The PMC recognizes that the method of operating the Project may change from time to time in order to accommodate modifications to such licenses and permits. (b) Relationship to Basic Agreements. In the event that any provisions in these Procedures conflict with provisions in any of the Basic Agreements, the provisions in the Basic Agreements shall prevail. (c) Initial Allocation. The Initial Project Energy shall be determined prior to the beginning of each Project Water Year based on known operating limitations, estimates of runoff available from snowpack, precipitation for the May-October period equal to 80 percent of the long-term average, and other pertinent factors, and in a manner consistent with the following: (a) On or before March 1 of each year, the PMC shall meet and establish a coordinated maintenance schedule for their transmission facilities and the Project for the 12-month period commencing with the ensuing June 1. (ii) On or before April 15 of each year, the Authority shall transmit to the Purchasers a preliminary estimate of the amount of capacity and preliminary Initial Project Energy available for the upcoming Project Water Year. (iii) On or before May 1, each Purchaser shall submit to the Authority its forecasted monthly use of its Percentage Share of Initial Project Energy. The monthly energy requirements will be based on the expected Initial Project Energy, as estimated under Section 4(c)(ii), and the coordinated maintenance schedule established in Section 4(c)(i). (iv) Based on the total monthly energy requirements from the Project for all Purchasers, the Page 5 - BRADLEY LAKE ALLOCATION AND SCHEDULING PROCEDURES November 19, 1991 Authority shall perform the Reservoir Operation Model as outlined in Exhibit A and compare the resulting Initial Project Energy with the preliminary Initial Project Energy estimate in Section 4(c)(ii). The Authority shall transmit to each Purchaser the results of the Reservoir Operation Model by May 15. (v) If the results of the Reservoir Operation Model performed above show the expected Initial Project Energy to be different than that assumed in Section 4(c)(ii) above or there is potential for Project Spill, the Authority and the Purchasers shall work together in revising monthly energy requirements such that Initial Project Energy and the sum of the Purchasers’ monthly energy requirements assumed for the Reservoir Operation Model are equal to one another and Project Spill potential is minimized. (d) Revised Allocation. Each month the Authority shall estimate the amount of energy available from the Project for the remainder of the Project Water Year and determine the amount of energy which should be added or subtracted from each Purchaser’s Net Allocation of energy for each month in the remainder of the Project Water Year. In the event the amounts to be added or subtracted from the total Net Allocation then in effect for the Purchasers exceeds 15,000 mWhs, the Authority shall determine the amount of Revised Project Energy for each Purchaser in the following manner: Page 6 (4) The Authority shall transmit to the Purchasers a preliminary estimate of the Revised Project Energy for the remainder of the Project Water Year and the Project Generation to date. (ii) Each Purchaser shall be allocated its Percentage Share of any difference between the new Revised Project Energy, and the then in effect estimate of Project Generation for the Project Water Year. If the result of such allocation is negative, the Purchaser’s Net Allocation shall be reduced by such amount in the next Project Water Year. (iii) The Purchaser shall submit to the Authority its forecasted monthly requirements of the Revised Project Energy. (iv) Based on the total monthly requirements of Revised Project Energy, the Authority shall perform the - BRADLEY LAKE ALLOCATION AND SCHEDULING PROCEDURES November 19, 1991 Reservoir Operation Model as outlined to verify the Revised Project Energy. (v) If the results of the Reservoir Operation Model performed show the Revised Project Energy to be different than that assumed in Section 4(d)(i) or there is potential for Project Spill, the Authority and the Purchasers shall work together in revising monthly energy requirements such that Revised Project Energy and the sum of the Purchasers’ monthly energy requirements assumed for the Reservoir Operation Model are equal to one another and Project Spill potential is minimized. (e) Status of Energy Account. As soon as practicable after the end of each month, the Authority shall provide each Purchaser an accounting of the amount of Initial Project Energy or Revised Project Energy available to each Purchaser in its Energy Account for the remainder of the Project Water Year, along with its best estimate of the potential availability of additional Revised Project Energy and the potential for Project Spill in the ensuing month. If an event occurs during any month which requires the Authority to increase or decrease the amount of Revised Project Energy available to a Purchaser or