In 5 Years, Batteries Will Blanket The U.S., Duke Executive Says

Five years. That’s how soon batteries can be expected to sprout all over the electric grid as utilities and homeowners drop in on a wave of falling prices, a Duke Energy executive said in Chicago Thursday.

“There’s going to be a lot of excitement around batteries in the next five years. And I would say that the country will get blanketed with projects,” said Spencer Hanes, a managing director of business development with the Charlotte, North Carolina-based utility.

“With the way that the cost curves are coming down it’s a big opportunity for all of us to deliver what customers want.”

What customers want, it seems, is solar-plus-storage. They want it enough that homeowners are propping up the battery business even before it can make them money, said Adam Gerza, chief operating officer of the solar software firm Energy Toolbase.

“The momentums and drivers behind actual installed solar-storage projects are things like backup power and energy independence, and there’s a little bit of a screw-my-utility kind of attitude,” Gerza said, sitting alongside Hanes on a panel Thursday at Solar Power Midwest in Chicago. “In one word, it’s almost like emotion.”

Most homeowner projects don’t yet make economic sense, Gerza said. “There’s actually a pretty big subset of people that still want to do it anyways. So that’s happening, and frankly we need those creative use cases because purely from an ROI (return-on-investment) perspective it doesn’t make sense just yet.”

But sometimes it does make sense, according to Troy Miller, the director of grid solutions for S&C electric, a manufacturer of grid components.

“I think there are cases where it does make economic sense today, and they’re only going to grow,” Miller said, predicting market increases over the next five years in all three sectors: residential, commercial and industrial.

Prices have dropped from about $800 per kilowatt hour in 2012 to $281 in 2016, Hanes said, and are expected to continue to fall by 9 percent per year.
