DETROIT—General Motors Co. is expanding beyond car making, with plans to offer energy storage and management services to residential and commercial customers through its new GM Energy unit in a move that puts it in even greater competition with Tesla Inc.
GM Energy will bundle the existing Ultium Charge 360 public charging service with two new units, Ultium Home and Ultium Commercial, that will offer stationary storage batteries, as well as solar panels and hydrogen fuel cells, the company said on Tuesday.
