To the extent that ComEd has not dispatched the full Reserved Capacity of, the Reserved Units, Seller may sell the electric energy represented by such undispatched Reserved Capacity to third parties subject to the following requirements: (w) if such undispatched Reserved Capacity relates to a Reserved Unit which: (i) has been synchronized to the ComEd System and is delivering Electric Energy at the request of ComEd, the EO Generation Dispatcher must have released such capacity to Seller and any sales of electric energy from such capacity shall be cancellable by Seller upon not more than ten minutes notice through GCM from the EO Generation Dispatcher; or 17 (ii) is off-line at the request of the EO Generation Dispatcher, then any sales of electric energy from such capacity shall be cancellable by Seller upon not more than twenty-four hours notice through GCM from the EO Generation Dispatcher; (x) Seller shall be responsible for arranging transmission service for any deliveries of electric energy contemplated by any such sales to third parties (it being understood that this Agreement does not grant any rights of access to, or use of, any transmission service); (y) the delivery of electric energy contemplated by any such sales to third parties shall be in accordance with the provisions of the applicable Interconnection Agreement; and (z) Seller shall schedule the sale of any energy so released through EO and shall respond to any recall of such energy by EO within the applicable time period specified in Section 6(b)(i)(w). No sales of electric energy shall be made to any Person from a Reserved Unit (or any portion thereof) declared by Seller to be Unavailable. (ii) In the event that a Reserved Unit shall have electric generation capacity in excess of its Net Dependable Capacity set forth in Appendix B, Seller may offer and sell such capacity and associated electric energy to third parties on such terms as Seller shall determine in its sole discretion. Seller shall be responsible for arranging transmission service for any deliveries of electric energy contemplated by any such sales to third parties (it being understood that this Agreement does not grant any rights of access to, or use of, any transmission service); and the delivery of electric energy contemplated by any such sales shall be in accordance with the provisions of the applicable Interconnection Agreement. It is further understood that, in the event that any such sales to third parties shall be made and there shall be a derating in the associated Reserved Unit, such sales to third parties shall be curtailed in full before any curtailment of Electric Energy dispatched by ComEd from such Reserved Unit as a result of such derating. (iii) Seller may not sell Ancillary Services with respect to any undispatched Reserved Capacity referred to in Section 6(b)(i) or with respect to any excess capacity referred to in Section 6(b)(ii). 18 (c) OUTAGES (i) PLANNED OUTAGES. On or prior to the Effective Date, Seller shall submit to ComEd a proposed schedule of Planned Outages (including Planned Ratings) scheduled by Seller for the following three Contract Years for the Reserved Units and the Option Units, which schedule shall be supplemented by Seller every six months following the Effective Date by notice to the EO Generation Dispatcher to extend the period covered by such schedule by six months; PROVIDED, HOWEVER, that no Planned Outage may be scheduled to cover any portion of a Summer Period. Such schedule, and each supple ment thereto, shall indicate the planned start and completion dates for each Planned Outage shown during the period covered thereby and the amount of generating capacity that will be affected. Within sixty days of receipt of such schedule or any supplement thereto, ComEd may request reasonable modifications therein. Seller and ComEd shall work together to schedule Planned Outages to meet their mutual requirements; however, it is understood that in the event of a disagreement on such scheduling, ComEd will have the right to resolve such disagreements as it reasonably determines to be appropriate in accordance with Prudent Utility Practice. In addition, ComEd may at any time request, and Seller shall make, changes to such schedule or any such supplement if ComEd deems such changes to be necessary, PROVIDED THAT, Seller shall not be required in connection with any such changes to split a single Planned Outage into more than one outage or to reduce the duration of a Planned Outage; PROVIDED FURTHER that, except for changes requested during the first six months of the Term, such changes do not affect any Planned Outages during the six months immediately following Seller's receipt of such request; and PROVIDED FURTHER, that if Seller reasonably incurs increased costs as a result of ComEd's request to reschedule a Planned Outage, ComEd shall reimburse Seller for the actual, documented increased out-of-pocket costs. At least one week prior to any Planned Outage, Seller shall orally notify the EO Generation Dispatcher of the expected start date of such Planned Outage, the amount of generating capacity at the Reserved Units which will not be available to ComEd during such Planned Outage, and the expected comple tion date of such Planned Outage. Seller shall orally notify the EO Genera tion Dispatcher promptly of any subsequent changes in such generating capacity not available or any subsequent changes in the Planned Outage completion date. As soon as practicable, all such oral notifications shall be confirmed in writing. 19 (ii) MAINTENANCE OUTAGES. To the extent that during any Contract Year Seller needs to schedule a Maintenance Outage, Seller shall notify the EO Generation Dispatcher of such outage and shall plan such outage of generating capacity and use reasonable efforts to accommodate the requirements and service obligations of ComEd. Notice of a proposed Maintenance Outage shall include the expected start date of the outage, the amount of unavailable generating capacity of the Reserved Units and the expected completion date of the outage, and shall be given to ComEd at the time the need for the outage is determined by Seller. ComEd shall promptly respond to such notice and may request reasonable modifications in the schedule for the outage to accommodate the requirements and service obligations of ComEd. Seller shall use reasonable efforts to comply with such requested modifications and shall, if requested by ComEd, reschedule its Maintenance Outages, PROVIDED THAT it may do so in accordance with Prudent Utility Practice. Seller shall notify the EO Generation Dispatcher promptly of any subsequent changes in such generating capacity not available to ComEd or any subsequent changes in such outage completion