increases the potential of spill, the Authority shall use its best efforts to provide each Purchaser an interim accounting of the Initial Project Energy or Revised Project Energy available and the amount of such energy which could be subject to spill in the next 30 days. (f) Failure to Refill. If the Revised Project Energy is expected to be 90 percent or less than previous estimates of Project Generation for the Project Water Year, the Authority shall notify the PMC and the Operation and Dispatch Committee. The Operation and Dispatch Committee shall recommend whether to alter the scheduled operation of the Project and the PMC shall then consider the recommendations and adopt, if appropriate, a revised schedule of Project Generation. Any disputes shall be resolved in accordance with the by-laws established by the PMC. (g) Review of Reservoir Operation Model. The methodology and inputs of the Reservoir Operation Model shall be reviewed by the Operation and Dispatch Committee at least every five (5) years and recommendations for changes to the Model provided to the PMC. The Reservoir Operation Model shall be modified, if required, to reflect any changes Page 7 - BRADLEY LAKE ALLOCATION AND SCHEDULING PROCEDURES November 19, 1991 to the permits and licenses that the Project is operated under. The PMC shall have the right to approve any changes made to the Reservoir Operation Model. Section 5. Project Scheduling. (a) General. Each Purchaser shall have the right to schedule during any month an amount of Project Generation not to exceed its Net Allocation for that month. (b) Hourly Schedules. No later than 5:00 p.m. on Thursday of each week (or the preceding day if Thursday is a holiday), each Purchaser shall provide to the Dispatcher a schedule of hourly Project Generation for its use for the following week commencing with 12:01 a.m. Sunday. (c) Minimum Scheduling. If the combined scheduled Project Generation from Purchasers scheduling generation is less than 10.0 mW in any one hour, the Purchasers shall be notified no later than 10:00 a.m. on the following day. The Purchasers shall have until 5:00 p.m. of that day to revise their schedules such that the combined Project Generation is equal to or greater than 10.0 mW. If such revisions still result in a combined scheduled Project Generation of less than 10.0 mW, such Project Generation shall not be scheduled for Project output. (d) Minimum Operations. If, due to operating constraints included in the various permits and licenses that the Project is operated under, the Project must be operated in a manner such that Project Generation is greater than that amount scheduled by all the Purchasers, the amount of Project Generation in excess of that amount scheduled shall be allocated on a pro rata basis to each Purchaser based on its Percentage Share. No Purchaser shall be obligated to take more than its Percentage Share of Project Capability. (e) Reductions in Schedules. If the combined scheduled Project Generation is greater than Project Capability in any hour, each Purchaser’s request shall be reduced during that hour in the following manner: (2) For those Purchasers who have scheduled more Project Generation than their respective Percentage Shares of Project Capability in any hour, the amount scheduled for such Purchasers shall be reduced on a pro rata basis based on the amount scheduled Project Generation exceeds Project Capability. The amount of Page 8 - BRADLEY LAKE ALLOCATION AND SCHEDULING PROCEDURES November 19, 1991 scheduled Project Generation for any Purchaser shall not be decreased pursuant to this Section 5(e)(i) to an amount less than each respective Purchaser’s Percentage Share of Project Capacity. (ii) If after making such reductions in Section 5(e)(i) the combined scheduled Project Generation still exceeds Project Capability in any hour, Project Generation for each Purchaser scheduling Project Generation in such hour will be reduced on a pro rata basis based on the respective Percentage Shares. (£) Schedule Modifications. In the event that a Purchaser experiences a Forced Outage on its own system, the Purchaser shall have the following rights and obligations: Page 9 (i) The Purchaser, subject to the limitations of the Basic Agreements, shall have the right to notify the Dispatcher and schedule on an immediate basis an amount of Project Generation for its use different than its schedule in effect for the week. Such revisions can be either upward or downward. (ii) Within four hours of such notification, the Purchaser shall submit to the Dispatcher a revised schedule of Project Generation for its use for the remaining portion of the week. If such revision is not submitted, the Dispatcher will operate the Project ina manner consistent with the schedule already in effect for that week. (iii) The right of the Purchaser to schedule Project Generation up to its Percentage Share of Project Capability shall not be limited by other Purchasers scheduling Project Generation in an amount greater than their Percentage Share of Project