7.7.1 Any electrical Generating Facility with a maximum electrical generating capacity of 20 MW or less must comply with these requirements to be eligible to interconnect and operate in parallel with the Utility's Electrical Distribution System. These requirements shall apply to all interconnecting Generating Facilities that are intended to operate in parallel with the Utility's Electrical Distribution System, irrespective of whether the Applicant intends to generate energy to serve all or a part of the Applicant's load, or to sell the output.

7.7.2 In order to ensure system safety and reliability of interconnected operations, all interconnected Generating Facilities shall be constructed and operated by Generator in accordance with these requirements and all other applicable federal, state, and local laws and regulations. It is the sole responsibility of the Generator to ensure compliance with such requirements and all applicable laws and regulations.

7.7.3 Prior to initial operation, all Generators must notify the Utility once their installed Generating Facility passes electrical inspection by the appropriate authority; execute the appropriate interconnection agreement contained in the Appendix, as well as any other agreement(s) required by this DPP for the disposition of the Generating Facility's electric power output. The interconnection agreement between the Utility and Generator establishes the interconnection standards, cost allocation and billing agreements, and on-going maintenance and operation requirements.

7.7.4 This DPP and the "Interconnection Requirements, Procedures, Applications, and Agreements for Generating Facilities Not Greater Than 20 MW" document (the "Small Generator Interconnection document") govern the terms and conditions under which the Applicant's Generating Facility will interconnect with, and operate in parallel with, the Utility's Electrical Distribution System. This DPP and the Small Generator Interconnection document do not govern the settlement, purchase or delivery of any power generated by Applicant's Generating Facility. The purchase or delivery of power, including net metering of electricity pursuant to Chapter 80.60. RCW, and other services that the Applicant may require will be covered by separate agreement or pursuant to the terms, conditions and rates as may be from time to time approved by the Utility. Any such agreement shall be complete and fully executed prior to initial operation and properly filed with the Utility.

7.7.5 Applicant or Generator shall promptly furnish the Utility with copies of such plans, specifications, records, and other information relating to the Generating Facility or the ownership, operation, use, or maintenance of the Generating Facility, as may be reasonably requested by the Utility from time to time.

7.7.7 To ensure reliable service to all Utility customers and to minimize possible problems for other customers, the Utility will review the need for a dedicated-tosingle-customer transformer. Interconnecting Generating Facilities may require a separate transformer. If the Utility requires a dedicated transformer, the Applicant or Generator shall pay for all costs of the new transformer and related facilities.

7.7.8 Metering.

7.7.8.1 Net Metering for Solar, Wind, Hydropower and Fuel Cells as set forth in RCW 80.60: The Utility shall install, own and maintain a kilowatt-hour meter, or meters as the installation may determine, capable of registering the bi-directional flow of electricity at the point of common coupling at a level of accuracy that meets all applicable standards, regulations and statutes. The meter(s) may measure such parameters as time of delivery, power factor, voltage and such other parameters as the Utility shall specify. The Applicant shall provide space for metering equipment. It will be the Applicant's responsibility to provide the current transformer enclosure (if required), meter socket(s) and junction box after the Applicant has submitted drawings and equipment specifications for the Utility approval. The Utility may approve other generating sources for net metering but is not required to do so. Net metering is available to Generating Facilities sized up to 100 kW only.

7.7.8.2 Production Metering: The Utility may require separate metering for production of electricity as required under applicable power purchase or credit programs. This meter will record all generation produced and may be billed separately from any net metering or customer usage metering. All costs associated with the installation of production metering will be paid by the Applicant.

7.7.9 Common labeling furnished or approved by the Utility and in accordance with NEC requirements must be posted on meter base, disconnects, and transformers informing working personnel that generation is operating at or is located on the premises.

7.7.10 As currently set forth for qualifying generation under RCW 80.60, for solar, wind, hydro or fuel cells no additional insurance will be necessary for Level 1 interconnection requests. For other Generating Facilities approved under these requirements but not contained within RCW 80.60, additional insurance, limitations of liability and indemnification may be required by the Utility. The general provisions and requirements of the Small Generator Interconnection document list the recommended insurance fees for Level 2, 3, or 4 interconnection requests.

7.7.11 Prior to any future modification or expansion of the Generating Facility, the Generator will obtain Utility review and approval. The Utility reserves the right to require the Generator, at the Generator's expense, to provide corrections or additions to existing electrical devices in the event of modification of government or industry regulations and standards.

