PURCHASE OF ENERGY 7.1 Payment of Energy shall be based on time of delivery. The time periods currently in effect are shown in Exhibit B and may be revised from time to time. 7.2 Beginning with Initial Operation and continuing for the term of this Agreement, Seller shall sell and deliver and SDG&E shall purchase and accept, Energy produced from the Generating Facility up to the Nameplate rating specified in Section 2.1.1, according to SDG&E's Energy Payment Schedule as updated from time-to-time. For out-of-service area Generating Facilities all energy purchased shall be adjusted to reflect losses from the Point of Delivery to the Designated Point of Interconnection and loses incurred in delivering energy to the Point of Delivery. Additionally, Seller shall receive no line loss adjustments or credits for line losses deemed avoided by on-system Generating Facilities. 8. METHOD OF PURCHASE AND SALE 8.1 All Energy delivered to SDG&E at the Point of Delivery and registered by the Meters located thereat shall be provided according to the option described below and selected in Section 2.3. 8.1.1 Simultaneous Purchase and Sale: Seller shall sell and deliver to SDG&E the total Generat- ing Facility output, minus Station Load, to the Point of Delivery. Seller shall purchase from SDG&E all energy used by Seller for its own consumption. 8.1.2 Sale of Surplus Energy: Seller shall sell and deliver to SDG&E at the Point of Delivery any Surplus Energy generated by the Generating Facility. Seller shall purchase from SDG&E any additional energy required for Seller's own consumption. 8.1.3 Off-System Sales: Seller shall sell to SDG&E at the Point of Delivery Energy delivered from the Generating Facility less any losses associated with such delivery of power from the Generating Facility to the Point of Delivery and from the Point of Delivery to the Designated Point of Interconnection. 8.2 All Energy delivered to SDG&E by Seller shall be metered according to time-of-use metering at Seller's expense. 8.3 Seller (except an out-of-service area Seller) shall have the ability to convert between the options specified in Section 8.1 provided that the Seller gives SDG&E a minimum of sixty (60) days advance written notice prior to the desired date of such conversion. Seller may not convert more than once in any 12 month period. Any and all costs incurred by SDG&E as a result of any such conversion shall be paid by the Seller within thirty (30) days of receipt of notice from SDG&E of the amount of such costs. In addition, the cost of SDG&E Facilities and Line Extension Facilities upon which the monthly O&M charge is based shall be adjusted to reflect the costs of such conversion. SDG&E shall not be required to remove or reserve capacity of the Interconnec- tion Facilities or Line Extension Facilities made idle by Seller' s energy sale conversion except as provided in SDG&E's Electric Department Rule 21 and may use such facilities at any time to serve other customers or to interconnect with other elec- tric power sources as provided in SDG&E's Electric Department Rule 21. 8.4 If the option described in Section 8.3 is exercised, then termination provision (as described in Section 17) shall apply to the amount by which the Firm Capacity is reduced as a result of such conversion. 8.5 SDG&E shall process a request by Seller to convert between the Options specified in Section 8.1 and institute any changes made necessary by such request as expeditiously as possible given SDG&E's other resource commitments. The conversion shall be effective on the date SDG&E notifies Seller that all changes necessary to accommodate such conversion have been completed. 9. PURCHASE OF CAPACITY 9.1 Payment for Capacity shall be based on time of delivery. The time periods currently in effect are shown in Exhibit B and may be revised from time to time. 9.2 Beginning on Initial Operation and continuing until the Scheduled Firm Capacity Operation Date or the Firm Capacity Availability Date of the Generating Facility, whichever occurs later subject to the provisions of this Agreement, Seller shall sell and deliver and SDG&E shall purchase and accept, as available capacity produced from the Generating Facility up to the Nameplate Rating of the Generating Facility specified in Section 2.1.1, according to SDG&E's As Available Capacity Payment Schedule as updated from time to time. 9.2.1 For an out-of-area Generating Facility, capacity payments to Seller shall be adjusted to reflect additional losses from the Generating Facility to the Point of Delivery and from the Point of Delivery to the Designated Point of Interconnection. Additionally, Seller shall receive no line loss adjustments or credits for any line losses deemed avoided by on-system Generating Facilities. 9.3 Beginning on the Scheduled Firm Capacity Operation Date or the Firm Capacity Availability Date of the Generating Facility, whichever occurs later subject to the provisions of this Agreement, and continuing for the remaining term of this Agreement, Seller shall provide and SDG&E shall purchase Firm Capacity from the Generating Facility to the SDG&E system at the Point of Delivery in an amount and for a period as specified in Sections 2.2.1 and 2.1.6 respectively, according to one of the following options as selected in Section 2.2.2: Option 1 - Dispatchable Option 2 - Actually Delivered 9.4 SDG&E shall purchase Firm Capacity based upon one of the following options as selected by Seller in Section 2.2.3: Option 1: The Capacity Payment Schedule for Firm Capacity Qualifying Facilities in effect at the time of execution of this Agreement attached as Exhibit C; and Option 2: The Capacity Payment Schedule for Firm Capacity Qualifying Facilities in effect as of the Scheduled Firm Capacity Operation Date of the Generating Facility. 9.5 If Seller has elected to provide SDG&E Firm Capacity according to the Dispatchable Option (Option 1), payments for Firm Capacity under this Agreement shall be calculated as follows: The monthly payment for Firm Capacity will be one-twelfth of the product of the Firm Capacity Price (CP) taken from the Firm Capacity Payment schedule in effect at the time of execution, multiplied by the Firm Capacity (FC) and the Capacity Bonus Factor (CBF). Hours of curtailment and energy deliveries during curtailments shall be specifically excluded from the capacity calculations. CP = Firm Capacity Price FC = Firm Capacity (for out-of-service area Generating Facilities, minus any adjustments for line losses from the Point of Delivery to the Designated Point of Interconnection) CBF = Capacity Bonus Factor (see 9.7) ($) = (1/12) CP x FC x CBF 9.6 If Seller has elected to provide SDG&E with the Firm Capacity according to the Actually Delivered Option (Option 2), payments for Firm Capacity under this Agreement shall be calculated as follows: The monthly payment for Firm Capacity will be the product of the Period Price Factor (PPF), the Monthly Delivered Capacity (MDC) and the Capacity Bonus Factor (CBF), plus any allowable payment for outages due to scheduled maintenance. ($) = PPF x MDC x CBF The PPF is determined by multiplying the Firm Capacity Price, taken from the Firm Capacity Payment Schedule in effect on the date of execution, by the following Al- location Factor (AF): AF(yr/month) x Firm Capacity Price($/kw-yr)=PPF($/kw-mo) Summer 0.13801 x = Winter 0.04428 x = AF = The factor that allocates the Firm Capacity Price between summer and winter months. These factors may be changed upon one year notice from SDG&E. The MDC is determined as follows: 1) Determine the Performance Factor (P), which is defined as follows: P = A (1-L) (P is less than or equal to 1) C x (B-S) x E A = Total kilowatt-hours delivered during all on-peak and semi-peak hours during the month excluding any Energy associated with generation levels greater than the Firm Capacity. L = (for an out-of-service area Seller) The losses, expressed as a decimal fraction, associated with delivery of capacity purchased by SDG&E from the Point of Delivery to the Designated Point of Interconnection as specified in the Section 2.1.2. C = Firm Capacity. B = Total on-peak and semi-peak hours during the month. S = Total on-peak and semi-peak hours during the month the Generating Facility is out of service on scheduled maintenance. E = 0.8 to reflect a 20% allowance for forced outage. (2) Determine the Monthly Capacity Factor (MCF), which is computed using the following expression: MCF = P x (1.0 - M) D M = The number of hours during the month the Generating Facility is out of service on scheduled maintenance. D = The number of hours in the month. (3) Determine the MDC by multiplying the MCF by C: MDC (kilowatts) = MCF x C The monthly payment for Firm Capacity is then determined by multiplying the proper PPF determined above by MDC and CBF. ($) = PPF x MDC x CBF CBF = Capacity Bonus Factor (See Section 9.7) 9.6.1 Furthermore, the payment for a month in which there is an outage for scheduled maintenance shall also include an amount equal to the product of the average hourly capacity payment and the number of hours of outage for scheduled maintenance in the month calculated according to the following formula: Payment = ($) x S B - S where ($) is the monthly payment from the second paragraph of Section 9.6, line 6 and B and S are from paragraph 9.6(1). 