IID enters PPA for geothermal energy

California public power utility Imperial Irrigation District (IID) and Controlled Thermal Resources (CTR) on Jan. 16 announced the successful completion of a power purchase agreement for geothermal energy.

The agreement consists of a 25-year term to supply IID with 40 megawatts of geothermal energy from the Hell’s Kitchen facility, located at the bottom of the Salton Sea in the region’s globally recognized “Salton Sea Known Geothermal Resource Area.”

The geothermal power facility is expected to begin operating in 2023, which will occur during the development of CTR’s integrated direct lithium extraction and conversion facility.

The partnership helps IID meet its renewable energy goals, invest in local resources and support regional economic development. “IID has long advocated for the development of renewable energy resources at the Salton Sea, for what it can do for the Valley, and for what it can do for California,” said Henry Martinez, IID general manager. “The district is proud to secure this energy source for all benefits it can bring and we look forward to a strong, collaborative relationship with CTR moving forward.”

The renewables portfolio standard, established by the state, is one of California’s key programs for advancing renewable energy as it sets escalating renewable energy procurement requirements for load-serving entities.

In 2018, there were geothermal power plants in seven states, which produced about 16.7 billion kilowatt-hours, equal to 0.4% of total U.S. utility-scale electricity generation.