Capability. (iv) Nothing in this section shall allow a Purchaser to schedule more Project Generation than is allowed pursuant to Section 5(a). (g) Schedules Above Participant’s Share. (i) A Purchaser, upon obtaining permission from another Purchaser that is not scheduling all of its Participant Share of Project Capability, may schedule its Net Allocation or Revised Project Allocation by using Project Capability of such other Purchaser. The - BRADLEY LAKE ALLOCATION AND SCHEDULING PROCEDURES Page 10 November 19, 1991 scheduling by a Purchaser of another Purchaser’s Project Capability shall include all the benefits, rights and obligations related to such schedule as provided in this Section. (ii) The scheduling Purchaser, as compensation for the right to schedule a portion of its Net Allocation or Revised Project Energy by use of another Purchaser’s Share of Project Capability in any hour, shall be obligated to pay such other Purchaser at $5/mW ($.005/kW) for each hour that such Purchaser’s share is used. (iii) The Dispatcher shall establish an account for each Purchaser in which the debits and credits (in Dollars) for use of a Purchaser’s Share of Project Capability under Section 5(b) will be accounted. As soon as reasonably practicable after the close of each Fiscal Year (as defined in the Power Sales Agreement), the Dispatcher shall determine the amounts which each Purchaser owes or is entitled to be paid as of the end of such Fiscal Year. Using the amounts so determined, the Dispatcher shall submit a schedule of payments to the affected Purchasers which will reduce the amounts credited or debited to each Purchaser to zero at the end of such Fiscal Year. Payments under such schedule shall be made by the owing Purchaser to the indicated Purchaser(s) within 30 days after receipt of the schedule of payments. (h) Scheduling During Periods of Pending Spill. (i) Whenever the reservoir level reaches an elevation of 1,175 feet, the Authority shall notify each Purchaser that the Reservoir has the potential of spilling water unless additional energy is scheduled by the Purchasers. (ii) The Authority shall develop a methodology for declaring and terminating periods of pending spill, which is agreed upon to the PMC in accordance with its procedures. (iii) Whenever the Authority declares that the Project is in pending spill condition, the Purchasers, to the extent system reliability and operating conditions allow, shall use their best efforts to reduce system generation to allow the Dispatcher to schedule the Project at its full available capability. - BRADLEY LAKE ALLOCATION AND SCHEDULING PROCEDURES November 19, 1991 The energy realized during periods of pending or immediate spill shall be allocated, to each Purchaser based upon its Purchaser’s Share. If a Purchaser is unable to schedule its full Purchaser’s Share of Project Capability, the energy which is not scheduled shall be made available to the other remaining Purchasers for scheduling pro rata based on their Purchaser’s Share. (iv) Once a pending spill period is suspended by the Authority, the energy scheduled and generated from inflows in excess of forecast inflows under this subsection shall be added to each Purchaser’s Net Allocation or Revised Project Energy for the month. Schedules of energy by a Purchaser during the pending spill period shall then be credited against the resulting Revised Project Energy total for each Purchaser for such month. Section 6. Project Operation. The Project shall be operated by the Dispatcher pursuant to the terms and conditions of the Dispatch Agreement and consistent with those set forth in Exhibits B, C, and D. Section 7. Project Spill. The Purchasers recognize that from time to time water from the Project Reservoir may be spilled which does not result in Project Generation. If this occurs, then: (a) The Authority shall measure the quantity of Project Spill and convert the amount of spill over and above the amount of the Bradley Minimum Flow Releases to energy, utilizing the appropriate conversion factors, and (b) Each Purchaser with a Net Allocation greater than zero during a spill period shall have its Net Allocation as adjusted in Section 5(g) reduced pro rata based upon each such Purchaser’s Net Allocation, such that the total reduction for all Purchasers is equal to the amount of energy in the Project Spill. Section 8. Losses. (a) General. The losses provided for in this Section 8 shall be accounted for in kind by reducing the amount of energy delivered to each Purchaser and not by direct monetary compensation. Page 11 - BRADLEY LAKE ALLOCATION AND SCHEDULING PROCEDURES November 19, 1991 (b) Losses on Project Transmission. Losses on the transmission lines of the Project shall be determined pursuant to load flow studies. (c) Losses _on the HEA System. Losses on the HEA transmission system under various operating conditions shall be determined by the PMC in accordance with load flow studies. The studies shall be performed with and without the Project, and a matrix of loss factors