date. As soon as practicable, any such notifications given orally shall be confirmed in writing. (iii) FORCED OUTAGES. Seller shall provide to the EO Generation Dispatcher immediately an oral report of any Forced Outage (including Forced Deratings) of the Reserved Units, which report shall include the amount of generating capacity at the Reserved Units unavailable because of such Forced Outage and the expected return date of such generating capacity, and shall update such report promptly by notice to the EO Generation Dispatcher as necessary to advise ComEd of changed circumstances. As soon as practicable, all such oral reports shall be confirmed in writing. (iv) INFORMATION RELATED TO OUTAGES. In addition to the foregoing, Seller shall provide to the EO Generation Dispatcher information relating to outages of generating capacity at the Stations which would affect Seller's ability to deliver Electric Energy from any Reserved Unit. (d) OPERATING CHARACTERISTICS. The operating characteristics of each Reserved Unit shall be consistent with the Design Limits for such Reserved Unit set forth in Appendix B unless otherwise mutually agreed by the Parties. Any changes to such operating characteristics which may affect the delivery of Electric Energy pursuant to this Agreement must be agreed by the Parties. Seller shall 20 reduce, curtail or interrupt electrical generation at the Stations in accordance with Prudent Utility Practice or take other appropriate action in accordance with the applicable provisions of the applicable Interconnection Agreement which in the reasonable judgment of ComEd may be necessary to operate, maintain and protect the ComEd System or the transmission system of another utility during an Emergency Condition or in the reasonable judgment of Seller may be necessary to operate, maintain and protect the equipment at a Station during an Emergency Condition.

(e) ANCILLARY SERVICES. There shall not be any additional charges payable by ComEd or otherwise in respect of the Ancillary Services described in Section 9. 8. TESTING Capability evaluations of the Reserved Units may be conducted by ComEd at reasonable intervals. Such evaluations shall consist of a period of one hour during which ComEd may request the Net Dependable Capacity of a Reserved Unit (as set forth in Appendix B) to generate Electric Energy for delivery to the ComEd System. Once a test period has been initiated, it must last one hour unless ComEd and the general manager at the Station in which the Reserved Unit is located mutually agree to a shorter duration. In addition, ComEd may request not more than once per Contract Year that a Reserved Unit undergo a generating test as specified in Guide No. 3A of MAIN (a copy of which is attached as Appendix D). No tests will be conducted or continued which, in the opinion of Seller, should not be conducted or continued in accordance with Prudent Utility Practice. If Seller prevents or discontinues a test in accordance with Prudent Utility Practice, ComEd shall have the right to 25 retest the affected Reserved Unit upon prior notice to Seller. Seller shall have the right to retest any Reserved Unit after the failure of any test performed at the request of ComEd pursuant to this Section 8. 9. ANCILLARY SERVICES. As directed by ComEd, Seller shall provide the following additional services (the "ANCILLARY SERVICES") with respect to the Reserved Capacity of the Reserved Units (subject to any sale(s) of electric energy made by Seller to third parties to the extent permitted under Section 6(b)(i) or (ii)): (a) Reactive supply and voltage control from generation sources (b) Regulation and frequency response (c) Operating reserve - spinning (d) Operating reserve - supplemental The requirements of these services shall be as stated in ComEd's Open Access Transmission Tariff as filed with FERC, and any other Requirements of Law and any requirements of MAIN, NERC, any ISO and any successors to the functions thereof. 10. LIMITATION OF LIABILITY In no event or under any circumstances shall either Party (including such Party's affiliates and such Party's and such affiliates' respective directors, officers, employees and agents) be liable to the other Party (including such Party's affiliates and such Party's and such affiliate's respective directors, officers, employees and agents) for any special, incidental, exemplary, indirect, punitive or consequential damages or damages in the nature of lost profits, whether such loss is based on contract, warranty or tort (including intentional acts, errors or omissions, negligence, indemnity, strict liability or otherwise). A Party's liability under this Agreement shall be limited to direct, actual damages, and all other damages at law or in equity are waived. Notwithstanding the foregoing provisions of this Section or any other Section hereof, if (i) ComEd dispatches the delivery of Electric Energy from a Reserved Unit in accordance with the provisions hereof (other than during a 26 ComEd Event of Default under Section 14(b)(i)) and Seller fails to provide the Electric Energy so dispatched by ComEd, or (ii) if Seller fails to declare a Reserved Unit Available at its Net Dependable Capacity (as set forth in Appendix B), and, during such failure, Seller sells or provides electric energy from the Reserved Unit to any Person other than ComEd (including Seller but excluding provision or use of electric energy by Seller solely for use at the Station in which the Reserved Unit is located), ComEd shall, in addition to any rights it has to an adjustment of payments otherwise due hereunder or to terminate this Agreement, be entitled to reimbursement by Seller for all of ComEd's out-of-pocket costs related to or resulting from such failure by Seller, including: (w) the costs to purchase and transmit electric energy in substitu tion for the subject Electric Energy to the extent such costs exceed the costs that would have been due hereunder had, in the case of a failure under clause (i) above, Seller provided the Electric Energy dispatched by ComEd, or the costs to purchase and transmit electric energy in substitution for the Net Dependable Capacity (as set forth in Appendix B) from the subject Reserved Unit to the extent such costs exceed the costs that would have been due hereunder had, in the case of a failure under clause (ii) above, Seller declared such Reserved Unit Available and ComEd had dispatched Electric Energy from such Reserved Unit in each case in an amount inclusive of the electric energy sold to such Person; (x) any and all amounts paid (whether in the form of cash pay ments, bill credits, tariff adjustments or otherwise) by ComEd to its customers pursuant to statute, tariff, order of a tribunal of competent jurisdiction