MILWAUKEE — As Americans increasingly clamor for renewable energy sources to supplement utility power grids, Glendale-based Johnson Controls is
exploring a possible new product line: energy storage hubs.

“We have a building efficiency business, we have a battery business and we have automotive,” said Brian Dillard, executive director of systems electronics
and integration for Johnson Controls. “Energy storage kind of fits somewhere in between buildings and batteries for us. It’s a new area that we’re focused on.”

But Dillard cautioned that for Johnson Controls to move forward, “there must be a reward” to offset the risk of investing in new technology.