developed for various Projects, HEA load levels and transmission system operating conditions. The loss factor matrix shall be of a form and format suitable for hourly accounting of losses. If actual operating and dispatch experience indicates that the loss factors may need adjustment, further studies under the above conditions shall be done, taking into account any adjustments that experience may dictate. (i) The Dispatcher shall maintain records adequate to determine the relevant HEA load levels and transmission conditions when particular deliveries of Project power are accomplished. Such records shall be made available to the parties in the HEA Transmission Sharing Agreement upon reasonable request. (ii) Deliveries under the HEA Transmission Sharing Agreement shall be reduced for line losses as appropriate under the matrix of line losses developed under this subsection. (d) Losses on the Chugach Electric System. Deliveries by the Chugach Electric System over its transmission facilities may be accomplished by Direct Transmission (as defined in the Chugach Services Agreement) or through Offsetting Flows (as defined in the Chugach Services Agreement). (i) The Dispatcher shall maintain records adequate to determine the extent to which particular deliveries are accomplished in whole or in part by each of these means. Such records shall be made available to the Wheeling Utilities (as defined in the Chugach Services Agreement) upon reasonable request. (ii) If and to the extent deliveries are accomplished by Direct Transmission, such deliveries shall be reduced for line losses. The reduction shall be by a percentage equal to the average percentage line losses on Chugach’s wholesale system, such wholesale system line losses to be determined in Chugach’s Page 12 - BRADLEY LAKE ALLOCATION AND SCHEDULING PROCEDURES November 19, 1991 periodic rate adjustment proceedings or (in the absence of such a proceeding) through reasonable line loss studies prepared by Chugach not less frequently than once every two years; provided, that if, after a reasonable period of experience in actual operation under the Services Agreement, Chugach’s system line loss studies prepared for use in Chugach’s periodic wholesale and/or retail rate adjustment proceedings demonstrate that Chugach’s wholesale system line losses have increased as the direct result of Bradley Lake Energy (as defined in the Chugach Services Agreement) delivered by Direct Transmission, then deliveries of such energy through Direct Transmission shall thereafter be further reduced for line losses to the extent of the increase in Chugach wholesale system line losses attributable thereto. (iii) If and to the extent deliveries are accomplished through Offsetting Flows as defined in the Chugach Services Agreement, such deliveries shall not be reduced for line losses; provided, that if, after a reasonable period of experience in actual operation under the Services Agreement, Chugach’s system line loss studies prepared for use in Chugach’s periodic wholesale and/or retail rate adjustment proceedings demonstrate that Chugach’s wholesale system line losses have increased as the direct result of Bradley Lake Energy delivered through Offsetting Flows, then deliveries of such energy through Offsetting Flows shall thereafter be reduced for line losses, but only to the extent of the increase in Chugach wholesale system line losses attributable thereto. Section 9. Spinning Reserves. The Operation and Dispatch Committee shall recommend to the PMC a method for allocation of Spinning Reserves in each hour under various system operating conditions. Once approved by the PMC such Spinning Reserves shall be made available in accordance with such method as follows: (a) Spinning Reserves shall be allocated to each Purchaser on a pro rata basis based on its Percentage Share of Project Capability net of any Project Generation scheduled by the Purchaser. (b) Any additional Spinning Reserves that can be made and are available at the Project in addition to Spinning Reserves normally available in any hour as a result of operating other resources shall be allocated on a pro rata Page 13 - BRADLEY LAKE ALLOCATION AND SCHEDULING PROCEDURES November 19, 1991 basis to each Purchaser in proportion to that Purchaser’s contribution of such other resources. Section 10. Amendment or Replacement of Procedures. Upon the request of any Purchaser or the AEA, the Operation and Dispatch Committee shall review any proposal to amend or replace these Procedures at the Committee’s next meeting and make a recommendation regarding such proposal to the PMC as soon as practicable thereafter. It is the intent of the PMC that the Operation and Dispatch Committee monitor the application of these Procedures and periodically recommend changes which improve overall administration of Project operations to provide additional flexibility to the Purchasers, and reduce, where practicable, the obligation of the Authority to provide information or revised data which is not useful to the Parties.