9.7 Capacity Bonus Factor. A Seller who actually delivers Firm Capacity during the on-peak hours of the peak months at a Capacity Factor of 85%, as defined by the CPUC, is entitled to an incentive payment. The Capacity Bonus Factor (CBF) will be calculated as follows: CBF = ED ( 1-L) (CBF is greater C x (PP - SP) x .85 than or equal to 1) ED = Energy delivered during on-peak hours of the peak months. L = (for an out-of-service area Seller) The losses, expressed as a decimal fraction, associated with delivery of capacity purchased by SDG&E, from the Point of Delivery to the Designated Point of Interconnection as specified in Section 2.1.2. C = Firm Capacity PP = On-peak hours in the peak months SP = Total on-peak hours during the peak months that the Generating Facility is out of service on Scheduled Maintenance. Conditions (1) Agreement must be in effect and Generating Facility must be operable for all of the peak months in order that CBF be calculated. (2) The CBF for the period October 1 to September 30 will be determined by the Generating Facility's performance in the preceding peak months. (3) CBF will be equal to 1.0 until Seller's peak months data is available. (4) During probationary periods CBF will be limited to 1.O. (5) Hours of curtailment and energy deliveries during curtailments shall be specifically excluded from the capacity calculations. 9.8 Minimum Performance Requirements: To receive capacity payments, the Generating Facility must meet the following requirements: 9.8.1 The amount of Firm Capacity shall be dispatchable by SDG&E throughout the year (Option 1) or actually delivered to SDG&E for all of the on-peak hours of the peak months (Option 2). These months are currently defined as the months of June, July, August and September, and may be changed upon one year notice by SDG&E. All Energy generated by the Generating Facility at levels greater than the amount of Firm Capacity will be specifically excluded from the Firm Capacity payment calculations. Hours of curtailment and energy deliveries during curtailments shall be specifically excluded from the capacity calculations. 9.8.2 If Seller chooses Option 1, the Firm Capacity shall be dispatchable by SDG&E throughout the year, subject to a maximum 20 percent monthly allowance for Forced Outages and scheduled maintenance, and also subject to an allowance for up to 45 days for a major overhaul. Except during the peak months on the SDG&E system, Seller may accumulate and apply the 20 percent allowance for Forced Outages for any consecutive three (3) month period. Dispatchable means that the Generating Facility is operable and is capable of delivering capacity, and, when called upon, must deliver at least the amount of capacity requested by SDG&E up to the full amount of Firm Capacity. Curtailment rights are as defined elsewhere in this Agreement. 9.8.3 If Seller chooses Option 2, the Firm Capacity must actually be delivered to SDG&E for all the on-peak hours of all the peak months, excluding scheduled maintenance and subject to a 20 percent monthly allowance for Forced Outages. 9.9 Failure to meet minimum Performance requirements. If Seller fails to meet the minimum performance requirements, on a monthly basis, then the Seller will be placed on a probationary period not to exceed 15 months, and will be subject to the following: 9.9.1 Under Option 1 (Dispatchable): During the probationary period, the Seller will continue to receive capacity payments for the amount of dispatchable capacity available during said period. During the probationary period, the Seller's monthly payment for capacity shall be determined by substituting for the Firm Capacity, the capacity at which Seller would have met the minimum performance requirements. In any month during the probationary period that Seller does not meet the minimum performance requirements at whatever capacity was determined for the previous month, Seller's monthly payment for capacity shall be determined by substituting the capacity at which Seller would have met the minimum performance requirements. If after the expiration of this period, the Seller has not demonstrated an ability to provide its amount of Firm Capacity to SDG&E, that capacity shall be derated and subsequent monthly payments limited to the new amount of capacity. The amount by which the Seller's capacity is reduced shall be subject to Section 17 of the Agreement. 9.9.2 Under Option 2 Actually Delivered: During the probationary period, the Seller shall earn capacity payments for the amount of capacity actually delivered. If the Seller fails to deliver the full contract capacity during each of the following year's peak months, the amount of Firm Capacity shall be derated to the greater of the Firm Capacity actually delivered when the minimum requirements are not met, or the amount of Firm Capacity which would be reasonably likely to be met. The amount by which the Firm Capacity is reduced shall be subject to Section 17 of the Agreement. 9.9.3Hours of curtailment and energy deliveries during curtailments shall be specifically excluded from the capacity calculations. 9.10 Scheduled Maintenance: Scheduled Maintenance for the Generating Facility shall be allowed according to the following conditions: 9.10.1 Outage periods for scheduled maintenance shall not exceed 840 hours (35 days) in any 12 month period. 9.10.2 Seller may accumulate unused scheduled maintenance hours on a year-to-year basis up to a maximum of 1,080 hours (45 days). This accrued time must be used consecutively and only for major overhauls. 9.10.3 Major overhauls shall not be scheduled during the peak months and shall be limited to once every three years. 9.10.4 Scheduled maintenance shall not exceed 30 peak hours during the peak months. 9.10.5 Seller shall notify SDG&E 24 hours prior to a scheduled outage of less than one day, one week prior to a scheduled outage of one day or more (except for major overhauls), and six months prior to a major overhaul during periods acceptable to both parties. Agreed upon dates shall not be changed without formal written notice to SDG&E in accordance with Section 2.6 of this Agreement. 9.10.6 Capacity payments will continue during allowed outages for scheduled maintenance. 9.11 Adjustment to Firm Capacity: Firm Capacity as specified in Section 2.2.1 may be adjusted only under the following conditions: 9.11.1 Seller may increase the amount of Firm Capacity with the approval of SDG&E and receive payment for the additional capacity thereafter. A new overall capacity price will be established based on the original capacity price for the original Firm Capacity and the applicable capacity price for the remaining term of this agreement published by SDG&E at the time the increase is first delivered to SDG&E. This new overall capacity price will be prorated in proportion to the original Firm Capacity and the increase in Firm Capacity. 9.11.2 Either Party may request, when it reasonably appears that the capacity of the Generating Facility may have changed for any reason, that a new Firm Capacity be determined. If a decrease occurs that decrease will be subject to Section 17 of the Agreement. 10.

METERING OF ENERGY DELIVERIES 15.1 Metering for electric service to Seller and for Energy purchases by SDG&E shall be at the Point of Delivery or as specified in the Three Party Operating Agreement. Metering will be installed which will measure and record flows in each direction. All the meters and equipment used for measuring power delivered to SDG&E shall be located on the side of the Interconnection Facilities selected by Seller and selected in Section 2.5 or as otherwise specified in the Three Party Operating Agreement. If Seller selects a metering location on Seller's side of the Interconnection Facilities the power recorded as delivered to SDG&E shall be adjusted by applying the transformer loss compensation factor specified in Section 2.5 to derive the amount of energy and capacity deemed delivered. The transformer loss compensation factor shall be as agreed to by the parties or at Seller's election, shall be calculated based on the measured value of transformer losses from the transformer to be used. If Seller chooses this latter option, Seller shall pay SDG&E for the cost of determining this measured value. 15.2 All Meters shall be sealed and the seal shall be broken only by SDG&E, upon occasions when the Meters are to be inspected, tested or adjusted. 15.3 SDG&E shall inspect and test all Meters upon their installation and on its regular testing schedule. If requested to do so by Seller, SDG&E shall inspect or test a Meter, but the expense of such inspection or test shall be paid by Seller unless the Meter is found not to comply with the accuracy specifications found in SDG&E's Electric Department Rule 18, or any superseding standard. 15.4 If a Meter is in error, Section B of SDG&E's Electric Department Rule 18, or any superseding standard, shall be applied. 15.5 Seller shall report the hourly and daily Energy recordings to SDG&E periodically as agreed upon by the Authorized Representatives. Where the Generating Facility's rated capacity is greater than 2 Mw, the Generating Facility's output shall be telemetered to SDG&E's Mission Control Center as specified in SDG&E's Electric Department Rule 21. 