7.7.12 For the overall safety and protection of the utility system, RCW 80.60.020 currently limits interconnection of generation for net metering to 0.25% of the utility's peak demand during 1996. Additionally, interconnection of Generating Facilities to individual distribution feeders will be limited to 10% of the feeder's peak capacity. However, the Utility may, in its sole discretion, allow additional generation interconnection beyond these stated limits.

7.7.13 It is the responsibility of the Generator to protect its facilities, loads and equipment and comply with the requirements of all appropriate standards, codes, statutes and authorities.

7.7.14 Charges by the Utility to the Applicant or Generator in addition to the application fee, if any, will be cost-based and applied as appropriate. Such costs may include, but are not limited to, transformers, production meters, and utility testing, qualification, and approval of non UL 1741 listed equipment. The Generator shall be responsible for any costs associated with any future upgrade or modification to its interconnected system required by modifications to the Utility's Electrical Distribution System or Bulk Electrical System.

7.7.15 Generator may disconnect the Generating Facility at any time; provided that the Generator provides reasonable advance notice to the Utility, unless an emergency condition requires that the Generating Facility be disconnected.

7.7.16 Generator shall notify the Department at the time of the sale or transfer of the Generating Facility, the interconnection facilities or the premises upon which the facilities are located. The Applicant or Generator shall not assign its rights or obligations under any agreement entered into pursuant to these requirements without the prior written consent of the Utility, which consent shall not be unreasonably withheld.

7.7.17 All Generating Facilities must obtain required electrical permit(s) and pass electrical inspection by the proper authority before the Generating Facility will be connected or operated in parallel with the Utility's Electrical Distribution System. Generator shall provide notification to the Utility that the Generating Facility has been installed and inspected in compliance with the local building and/or electrical codes.

If an Applicant is denied approval for interconnection under one level and reapplies within ten business days under another level, the date of Utility receipt of the initial application shall be used for purposes of the order of review. No automatic extension of Utility review periods are allowed due to one proposed Generating Facility's impact on another proposed Generating Facility.

(E) Level 1 Screening Criteria and Process for

Inverter-Based Generating Facilities Not Greater than 100 kW:

1. Application: An Applicant must submit a Level 1 Interconnection Application using the standard form provided in Attachment 1 to these Interconnection Requirements, which may be sent electronically to a recipient designated by the Utility. Within three business days of receipt, the Utility shall acknowledge receipt of the application and notify Applicant whether or not the application is complete. If the application is incomplete, the Utility shall provide a written list detailing all information that must be provided to complete the application. The Applicant shall have ten business days after receipt of the list of incomplete material to submit the listed information, or to request an extension of time to provide such information. Otherwise, the application will be deemed withdrawn. The Utility shall notify the Applicant within three business days of receipt of a revised application whether the application is complete or incomplete. The Utility may deem the application withdrawn if it remains incomplete. An Applicant executes the standard Interconnection Agreement for Level 1 by submitting a Level 1 application.

2. Applicable Screens:

i. For interconnection of a Generating Facility to a radial distribution circuit, the Generating Facility aggregated with all other generation capable of exporting energy on a line section will not exceed 15 percent of the line section's annual peak load as most recently measured at the substation or calculated for the line section. A line section is that portion of the radial distribution circuit to which the Applicant seeks to interconnect and is bounded by automatic sectionalizing devices or the end of a distribution line.

ii. If the Generating Facility is to be interconnected on single-phase shared secondary, then the aggregate generation capacity on the shared secondary, including the Generating Facility, will not exceed 20 kilovolt-amps (kVA).

iii. If the Generating Facility is single-phase and is to be interconnected on a transformer center tap neutral of a 240-volt service, its addition will not create an imbalance between the two sides of the 240-volt service of more than 20 percent of nameplate rating of the service transformer.

iv. The Generating Facility's Generating Capacity cannot exceed the Applicant's existing electrical service entrance capacity.

v. No construction of facilities by the Utility on its own system shall be required to accommodate the Generating Facility. (Meters are not considered facilities.)

vi. For interconnection of a Generating Facility within a Spot Network or Area Network, the aggregate generating capacity including the Generating Facility may not exceed 50% of the Network's anticipated minimum load. If solar energy Generating Facilities are used exclusively, only the anticipated daytime minimum load shall be considered. The Utility may select any of the following methods to determine anticipated minimum load:

a) the Network's measured minimum load in the previous year, if available;

b) five percent of the Network's maximum load in the previous year;

c) the Applicant's good faith estimate, if provided; or

d) the Utility's good faith estimate if provided in writing to the Applicant along with the reasons why the Utility considered the other methods to estimate minimum load inadequate.