This authority is delegated to the Power Dispatchers in order that they may perform their assigned duties and responsibilities. a. This section is not to be interpreted so as to restrict any qualified personnel from performing switching to de-energize lines or equipment; where in his or her best judgement, life, limb, or property are in danger. In emergencies qualified field personnel may immediately de-energize circuits if requested by a Fire Department, Law Enforcement Officer, or other elected or appointed public officials and perform such switching that, in his/her opinion, is required. At that time, the Power Dispatcher shall be notified to verify that all possible sources of feed have been removed. The circuits shall not be re-energized until information is received that the emergency is over and the Power Dispatcher is notified. If such switchin i been requested by a public official, the name, address and official position of the person requesting such switching shall be given to the Power Dispatcher by the individual performing switching, in writing as soon as is practical. All switching orders shall be written by the Power Dispatcher. All switching orders should be reviewed either by the Manager of Power Control, the Power Control Assistant or another Power Dispatcher. Switching orders shall be clear and concise. Each step shall begin on a new line. Each switch shall be designated by its assigned dispatching number, approximate location and type. Switching orders shall be written such that when equipment or lines are to be disconnected from any source of electric energy for the protection of personnel, the switches; circuit breakers; or other devices designated and designed for operation under the load involved at the sectionalizing point, shall be opened or disconnected first. In the direction and performance of switching, the following procedures and conventions shall be followed: a. The switchperson shall review and make sure he understands the switching order before starting the switching. IT1614(2) The switchperson shall perform all steps in the same sequence as_given in the switching order unless changes are expressly approved by the Power Dispatcher. The switchperson should carry a copy of the switching order at all times and shall check off each step as completed. The switchperson shall have access to a CEA radio at all times to facilitate contact with the Power Dispatcher. If, while executing a switching order, the switchperson has reason to believe that any further switching would be improper, he shall, AT THAT POINT report to the Power Dispatcher. If, when executing a switching order, a switch is found to be in a position other than that specified in the order, no further switching shall be completed until the Power Dispatcher approves continuation of the switching order. Each person receiving an oral message concerning the switching of lines and equipment shall immediately repeat it back to the sender and obtain the identity of the sender. Each person sending such an oral message shall require it to be repeated back by the receiver and secure the latter's identity. When it is necessary to pen a switch (air break, gas, oil, or vacuum type; including pad mounted switch cabinets) rated at 750 volts or more, the following procedure shall be requested Ls the Power Dispatcher and Performed by the switchperson. pon completion, the switchperson shall give the Power Dispatcher verbal confirmation that each appropriate step has been performed. 1.

Clearances, General 1. 1T1614(4) The Power Control Center shall be the source of authority for all electrical red clearances on the Chugach system. The Manager of Power Control may delegate authority to qualified persons to issue red clearances on their own authority. This authority is delegated to the Power Dispatchers in order that they may perform their assigned duties and responsibilities. a. The permission of the Power Dispatcher is required before anyone may work on or in close proximity to electrical parts of the Chugach system, rated 750 volts or more. b. The Power Dispatcher shall be notified as soon as such work ceases. C This section is not to be interpreted so as to restrict any qualified personnel from making repairs on or about equipment or lines on the Chugach system; where in his or her best judgement, life, limb, or roperty are in danger and communications with the Power ispatcher are made difficult by storms or other causes and the qualified person can clear the trouble promptly with available help in compliance with the remaining rules. All workmen shall be protected by a red clearance whenever they touch or work within the minimum work distance (as specified by the National Electrical Safety Code) of electrical parts (power circuits, rated 750 volts or more) which may be energized by closing an isolating device. This section is not to be construed so as to prevent the performance of "hotwork" on energized lines and equipment, without a red clearance, so long as such work is performed in accordance with the National Electrical Safety Code and the Power Dispatcher has been notified that such work will be in progress. a. The Red Clearance is a formal agreement between the Power Dispatcher and the individual in charge that the former will not authorize the re-energizing of specific lines or equipment from the power system without the latter's release of his clearance. With the issuance of a red clearance the Power Dispatcher give the assurance that: a. The equipment or lines are separated from the power system with isolating devices. b. All isolating devices have been tagged properly and wherever possible locked in the open position. Cs Available ground switches have been closed unless the holder of the clearance requests that they be left open. The Power Dispatcher will check with all other personnel holding clearances on the facility for their concurrence before opening grounding switches. d. Where possible, all remotely operated devices have been placed in local control. 4.B. e. None of the isolating devices will be ordered closed until after the red clearance has been released. In the construction of new facilities for which no isolating devices are in position to provide connection to either lines or buses of the power system, no red clearance shall be required or issued for men to work o building the facilities. It shall be the responsibility of the Chugach Inspector to see that no isolating devices (removable links or jumpers) are placed in position prematurely and if found to be so positioned to see that they are removed immediately. This section is not to be construed to prevent the energization of new construction in small blocks, as the construction is completed, provided such energization is performed in accordance with the remaining rules. In the event that one or more of the clearance points defining a Red clearance are to be retired or relocated, during construction, the existing clearance shall be released and all tags removed prior to retirement. In the event that a clearance is still required a new Red Clearance shall be issued and defined by the appropriate remaining clearance points. A red clearance shall be required regardless of the stage of the construction if the isolating device is a switch which could energize electrical parts at 750 volts and above. Ill. | Application Procedures for Receiving and Releasing Clearances I. 1T1614(5) Application for Red Clearance a. Application for red clearances should be made to the Power Dispatcher 72 hours in advance of the time set for work to begin and shall be made a minimum of 24 hours in advance of the time set for work to begin.