or other Requirement of Law because ComEd was unable to provide electric energy to any of its customers to the extent that all or any part of such inability could reasonably have been expected to have been avoided absent such failure by Seller; (y) attorneys', consultants' and witnesses' fees incurred by ComEd in connection with a regulatory or judicial investigation or proceeding of any kind related to or resulting from an inability of ComEd to provide electric energy to any of its customers to the extent that all or any part of such inabil- 27 ity could reasonably have been expected to have been avoided absent such failure by Seller; and (z) any other amounts owed to third parties because of ComEd's inability to deliver electric energy if all or any part of such inability could reasonably have been expected to have been avoided absent such failure by Seller. In addition, if ComEd is unable to provide electric energy to any customer or third party and all or part of such inability could reasonably have been expected to have been avoided absent such failure by Seller, ComEd will suffer significant damages in addition to its out-of-pocket costs, the quantification of which is difficult to ascertain. Accordingly, if ComEd is unable to provide electric energy to any customer or third party and all or any part such inability could reasonably have been expected to have been avoided absent such failure by Seller, and, during such failure by Seller, Seller sells or provides electric energy from the subject Reserved Unit to any Person other than ComEd (including Seller but excluding provision or use of electric energy by Seller solely for use at the Station in which the Reserved Unit is located), Seller shall pay for each occurrence, in addition to the out-of-pocket costs described above, liquidated damages to ComEd in the amount of $25,000 for each megawatt of Net Dependable Capacity (as set forth in Appendix B) for the relevant Reserved Unit. 11. DISAGREEMENTS (a) ADMINISTRATIVE COMMITTEE PROCEDURE. Except to the extent otherwise provided in Section 5(d), if any disagreement arises on matters concerning this Agreement, the disagreement shall be referred to one representative of each Party, who shall attempt to timely resolve the disagreement. If such representatives can resolve the disagreement, such resolution shall be reported in writing to and shall be binding upon the Parties. If such representatives cannot resolve the disagreement within a reasonable time, or a Party fails to appoint a representative within 10 days of written notice of the existence of a disagreement, then the matter shall proceed to arbitration as provided in Section 11(b).

If pursuant to Section 11(a), the Parties are unable to resolve a disagreement arising on a matter pertaining to this Agreement, such disagreement shall be settled by arbitration in Chicago, Illinois. The arbitration shall be governed by the United States Arbitration Act (9 U.S.C.ss.1 ET SEQ.), and any award issued pursuant to such arbitration may be enforced in any court of competent 28 jurisdiction. This agreement to arbitrate and any other agreement or consent to arbitrate entered into in accordance herewith will be specifically enforceable under the prevailing arbitration law of any court having jurisdiction. Notice of demand for arbitration must be filed in writing with the other Party to this Agreement. Arbitration shall be conducted as follows: (i) Either Party may give the other Party written notice in sufficient detail of the disagreement and the specific provision of this Agreement under which the disagreement arose. The demand for arbitration must be made within a reasonable time after the disagreement has arisen. In no event may the demand for arbitration be made if the institution of legal or equitable proceedings based on such disagreement is barred by the applicable statute of limitations. Any arbitration related to this Agreement may be consolidated with any other arbitration proceedings related to this Agreement. (ii) The Parties shall attempt to agree on a person with special knowledge and expertise with respect to the matter at issue to serve as arbitrator. If the Parties cannot agree on an arbitrator within ten days, each shall then appoint one person to serve as an arbitrator and the two thus appointed shall select a third arbitrator with such special knowledge and expertise to serve as Chairman of the panel of arbitrators; and such three arbitrators shall determine all matters by majority vote; PROVIDED, HOWEVER, if the two arbitrators ap pointed by the Parties are unable to agree upon the appointment of the third arbitrator within five days after their appointment, both shall give written notice of such failure to agree to the Parties, and, if the Parties fail to agree upon the selection of such third arbitrator within five days thereafter, then either of the Parties upon written notice to the other may require appointment from, and pursuant to the rules of, the Chicago office of the American Arbitration Association for commercial arbitration. Prior to appointment, each arbitrator shall agree to conduct such arbitration in accordance with the terms of this Agreement. (iii) The Parties shall have sixty days from the appointment of the arbitrator(s) to perform discovery and present evidence and argument to the arbitrator(s). During that period, the arbitrator(s) shall be available to receive and consider all such evidence as is relevant and, within reasonable limits due to the restricted time period, to hear as much argument as is feasible, giving a fair allocation of time to each Party to the arbitration. The arbitrator(s) shall use all reasonable means to expedite discovery and to sanction noncompliance 29 with reasonable discovery requests or any discovery order. The arbitrator(s) shall not consider any evidence or argument not presented during such period and shall not extend such period except by the written consent of both Parties. At the conclusion of such period, the arbitrator(s) shall have forty-five calendar days to reach a determination. To the extent not in conflict with the procedures set forth herein, which shall govern, such arbitration shall be held in accordance with the prevailing rules of the Chicago office of the American Arbitration Association for commercial arbitration. (iv) The arbitrator(s) shall have the right only to interpret and apply the terms and conditions of this Agreement and to order any remedy allowed by this Agreement, but may not change any term or condition of this Agreement, deprive either Party of any right or remedy expressly provided hereunder, or provide any right or remedy that has been expressly excluded hereunder. (v) The arbitrator(s) shall give a written decision