What is the Wind Energy Co-Metering Program?
California Public Utilities Code 2827.8 governs net energy metering (NEM) service for certain large wind generating customers. Such customers are referred to as Wind Energy Co-Metering (or NEMW) customers. Instead of receiving credit based on the total energy charge like solar or smaller wind NEM customers, the credit for generation exported to the grid is based only on the generation component of the energy charge.
You must take service as a NEMW customer if:
- You have wind generating facilities greater than 50 kW and less than or equal to 1,000 kW in size.
- You request a Net Energy Metering (NEM) rate schedule.
- You request Time-of-Use (TOU) as your OAS (otherwise applicable rate schedule) for Net Energy Metering.
- You meet all other requirements for a Net Energy Metering rate under the NEM tariff.
Note: Customers who have a hybrid system consisting of both a NEM eligible solar generating facility and a NEM wind energy co-metering eligible generating facility, and whose total generating facility size is less than 1,000 kW, must be served under the terms of the Wind Energy Co-Metering section.
Special Metering Arrangements: Because NEMW customer-generators are required to take service on a TOU OAS, they must have TOU metering. That metering will consist of one (when possible) or more TOU meters, capable of separately measuring (a) the electricity supplied by PG&E to the customer and (b) the electricity generated by the customer and fed back to the electric grid.
How do I apply?
The application materials for Wind Energy Co-Metering are the same as those for NEMEXP:
| Item Requested | Why We Need It |
|---|---|
| Application Form (Form 79-974) | Important Information about your current account and generation project. |
| Supplemental Application Form (Form 79-998) | Additional information about your requested rate, your meter accessibility and your disconnect switch. |
| Interconnection Agreement (form 79-978, revised 11-06-03) | Legal contract between PG&E and the customer outlining each party’s responsibilities. |
| Single Line Diagram | Simple diagram for technical review. |
| Declarations page of Property Insurance | To provide PG&E with information about your level of insurance coverage (if any). |
| Signed-off Building Permit | To signal that the project is finished and approved by the local building authority |
| Authorization to Receive Customer Information or Act on a Customer’s Behalf (PDF, 20 KB) | Required only if customer desires third party (such as a contractor) to act on the customer’s behalf and receive private customer information (note that this form does not give the third party the ability to sign contracts for the customer). |

What equipment is required to interconnect?
All systems must have a visible accessible lockable disconnect switch and all meters must be accessible for the PG&E meter reader to read your recorded usage and exports as well. Other requirements for interconnection are provided in Electric Rule 21.
How does Wind Energy Co-Metering Billing work?
The credit for generation of electricity provided to PG&E by a Wind Energy Co-Metering customer is based on the generation component of the energy charge from the customer’s otherwise applicable rate schedule (OAS).
The charge for electricity supplied to the Wind Energy Co-Metering customer by PG&E is the same as that in the customer’s OAS.
In the event that at the end of each 12-month period, on a kilowatt-hour basis over all TOU periods, the electricity the customer fed back to PG&E is less than or equal to the electricity supplied to the customer by PG&E, the energy the customer fed back to PG&E is valued at the generation component of the energy charge in the customer’s OAS.
In the event that at the end of each 12-month period, on a kilowatt-hour basis over all TOU periods, the electricity fed back to the electric grid by the eligible customer-generator exceeds the electricity supplied to the eligible customer-generator by PG&E, the eligible customer-generator is a Wind Energy Co-Metering producer and no payment is made for this excess generation as provided in the NEM tariff.