The individual in charge upon completion of the work and after assuring that all men and equipment are in the clear should remove all working grounds and shall report to the Power Dispatcher that he is releasing his clearance, specified by number, and that all red clearance tags in his name may be removed. In the event that the individual in charge releases his red clearance without removing his working grounds he shall identify to the Power Dispatcher each location at which the line or equipment is grounded. IT1614(7) b. A clearance shall not be transferred between parties, except as provided for in III-3, C. In the event that the individual in charge who received the clearance must transfer his authority to another person; the existing clearance shall be released by its holder and all tags removed. A new clearance and clearance number shall be issued to the new individual in charge in accordance with the safety procedures outlined in this manual. cs In the event that the individual holding the clearance is unavailable, for an unacceptable period of time and all practical means of contacting the individual have been exhausted, then his immediate supervisor shall assume full responsibility for the clearance including its release. All such instances shall be fully documented by both the Power Dispatcher and the Supervisor involved. Clearances Involving Foreign Utilities Clearance on Chugach Lines or Equipment for Employees of Other Utilities. Preliminary arrangements shall be made by the power dispatcher of the foreign utility with the Chugach power dispatcher. The Chugach power dispatcher shall ascertain the nature of the work and the name of the person who will be in charge. The Chugach power dispatcher will issue clearance to the power dispatcher of the foreign utility in the same manner and in accordance with the same rules and regulations that govern clearance to Chugach employees. If the Chugach power dispatcher deems it necessary, he shall arrange to have an authorized Chugach employee on location at this time to clarify the limits of the clearance to the person in charge of the job. Clearance on Inter-Utility Times for Chugach Employees Preliminary arrangements shall be made by the Chugach power dispatcher with the power dispatcher with the power dispatcher of the foreign utility. The terminal of the foreign end shall be cleared and tagged for the Chugach power dispatcher who will then receive clearance from the power dispatcher of the foreign utility on the terminal end. The Chugach terminal shall be cleared and tagged for the Chugach employee. The Chugach ewer dispatcher may not issue a clearance in the regular manner to the Chugach employee. Clearance on Inter-Utility Ties for the Foreign Utility Employees. Preliminary arrangements shall be made by the power dispatcher of the foreign utility with the Chugach power dispatcher. The Chugach power dispatcher shall ascertain the nature of the work. The Chugach terminal shall be cleared and tagged to the power dispatcher of the foreign utility.