3. Time to process screens: Within seven business days after the Utility notifies the Applicant that the application is complete, the Utility shall notify the Applicant whether the Generating Facility meets all of the applicable Level 1 screens.

4. Screens failure: Despite the failure of one or more screens, the Utility, at its sole option, may approve the interconnection provided such approval is consistent with safety and reliability. If the Generating Facility fails one or more of the Level 1 screens and the Utility denies interconnection, then the Utility shall provide the Applicant with detailed information on the reason(s) for failure. The Applicant may reapply for interconnection of the Generating Facility under Levels 2, 3 or 4 as appropriate with an application date based on the initial application date as provided in Section D.

5. Approval: If a Generating Facility meets all of the applicable Level 1 screens, has been approved for connection by an electrical inspector, and is otherwise approved by the Utility, within three business days, the Utility shall send the Applicant a copy of the application form, signed by the Utility, forming the Level 1 Interconnection Agreement. If a Utility does not notify an Applicant in writing or by email within twenty business days whether an application is approved or denied, the Interconnection Agreement signed by the Applicant as part of the Level 1 application shall be deemed effective.

6. Unless extended by mutual agreement of the Parties, within six months of formation of an Interconnection Agreement, the Applicant shall provide the Utility with at least ten business day's notice of the anticipated start date of the Generating Facility.

7. Within five business days of the Applicant's notice of the anticipated start date, the Utility may contact the Applicant to schedule a Utility inspection of the Generating Facility at the Utility's expense. If the Utility does not contact an Applicant to schedule an inspection within five business days of the Applicant's notice of the anticipated start date, the Utility waives its right to inspect the Generating Facility prior to interconnection. Any inspection shall be scheduled to occur within ten business days of the Applicant's notice of the anticipated start date at a time mutually agreeable to the Parties. The Utility may not determine that a Generating Facility has failed the Utility's inspection unless there is evidence of a failure of a Level 1 screen or the Generating Facility does not comply with a standard listed in Section C. If a Generating Facility initially fails a Utility inspection, the Utility shall offer to redo the inspection at the Applicant's expense at a time mutually agreeable to the Parties.

8. Upon delivery to the Utility of evidence of approval by an electrical code official with jurisdiction over the interconnection, an Applicant may begin interconnected operation of a Generating Facility, provided that there is an Interconnection Agreement in effect and that the Generating Facility has not failed an inspection required by the Utility.

iv. The Generating Facility is interconnected to the Utility's Electrical Distribution System as shown in the table below:

v. If the Generating Facility is to be interconnected on single-phase shared secondary, then the aggregate generation capacity on the shared secondary, including the Generating Facility, will not exceed 20 kilovolt-amps (kVA).

vi. If the Generating Facility is single-phase and is to be interconnected on a transformer center tap neutral of a 240-volt service, its addition will not create an imbalance between the two sides of the 240-volt service of more than 20 percent of nameplate rating of the service transformer.

vii. The Generating Facility, in aggregate with other generation interconnected to the distribution low-voltage side of the substation transformer feeding the distribution circuit where the Generating Facility proposes to interconnect, will not exceed 20 MW in an area where there are known or posted transient stability limitations to generating units located in the general electrical vicinity (e.g., three or four transmission voltage level busses from the Point of Common Coupling).

viii. The Generating Facility's Point of Common Coupling will not be on a transmission line.

ix. The Generating Facility's Generating Capacity cannot exceed the Applicant's existing electrical service entrance capacity.

x. No construction of facilities by the Utility on its own system shall be required to accommodate the Generating Facility.

xi. For interconnection of a Generating Facility within a Spot Network or Area Network, the Generating Facility must be inverter-based and use a minimum import relay or other protective scheme that will ensure that power imported from the Utility to the network will, during normal Utility operations, remain above one percent of the network's maximum load over the past year or will remain above a point reasonably set by the Utility in good faith. At the Utility's discretion, the requirement for minimum import relays or other protective schemes may be waived.

3. Time to process under screens: Within fifteen business days after the Utility notifies the Applicant that the application is complete, the Utility shall notify the Applicant whether the Generating Facility meets all of the applicable Level 2 screens.