to the Parties stating their findings of fact and conclusions of law, and shall furnish to each Party a copy thereof signed by him (them) within five calendar days from the date of their determination. The arbitrator's(s') decision shall be final and binding upon the Parties. (vi) Each Party shall pay the cost of the arbitrator(s) with respect to those issues as to which they do not prevail, as determined by the arbitrator(s). (c) OBLIGATIONS TO PAY CHARGES AND PERFORM. If a disagreement should arise on any matter which is not resolved as provided in Section 11(a), then, pending the resolution of the disagreement by arbitration as provided in Section 11(b), Seller shall continue to operate the Reserved Units in a manner consistent with the applicable provisions of this Agreement and ComEd shall continue to pay all charges and perform all other obligations required in accordance with the applicable provi sions of this Agreement. (d) PRELIMINARY INJUNCTIVE RELIEF. Nothing in this Section 11 shall preclude, or be construed to preclude, the resort by either Party to a court of compe tent jurisdiction solely for the purposes of securing a temporary or preliminary injunction to preserve the status quo or avoid irreparable harm pending arbitration pursuant to this Section 11. 30 (e) SETTLEMENT DISCUSSIONS. The Parties agree that no statements of position or offers of settlement made in the course of the dispute process described in this Section 11 will be offered into evidence for any purpose in any litigation or arbitration between the Parties, nor will any such statements or offers of settlement be used in any manner against either Party in any such litigation or arbitration. Further, no such statements or offers of settlement shall constitute an admission or waiver of rights by either Party in connection with any such litigation or arbitration. At the request of either Party, any such statements and offers of settlement, and all copies thereof, shall be promptly returned to the Party providing the same. 12. ASSIGNMENT; TRANSFER OF STATIONS (a) ASSIGNMENT. Neither Party may assign its rights or obligations under this Agreement without the prior written consent of the other Party, which shall not be unreasonably withheld or delayed. Notwithstanding the foregoing, ComEd shall have the right to assign its rights and obligations hereunder without the consent of Seller to (i) any entity that has a net worth of at least $500 million and credit ratings for long-term secured debt from Standard & Poor's Ratings Group of BBB- or higher and from Moody's Investors Service, Inc. of Baa3 or higher or (ii) any affiliate of ComEd. For the purposes of this Section 12(a), any direct transfer or series of direct transfers (whether voluntary or by operation of law) of a majority of the outstanding voting equity interests of Seller (or any entity or entities directly or indirectly holding a majority of the outstanding voting equity interests of Seller) to any party other than an affiliate controlled by, or under common control with, Seller shall be deemed an assignment of this Agreement. (b) COLLATERAL ASSIGNMENT. Notwithstanding the above, ComEd hereby consents to the assignment by Seller of a security interest in this Agreement to any Lenders; PROVIDED THAT Owner shall have provided notice of any such assignment to ComEd. ComEd further agrees to execute documentation to evidence such consent, PROVIDED it shall have no obligation to waive any of its rights under this Agreement. ComEd recognizes that such consent may grant certain rights to such Lenders, which shall be fully developed and described in the consent documents, including (i) this Agreement shall not be amended in any material respect or termi nated (except for termination pursuant to the terms of this Agreement) without the consent of Lenders, which consent as to amendments shall not be unreasonably withheld or delayed, (ii) Lenders shall be given notice of, and a reasonable time period (but in no event more than the time period provided to Seller) to cure, any Seller breach or default of this Agreement, (iii) if a Lender forecloses, takes a deed in 31 lieu or otherwise exercises its remedies pursuant to any security documents, that ComEd shall, at Lender's request, continue to perform all of its obligations hereunder, and Lender or its nominee may perform in the place of Seller, and may assign this Agreement to another party in place of Seller (PROVIDED either (i) such proposed assignee is creditworthy and possesses experience and skill in the operation of electric generation plants or (ii) ComEd consents to the assignment to such proposed as signee, which consent shall not be unreasonably withheld (it being understood that ComEd may, in deciding whether to grant such consent, take into account the creditworthiness and the electric generation plant experience and skill of the proposed assignee)), and enforce all of Seller's rights hereunder, (iv) that Lender(s) shall have no liability under this Agreement except during the period of such Lender(s)' ownership and/or operation of a Station(s), (v) that ComEd shall accept performance in accordance with this Agreement by Lender(s) or its (their) nominee, (vi) that ComEd shall make all payments to an account designated by Lender(s), and (vii) that ComEd shall make representations and warranties to Lender(s) as Lender(s) may reasonably request with regard to (A) ComEd's corporate existence, (B) ComEd's corporate authority to execute, deliver, and perform this Agreement, (C) the binding nature of this Agreement on ComEd, (D) receipt of regulatory approvals by ComEd with respect to its performance under this Agreement, and (E) whether any defaults by Owner are known by ComEd then to exist under this Agreement. (c) TRANSFER OF STATIONS DURING THE TERM. Prior to the Termination Date, Seller shall not sell or otherwise transfer any interest in any Station to any Person without first obtaining ComEd's written consent, which consent shall not be unreasonably withheld or delayed and may be conditioned upon the transferee's assumption of the obligations of Seller under this Agreement in respect of such Station. No such assignment shall relieve Seller from its obligations hereunder, unless otherwise agreed to by ComEd in writing. Any such sale or transfer without consent under this Section 12 shall be null and void. 13. CALL OPTIONS Subject to the notice and other requirements contained in this Section 13, ComEd shall have the right with respect to each Contract Year to reserve some or all of the generating capacity represented by the Option Units for such Contract Year (such reservation rights being referred to herein collectively as the "CALL OPTIONS" and individually as a "CALL OPTION").

