APS switching to solar+batteries for peaker plants

June 2019—Arizona Public Service has been criticized for its luke-warm support for rooftop solar. But they do see a business model in utility-scale solar plus batteries.

APS has traditionally relied on natural gas for peaker plant services. Today’s announcement signals a new direction for the utility, according to Jeff Burke, director of resource management at APS.

“What we’re really excited about,” he said, “is how we’re transitioning to more of a solar with storage [model] to meet some of our peaking needs.”
