The company also announced $707 million in financing for the 250-megawatt Sierra Estrella Energy Storage facility in Avondale, Arizona, making it the largest standalone energy storage project financing.
"The financing commitments announced today cover five projects totaling 1,040 megawatts of capacity," Plus Power said in a news release.
The announcement also includes 700 megawatts of additional battery plant building on the ERCOT grid in Texas, which will be operational by next summer.
Three new battery plants will begin operation by next summer to cater to increased demand amid increasingly extreme temperatures.