(d) EXTENDED OUTAGE. ComEd may terminate this Agreement as to a Station upon thirty days prior written notice to Seller if an outage (including an outage caused by, or resulting from, a Force Majeure Event) at such Reserved Unit(s) prevents Seller from substantially performing its obligations hereunder in respect of such Reserved Unit(s) for a consecutive period of 120 days, PROVIDED that if Seller 34 demonstrates that it has taken significant steps toward remediating the circumstances which led to such outage and certifies in writing to ComEd that such outage will end within 300 days of its commencement (and such outage in fact ends within such 300 days), then ComEd may not so terminate this Agreement. 15. FORCE MAJEURE (a) FORCE MAJEURE EVENT. For the purposes of this Agreement, "FORCE MAJEURE EVENT" means any unforeseeable event, condition or circumstance beyond the reasonable control of the Party affected (the "AFFECTED PARTY") which, despite all reasonable efforts of the Affected Party to prevent it or mitigate its effects, prevents the performance by such Affected Party of its obligations hereunder. Subject to the foregoing, "Force Majeure Event" shall include: (i) explosion and fire (in either case to the extent not attributable to the negligence of the Affected Party); (ii) flood, earthquake, storm, or other natural calamity or act of God; (iii) strike or other labor dispute; (iv) war, insurrection or riot; (v) acts of, or failure to act by, legislative, judicial or regulatory agencies or officials (collectively, "GOVERNMENTAL ACTION"); and (vi) Change of Law. (b) OBLIGATIONS UNDER FORCE MAJEURE. (i) If the Affected Party is rendered unable, wholly or in part, by a Force Majeure Event, to carry out some or all of its obligations under this Agreement, then, during the continuance of such inability, the obligation of such Party to perform the obligations so affected shall be suspended. (ii) The Affected Party shall give written notice of such Force Majeure Event to the other Party as soon as practicable after such event 35 occurs, which notice shall include information with respect to the nature, cause and date of commencement of the occurrence(s), and the anticipated scope and duration of the delay. Upon the conclusion of the Force Majeure Event, the Affected Party shall, with all reasonable dispatch, take all steps reasonably necessary to resume the obligation(s) previously suspended. (iii) Notwithstanding the foregoing, an Affected Party shall not be excused under this Section 15(b) for (x) any non-performance of its obliga tions under this Agreement having a greater scope or longer period than is justified by the Force Majeure Event or (y) the performance of obligations that arose prior to the Force Majeure Event. Nothing contained herein shall be construed as requiring an Affected Party to settle any strike, lockout or other labor dispute in which it may be involved. (c) CONTINUED PAYMENT OBLIGATION. A Party's obligation to make payments already owing pursuant to this Agreement shall not be suspended by a Force Majeure Event. (d) AVAILABILITY. Notwithstanding this Section 15, outages or deratings of Reserved Units caused by, or attributable to, Force Majeure Events shall be considered periods that the affected capacity is Unavailable unless such Force Majeure Event is an event described in clause (ii) or (iv) of Section 15(a) (in which case, such affected capacity shall be considered Available at 75% of the Net Depend able Capacity (as set forth in Appendix B) of the affected Reserved Unit(s) for the duration of such Force Majeure Event during a Summer Month and at 65% of such Net Dependable Capacity for the duration of such Force Majeure Event during a Non- Summer Month). 16.

