US solar-plus-storage developer Primergy has signed a “long-term” power purchase agreement (PPA) with California community energy supplier San Diego Community Power (SDCP).

The deal will see SDCP acquire power generated by Primergy’s 400MWac Purple Sage Energy Center, a project currently under development in the neighbouring state of Nevada, near the California border. The project also consists of a 1.6GWh battery energy storage system (BESS), and Primergy expects to commission the facility in 2027.

The project is not Primergy’s first in the space, following its work on its US$1.2 billion Gemini solar-plus-storage project, also in Nevada. The developer has worked with a number of key industry players on the project, including major solar manufacturer Maxeon and lithium-ion battery manufacturer CATL, and its work on the project, which boasts a power generation capacity of 690MWac and a BESS capacity of 1.4GWh, could help with the development of its latest Nevada project.

The deal with SDCP is also notable, as it will aid the initiative in meeting its growing energy demand, with the SDCP expanding its customer base to close to a million people by the end of 2023. The SDCP is a Community Choice Aggregator (CCA), a programme where local governments can manage and distribute power to local citizens, currently in operation in ten states in the US.
