CITY OF GLENDALE, CALIFORNIA
REPORT TO THE CITY COUNCIL
AGENDA ITEM
Report: Glendale Water and Power (GWP) Power Source Disclosure Report and Power Content Label for Calendar Year 2023.
1. Motion to Note and File the GWP Power Disclosure Report and Power Content Label for Calendar Year 2023.
COUNCIL ACTION
Item Type: Action Item
Approved for November 19, 2024 calendar
EXECUTIVE SUMMARY
Each year, the City Council reviews and files the Power Source Disclosure (PSD) Report and the accompanying Power Content Label (PCL), which are generated as part of the California Energy Commission’s (CEC) Power Source Disclosure program. The PCL offers a comprehensive breakdown of GWP’s power supply sources serving its customers and how these compare to California’s "grid average" power mix. The data is inventoried and independently verified, ensuring transparency in GWP’s power supply portfolio. The PCL is published each fall, covering the previous calendar year, and is presented to the City Council.
RECOMMENDATION
Note and file this GWP PSD Report and associated PCL for Calendar Year 2023.
ANALYSIS
The annual PSD Report, which is attached to this Report as Exhibit A, and associated PCL, which is attached to this Report as Exhibit B, is prepared using the same Open Access Technology International (OATI) electronic tagging information (e-tags), Western Renewable Energy Generation Information System (WREGIS) renewable energy credits (RECs), metered generation, and load data that is obtained by GWP staff for financial settlements. The data collected is also used for Renewable Portfolio Standard (RPS) and Greenhouse Gas (GHG) tracking and reporting purposes.
On June 21, 2024, GWP submitted the annual PSD report for calendar year 2023 to the CEC. A revised PSD report (Exhibit A) was re-submitted to the CEC on September 11, 2024, after all the MWh were verified.

The 2023 annual PSD and PCL reports have been verified by an independent auditor for accuracy and completeness and it was concluded that all procedures were performed in accordance with CEC regulations.
Glendale’s 2023 Power Content Label
Percentages are provided annually by the CEC based on the electricity sold to California consumers during the identified year. The City of Glendale 2023 PCL was posted on the GWP website on October 1, 2024.
https://www.glendaleca.gov/government/departments/glendale-water-and-power/about- us/power-content-label.
The PCL will also be mailed to each utility customer as a bill insert from October 23, 2024 through December 23, 2024.
In 2023, GWP’s renewable percentage was 35.3%, which maintains our position from 2022 (35.2%). GWP remains impacted by a delay in commercial operation date (COD) and an underproduction of various renewable energy resources such as geothermal plants Star Peak and Whitegrass.

In 2023, GWP observed an increase in the use of unspecified power sources due to the ongoing demolition and new construction of the Grayson Power Plant. As the plant undergoes construction, the temporary reduction in local generation capacity has demanded greater reliance on external unspecified power to meet the community’s energy needs. In contrast, during 2022, the Grayson Power Plant was still operational, providing consistent energy output that significantly reduced the need for unspecified power. The increase of unspecified power will continue until the completion of the new Scholl Canyon Biogas Project and new Grayson Power Plant facility, which are currently scheduled for summer of 2025 and summer of 2026, respectively.
A total of 798 unbundled RECs generated from GWP’s incentivized photovoltaic (PV) rooftop solar installations were retired for Renewable Portfolio Standard compliance during this reporting period, representing 0.1% of GWP’s retail sales.
The City of Glendale has continued to make significant strides in achieving clean energy goals, reaching an impressive 55.1% clean energy generation in 2023. This achievement is largely due to our Renewable Portfolio Standards (RPS) sources, as well as clean energy from large hydroelectric and nuclear power facilities. By maintaining this commitment to clean power, the City of Glendale continues to exceed California’s clean energy mandates, consistently providing its customers with clean energy.