16. CONTINUITY OF SERVICE 16.1 SDG&E shall not be obligated to accept or pay for, and SDG&E may require Seller to temporarily curtail, interrupt or reduce deliveries of Energy upon advance notice to Seller, in order for SDG&E to construct, install, maintain, repair, replace, remove, investigate or inspect any of its equipment or any part of its system, or if SDG&E determines that such curtailment, interruption or reduction is necessary because of a System Emergency, forced outages on the SDG&E system or its interconnected tie lines, operating conditions on its system, or compliance with prudent electrical practices, provided that SDG&E shall not interrupt deliveries pursuant to this Section solely in order to take advantage, or to make purchases, of less expensive energy elsewhere. 16.2 SDG&E shall not be obligated to accept or pay for, and may require Seller, with a Qualifying Facility with Nameplate Rating of one megawatt or greater, to temporarily curtail, interrupt or reduce deliveries of Energy during periods of Minimum Load Condition where such purchase results in "negative avoided cost" to SDG&E as such term is defined by the CPUC. 16.3 Notwithstanding any other provision of this Agreement, if at any time SDG&E determines that either (a) the Generating Facility may endanger SDG&E personnel, or (b) the continued operation of the Generating Facility may endanger the integrity of SDG&E's electric system, SDG&E shall have the right upon notice to Seller, to disconnect the Generating Facility from SDG&E's system. The Generating Facility shall remain disconnected until such time as SDG&E is satisfied that the condition(s) referenced in (a) or (b) of this Section 16.3 have been corrected. 16.4 Whenever possible, SDG&E shall give Seller reasonable advance notice of its intent to refuse to purchase Energy under this Section 16. 16.5 The Parties will coordinate temporary curtailment and interruption or reduction of deliveries of Energy required for either Party to construct, install, maintain, repair, replace, remove, investigate or inspect equipment in its respective electric system. 16.6 Curtailment of out-of-service area Generating Facility 16.6.1 SDG&E may curtail deliveries of Energy from the Generating Facility , subject to the conditions set forth in this Section. 16.6.2 For purposes of this Section 16.6, each day shall be considered to begin at midnight (0001 hrs) and end at midnight (2400 hrs). 16.6.3 In the event an hour of curtailment scheduled pursuant to this Section 16.6. coincides with scheduled maintenance, such hour shall be counted as scheduled maintenance for the purposes of this Agreement. 16.6.4 SDG&E shall designate the type of curtailment as either Flexible Curtailment or Block Curtailment. SDG&E shall continue to make Firm Capacity payments for each curtailment hour subject to the provisions of this Section 16.6. At the time SDG&E gives notice of a curtailment period, SDG&E shall also provide a non-binding estimate of its expected Alternative Energy Cost during the curtailment period. Seller shall be provided a copy of SDG&E's California Power Pool Economy Energy Transactions log indicating SDG&E's system decremental value to verify the Alternative Energy Cost offers. This information is confidential to SDG&E and Seller shall not provide this information to anyone without SDG&E's written consent. 16.6.5 To schedule a Flexible Curtailment, SDG&E shall notify Seller, no later than two (2) hours prior to the start of the curtailment period, of the hours, duration, and Alternative Energy Cost for the curtailment period. No later than one-half (1/2) hour after SDG&E notifies Seller of such curtailment period, Seller shall notify SDG&E of the level at which Seller will operate during the curtailment period. If Seller fails to provide SDG&E such notice within the time required, SDG&E shall limit Seller's schedule of deliveries during the curtailment period to the level at which Seller was delivering to SDG&E at the time notice was due. The price for Energy delivered and accepted by SDG&E during these periods shall be as described in Section 16.6.8.(b). Each Flexible Curtailment period shall have a duration of no less than eight (8) consecutive hours. 16.6.6 The maximum amount of Flexible Curtailment in any calendar year shall be as follows: Flexible Maximum Contract Curtailment Number of Years Hours Curtailments 1 through 9 900 125 10 through 15 1400 125 16 thereafter 2200 150 16.6.7 Each year SDG&E shall notify Seller of SDG&E's intent to schedule a Block Curtailment within a six month time period. When SDG&E better evaluates the timing of the Block Curtailment, SDG&E shall give Seller not less than three weeks notice of the starting time, duration, and Alternative Energy Cost for the Block Curtailment. No later than seven (7) days after SDG&E notifies Seller of such curtailment period, Seller shall notify SDG&E of the level at which Seller will operate during the curtailment period. If Seller fails to provide SDG&E such notice within the time required, SDG&E shall limit Seller's schedule of deliveries during the curtailment period to the level at which Seller was delivering to SDG&E at the time notice was due. The price for Energy delivered and acc- epted by SDG&E during these periods shall be as described in Section 16.6.8.(b). The amount of Block Curtailment in any Contract Year shall not exceed one 400 hour block or two 200 hour blocks. 16.6.8 During each hour of Flexible or Block Curtailment, payments shall be made based on the following: a) Firm Capacity payments shall be made in accordance with Section 16.6.11. b) Payments for Energy which Seller has opted to continue to deliver and provided proper notice of such election in accordance with Sections 16.6.5 and 16.6.7 shall be purchased by SDG&E at the Alternative Energy Cost. c) In the event that the output of the Generating Facility during any curtailment hour exceeds the level of scheduled deliveries, pursuant to Sections 16.6.5 and 16.6.7, Seller shall not be paid by SDG&E for any Energy in excess of such scheduled amount during such curtailment hour(s). 16.6.9 Nothing in this Section 16.6 is intended to provide Seller the right, either expressed or implied, to deliver energy to SDG&E in amounts greater than that designated in Section 2.2.1. 16.6.10 The maximum Energy price paid under this Section 16.6 may not exceed the applicable time differentiated price for a non-curtailment hour as provided in Sections 7 and 8. 16.6.11 During hours of curtailment designated under this Section 16.6, SDG&E shall continue to make Firm Capacity payments. Under Option 1, hours of curtailment and energy deliveries during curtailments shall be specifically excluded from the capacity calculations. Under Option 2, for each curtailment hour, payments shall be made pursuant to the following: (i) payments to Seller for firm capacity during each on-peak or semi-peak curtailment hour shall be calculated using Assumed Production Factors derived from Seller's historical performance pursuant to Section 16.6.12, provided, that payments for firm capacity calculated using the Assumed Production Factors shall not exceed the maximum payments provided under Section 9, (ii) nothing in this Section 16.6 shall be construed to entitle Seller to payments for Firm Capacity prior to the Firm Capacity Availability Date, (iii) no firm capacity payment adjustments are applicable for curtailments during off-peak and super offpeak hours since no firm capacity payments are earned during those periods. 16.6.12 Assumed Production Factors a) Subject to the provisions of Sections 16.6.4, 16.6.5 and 16.6.6, during periods of curtailment SDG&E shall pay Seller firm capacity payments, as appropriate, calculated using Assumed Production Factors derived from Seller's historical performance during the on-peak and semi-peak time periods during the previous calendar year. The Assumed Production Factors shall be calculated as follows: APFs = summer kwhp = summer kwhsP C x (summer Hp + Summer Hsp) APFp = summer kwhp C x summer Hp where: APFs = Assumed Production Factor for the summer months for the combined on-peak and semi-peak periods. APFp = Assumed Production Factor for the summer on-peak period Summer Kwhp, summer kwhsp = the respective on-peak and semi-peak Energy (kwh) purchased by SDG&E during the previous calendar year's summer billing period excluding any energy purchased during periods of Curtailment. Summer Hp, summer Hsp = the respective on-peak and semi-peak hours during the previous calendar year's summer billing period excluding scheduled maintenance hours and curtailment hours under Section 16. APFw = winter kwhp +winter kwhsp C x (winter Hp + winter Hsp) APFw = Assumed Production Factor for the winter months for the combined on-peak and semi-peak periods winter kwhp, winter kwhsp = the respective on-peak and semi-peak Energy purchased by SDG&E during the previous calendar year's winter billing period, excluding any Energy purchased during periods of curtailment. C = Firm Capacity Winter Hp, winter Hsp = the respective on-peak and semi-peak hours during the previous calendar year's winter billing