4. Screens failure: Despite the failure of one or more screens, the Utility, at its sole option, may approve the interconnection provided such approval is consistent with safety and reliability. If the Generating Facility fails one or more of the applicable screens and the Utility denies interconnection, then the Utility shall provide the Applicant with detailed information on the reason or reasons for failure. The Applicant may request the application continue to be processed under Level 2 additional review, Level 3 or Level 4 based on the initial application date as provided in Section D.

5. Approval: If a facility meets all of the applicable screens above or is otherwise approved by the Utility, within three business days the Utility shall send an executed Interconnection Agreement to the Applicant.

6. An Applicant that receives an Interconnection Agreement executed by the Utility shall have ten business days to execute the agreement and return it to the Utility. An Applicant shall communicate with the Utility no less frequently than every six months regarding the status of a proposed Generating Facility to which an Interconnection Agreement refers. Within two years from an Applicant's execution of an Interconnection Agreement, the Applicant shall provide the Utility with at least ten business days notice of the anticipated start date of the Generating Facility.

7. Within ten business days of the Applicant's notice of the anticipated start date, a Utility may require an inspection of the Generating Facility at a time mutually agreeable to the Parties at the Utility's expense. The Utility may determine that a Generating Facility has failed the Utility's inspection unless there is evidence that the interconnection fails a Level 2 screen or the Generating Facility does not comply with a standard listed in Section C. If a Generating Facility initially fails a Utility inspection, the Utility shall offer to redo the inspection at the Applicant's expense at a time mutually agreeable to the Parties.

8. Upon delivery to the Utility of evidence of approval by an electrical code official with jurisdiction over the interconnection, an Applicant may begin interconnected operation of a Generating Facility, provided that there is an Interconnection Agreement in effect and that the Generating Facility has not failed an inspection required by the Utility. Evidence of approval by an electric code official includes a signed Certificate of Completion in the form of Attachment 4 or other inspector-provided documentation.

9. Additional review: If a Generating Facility has failed to meet one or more of the Level 2 screens, but the initial review indicates that additional review may enable the Utility to determine that the Generating Facility can be interconnected consistent with safety, reliability and power quality, the Utility shall offer to perform additional review. The Utility shall determine through additional review whether Minor System Modifications would enable the interconnection to be made consistent with safety, reliability and power quality. The Utility shall provide to the Applicant a non-binding, good faith estimate of the costs of such additional review, and/or such Minor System Modifications. The Utility shall undertake the additional review or Minor System Modifications only after the Applicant consents to pay for the review and/or modifications.

10. A Utility may elect to charge an application fee of $50 plus $1 per kW of Generating Capacity for Level 2 review.

(G) Level 3 Screening Criteria and Process for NonExporting Generating Facilities Not Greater than 20 MW:

Generating Capacity <= 1 MW no insurance

7. Additional protection equipment not included with the Interconnection Equipment Package may be required at a Utility's discretion as long as the performance of an Applicant's Generating Facility is not negatively impacted and the Applicant is not charged for any equipment that provides protection that is already provided by interconnection equipment Certified in accordance with Section C.

8. Metering: Net Metering for Solar, Wind, Hydropower and Fuel Cells as set forth in RCW 80.60: the Utility shall install, own and maintain a kilowatt-hour meter, or meters as the installation may determine, capable of registering the bi-directional flow of electricity at the point of common coupling at a level of accuracy that meets all applicable standards, regulations and statutes. The meter(s) may measure such parameters as time of delivery, power factor, voltage and such other parameters as the utility shall specify. The Applicant shall provide space for metering equipment. It will be the Applicant's responsibility to provide the current transformer enclosure (if required), meter socket(s) and junction box after the applicant has submitted drawings and equipment specifications for the utility approval. The Utility may approve other generating sources for net metering but is not required to do so. Net metering is available to generating facilities sized up to 100 kW only.

9. Production Metering: The Utility may require separate metering for production of electricity as required under applicable power purchase or credit programs. This meter will record all generation produced and may be billed separately from any net metering or customer usage metering. All costs associated with the installation of production metering will be paid by the Applicant.

10. Once an interconnection has been approved under these procedures, a Utility shall not require an Interconnection Customer to test its Generating Facility except that the Utility may require any manufacturerrecommended testing and:

i. For Levels 2 and 3, an annual test in which the Interconnection Customer's Generating Facility is disconnected from the Utility's equipment to ensure that the Generating Facility stops delivering power to the Electrical Distribution System.

