Glendale City Council adopts resolution to enter geothermal power sales deals

The Glendale, Calif., City Council adopted a resolution on Feb. 25 to enter into a set of long-term power sales agreements with the Southern California Public Power Authority (SCPPA) to purchase geothermal energy.

The projects, Whitegrass No.1 Geothermal and Star Peak Geothermal, under the management of Open Mountain Energy, LLC located in Nevada, will start on April 2020 and April 2021, respectively. The two projects combined will bring 15.5 megawatts of renewable energy to Glendale and Glendale Water & Power customers and will move Glendale significantly further towards meeting the state of California’s mandates of S.B. 100 (100 percent carbon-free electricity by 2045).

The geothermal projects will equate to an estimated 11% increase in Glendale Water & Power’s Renewable Portfolio Standard. The zero-carbon energy provided to the public power utility’s customers will reduce carbon emissions by 52,600 metric tons per year, Glendale Water & Power noted.

Glendale Water & Power said that geothermal energy is consistent and has a high capacity factor at approximately 90%, as compared with the lower capacity factors of intermittent resources like solar and wind, which are at 25% and 34% respectively.

In December, the utility announced that it entered into a 25-year power sales agreement with SCPPA for a 12.5% share of renewable solar energy, battery storage, and environmental attributes from the Eland 1 Solar and Storage Center in Kern County, Calif.

 Glendale is a member of SCPPA, a Joint Powers Authority created in 1980 for the purpose of providing joint planning, financing, construction, and operation of transmission and generation projects. It is comprised of eleven municipal utilities and one irrigation district.