period excluding scheduled maintenance and any curtailment hours under Section 16. b) During the first twelve (12) monthly billing cycles following Initial Operation, the Assumed Production Factors shall be calculated based on cumulative available monthly billing data. After the first twelve (12) months and until a full calendar year's billing data is available, the Assumed Production Factors shall be calculated using the most recent twelve (12) monthly billing cycles available. c) During any billing month in which a curtailment period has occurred during the peak or semipeak time periods under Section 16.6, Firm Capacity payments and Bonus Payments made by SDG&E to Seller shall be made as follows: (1) The formula for calculation of Performance Factor (P) as defined in Section 9.6 shall be revised as follows: P = Aasm(1-L) P is less than or C x (B-S) x E equal to 1 where Aasm replaces A and where: Aasm = the sum of the total kilowatt-hours delivered during all on-peak and semi-peak hours excluding any kilowatt-hours delivered during hours of curtailment and excluding any Energy associated with generating levels greater than the Firm Capacity, plus the kilowatt-hours associated with the applicable Assumed Production Factor for the combined time period(s) in which curtailment hour(s) occurred. The kilowatt-hours associated with the Assumed Production Factor shall be calculated by multiplying the appropriate APF times the Firm Capacity times the hours in the on-peak and semi-peak hours in which curtailment was invoked during the monthly billing cycle. 2) The formula for calculation of the Capacity Bonus Factor (CBF) as defined in Section 9.7 shall be revised as follows: CBF = EDasm (1-L) CBF is greater than C x (PP-SP) x .85 equal to 1 where EDasm replaces ED and where: EDasm = the sum of the Energy delivered during the on-peak hours of the peak months excluding any Energy delivered during hours of Curtailment, plus the kilowatt hours associated with the Assumed Production Factor calculated for the summer months. The kilowatt hours associated with the Assumed Production Factor shall be calculated by multiplying the APFp times the Firm Capacity times the number of summer on-peak hours in which curtailment was invoked during the billing cycle. 16.6.13 During hours of curtailment designed under this section 16.6, Seller shall have the right to sell such curtailed energy to a third party. It is Seller's obligation not to sell the curtailed energy on a firm basis. If Sell has elected to sell energy to a third party during curtailment period, SDG&E shall have the right to recall such energy for delivery to SDG&E during such curtailment period upon giving Seller one (1) hour prior notice of its desire to suspend curtailment. SDG&E will only suspend curtailment if circumstances change the assumptions underlying the scheduling of the curtailment. Seller shall use its best efforts to recommence deliveries to SDG&E should SDG&E suspend curtailment prior to the time such curtailment period was scheduled to end. 17. DEFAULT AND REMEDIES 17.1 If either Party defaults in the due performance or observance of any term or condition of this Agreement, said Party shall be in default. Upon the occurrence of any default and at any time thereafter so long as the same shall be continu- ing, the non-defaulting Party may, by notice to the defaulting Party specifying the nature of such default, declare this Agree- ment to be in default. The defaulting Party must remedy such default within the time specified in this Agreement, or, if no time is specified, within thirty (30) days after receiving written notice from the non-defaulting Party. In the event that the defaulting Party fails to cure its default within such period of time, the non-defaulting Party may at any time thereafter exe- rcise, at its election, any rights or remedies it may have under this Agreement, at law or in equity to enforce the terms hereof, including, but not limited to, monetary damages, injunctive rel- ief, specific performance and termination of this Agreement. 17.2 Nothing in this Agreement is intended to limit SDG&E's right to demand and Seller's obligation to provide adequate assurance in the circumstances described in the Uniform Commercial Code. The Parties specifically intend that such rights and obligations shall exist whether or not the Uniform Commercial Code otherwise applies. 17.3 Liquidated Damages: Seller agrees to pay SDG&E in event of Seller's default, as Liquidated Damages and not as a penalty, the amount calculated pursuant to this Section 17. The Parties agree that said calculations represent a reasonable endeavor to estimate fair compensation for SDG&E's foreseeable losses associated with Seller's failure to deliver Firm Capacity that might result from Seller's default or from a reduction in Firm Capacity under this Agreement. The amount of Seller's Liquidated Damages payment shall be reduced by the Project Fee, if any, paid to SDG&E pursuant to Section 4 of this Agreement; provided, however, if the amount of Seller's Liquidated Damages payment is less than the Project Fee paid to SDG&E pursuant to Section 4 of this Agreement, Seller shall not be entitled to a refund of the Project Fee or any portion thereof. This Section 17 shall not preclude or limit SDG&E's entitlement to monetary damages for losses other than for failure to deliver Firm Capacity or resulting from other events of Seller's default. 17.4 In the event of default, SDG&E shall bill Seller for all amounts due under this Agreement including the amounts calculated in Section 17. Seller shall pay interest on all amounts due from the date of notice of default, compounded monthly, at an interest rate equal to the lower of (a) the maximum rate allowed by law, or (b) one-twelfth of the most recent month's interest rate on Commercial Paper (prime, three months) published in the Federal Reserve Statistical Release, G.13, (or if such publication is no longer being issued, the closest similar publication), plus 50 basis points (See Exhibit E). Seller shall pay SDG&E within thirty (30) calendar days of receipt of SDG&E's bill. 17.5 The non-defaulting party shall have the right to offset any amounts due it from the defaulting party against any present or future payments it owes to the defaulting party and may at all times pursue any other remedies available to it. 17.6 For purposes of this Section 17, "Termination Payment A" shall mean an amount equal to the difference between payments for Firm Capacity to date based on the original Agreement length and payments that would have been made, based upon the period of Seller's actual performance, up to the date of reduction or termination, plus interest as set forth in Section 17.4. 17.6.1 If Seller terminates this Agreement, or all or part of the Firm Capacity stated in Section 2.2.1 with the following prescribed written notice: Amount of Capacity Terminated Length of Notice Under 5,000 kw 12 months 5,000 kw to 10,000 kw 36 months 10,000 kw to 20,000 kw 48 months 20,001 kw and over 60 months Seller shall refund to SDG&E Termination Payment A as described in Section 17.6. SDG&E shall then make capacity payments to Seller for the remainder of Seller's perfor- mance, if any, at an adjusted capacity price. 17.6.2 If Seller terminates this Agreement, or all or part of the Firm Capacity stated in Section 2.2.1, without the notice prescribed in Section 17.6.1, Seller shall pay SDG&E "Termination Payment B". Termination Payment B shall consist of the sum of (a) Termination Payment A and (b) a one-time payment. The one-time payment shall be equal to the amount of Firm Capacity being terminated times the difference between the Current Capacity Price on the date of termination for a term equal to the balance of the term of the Agreement and the Firm Capacity price. This product shall be pro-rated for the length of notice given, if any, by taking the difference between the amount of months of notice prescribed minus the amount of months of notice given and dividing by twelve (See Exhibit E, Example 2). In the event that the Current Capacity Price is less than the Firm Capacity price or the termination or reduction is a result of an uncontrollable force on the part of the Seller, then only Termination Payment A shall apply. 18. ABANDONMENT 18.1 If, in any six (6) month period after the Firm Capacity Availability Date, Seller fails to deliver to SDG&E at least the number of kilowatt hours derived from the product of four hundred and thirty-eight (438) hours times the Firm Capacity rating measured in kilowatts, Seller shall provide to SDG&E all of the following: 18.1(a) a written description of the reason for Seller's low level of performance; 18.1(b) a summary of the action Seller is taking to improve its performance; and 18.1(c) a schedule for bringing Seller's deliveries up to the Firm Capacity rating. 18.2 In any fifteen (15) month period after the Firm Capacity Availability Date, Seller shall deliver to SDG&E not less than the number of kilowatt hours derived from the product of one thousand and ninety-five (1,095) hours times the Firm Capacity rating measured in kilowatts. If, for any reason, Seller fails to deliver this minimum amount, SDG&E may terminate this Agreement on written notice. Unless excused as a result of an Uncontrollable Force, such failure shall constitute a default, entitling SDG&E to its remedies at law and under Section 17 of this Agreement. 