For Level 4, all interconnection-related protective functions and associated batteries shall be periodically tested at intervals specified by the manufacturer, system integrator, or authority that has jurisdiction over the interconnection. Periodic test reports or a log for inspection shall be maintained.

11. A Utility shall have the right to inspect an Interconnection Customer's Generating Facility before and after interconnection approval is granted, at reasonable hours and with reasonable prior notice provided to the Interconnection Customer. If the Utility discovers an Interconnection Customer's Generating Facility is not in compliance with the requirements of IEEE Standard 1547, and the non-compliance adversely affects the safety or reliability of the electric system, the Utility may require disconnection of the Interconnection Customer's Generating Facility until the Generating Facility complies with IEEE Standard 1547.

12. The Interconnection Customer may disconnect the Generating Facility at any time without notice to the Utility and may terminate the Interconnection Agreement at any time with one day's notice to the Utility.

13. An Applicant may designate a representative to process an application on Applicant's behalf, and an Interconnection Customer may designate a representative to meet some or all of the Interconnection Customer's responsibilities under the Interconnection Agreement.

14. For a Generating Facility offsetting part or the entire load of a utility customer at a given site, that customer is the Interconnection Customer and that customer may assign its Interconnection Agreement to a subsequent occupant of the site. For a Generating Facility providing energy directly to a Utility, the Interconnection Customer is the owner of the Generating Facility and may assign its Interconnection Agreement to a subsequent owner of the Generating Facility. Assignment is only effective after the assignee provides written notice of the assignment to the Utility and agrees to accept the Interconnection Customer's responsibilities under the Interconnection Agreement.

15. Prior to any future modification or expansion of the Generating Facility, the Interconnection Customer will obtain Utility review and approval. The Utility reserves the right to require the Interconnection Customer, at the Interconnection Customer's expense, to provide corrections or additions to existing electrical devices in the event of modification of government or industry regulations and standards.

16. For the overall safety and protection of the utility system, RCW 80.60 currently limits interconnection of generation for net metering to 0.1% of the utility's peak demand during 1996. Additionally, interconnection of generating facilities to individual distribution feeders will be limited to 10% of the feeder's peak capacity. However, the Utility may, in its sole discretion, allow additional generation interconnection beyond these stated limits.

17. Reasonable Efforts: The Utility shall make reasonable efforts to meet all time frames provided in these procedures unless the Utility and the Applicant agree to a different schedule. If the Utility cannot meet a deadline provided herein, it shall notify the Applicant, explain the reason for the failure to meet the deadline, and provide an estimated time by which it will complete the applicable interconnection procedure in the process.

(K) Dispute Resolution:

1. For a dispute related to these rules, either Party may submit a written request to the other Party for an informal meeting by phone, electronic media, or in person to attempt to resolve the dispute. Following such a request, each Party shall make available a person with authority to resolve the dispute. A meeting shall be scheduled for at least one hour, but may be shorter at the option of the Party requesting the meeting. The meeting shall take place at a time and in a manner agreeable to the Party receiving the request within three business days of the Party's receipt of the request for a meeting. If a dispute involves technical issues, persons with sufficient technical expertise and familiarity with the issue in dispute from each Party shall also attend the informal meeting.

2. If an informal meeting of the Parties does not resolve a dispute, the Parties may mutually agree to further discussions or either Party may seek resolution of the dispute through the complaint or mediation procedures available in Seattle City Light's Departmental Policy and Procedures (DPP) Customer Dispute Resolution (DPP 500P III-425).

6.3.3 If an indemnified Party is entitled to indemnification under this Article as a result of a claim by a third party, the indemnifying Party shall, after reasonable notice from the indemnified Party, assume the deference of such claim. If the indemnifying Party fails, after notice and reasonable opportunity to proceed under this Article, to assume the defense of such claim, the indemnified Party may at the expense of the indemnifying Party contest, settle or consent to the entry of any judgment with respect to, or pay in full, such claim.

6.3.4 If the indemnifying Party is obligated to indemnify and hold the indemnified Party harmless under this Article, the amount owing to the indemnified Party shall be the amount of such indemnified Party's actual loss, net of any insurance or other recovery.

6.3.5 Promptly after receipt of any claim or notice of the commencement of any action or administrative or legal proceeding or investigation as to which the indemnity provided for in this Article may apply, the indemnified Party shall notify the indemnifying Party of such fact. Any failure of or delay in such notification shall not affect a Party's indemnification obligation unless such failure or delay is materially prejudicial to the indemnifying Party.

6.4 Consequential Damages
