Arizona utility makes biggest US bet yet on energy storage

Bloomberg

Arizona’s Pinnacle West Capital Corp. is kicking off the most ambitious deployment of energy storage ever announced by a US utility.
Pinnacle West’s Arizona Public Service plans to add 850 megawatts of battery storage and at least 100 megawatts of new solar power by 2025, according to a statement. The company did not say how much initiative would cost.
The move comes as Arizona regulators have placed a temporary moratorium on building natural gas-fired plants and as falling energy-storage prices have compel utilities to use batteries to extend output from solar farms after sundown.
