Arizona Public Service (APS) has announced a plan to make solar energy dispatchable into the evening using batteries, calling for the deployment of 850MW of energy storage by 2025.
The installation will be used to provide “critical peaking capacity” and “increased” grid reliability. AES will provide a system with a four-hour duration based on Fluence’s Advancion platform. It will be leased under a 20-year contract with AES the owner and operator of the project.
Arizona utility Salt River Project (SRP) has followed up the recent completion of a 10MW battery storage system at a solar farm by beginning work on its first standalone grid-scale battery energy storage project.
NextEra Energy Resources and utility Salt River Project (SRP) have completed the Pinal Central Solar Energy Center in Arizona, an integrated PV plant equipped with a battery system that will store energy and allow SRP to provide power to its customers.
Vertically-integrated solar energy company First Solar will be involved in the first megawatt-scale battery system announced in Arizona since it was revealed the state could put a 3,000MW energy storage deployment target in place.
A 3,000MW energy storage target, proposed in Arizona as part of a grid modernisation policy, recognises the role of the technology in reducing the need for fossil fuels to stabilise the grid, a consultant has said.
Median bids received by US utility Xcel Energy in a solicitation for energy resources for energy storage paired with solar came in at US$9 per megawatt lower than the previously observed record.
Sunverge Energy has signed off on deals with three electric utilities in Arizona, Florida and Vermont that will expand the company’s customer base for its storage system and Virtual Power Plant (VPP) platform.
In its home territory of Germany, energy storage provider Sonnen is making a play to replace utilities, but its business models in the US will instead emphasise cooperation with existing energy suppliers.