19. NONDEDICATION OF FACILITIES Seller does not hereby dedicate any part of the Generating Facility to serve SDG&E, its customers, or the public. SDG&E does not hereby dedicate any part of its system or facilities to serve or accept Energy and Firm Capacity from Seller to any greater extent than may be provided by law. 20. LIABILITY 20.1 Except in the case of Willful Action or sole negligence, neither Party shall hold the other Party, its officers, agents or employees liable for any loss, damage, claim, cost, or expense for loss or damage to property, or injury or death of persons, which arises out of the other Party's ownership, operation or maintenance of facilities on its own side of the Point of Delivery. 20.2 Except as set forth in Section 20.1, each Party agrees to defend, indemnify and save harmless the other Party, its officers, agents, and employees against all losses, claims, demands, costs, or expenses for loss of or damage to property, or injury or death of persons, which directly or indirectly arise out of the indemnifying Party's performance pur- suant to this Agreement; provided, however, that a Party shall be solely responsible for any such losses, claims, demands, costs or expenses which result from its sole negligence or Willful Action. 21. INSURANCE 21.1 Seller, at its own expense, shall secure and maintain in effect during the life of this Agreement the following insu-rance as will protect Seller and SDG&E during the performance of operation hereunder: 21.1.1 General Liability Insurance with a combined single limit for bodily injury and property damage of not less than (a) $1,000,000 each occurrence if the Generating Facility is 100 kw or greater; (b) $500,000 each occurrence if the Generating Facility is between 20 kw and 100 kw; and (c) $100,000 each occurrence if the Generating Facility is 20 kw or less. Such General Liability Insurance shall include coverage for Premises-Operations, Owners and Contractors Protective, Products/Completed Operations Hazard, Explosion, Collapse, Underground, Contractual Liability, and Broad Form Property Damage including Completed Operations. 21.1.2 The liability insurance specified in Section 21.1.1 shall name SDG&E as additional insured and shall contain a severability of interest or cross-liability clause. The requirement to name SDG&E as additional insured shall be waived if such requirement prevents Seller from obtaining insurance as specified herein. 21.2 Certificates of Insurance evidencing the coverages and provision as required in Sections 21.1.1 and 21.1.2 above shall be furnished to SDG&E prior to interconnected operation of the Generating Facility and shall provide that written notice be given to SDG&E at least thirty (30) days prior to cancellation or reduction of any coverage. SDG&E shall have the right, but not the obligation, to inspect the original policies of such insurance. Seller will not be allowed to commence interconnected operations unless evidence of satisfactory insurance has been provided to SDG&E in a timely manner. SDG&E will allow Seller to self-insure in lieu of compliance with the requirements of Section 22.1 under the following conditions: 21.3.1 Seller must be a governmental agency with an established record of self-insurance. 21.3.2 Seller must provide to SDG&E at least thirty (30) days prior to the Operation Date evidence of an acceptable plan to self-insure to a level of coverage equivalent to that required under Section 22.1 21.3.3 If Seller ceases to self-insure to the level required hereunder, or if Seller is unable to provide continuing evidence of Seller's ability to self-insure, Seller shall immediately obtain the coverage required under Sections 21.1. 22. UNCONTROLLABLE FORCE Neither Party shall be considered to be in default with respect to any obligation hereunder, other than the obligations to pay money, if prevented from fulfilling such obligation by reason of an uncontrollable force. The term "uncontrollable force" means unforeseeable causes, other than Forced Outages, beyond the reasonable control of and without the fault or negligence of the Party claiming uncontrollable force, including but not limited to, acts of God, labor disputes, sudden actions of the elements, actions by any legislative, judicial or regulatory agency which conflict with the terms of this Agreement, and actions by federal, state, municipal, or any other government agency. Whichever Party is rendered unable to fulfill any obligation by reasons of uncontrollable forces shall give prompt written notice of such fact to the other Party and shall exercise due diligence to remove such inability with all reasonable dispatch. Nothing in this Agreement shall require a Party to settle any strike or labor dispute in which it is involved. 23. NON-WAIVER None of the provisions of this Agreement shall be considered waived by either Party except when such waiver is given in writing. The failure of either Party to insist in any one or more instances upon strict performance of any of the provisions of this Agreement or to take advantage of any or its rights hereunder shall not be construed as a waiver of any such provisions or the relinquishment of any such rights for the future, but the same shall continue and remain in full force and effect. 24. SUCCESSORS & ASSIGNS 24.1 This Agreement shall be binding upon and inure to the benefit of the respective successors and assigns of the Parties. 24.2 Neither Party shall voluntarily assign its rights nor delegate its duties under this Agreement, or any part of such rights or duties, without the written consent of the other Party, except in connection with the sale or merger of a substantial portion of its properties. Any such assignment or delegation made without such written consent shall be null and void. Consent for assignment will not be withheld unreasonably. Such assignment shall include, unless otherwise specified therein, all of Seller's rights to any refunds which might become due under this Agreement. 25. EFFECT OF SECTION HEADINGS Section headings appearing in this Agreement are inserted for convenience only, and shall not be construed as interpretations of text. 26. GOVERNING LAW This Agreement shall be interpreted, governed, and construed under the laws of the State of California as if executed and to be performed wholly within the State of California. 27. SEVERAL OBLIGATIONS Except where specifically stated in this Agreement to be otherwise, the duties, obligations and liabilities of the Parties are intended to be several and not joint or collective. Nothing contained in this Agreement shall ever be construed to create an association, trust, partnership, or joint venture or impose a trust or partnership duty, obligation or liability on or with regard to either Party. Each Party shall be individually and severally liable for its own obligations under this Agreement. 28. CONDITIONS 28.1 This Agreement, other than Section 28, and Sections 4.1, 4.2.1, 4.2.2, and 5.3, is contingent on SDG&E obtaining an order from the CPUC that (i) SDG&E's payments made to Seller under this Agreement are recoverable, through SDG&E's Energy Cost Adjustment Clause, subject to review of the reasonableness of SDG&E's performance under the Agreement, and-(ii) this Agreement is reasonable and SDG&E's entering into this Agreement is prudent. SDG&E will use best efforts and Seller shall provide such reasonable assistance as SDG&E may request in order to expedite obtaining such approval. Both Parties shall evaluate whether the CPUC has approved this Agreement based upon the above criteria. To the extent that the CPUC imposes conditions in its decision which increase either Party's risk in any respect beyond that which would be present, in the reasonable judgement of such Party, had the CPUC merely made the order specified in (i) and (ii) above, such Party may notify the other that the Agreement has not been Approved by the CPUC. Within ten (10) days of both Parties' receipt of the CPUC decision, each Party shall notify the other in writing of its determination that the decision (a) approves this Agreement, or (b) does not approve this Agreement, based on the criteria above. If either Party determines that the CPUC decision does not approve this Agreement, the Parties shall meet forthwith to modify the Agreement in a manner to preserve its economic integrity, and resubmit it to the CPUC, unless the Parties deem it unnecessary and provide written notice to each other consistent with this Section 28.1. 28.2 Upon both Parties' providing notice to the other that this Agreement has been approved by the CPUC, the condition set forth in Section 28.1 shall be deemed fulfilled. IN WITNESS WHEREOF, the Parties have caused Agreement to be executed in their respective names, in duplicate by their respective official representatives as of the day and year last written below.

