Sheet No. 6047-E Rule No. 21 COGENERATION AND SMALL POWER PRODUCTION INTERCONNECTION STANDARDS A. General. This rule sets forth requirements and conditions for interconnected non Company-owned generation where such generation may be connected for (1) parallel operation with the service of the Company or (2) isolated operation with standby or breakdown service provided by the Company. For purposes of this rule, the interconnecting entity shall be designated the Producer. B. Conditions. 1. An agreement executed by the Company and the Producer shall be required for interconnected service. Terms for the purchase of power by the Company if applicable, shall be included therein. 2. Interconnection with the Company's system may not be made until and unless the Company has determined that the interconnection complies with the design and operating requirements set forth herein. 3. Where interconnection protective equipment is owned, operated and maintained by the Producer, the Producer shall be responsible for damages to the Company or to others arising out of the misoperation or malfunction of the Producer-owned equipment. 4. The Producer is solely responsible for providing adequate protection for the Producer's facilities interconnected with the Company's system. C. Design and Operating Requirements. Each generation facility which is or can be connected to the Company's electric system shall be designed and operated so as to prevent or protect against the following adverse conditions on the Company's system. These conditions can cause electric service degradation, equipment damage, or harm to persons: 1. Inadvertent and unwanted re-energization of a utility deadline or bus. 2. Interconnection while out of synchronization. 3. Overcurrent. 4. Utility system load imbalance. 5. Ground faults. 6. Generated alternating current frequency outside permitted safe limits. 7. Voltage generated outside permitted limits. 8. Poor power factor. 9. Harmful wave forms. The necessary protective equipment (relays, switchgear, transformers, etc.) can be provided by the Producer or by the Company. Explanatory information, operating rules and guidelines for meeting the above requirements for small (below 100 kW), medium (100-1000 kW), and large (above 1000 kW) facilities are contained in the Company's guidelines for cogenerators and small power producers. Copies of said guidelines are available from the Company. D. Interconnection Facilities. 1. Interconnection facilities include all required means, and apparatus installed, to interconnect the Producer's generation with the Company's system. Where the Producer desires to sell power to the Company, interconnection facilities include also all required means, and apparatus installed, to enable the Company to receive power deliveries from the Producer.

Interconnection Facilities. (Continued) a. Connection, transformation, switching, communications, control, protective and safety equipment; and b. Any necessary reinforcements and additions to the Company's system by the Company. 2. Where interconnection facilities are to be installed for the Producer's use as added facilities, the Producer shall advance to the Company the installed cost of the added facilities. At the Producer's option, and where such Producer's generation is a qualifying facility and the Producer has established credit worthiness to the Company's satisfaction, the Company shall finance those added facilities it deems to be removable and reusable equipment. Such equipment shall include, but not be limited to, transformation, disconnection, and metering equipment. Added facilities provided under either of the foregoing arrangements are subject to the monthly charge as set forth in Section H of the Company's Rule No. 2. Description of Service, on file with and authorized by the Commission. 3. When a Producer wishes to reserve facilities paid for by the Producer, but idled by an energy sale conversion, the Company shall impose a special facilities charge reimbursing the Company for costs related to its operation and maintenance of the facility. When a Producer no longer needs facilities for which it has paid, the Producer shall, at a minimum, receive from the Company credit for the net salvage value of the facilities dedicated to Company use. If the Company is able to make use of these facilities to serve other customers, the Producer shall receive the fair market value of the facilities determined as of the date the Producer either decides no longer to use the facilities or fails to pay the required maintenance fee. 4. The Producer shall be responsible for the costs of exploring the feasibility of a project or its interconnection with the Company system, including reasonable advance charges imposed by the Company for feasibility studies. 5. An interconnection line study for any Producer shall take no more than one year to complete. 6. The Producer shall be responsible for costs of telemetering and safety checks except to the extent that, under the Company's effective tariffs, a comparable customer would not be similarly charged. 7. The Company shall, upon request, give the Producer a binding estimate for line extension and interconnection costs; however, such estimates shall be in effect for a period not to exceed one year from the date provided. A reasonable breakdown of cost estimates shall also be provided in a form sufficiently detailed and understandable by the Producer. 8. The Company shall have the right to inspect the Producer's interconnection facilities prior to the commencement of parallel operations and require modifications as necessary. 9. The site of interconnection facilities shall be accessible to Company personnel. E. Interconnection Reinforcement and/or Additions. The Company's effective tariffs governing inter-connection costs and added or special facilities agreements shall be applied to line and system reinforcement and/or additions. In addition, the following shall apply: 1. A Producer shall pay for new or additional line capacity if necessary for the Company to receive the Producer's power. 2. The costs of any line reinforcement and/or addition undertaken at the option of the Company to serve additional future customers or Producers shall be borne by the Company.

Sheet No. 6049-E Rule No. 21 COGENERATION AND SMALL POWER PRODUCTION INTERCONNECTION STANDARDS (Continued) E. Interconnection Reinforcement and/or Additions. (Continued) 3. For two or more Producers seeking to use an existing line, a first come, first served approach shall be used. This approach shall require that the first Producer to request an interconnection shall, pursuant to written agreement, have the right to use the existing line and shall incur no obligation for costs associated with future line capacity needed to accommodate other Producers or customers. The Company's Standard Offer and/or power purchase agreements for cogeneration and small power production facilities shall specify the date by which the Producer must begin construction. If that date passes and construction has not commenced, the Producer shall be given 30 days to correct the deficiency after receiving a reminder from the Company that the construction start-up date has passed. If construction has not commenced after the 30-day corrective period, the Company shall have the right to withdraw its commitment to the first Producer and offer the right to interconnect on the existing line to the next Producer in order. If two Producers establish the right of first-in-time simultaneously, the two Producers shall share the costs of any additional line capacity necessary to facilitate their cumulative capacity requirements. Costs shall be shared based on the relative proportion of capacity each Producer will add to the line. 4. The applicable Company tariff provisions shall be applied to a Producer who pays for interconnection reinforcement and/or additions that later accommodate a second Producer as those provisions which would be applied to a comparable Company customer. 5. The Producer shall be responsible for the costs of only those future system alterations which are necessary to maintain the California Public Utilities Commission's adopted interconnection standards for the Producer's particular interconnnection facilities. The relevant interconnection standards shall be those in effect at the time the contract is signed. Should such alterations not be directly required by, or beneficial to the Producer, the Producer shall be treated like any other customer on the Company's system. F. Metering. 1. If the Producer desires to sell electric power to the Company, the Company shall provide, own and maintain at the Producer's expense all necessary meters and associated equipment to be utilized for the measurement of energy and capacity for determining the Company's payment to the Producer pursuant to an applicable agreement. 2. For purposes of monitoring generator operation and determination of standby charges, the Company shall have the right to install generation metering at the Producer's expense. Where the Producer's generation is 10 MW or greater, telemetering equipment may also be required at the Producer's expense. 3. The Producer shall provide, at no expense to the Company, a suitable location for all meters and associated equipment in accordance with Rule No. 16. 4. Where necessary the Company and the Producer shall agree on an appropriate compensation method for transformer losses as specified in the agreement. 5. The Company shall install a ratchet device so as to prevent reverse operation on the meter(s) recording power provided by the Company, and where appropriate in each of the following cases on, (i) the meter(s) recording reactive demand imposed on the Company's electric system, and (ii) the meter(s) recording power purchased by the Company. 6. Provision for meter tests and adjustments of bills or payments to the Producer for meter error shall be consistent with Rule No. 17. SOUTHERN CALIFORNIA EDISON COMPANY P.O.