C-2 Coal Stations Power Purchase Agreement Appendices ------------------------------------------------------------------------------- APPENDIX D MAIN GUIDE NUMBER 3A MAIN GUIDE NO. 3A (Formerly Guide No. 3) (Revision No. 3) June 8, 1995 APPROVED NOVEMBER 9, 1995 PROCEDURE FOR THE UNIFORM RATING OF GENERATING EQUIPMENT -------------------------------------------- The Mid-America Interconnected Network, Inc. bylaws provide for the coordination of planning, construction and utilization of generation and transmission facilities on a regional basis for reliability of electric bulk power supply. This MAIN Guide presents the criteria for uniform rating of generating equipment on the systems of MAIN members. XXV. GENERAL Generating capability to meet the system load and provide the required amount of reserves is necessary to assure the maximum degree of service reliability. This generating capability must be accounted for in a uniform manner which assures the use of consistently attainable values for planning and operating the system. Procedures are herein established for rating generating units in service or which will be brought into service in the future. These procedures define the framework under which the ratings are to be established while recognizing the necessity of exercising judgement in their determination. The tests required are functional and do not require special instrumentation. They are designed to demonstrate that the ratings can be obtained for the time periods required under normal operating conditions for the equipment being tested. It is intended that the terms defined and the ratings established pursuant to this MAIN Guide shall be used for all MAIN purposes, including determining generation reserves for both planning and operating purposes, scheduling maintenance, and preparation of reports or other information for industry organizations, news media, and governmental agencies. D-1 Coal Stations Power Purchase Agreement Appendices ------------------------------------------------------------------------------- XXVI. UNIFORM RATINGS Each MAIN member shall establish Monthly Net Capability ratings for each generating unit and station on the member's system. The Monthly Net Capability is the net power output which can be obtained for the period specified on a monthly adjusted basis with all equipment in service under average conditions of operation and with equipment in an average state of maintenance. The Monthly Net Capability should include generating capability which is temporarily out of service for maintenance or repair. The monthly adjustments required to develop Monthly Net Capability are intended to include such seasonal variations as ambient temperature, condensing water temperature and availability, fuels, steam heating loads, reservoir levels, and scheduled reservoir discharge. Generating capability shall be tested annually to demonstrate and verify that the Monthly Net Capability can be achieved in the month of the test. It is intended that frequent changes in Monthly Net Capability be avoided. The reported capability is, therefore, a figure which should not be altered until the accumulated evidence of tests and analyses or operating experience indicate that a long-term change has taken place. The Monthly Net Capability shall be confirmed annually and revised at other times when necessary. Confirmations and revisions will be submitted to the MAIN Coordination Center. XXVIII. GENERAL GUIDES FOR ESTABLISHING CAPABILITY RATINGS The following general guides shall be applied in establishing Monthly Net Capability: A. The total Monthly Net Capability rating shall be that available regularly to satisfy the daily load patterns of the member and shall be available for four continuous hours or more. The rating established must not require a period of operation at a reduced level during a system's remainder of the peak period to recover the Monthly Net Capability. B. The Monthly Net Capability will be determined separately for each generating unit in a power plant where the input to the prime mover of the unit is independent of the others. The Monthly Net Capability will be determined as a group for commonheader steam plants or multiple- D-2 Coal Stations Power Purchase Agreement Appendices ------------------------------------------------------------------------------- unit hydro plants and each unit assigned a rating by apportioning the combined capability among the units. C. Monthly Net Capability, as reported, will not be reduced to provide regulating margin or spinning reserve. It will reflect operation at the power factor level at which the generating equipment is normally expected to be operated over the daily peak load period. It will exclude the temporary higher output attainable immediately after a new unit goes into service or immediately after an overhaul. D. Extended capability of a unit or plant obtained through bypassing of feedwater heaters, by utilizing other than normal steam conditions, or by abnormal operation of auxiliaries in steam plants; or by abnormal utilization of reservoir storage in hydro plants; or by abnormal operation of combustion turbines or diesel units; may be included in the Monthly Net Capability if the following conditions are met: 1. The extended capability based on such conditions will be available for a period of not less than four continuous hours when needed and meets the restrictions of Section III-A. 2. Normal procedures have been established so that this capability will be made available promptly when requested by the dispatcher. E. The Monthly Net Capability established for nuclear units will be determined taking into consideration the fuel management program and any restrictions imposed by governmental agencies. F. The Monthly Net Capability established for hydro-electric plants, including pumped-hydro, will be determined taking into consideration the reservoir storage program and any restrictions imposed by governmental agencies and will be based on median hydro conditions. XXVIII. TESTING PROCEDURES TO DEMONSTRATE CAPABILITY A. General Procedure for Testing 1. Ratings will be confirmed annually or more frequently if appropriate to demonstrate the Monthly Net Capability. IF ADEQUATE DATA D-3 Coal Stations Power Purchase Agreement Appendices ------------------------------------------------------------------------------- ARE AVAILABLE TO DEMONSTRATE THE CAPABILITY DURING NORMAL PEAK LOAD PERIOD OPERATION, NO SPECIAL TEST IS REQUIRED. Peaking units and cold reserve units which are not operated frequently shall be tested at such intervals as necessary to assure that capability is available to meet operating reserve requirements. 2. If the total capability of a plant is materially affected by the interaction of its parts, a test of the entire plant will be performed to demonstrate Monthly Net Capability. 3. All equipment when tested will be in normal operating condition with all auxiliary equipment needed for normal operation in service and with provision for extended capability if this capability is to be included in Monthly Net Capability. Energy consumption by auxiliary facilities common to the entire plant (for example, coal-handling or lighting) will be distributed over the appropriate units in the plant, and will represent the consumption normally experienced during the high-load period of the day. 4. It is intended that the test loadings should be maintained at a constant level. The reported test results will be no greater than the MWh/hr integrated output for the test period. B.

REPORTING PROCEDURES Each member shall submit the required data on the included Uniform Rating Forms to the MAIN Coordination Center annually on or before November 1 for the following calendar year. Each annual report shall cover all existing units, planned start-up of new units, and planned retirements of units and shall consist of the following: D-5 Coal Stations Power Purchase Agreement Appendices ------------------------------------------------------------------------------- 1. A letter identifying those units whose rating has not changed, showing the dates of latest tests confirming capabilities. 2. Completely revised forms (Form A and B-1, B-2, or B-3) for units on which a change has occurred. 3. Completely revised form (Form A) showing planned additions or retirements beginning with the month of commercial operation or month of retirement. Between annual reporting, revised forms shall be submitted as necessary for new units placed in commercial operation, units retired, and for units where tests show the rating has changed. Any change in additions, retirements, or ratings shall be submitted within 30 days of the addition, retirement, or test. In this manner, by each November 1, all test data should be current. However, the letter should be submitted confirming the dates of tests. The MAIN Coordination Center will analyze and review the annual reporting for completeness and correctness and report the need for clarification to the member concerned. The MAIN Coordination Center will maintain the updated set of reports, including current changes as they occur, from the MAIN members, and will provide complete reports and/or revisions to the members requesting them. A. Uniform Rating Form A This form is used to report the Monthly Net Capability of each unit in each station. Where required by the number of units in a station, additional sheets should be used. B. Uniform Rating Forms B-1, B-2, and B-3 These forms are used to report test results, certain actual and five year average variables where pertinent, and to show relationship of actual net generation to stated capability during the month of the test. It is the intent that test data equal or exceed stated Monthly Net Capability to demonstrate that this level of generation can be achieved. Where simultaneous tests of several units are conducted, as in common steam header plants, data should be reported for each unit and total of the group.

F-9 Coal Stations Power Purchase Agreement Appendices -------------------------------------------------------------------------------- APPENDIX G REGULATING PERFORMANCE VALUE METHODOLOGY REGULATING PERFORMANCE VALUE by Howard F. Illian, Bulk Power Operations, and Ray W. Rathsam, VISTA, December 11, 1995 The maneuverability of Commonwealth Edison generating units is measured by a method called REGULATING PERFORMANCE VALUE, RPVP. RPVp is designed to effectively measure the relative contribution of each generating unit to the total system regulation. For the first time regulation will be viewed not as control provided to follow a system disturbance, but rather as control to follow repetitive system disturbances. These repetitive disturbances are considered to result in a sinusoidal signal that the control system is required to follow. As a result, the control requested from each generating unit can also be represented as a sinusoidal signal. A unit providing system control under the direction of the Economic Generation Control (EGC) system will move up and down to the control pulses sent to the unit by the EMS computer. That sinusoidal movement can be described by a frequency component, Period, and a peak to peak Amplitude. This is shown in Figure 1. [GRAPHIC] For a given Period the greater the Amplitude that a unit can follow, the greater the unit's contribution to total system control. Therefore, representing the ability of each unit on the system to follow a simple sine wave with a single number will accurately represent G-1 Coal Stations Power Purchase Agreement Appendices -------------------------------------------------------------------------------- the relative ability of that unit to contribute to the control of the CECo system. This is what RPVp attempts to measure. The EMS computer is currently collecting data on a number of specific parameters for each generating unit while it is on EGC. Some of these measured parameters are used to calculate the RPVp value. Variable #1: ARR = Average Telemetered Dialed In Ramp Rate This variable is the telemetered, time weighted, average value of the ramp rate that is dialed into the EGC console at the generating unit control room weighted by the time the unit is actually on EGC. Variable #2: OR% = Average Observed Raise Ramp Rate Percent This variable is the percentage of the telemetered dialed in raise ramp rate that the unit actually provides while on EGC. It is limited to maximum value of 100% since the logic in the EGC system will not ramp a unit faster than the Telemetered Dialed In Ramp Rate. Variable #3: OL% = Average Observed Lower Ramp Rate Percent This variable is the percentage of the telemetered dialed in lower ramp rate that the unit actually provides while on EGC. IT is limited to maximum value of 100% since the logic in the EGC system will not ramp a unit faster than the Telemetered Dialed In Ramp Rate. Variable #4: LTR = Average Lower to Raise Turn Around Time This variable is the average amount of time it takes to turn the unit around from moving down to moving up while it is on EGC. Variable #5: RTL = Average Raise to Lower Turn Around Time This variable is the average amount of time it takes to turn the unit around from moving up to moving down while it is on EGC. Variable #6: MWR = Average Telemetered Megawatt Range This variable is the telemetered, time weighted, average of the range provided by the high and low limits dialed into the EGC console G-2 Coal Stations Power Purchase Agreement Appendices -------------------------------------------------------------------------------- at the generating unit control room weighted by the time the unit is actually on EGC. Variable #7: RPVRP = Raw Regulating Performance Value This variable represents the peak to peak amplitude that a generating unit with the above variables could provide during a ten minute period as limited by the MWR. It is calculated by weight averaging the daily raw RPV with the daily effective % time on control. K the RPVRP IS greater than the MWR, the RPVRP IS set to the value of the MWR as an upper limit. Variable #8: TC % = Percent of Time on Control This variable is the time the unit is on control as a percentage of time that it is operating and could be available for control. Variable #9: RPVP = Regulating Performance Value This is the final measure of regulating performance and represents the effective relative contribution of the generating unit to system control. Using the above variables, the value for RPVRP and RPVP are calculated using the following equations to indicate the Amplitude of control available from the unit. RPVRP = [l0-LTR -RTL][ARR /2 ][0L% + OR%] /200 (1) RPVP = RPVRP X TC% (2) In simple terms, the RPVRP and RPVp are measures of the peak to peak movement of a generating unit following a full sinusoidal wave during a ten minute period. This can be seen from Figure 2. G-3 Coal Stations Power Purchase Agreement Appendices -------------------------------------------------------------------------------- [GRAPHIC] This result is then multiplied by the percentage of time on control to give the REGULATING PERFORMANCE VALUE,RPVP. Station contributions to system regulation are derived by summing the RPVs from the generating units at the station. Division contributions to system regulation are derived by summing the R PVs from all of the stations in the division. Over the last few years a strong correlation has been shown between the total system RPV and A1/A2 control performance. During that same period it was discovered that not only is the peak to peak magnitude an appropriate measure, but that unless that sinusoid is balanced, the effective peak to peak value will be limited by the smaller of either the raise or lower portion of the sinusoid. It was also recognized that uncertainty was highly detrimental to performance. As a result the above equations have been modified to measure the smaller of the two halves and to penalize unpredictability of the response. The latest method of measuring RPVp uses the following modified variables and equations: Variable #1': SRR = Smallest Telemetered Dialed In Ramp Rate G-4 Coal Stations Power Purchase Agreement Appendices -------------------------------------------------------------------------------- This variable is the smallest telemetered value of the ramp rate that is dialed into the EGC console at the generating unit control room each hour, average weighted by the time the unit is actually on EGC. Variable #2': OR% = Average Observed Raise Ramp Rate Percent This variable is the percentage of the telemetered dialed in raise ramp rate that the unit actually provides while on EGC in response to control dispatched. It is limited to maximum value of 100% since the logic in the EGC system will not ramp a unit faster than the Telemetered Dialed In Ramp Rate. Variable #2A: DR = Portion of Time Unit is Available to be Dispatched for Raise This variable is the portion of the time that the unit actually accepts raise signals while on EGC. When multiplied by the new variable 2' It results in the same value as the old variable 2. Variable #3': OL% = Average Observed Lower Ramp Rate Percent This variable is the percentage of the telemetered dialed in lower ramp rate that the unit actually provides while on EGC in response to control dispatched. It is limited to maximum value of 100% since the toni0~c! ~ha FGC system will not ramp a unit faster than the Telelmetered Dialed In Ramp Rate. Variable #3A: D L = Portion of Time Unit is Available to be Dispatched for Lower This variable is the portion of the time that the unit actually accepts lower signals while on EGC. When multiplied by the new variable 3' It results in the same value as the old variable 3. When the above variables are substituted into the new equation, the value of RPVp is calculated with the following equations: RPVRP = MIN[(5 -LTR)(SRR)(OR%)(DR ),(5 - RTL)(SRR)(O L%)( DL, )] /100 (3) RPVP = RPVRP X TC% (4) The value of RPVRP is still limited by the value of MWR as it was previously. G-5 Coal Stations Power Purchase Agreement Appendices -------------------------------------------------------------------------------- APPENDIX H GADS CAUSE CODES H-1 C.E.Co. G.P. No. 354 Appendix E Page 1 of 16 SYSTEM POWER SUPPLY (SPS) DERATING AND OUTAGE REASON CODING SYSTEM PURPOSE - The purpose of this system is to correctly utilize planned, maintenance and unplanned deratings and to simplify the reason code data interpretation. This system follows NERC/GADS as well as INPO Guidelines. I. Unit Classifications A. Available - Unit is on line or in reserve shutdown. All events for this class will be deratings. B. Unavailable - Unit is in an outage. The major cause is given by an outage reason code. All other events during this period are classified as deratings. II. Event Designations A. Derating - Exists whenever a unit is limited to a power level less than its gross maximum capacity. The equipment causing the derating must not be the cause of a unit outage. 1. Unplanned - Designated by reason code beginning with "D". The equipment may or may not be out of service. 2. Maintenance - Designated by a reason code beginning with "M". The equipment may or may not be out of service. A maintenance derating is one which may be postponed beyond the end of the next weekend. The distinction between a maintenance derating and outage is made by determining whether or not the unit is available. 3. Planned - Designated by a reason code beginning with "S". The equipment may or may not be out of service. A planned derating is one which is planned at least four weeks in advance. The distinction between a planned derating and outage is made by determining whether or not the unit is available. C.E.Co. G.P. No. 354 Appendix E Page 2 of 16 B. Outage - Exists when a unit is not synchronized to the grid system and not in a reserve shutdown state. 1. Forced Unplanned - Designated by a reason code beginning with "0". The equipment corresponding to the reason code is the sole cause of the unit forced outage. Only one "0" code may exist at a time. B. Outage (Continued) Note: There is one exception to the above rules. For multiboiler units at Joliet 29 and Powerton, outages pertain to each boiler also. For example, if an "0" code exists, depending on the reason, it could mean that boiler 1, boiler 2, both boiler 1 and 2, or the unit is out of service. Depending on which event is occurring, more than one "0", "M" or "S" code may exist at a time. 2. Maintenance - Designated by a reason code beginning with "M". The equipment corresponding to the reason code is the sole cause of the unit maintenance outage. No "0" code may exist during this period. A maintenance outage must be able to be postponed beyond the end of the next weekend and must be completed before the next planned outage. The cause of the maintenance outage is the "M" code with the highest magnitude of derating of all other "D", "S", and "M" codes that may be simultaneously occurring. 3. Planned - Designated by a reason code beginning with "S". The equipment corresponding to the reason code is the sole cause of the planned outage. A planned outage must be scheduled at least four weeks in advance and usually lasts several weeks. Usually no other derating code exists during this period. C. Reserve Shutdown - Exists when a unit is available for service but is not synchronized due to lack of load demand. D. Non-curtailing - Designated by an "N" code except for nuclear ramp-up limitation after SPS load drop. A non-curtailing event is an event that C.E.Co. G.P. No. 354 Appendix E Page 3 of 16 exists when equipment is removed from service for maintenance, testing, or other purposes that does not result in an outage or derating on the unit.