EXHIBIT E REDUCTION AND TERMINATION PAYMENT EXAMPLE These examples are for demonstration purposes only and should not be construed as a projection of SDG&E Actual Termination Payments. Example 1: Termination with 36 months written notice given 12 years after the Operation Date for termination 15 years after the Operation Date or on December 31, 1999. Assumptions for this example: Contract Capacity - 10 megawatts (10,000 kilowatts) Contract Term - 25 years Operation Date - January 1, 1985 Contract Capacity Price - $115 per kilowatt per year Monthly Interest Rate - 1% per month (assumed to be constant) (a) Total Capacity Payment made = $115/kW-yr x 10,000 kw = $1,150,000 per year (b) Total Capacity Payments which would have been made for a 15 year Contract Term = $100/kW-yr x 10,000 kw = $l,000,000 per year. (c) The difference between (a) and (b) of annual overpayments = $1,150,000 - $l,000,0000/yr = $150,000/yr Termination Payment A is then the value at the end of the 12th year of the sum of the annual overpayments multiplied by a one (1%) percent per month interest charge. Termination Payment A: $150,000/yr x 1 yr/12 months x (Compound Amount Factor at 1% per month for 12 years) = $3,988,269. SDG&E would then pay QF $100/kW-yr for the remaining 36 months of revised contract term. Example 2: Termination without prescribed notice 12 years after the Operation Date or on December 31, 1997. Assumption for this Example: Contract Capacity - 10 megawatts (10,000 kilowatts) Contract Term - 25 years Operation Date - January 1, 1985 Contract Capacity Price - $115 per kilowatt per year Monthly Interest Rate - 1% per month (Assumed to be constant) Length of Notice Given - 3 months Termination Payment B is equal in the sum of Termination Payment A (using the same methodology as in Example 1 above), and a one-time payment, as follows: Termination Payment A (a) Total Capacity Payment made = $115/kW-yr x 10,000 kw = $l, 150,000/yr (b) Total Capacity Payment which would have been made using the same Capacity Payment Schedule in effect at the time of execution for a 12 year contract term = $93/kW-yr x 10,000 kw = $930,000/yr (c) The difference between (a) and (b), of overpayment $1,150,000 - $930,000 = $220,000/yr Termination Payment A is then the value at the end of the 12th year of the sum of the annual overpayments multiplied by one (1%) percent per month interest charge. Termination Payment A: = $220,000/year x 1 year/12 months x (Compound Amount Factor at 1% month for 12 years) = $5,849,460 One Time Payment The payment can be formulated as follows: = (Amount of Firm Capacity Terminated) x (Current Capacity Price - Firm Capacity Price) x (Amount of Notice Prescribed - Amount of Notice Given) 12 months/year = (10,000 kW)(200 S/kW-yr - 115 $/kW-yr) (36-3 mos) (12 mos/yr) = $2,337,500 Termination Payment B Termination Payment B = Termination Payment A + One Time Payment = $5,849,460 + $2,337,500 = $8,186,960 SAN DIEGO GAS & ELECTRIC COMPANY Revised Cal.P.U.C Sheet No.5083-E San Diego, California Cancelling Original Cal.P.U.C. Sheet No.4242-E Sheet 1 EXHIBIT F RULE 21 CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES A. General 1. This Rule presents the design and operating guidelines that should be applied to Cogeneration and Small Power Production sources that meet the criteria for a Qualifying Facility (QF) as defined by Title 18, Code of Federal Regulation (CFR) Section 292.101(b)(1). These guidelines are necessary to facilitate safe integration of customer generation into the utility's system. In addition, the QF must also comply with the utility's applicable rules regulations. 2. These guidelines will cover 1) customer design requirements and operating procedures and 2) utility design requirements and operating procedures. 3. For the purpose of simplicity, the term customer will be used in the guidelines to refer to both cogenerators and small power producers. B. Customer Systems Description 1. The customer may elect to use any of a variety of energy sources including solar, wind or other alternative energy sources, in addition to conventional fossil fuels. The end conversion for connection to the utility's system must provide 60Hz alternating current. 2. The customer may elect to run his generator in parallel with the utility or as a separate system with capability of non-parallel load transfer between the two independent systems. The requirements for these two methods of operation are outlined below. C. Separate System (See Supplement I in Section K.) 1. A separate system is defined as one in which there is no possibility of connecting the customer's generation in parallel with the utility's system. For this design to be practical, the customer must be capable of transferring load between the two systems in an open transition or non-parallel mode. This can be accomplished by either an electrically or mechanically interlocked switching arrangement which precludes operation of both switches in the closed position. The customer will be required to provide protection to ensure adequate clearing of faults on his own system. Advice Ltr. No.603-E-SUPP. Issued by Date Filed April 13, 1984 Decision No.83-10-093 RONALD K. FULLER Effective May 13,1984 84-03-092 Vice President-Regulatory Services Resolution No. Sheet 2 RULE 21 (Continued) CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES C. Separate System (See Supplement I in Section K.) (Continued) 2. If the customer has a separate system, the utility will require verification that the transfer scheme meets the non parallel requirements. This will be accomplished by approval of drawings by the utility in writing and, if the utility so elects, by field inspection of the transfer scheme. The utility will not be responsible for approving the customer's generation equipment and assumes no responsibility for its designor operation. 3. Many Uniterruptible Power Supply (UPS) systems do not specifically meet the separate system criteria. However, if they are not capable of backfeed they will be classified as a separate system. If they can backfeed, they must meet the requirements of parallel operation. D. Parallel Operation A parallel system is defined as one in which the customer's generation can be connected to a bus common with the utility's system. A transfer of power between the two systems is a direct and generally desired consequence. For this operation to be practical and safe, the customer's equipment must meet the following conditions: 1. General Design Requirements a. The customer's installation must meet all applicable national, state, and local construction and safety codes. b. All interconnection equipment at the customer's facility shall be installed and maintained by the customer. If, after review of the customer's design, it is determined that in addition, equipment need be installed on the utility through a power purchase or interconnection agreement with the customer and in accordance with this Rule. Sheet 3 RULE 21 (Continued) CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES D. Parallel Operation (Continued) 1. General Design Requirements (Continued) c. A manual load break disconnect device shall be available at or near the customer's main service point(s). This disconnect device may be owned by either party but the utility must have preemptory control for utility outages or switching. The disconnect device must be capable of being locked in the open position if the customer has access to the disconnect device (see Section K.2.a.). d. Voltage regulation equipment will be required on the customer's generator to maintain service voltage within normal utility limits (not required under 100 Kw). e. Generator characteristics shall be specified and the connection to the utility's system shall be designed to limit voltage harmonic distortion to less than 3% for any single frequency and to less than 5% total harmonic content. If harmonic distortion causes interference to other utility customers, the responsible party will redesign his system to eliminate such interference. f. The customer shall submit drawings and schematics of interconnecting equipment and associated protection to the utility for review and approval. Typical required drawings will include, but not necessarily be limited to the following prints: single line diagram, relay functional, metering on line and switch gear details, circuit breaker open and close control circuits. The utility will review only those portions of the drawings and schematics which apply to metering and the protection of the utility system. The utility assumes no responsibility for review or approval of equipment or circuit drawings pertaining to the protection of the customer's system. Sheet 4 RULE 21 (Continued) CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES D. Parallel Operation (Continued) 2. General Operating Requirements a. The customer must maintain service voltage within normal utility limits. If high or low voltage complaints or flicker complaints result from operation of the customer's generation, such generating equipment shall be disconnected until the problem is resolved. b. The customer shall discontinue parallel operation when requested by the utility: (1) To facilitate maintenance or repair of utility facilities; (2) During system emergencies; (3) When the customer's equipment is operating in a hazardous manner or is operating such that it is interfering with other customers on the system. NOTE: The utility