Enbala raised at least $12 million in Series B financing led by ABB Technology Ventures, the Swiss grid giant's venture arm. ABB just picked Enbala’s technology to build out its distributed energy resource management system (that's DERMS) -- a hot commodity among forward-looking utilities, particularly those in regions with lots of customer-sited rooftop PV. Enbala has raised about $42 million from investors including GE Ventures, Chrysalix and Obvious Ventures. Enbala's competition on the DERMS front includes grid giants developing their own platforms, and startups like Advanced Microgrid Solutions, Blue Pillar, AutoGrid, Opus One, Power Analytics, Spirae, Smarter Grid Solutions, and the recently acquired Viridity Energy.  

Fresh from the GTM Research analyst dungeon:
