Wind Generation Online Reporting

The Wind Generation Reporting System (WGRS) accepts generation data from wind plants operating in California. Reporting is required for wind projects rated 1 MW and larger in nameplate capacity. WGRS data is reported by wind plant operators. The online reporting form includes:

  • Verification of reporting party
  • Plant identification
  • Plant technology list
  • Energy production from plants rated at leastr 1 MW in capacity

As of January 1, 2022, plants rated at 1 MW but less than 10 MW must report annually but may report quarterly. Plants 10 MW and larger continue to report monthly data each quarter. Parties purchasing wind energy are no longer required to report.

Reporting in the online WGRS meets the requirements of 20 CCR 1304, Quarterly Fuels and Energy Reports (QFER) for power plants in California. Out-of-state wind plants file offline under 20 CCR 1304.

Reporting parties are encouraged to submit data through the online web portal in lieu of completing spreadsheets and PDF files. Operators may contact CEC staff to request online access: wgrshelp@energy.ca.gov

Plants rated 10 MW at larger must report data quarterly on the 15th day of the following months:

Quarter 1st 2nd 3rd 4th
Data period Jan - Mar Apr - Jun Jul - Sep Oct - Dec
Due date May. 15th Aug. 15th Nov. 15th Feb. 15th

Plants rated at 1 MW to less than 10 MW must report annually by February 15th for the preceding year, but they may file quarterly reports preceding the annual report.

If the 15th falls on a weekend or holiday, data is due on the next business day.

The WGRS is designed to collect non-confidential data. However, users may apply for confidential status for certain data. That status is granted after a formal application process and determination by the CEC Executive Director. Information on applying for that status and docketing is given here: http://www.energy.ca.gov/commission/chief_counsel/docket.html

Data must be reported by the due date, regardless of whether confidential status is requested. To apply for the status, complete the QFER forms offline and form CEC-13 offline. Then submit them to the docket by the due date.