REMOVING TAGS No tags shall be removed and no lines or equipment energized until the clearance has been released to the power dispatcher. As soon as possible after the clearance is released, the power dispatcher shall order the removal of all tags associated with that clearance. RECORDING MODIFICATIONS The power ae shall make the required correction on the display panel and maps of all modifications reported. TV. Hot Line Orders - General pe 1T1614(8) The Power Control Center shall be the source of authority for all hot line orders on the — system. The Manager of Power Control may delegate authority to qualified persons to issue hot line orders on their own authority. This authority is delegated to the Power Dispatchers in order that they may perform their assigned duties and responsibilities. a. The permission of the Power Dispatcher is required before anyone may work on or in close proximity to electrical parts of the Chugach system, rated at 750 volts or above. b. Once a hot line order has been requested or deemed required for a specific line or piece of equipment no work shall be performed in close proximity to it until the hot line order has been issued to the individual in charge. The Power Dispatcher shall be notified as soon as such work ceases. This section is not to be interpreted so as to restrict any qualified personnel from making repairs on or about equipment or lines on the Chugach system; where in his or her best judgement, life, limb or Peery are in danger and communications with the Power ispatcher are made difficult by storms or other causes and the qualified person can clear the trouble promptly with available help in compliance with the remaining rules. The requirement for a hot line order shall be at the discretion of either the individual in charge of performing the work or the Power Dispatcher. a. The hot line order is a formal agreement between the Power Dispatcher and the individual in charge that the former will not authorize the re-energizing of specific lines or equipment from the power system without first verifying that the latter's men and equipment are all in the clear. With the issuance of a hot line order the Power Dispatcher gives assurance that all isolating devices, connecting the specified lines or equipment to the power system, and having automatic reclosing capability have been bypassed or placed in the non-reclose position and properly tagged with a hot line tag clearly indicating that the circuit is not to be reclosed without permission of the Power Dispatcher (this is to include in-line pole mounted reclosing devices as well as station reclosing devices). Vv; Application Procedures for Receiving and Releasing Hot Line Orders 1. 1T1614(9) Application for Hot Line Orders a. Application for hot line orders shall be by 1400 hours of the day preceding the day the work is scheduled to begin. Hot line orders without application will be issued on an emergency basis only. The following information is required for hot line order applications: the name of the person requesting the application; the name of the person who will be receiving the hot line order; the exact line or piece(s) of equipment which are to be covered by the hot line order; the time and date desired for the hot line order; and the reason for the hot line order. The Power Dispatcher shall arrange to have all in-line automatic reclose devices bypassed or placed in the non-reclose position and at all points of control tagged with a Chugach hot line tag clearly indicating that hot line work is in eo and the circuit is not to be reclosed without the permission of the Power Dispatcher. The Power Dispatcher shall update and tag the dispatch board to indicate the non-reclose/bypass status of all automatically reclosing devices. In the event that a hot line order will be in place for an extended period of time, the appropriate relay setting adjustments shall be made IT1614(10) to provide standard coordination with other protective devices on the circuit. Receiving a Hot Line Order a. Each person receiving an oral message concerning the switching of lines and equipment or issuance and receipt of hot line orders shall immediately repeat it back to the sender and obtain the identity of the sender. Each person sending such an oral message shall require it to be repeated back by the receiver and secure the latter's identity. At the time specified in the request for a hot line order, the individual in charge shall contact the Power Dispatcher and inform him that he is ready to receive his hot line order. The Power Dispatcher shall grant the individual in charge the hot line order specifying which isolating devices and circuits that have been placed in the non-reclose/bypassed status. No individual] shall perform work, which has been deemed to require a hot line work order, until such an order has been granted by the Power Dispatcher. Each additional individual in charge desiring the same equipment or lines to placed under a hot line order shall request and obtain his own numbered hot line order. Releasing or Transferring a Hot Line Order a. The individual in charge, upon completion of the work and after assuring that all men and equipment are in the clear and shall report to the Power Dispatcher that he is releasing his hot line order, specified by number, and that all hot line tags in his name may be removed.