may disconnect the customer from the utility's system at any time without prior notification, as system conditions may dictate. c. The customer may not commence parallel operation of its generator(s) until final written approval has been given by the utility. The utility reserves the right to inspect the customer's facility and witness testing of any equipment or devices associated with the interconnection. d. The utility reserves the right to inspect the customer's facilities whenever it appears that the customer is operating in an unsafe or harmful manner to the utility's facilities, personnel or other customers. Sheet 5 RULE 21 (Continued) CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES D. Parallel Operation (Continued) 2. General Operating Requirements (Continued) e. To assure the continued and safe operation of the interconnection between the utility and the customer, the utility recommends that the customer maintain and calibrate his equipment and protective devices associated with the interconnection to the utility on a repetitive basis. The utility reserves the right to require customers to provide the utility with maintenance and calibration reports. E. Customer Generation Less than 100 Kw (See Supplement II in Section L.) 1. The utility shall provide and install metering, at a location acceptable to the utility, as necessary to comply with applicable customer generation gas and electric rate schedules, power purchase contracts, or utility requirements. The installation, operation, and maintenance costs of these metering facilities shall be borne by the customer, except as provided in Section J.l.d. 2. Where service is provided at or below 480 V, the customer is to be served by a dedicated distribution transformer except in the following circumstances: a. The generator is under 10 kw, or b. The generator is under lOO kw and is an induction generator wherein the customer explicitly provides for 24-hour immediate utility access to all interconnection facilities as provided in Rule l6.A.l.a.(1). 3. The customer should maintain his power factor within a reasonable range. For small generators, power factor correction may not be desirable. 4. The customer will be required to provide suitable devices to ensure adequate protection for the following: a. All faults on the customer's system. b. All faults on the utility's system. c. Backfeed or start-up of a customer's generator(s) into a dead utility busSheet 6 RULE 21 (Continued) CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES E. Customer Generation Less Than 100 kw (See Supplement II in Section L.) (Continued) 5. The following customer protective devices are required as a minimum to effect connection and separation of the utility and customer systems. For induction generators below 10 kw, the following are recommended but not required. The customer will still be responsible for providing protection for the conditions of Section E.4. a. Individual phase overcurrent trip devices. b. Undervoltage trip devices. c. Underfrequency trip devices. d. Synchronizing or equivalent controls to ensure a smooth connection with the utility's system. 6. The requirements listed in Section E.5. are based on the utility's forecast that there will be a relatively small amount of customer generation versus load for any particular line on the utility's system. If a heavy saturation of small power production on some line(s) does occur at a future time, future customers may be required to provide additional protection at that time. Where an induction generator is to be installed, some of the trip devices may be waived. Permission to waive certain devices will be given only after a check of the supply circuit (for capacitance) has been made and it has been determined that the customer's generation will not be able to backfeed the utility's system. 7. The customer shall not reconnect his generator after a protective device trip unless his system is energized from the utility source or unless he has isolated his system from the utility.Sheet 7 RULE 21 (Continued) CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES F. Customer Generation Capacity 100 kw-1Mw (See Supplement III in Section M.) 1. The utility shall provide and install metering, at a location acceptable to the utility, as necessary to comply with applicable customer generation gas and electric rate schedules, power purchase contracts, or utility requirements. The installation, operation, and maintenance cost of these metering facilities shall be borne by the customer. 2. The customer's generator(s) shall be designed and operated to limit the adverse affects of reactive power flow on the utility's system under all reasonably probable load conditions. Generators shall be operated in a manner to satisfy the reactive power requirement of the customer's own load within the limits of the generator's capability unless otherwise specified by the utility. a. For synchronous generators, sufficient generator reactive capability shall be provided to withstand normal voltage changes on the utility's system. b. For induction generators, capacitor installations will likely be required for reactive power support. The cost of such capacitors will be borne by the customer. 3. The customer shall install relaying to provide adequate protection for the following: a. All faults on the customer's system. b. All faults on the utility's system. c. Unbalanced or single phase conditions on the utility's system. d. Backfeed or start-up of the customer's generator(s) into a dead utility bus.Sheet 8 RULE 21 (Continued) CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES F. Customer Generation Capacity 100 kw-1 (See Supplement III in Section M.) (Continued) 4. Protective devices required are as follows: a. Individual phase overcurrent trip devices. b. Undervoltage trip devices. c. Sensitive current unbalance relays. d. Synchronizing controls; either automatic or manual. e. Over/under frequency trip devices. 5. The customer shall not reconnect hi generator after a protective device trip unless his system is energized from the utility source, or unless he has isolated his system from the utility. To prevent such hazardous connections, the protective devices specified in Sections F.5.b. and F.4.d. are required. In addition generator control circuit(s) must be designed to prevent accidental generator connection to a dead utility system. Design variations are acceptable provided the requirements of Section F.3. are satisfied. G. Customer Generation Capacity Greater the 1 Mw (See Supplement IV in Section N.) 1. The utility shall provide and install metering, at a location acceptable to the utility, as necessary to comply with applicable customer generation gas and electric rate schedules, power purchase contracts, or utility requirements. The installation, operation, and maintenance costs of these metering facilities shall be borne by the customer. Sheet 9 RULE 21 (Continued) CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES G. Customer Generation Capacity Greater the 1 Mw (See Supplement IV in Section N.) (Continued) 2. The customer's generator(s) shall be designed and operated to limit the adverse affects of reactive power flow on the utility's system under all reasonable probable load conditions. Generators shall be operated in a manner to satisfy the reactive power requirement of the customer's own load within the limits of the generator's capability unless otherwise specified by the utility. a. For synchronous generators, sufficient generator reactive capability shall be provided to withstand normal voltage damages on the utility's system. b. For induction generators, capacitor installations will likely be required for reactive power support. Such capacitors will be at the expense of the customer. 3. The customer shall install relaying to provide adequate protection for the following: a. All faults on the customer's system. b. All faults on the utility's system. c. Unbalanced or single phase conditions, or deteriorating voltage waveform conditions on the customer's generator(s). d. Backfeed or start-up of the customer's generator(s) into a dead utility bus. 4. Protective devices required are as follows: a. Individual phase overcurrent trip devices. b. Sensitive ground protection. c. Over/under voltage trip devices. Sheet 10 RULE 21 (Continued) CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES G. Customer Generation Capacity Greater than 1 Mw (See Supplement IV in Section N.) (Continued) 4. (Continued) d. Sensitive current unbalance relays. e. Synchronizing controls; either automatic or manual synchronizing supervised by a synchronizing relay. f. Over/under frequency trip devices. g. Telemetering or supervisory equipment (See Sections G.6., G.7., G.8., and I.2.). 5. The customer shall not reconnect his generator after a protective device trip unless his system is energized from the utility source, or unless he has isolated his system from the utility. To prevent such hazardous connections, the protective devices specified in Sections G.4/c. and G.4.e. are required. In addition, generator control circuit(s) must be designed to prevent accidental generator connection to a dead utility system. Design variations are acceptable provided the requirements of Section G.3. are satisfied. 