The fee-based charging network will consist of about 200 publicly available fast-charging stations, installed in the San Francisco Bay area, the San Joaquin Valley, the Los Angeles Basin and San Diego County.

Additionally, NRG’s EV infrastructure commitment will include the wiring for about 10,000 individual charging stations located at homes, offices, multifamily communities, schools and hospitals located across the State.

NRG chief executive officer David Crane said with this agreement, the people of California will gain a charging infrastructure ready to support their current and future fleet of electric vehicles.

"And we will be helping the State meet its clean car goals as embodied by its Zero Emission Vehicle mandate," Crane said.

The agreement calls for a network that will bring a minimum of 200 direct current fast chargers to the state, and about $100m in infrastructure investment over four years, and $20m in cash to go to the California Public Utility Commission.

It also calls for a minimum of 10,000 parking spaces retrofitted with wiring necessary to charge EVs at multifamily buildings, large worksites and civic sites such as universities and hospitals.