Mw nbihaw PROPOSED MOTION FOR CONSIDERATION e BY THE BRADLEY LAKE PMC Now that we are in the commercial operation phase of the Bradley Lake Project, the PMC could be better served by the various subcommittees if their recommendations for PMC action are accompanied by risk/benefit analyses of the overall effect the proposed action is expected to have. Prudent utility practice is the standard to which PMC actions are held--over emphasis on any single aspect of an issue needs to be avoided. The risk/benefit analysis is an effective way for the PMC to become aware of those factors a subcommittee considered in arriving at a particular recommendation--as well as those it did not. We request your support for the following proposed motion, believing it to be a necessary refinement of our very successful PMC management process as it transitions to commercial operations management. Proposed Motion by ML&P: Move that, "To better serve the needs of the PMC during commercial operation of the Project, a risk/benefit analysis will normally accompany any subcommittee’s recommendation for action by the PMC. The intent of this requirement is to more readily identify the pros and cons of a recommended action as it relates to prudent utility practice." NOV. 19, 1991 RECORD VOPY FILE NO Lato CHUGACH ELECTRIC ASSOCIATION, INC. estat Anchorage, Alaska Uv November 18, 1991 TO: Bradley Lake Project Management Committee min FROM: David W. Burlingame, Technical Coordinating Subcommittee Represent SUBJECT: October TCS Meeting The following is a synopsis of the October 31, 1991 TCS meeting: The primary issue of business for the TCS during the October meeting was the adoption of the Bradley Lake/Kenai Operating Guidelines. The adoption does not mean the criteria and guidelines are final, only that they are to be used by the O&D Subcommittee until any other guidelines are adopted. The guidelines were adopted by unanimous vote. HEA was represented by a non-voting member who also supported the guidelines. The Subcommittee unanimously approved the installation of unit tripping at Bradley Lake to automatically trip one unit for any line fault on the Bradley Lake transmission lines. The operating guidelines are essentially the same guidelines originally proposed by PTI utilizing the higher levels of post fault voltages. The guidelines are basically as follows: Kenai Operation - No Gas Turbines If no gas turbines are operating on the Kenai, the combination of Bradley Lake plus Cooper Lake generation should not result in more than a 7 MW export as measured at Daves Creek. Kenai Operation - One Bernice Lake Turbine If one Bernice Lake turbine is operating on the Kenai in conjunction with Bradley Lake, the combination of Kenai generation should not result in an export of more than 28-32 MW. Placing restrictions on the Bernice Lake turbine output allows Bradley Lake to operate at higher levels by approximately the same amount as the Bernice restrictions. Kenai Operation - Two Gas Turbines With two gas turbines operating at Bernice Lake, the system is only constrained by the transmission line rating. At the present time, the thermal limit of this conductor is 71 MW. The conductor is due to be replaced in January 1992 which will remove any thermal Bradley Lake Project Management Committee Page 2 October TCS Meeting restrictions. The line will then be constrained only by the voltage levels experienced along the line to Anchorage. Kenai Operation - Soldotna Gas Turbine With Soldotna No. 1 and Bradley Lake on-line, the total generation should not result in an export limit of more than 48-51 MW. If the Soldotna turbine is operated at low or restricted generation levels it will allow Bradley Lake to operate at a higher level than if one Bernice Lake turbine was on-line. However, if Soldotna is operated at higher generation levels, the Bradley output and Kenai export is considerably lower than an equivalent amount of generation located at Bernice Lake. Summary - Kenai Export Table Generators On-line Recommended Export Bradley/Cooper 7MW Bradley/Cooper & BLPP 3 or 4 28-32 MW Bradley/Cooper BLPP 3 & 4 65 MW Bradley/Cooper & Soldotna 48-51 MW The committee accepted a report prepared by PTI concerning spinning reserves located on the Kenai. The report indicates that use of spinning reserves located on Kenai gas turbines should not result in any system instabilities, but use of any Bradley Lake spinning reserves which result in the plant output being above 90 MWs may. The committee unanimously adopted a motion to limit the total scheduled amount of Bradley energy and capacity to less than 90 MW. In accepting the operating guides, the committee recognized the possibility of a fault on the Soldotna - Quartz Creek 115 kV line as being remote and did not constrain the system to values associated with this case. The committee also assumed that the stability problems associated with the Fuji exciter are not relevant at the present time due to the installation of unit tripping. Bradley Lake Project Management Committee Page 3 October TCS Meeting SVC - ABB has met with HEA, AEA and Chugach to develop preliminary control and protection schemes and to develop preliminary station layouts. ie SVC’c are expected to be operational by March 4, 1993. Bradley Lake Dispatcher Guidelines Summary - The utilities have submitted comments to SWEC on the proposed summary and are presently preparing the final report. The report should be ready for adoption by the PMC at the next meeting. State Microwave System - Due to experience to date with the reliability of the state microwave system, the TCS approved a motion to upgrade the state system by installing hot- stand-by radios on the sites which do not currently have hot-stand-by systems. The estimated cost is approximately $200,000. DWB/mel 311.DWB