6. Telemetering of Plant Output Telemetering of the plant output (Mw, Mvar) to the Utility Control Center, at customer's cost, is required when the output of the customer's generation is greater than 2 Mw, and the generation is operating in parallel with the utility. 7. Utility Supervisory Control When the customer is selling firm capacity greater than or equal to 5 Mw to the utility, one of the following is required:Sheet 11 RULE 21 (Continued) CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES G. Customer Generation Capacity Greater than 1 Mw (See Supplement IV in Section N.) (Continued) 7. Utility Supervisory Control; (continued) a. Complete supervisory control system allowing operation of plant generation from the Utility Control Center. b. Manning of generation facilities during all hours of operation and all periods in which customer's facility may be dispatched to allow operation as directed from the Utility control Center. 8. Control and Indication of Customer's Main Breaker When the total output of the customer's generation is less than 5 Mw, control and indication of the customer's main breaker will not generally be required. However, this decision will be made on an individual basis by the utility. H. Utility System Description 1. The vast majority of, if not all, customers with generation will be connected to the utility's distribution system. This is a radial system and past experience indicates these loads are of a passive nature. The encouragement of customers to install onsite generation, however, will make backfeed a distinct possibility. The incorporation of protective devices on the customer's equipment cannot be relied upon to prevent all possibilities of backfeed. Since backfeed is probable, the following design and operating requirements must be incorporated. 2. Utility Design Requirements a. A means of disconnection must be available on both sides of the utility metering; must be under the control of the utility; and shall be applied to all customers with parallel generation. Sheet 12 RULE 21 (Continued) CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES H. Utility System Description (Continued) 2. Utility Design Requirements (Continued) a. (Continued) This can be accomplished with switches, load break elbows, cutouts or secondary breakers. Customer disconnects can also be used provided that: (1) The switches meet with utility approval. (2) The utility has pre-emptive control. b. Transformers feeding customers with parallel generation shall be identified with a special tag attached to the transformer or pole. This will notify field crews of the possibility of backfeed. Incoming load data sheets should be flagged and used to initiate orders to tag poles. c. All maps and diagrams used by System Operators to direct switching operations shall have sources of parallel generation identified. d. A supervisory control and monitoring system will be incorporated for those customers as specified in Sections G.7. and G.8. I. Utility Operation Procedures 1. As specified in Section H.1., backfeed from customer generation is a distinct possibility. To maintain safe working conditions, strict adherence to safety rules is required. Utility procedure is to ground de-energized lines and equipment upon which work will be performed. 2. The utility will exercise direct control over customer generation to the extent allowed by the contract and elsewhere in the Rule. A supervisory system is required for this control (see Sections G.7 and G.8). Sheet 13 RULE 21 (Continued) CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES I. Utility Operation Procedures (Continued) 3. The utility must have discretionary control over all customer generation, independent of magnitude, during outages, equipment maintenance or emergencies. 4. Additional safety control or procedures may be required as experience dictates. 5. It is normal utility practice to utilize multi-shot high speed reclosing on its distribution circuits. J. Interconnection and Line Extension/Line upgrade Facility Cost* 1. General a. The installation and maintenance costs of facilities related to the interconnection of a customer's facility (interconnection facilities) to the utility's system, utilizing the utility's normal standards, shall be borne by the customer. b. The installation and maintenance costs of any line extension line upgrade facilities, utilizing the utility's normal standards, shall be borne by the customer. Line extension/line upgrade facilities are defined as all facilities exclusive of interconnection facilities, determined by the utility to be necessary to connect the utility's system to the customer's point of delivery in order to accept the output of the customer's generating facility. The cost of any portion of the line extension/line upgrade undertaken to serve future additional customers shall be borne by the utility. * As used in this Section J. only, the terms "interconnection facilities" and "line extension/line upgrade facilities" refer only to such facilities to be owned and maintained by the utility. Sheet 14 RULE 21 (Continued) CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES J. Interconnection and Line Extension/Line Upgrade Facility Cost (Cont'd.) 1. General (Continued) c. The customer shall be responsible for the costs of exploring the feasibility of a project or its interconnection with the utility's system, including reasonable advance charges imposed by the utility for feasibility studies. A transmission line study for any customer shall be completed by the utility within the time period identified by the utility in accordance with the applicable procedures as established by the California Public Utilities Commission. d. The customer shall be responsible for costs of metering, telemetering (to the extent required under this Rule), and safety checks except to the extent that, under the utility's existing other rules, a comparable customer would not be similarly charged. Where the customer's generating facility is less that 20 kw, except those customers remaining on Schedule AD after June 30, 1987, and customer does not require that power delivered to the utility be measured on a time-of-delivery basis, the utility will bear the cost of installing, operating and maintaining one standard watt-hour meter (and current transformers if required) to measure power flows from the customer to the utility. The customer shall provide and install necessary meter sockets and enclosure equipment at or near the point of delivery. e. The customer shall be responsible for the installation and maintenance costs of only those future utility system alterations which are necessary to maintain the California Public Utilities Commission's adopted interconnection standards for the customer's particular interconnection facilities. Said standards shall be those in effect at the time customers and utility sign the power purchase or interconnection agreement. Should a line extension/line upgrade not be directly required by or beneficial to the customer, the customer shall be treated like any other customer on the utility's system. Sheet 15 RULE 21 (Continued) CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES J. Interconnection and Line Extension/Line Upgrade Facility Cost (Cont'd) 1. General (Continued) f. When the customer wishes to continue to reserve interconnection and line extension/line upgrade facilities which were previously paid for by the customer, but have been idled by an energy sale conversion, the utility shall continue to charge the customer an operation and maintenance (O&M) charge for these facilities. When the customer no longer needs the facilities for which he has paid, or fails to pay the required O&M charge, a termination payment due to the utility or customer shall be calculated in accordance with the applicable sections of the Rule and the power purchase or interconnection agreement. g. The utility shall treat any money collected from a customer for a line extension/line upgrade that accommodates a second customer in the same manner as customer advances would be treated under the utility's regular line extension rules for other customers. h. The O&M charge required under this Section J. shall commence at such time as the facilities are installed and able to be used. 2. Allocation of the utility's Existing Line Capacity For purposes of interconnecting the customer with the utility, existing capacity on the utility's transmission and/or distribution system and a priority to such line capacity will be allocated as follows: a. For a customer who receives either a final Standard Offer #4, a Standard Offer #2, or a Uniform Standard Offer #1, the following shall apply; (1) For a customer who bids for and receives a final Standard Offer #4 Power Purchase Agreement, entitlement to existing capacity on the utility's transmission and/or distribution system and a priority to such line capacity will be established as of the date its bid is accepted by the utility; or Sheet 16 RULE 21 (Continued) CUSTOMER-OWNED GENERATION--QUALIFIED FACILITIES J. Interconnection and Line Extension/Line Upgrade Facility Cost (Cont'd) 2. Allocation of the Utility's Existing Line Capacity (Continued) a.
