor Point. Homer office and Diamond Ridge are operating as radio and continuing to carry the majority of the traffic up from Anchor Point into Anchorage. Our current plan is to go from Bradley Mountain to the Homer office — we have verified that the path is good between Bradley and Homer. Mr. Story said he has not had a chance to speak with Stan (AEA) regarding this proposal and the Agreements, however, once the PMC has given the go-ahead we will need to conclude our discussions relative to the state’s communications system with the AEA because we do contract with the state AEA. | am under the assumption that Stan is working on that issue from the O&D committee side. He said he has developed a draft proposal-amendment and believes a copy went to Dennis McCrohan (AEA), and Ron Saxton, representing the PMC management group. It would be the understanding that it would have to be followed up between the state and Homer Electric, and in fact, the PMC for concurrence or ratification. He said that, as seen from the study, there is considerable savings for transporting the signals - we save approximately $90,000 a year on the Division of Communications projected rate for this year. Meera Kohler and Hank Nikkels with ML&P joined the meeting at this time. Mr. Saxton said that the Homer O&M contract is a contract between Homer and the Energy Authority to operate the project, but the PMC does have to agree to it. The contract is up for renewal and | am assuming that the state intends to renew Homer as the operator and that all of you are agreeable with that. If this is not true, then we need to put that out on the table. Since, however, that the O&M contract itself does not provide for the rate payment than it is still subject to the budget process. If AEA and the group intends to renew Homer's O&M contract then it is easy enough to simply amend that contract that would add to their duties providing those communications, and for that sole part — the communications part — adding some payment terms. Mr. Bjornstad asked whether there will be a motion to recommend approval. Mr. Saxton replied that what Homer wanted was approval for the idea that they are going to provide the communication service at this rate so that they can make some decisions. The PMC would not approve the O&M contract. The assumption is that we will amend the O&M contract to reflect the new communications duties if that is what the group approves today. Mr. Story said that if we can approve the communications then we can begin to spend money to develop our end of it and then direct AEA, HEA, and the PMC attorney to complete the amendment of the O&M agreement which will include the communications piece. It was briefly discussed on whether the segment from Chugach would be handled separately or together without a contract — they would become subcontractors to us. | would offer this to all parties to consider making it where you deal with one entity. Then we can work that out with Chugach and just include it as a part of this Agreement. However, if you wish to have a separate Agreement with Chugach we will work that up. Mr. Bjornstad said that he would choose whichever contract is cleaner. Ms. Kohler said that this concept was talked about at the last meeting and it hasn't really changed much. She said she has no problem with it. Bradley Lake PMC Meeting Minutes May 17, 1999 Page 4 of 6 MOTION: Mr. Story moved to approve Homer Electric’s proposal to provide the communication service with a cost of $90,000 per year for a term of five years as detailed in the proposal, and that Homer Electric, AEA, and the PMC attorney be directed to complete an O&M Agreement extension for five years and include the communications segment. Ms. Kohler seconded the motion but added the suggestion that the $90,000 a year actually include the Chugach portion of $27,684. Mr. Story amended the motion to include both pieces to get the signals from Bradley to Anchorage, and that we will negotiate with Chugach as a subcontractor. Ms. Kohler seconded the amended motion. Mr. Evans asked whether there was an issue on when it was implemented, when we contract with the state, was that for the year or at the beginning of a new fiscal year? Mr. Bjornstad said the Agreement ends at the end of June, we have to renew it for the new fiscal year. Mr. Story affirmed this and stated that an amendment is needed for an additional five years. He said the O&D committee has communicated that they would like to have that by October and that is the reason why we want to get early approval so we can begin to develop our end of the process. Mr. Evans asked whether anybody checked with the state. He asked if we are allowed to contract with them for three months and then only pay the 3/12" of the contract with them. He asked that when we get near the end of the contract does anybody now of the provisions to get out of that. Mr. Story responded that regarding Homer Electric's proposal that we would begin to expect payment for our payment when the Division of Communications budget year ends. Our goal is that we have our work completed and ready to pick up that communication. After that, if there is a problem, and the system has to be worked out and we have to be on the Division of Communications system a little bit longer then we have to run that down and see what would be necessary. | am sure we could work something