1. Generator Interconnection applications are required for all Generating Facilities and Energy Storage Devices (batteries) that will interconnect and operate in parallel with utility provided electric service.

2. Submission of this Generator Interconnection Application begins Hetch Hetchy Power’s assessment of electrical system needs and capacity related to the proposed interconnection request. It does not guarantee that SFPUC will be able to accommodate the request or provide Net Energy Metering service.

3. For detailed rules governing Electric Service and Customer-owned Generators see “City and County of San Francisco, San Francisco Public Utilities Commission, Power Enterprise, Rules and Regulations Governing Electric Services" which can be found at sfpuc.org/rates.

Part I - Select Program

A. Distribution System Mechanism Type

SFPUC provides electric service to customers through two Distribution System mechanisms. Depending upon which mechanism applies to the service account and the generators point of interconnection, the interconnection application and agreement will be handled as described below. Select the service account Distribution mechanism type:

Third-party owned Distribution System - Examples: City Hall, San Francisco Municipal Transportation Agency, In-fill affordable housing facilities: Customers must submit this application and the SFPUC will then help facilitate the Wholesale Distribution Tariff (WDT) interconnection review process performed by PG&E on the customer's behalf to obtain the required PG&E Generator Interconnection Agreement.SFPUC owned Distribution System - Examples: Hunters Point Shipyard, Potrero HOPE, Treasure Island, Yerba Buena Island, Bay Corridor Transmission and Distribution accounts: Customers must submit this application and the SFPUC will then work with the customer directly to facilitate a required SFPUC Generator Interconnection Agreement.

B. Application Type

Select the application type that best describes your situation:

New self-generating facility interconnection at existing SFPUC service siteNew self-generating facility interconnection at future SFPUC service siteModification to existing generating facility (adding/replacing/removing equipment)

C. Net Energy Metering

Indicate the type of NEM Program under which you plan to participate: (Note: Participation in NEM is not required, but to apply for NEM, you must submit a separate NEM application in addition to this Interconnection application. Visit the Hetch Hetchy Power Net Energy Metering Programs for more information: sfpuc.org/nem.

NEM CCSF (Available only to Municipal Customers connected through PG&E’s third-party owned electric distribution system. Examples include City Hall, San Francisco Municipal Transportation Agency, and In-fill affordable housing facilities.) NEM-SFPUC (Traditional NEM, Available to customers on Hetch Hetchy Power Owned distribution, such as Hunters Point Shipyard, Potrero HOPE, Treasure Island, Yerba Buena Island, Bay Corridor Transmission and Distribution accounts.) NEM-ShaRE (A virtual style NEM, that shares output from one generator to multiple accounts, Available to customers on Hetch Hetchy Power Owned distribution, such as Hunters Point Shipyard, Potrero HOPE, Treasure Island, Yerba Buena Island, Bay Corridor Transmission and Distribution accounts.)

Part III – Description of the Generating Facility

A. Variances from PG&E's Distribution Interconnection Handbook (DIH) and Greenbook Requirements

Where Hetch Hetchy Power utilizes PG&E's electric distribution network to provide electricity to customers, generating facilities must meet PG&E requirements documented in the Distribution Interconnection Handbook (DIH) and the Greenbook . Where Hetch Hetchy Power owns or controls the Distribution network to provide electricity to the customer, customer's generating facilities must comply fully with the requirements of the City and County of San Francisco, San Francisco Public Utilities Commission, Power Enterprise, Rules and Regulations Governing Electric Services" which can be found at sfpuc.org/rates, This generally requires the customer generating facility to meet or exceed PG&E requirements in the DIH and Greenbook. Please review these documents and indicate whether:

The facility meets both the DIH and Greenbook requirements and does not require a variance requestThe facility does not meet all the DIH and Greenbook requirements and requires a variance request

If variance request is required, please include the following documentation:
(1) description of the proposal for which a variance is required;
(2) copy of the single line diagram or electrical drawings, including equipment, location, and/or distances for the proposed work;
(3) color photos of the proposed site;
(4) manufacturer specification drawings for unapproved equipment that the customer is requesting an approval

D. Initial Operation Date

In-Service Date (mm/dd/yyyy)

Trial Operation (Inspection) Date (mm/dd/yyyy)

Planned Initial Date of Operation (mm/dd/yyyy)

Are there any funding or other deadlines for which Permission To Operate (PTO) is needed?

The SFPUC is unable to make any guarantees as to achieving PTO deadlines, particularly where Points of Interconnection are on the PG&E distribution grid. It is the Applicant’s responsibility to provide ample time for Interconnection document processing and Inspection scheduling.

E. Warranty Information

Note: You must select "Yes" to at least one of the questions. If you select "No" to both questions, the application will be rejected.

Has a warranty of at least 10 years been provided on all equipment and its installation?

YesNo

Has a 10-year service warranty or executed agreement ensuring proper maintenance and continued system performance been provided?

YesNo
