EDP Renewables North America (EDPRNA) has inaugurated the 200MW Scarlet II solar energy park (Scarlet II) in Fresno County in the US state of California.

The project follows the launch of Scarlet I, which consists of 200MW of solar and a 40MW/160 megawatt hours (MWh) battery energy storage system (BESS), which came online in 2024.

The second phase of the Scarlet solar energy park includes a co-located 150MW/600MWh BESS, significantly increasing the project’s resilience.

The full output of the 200MW solar energy is secured through a 15-year virtual power purchase agreement (VPPA).

The resource adequacy associated with the 150MW BESS is contracted under long-term resource adequacy (RA) agreements with Ava Community Energy and San José Clean Energy.

California’s Resource Adequacy Program guarantees that load-serving entities (LSEs) have enough power capacity to cater the demand and ensure grid reliability.

With the expansion into the Central Valley, EDPRNA now has more than 1.1GW of operational solar, wind and storage projects throughout California.

Scarlet II will generate enough energy to power the equivalent of 68,000 California homes annually, and will contribute millions to local governments through tax payments, and stimulate local economies.

The build has created 140 jobs and accounts for more than $1,537,000 in spending within the state.

In line with its environmental stewardship commitment under the Close the Loop Program, EDPRNA recycled more than 1,700 tonnes of material during construction, exceeding 60% of total reported construction material recycled through partnerships with EPC Rosendin and materials recyclers.

In California, EDPRNA has an operational footprint of 1,138MW spread across multiple projects, including two phases of the Scarlet solar energy park and three phases of the Rising Tree wind Farm in Kern County.

EDP Renewables North America CEO Sandhya Ganapathy stated: “After our successful launch of Scarlet I, we are thrilled to add Scarlet II to our portfolio and build on our record of delivering energy reliability and resiliency for Fresno County and the Golden State.

“We are proud that our meaningful partnerships and investments in the community helped generate strong local support for the expansion of Scarlet solar energy park.”