out, they are not just going to cut us off. Mr. Saxton said that the Division of Communications contract ends July 1. We then have the window from July 1 to October where we could end up with 0 or maybe 2 servers for the next fiscal year. Mr. Evans said that Mr. Story indicated that he would have his commercial ready to go October 30. If so, then we will be on those guys for a couple of months. Mr. Saxton said we will be on the Division of Communications from July 1 to October — we are committed to the Division of Communications for the whole fiscal year. Mr. Evans said he wanted to make sure someone addressed that issue. Mr. Cooley said that he believes that the Division of Communication is a monthly rental fee and that there is no contract. As such, you would just need 30 days notice to let them know that you do not want the circuit anymore. Mr. Saxton requested Mr. Cooley confirm that belief because if this is the case then we could end up paying for double service for a year. Bradley Lake PMC Meeting Minutes May 17, 1999 Page 5 of 6 Mr. McCrohan said that is also his understanding. He said that this could be taken care of with the discussions regarding the amendment to Homer's contract. In response to Mr. Story, Mr. Evans stated that July would be the end of the contract — it would be the end of the budget year. Mr. Story said that it will have to be verified that they will go month-to-month with us and give them 30 days notice when we are ready to cut over and our costs will not start until we cut over. Hearing no further discussion, Mr. Bjornstad requested a roll call vote. A roll call vote was taken and the motion passed unanimously. 7B. Bradley Lake Instability System Test Plan — Executive Summary -- Hickey Mr. Hickey stated that the test plan for the Bradley Lake Project was completed and sent out to Stone & Webster, Power Technologies, and Woodward Governor approximately six weeks ago. They submitted comments on the test plan and those comments were incorporated into the plan on Saturday. We will be sending the revised plan to the people who will be participating in the testing. Mr. John Yale will be on-site while the testing is being done at the plant. We have set up a test schedule and the testing should be starting on Wednesday the 19". We tried to schedule any testing that would have any effect on the system in the evenings so we will be doing some load rejections and load acceptance Wednesday evening. Thursday evening, Power Technologies is scheduled to do power system stabilizing testing and the tunnel transient pressure evaluation. Friday evening, we will be doing the deflector vs. power curves and then evaluate some of the gaining sensitivity on Saturday morning. The testing should be complete by Saturday afternoon. Woodward Governor, Stone & Webster, and Power Technologies will be on site whenever we are testing any of their equipment. Basically, Woodward Governor and Stone & Webster will be on site for the entire duration of the test, along with Electric Power Systems who participated in the original analysis of the system stability problems. Mr. Hickey stated that if the projections for the next week come out correct, we will be at $382,600. The original budget was $382,015. Mr. Hickey stated that he would like a motion from the general managers or from the project management committee to approve going ahead with the testing this week. Mr. Stead said that he would like to move some of the testing schedule around. ML&P had some concerns and questions about having both units off line at the same time. We would like to do some of the more rigorous testing in the morning rather than the evening. Mr. Hickey stated they are flexible with the testing schedule. Mr. Nikkels said the morning testing would be fine. There will be more equipment on line in the morning so it will take a bigger bump. Mr. Hickey said that they are going to try to run pretty much everything on the Kenai while they are testing this. They will maximize the spin on the Kenai. Bradley Lake PMC Meeting Minutes May 17, 1999 Page 6 of 6 Mr. Story stated that regarding the timing of the testing where the system may be in jeopardy during certain phases, we believe that off-day peak would be the best for us as far as our services go. We do understand, however, that the utilities wanted to have less equipment up and as many people in place as possible so they were focusing on it during the day. We just want that to happen in the morning so if we do have a problem we have the opportunity to get it back up before most of the businesses open. We will work with our industrials here to make sure they know that the testing is going to commence. We need to discuss the scheduling and fine tune it. Mr. Hickey said they are flexible with the testing. Motion: Mr. Bjornstad moved to approve testing the Bradley Lake units within the plants design parameters as outlined in the Bradley Lake test plan. The testing will be scheduled for May 19-22, and details of it will be worked out with the respected utilities. Ms. Kohler seconded the motion. Hearing no further discussion, Mr. Bjornstad requested a roll call vote. A roll call vote was taken and the motion passed unanimously. Mr. Story expressed his thanks to the group for working with us on getting a project that will help us with our communications. We will be saving money for everyone. 8. COMMITTEE COMMENTS A.
