ENEL Acquires Energy Storage Software and Microgrid Project Developer Demand Energy

Enel Green Power has acquired a 100 percent stake in Demand Energy Networks, Inc. (“Demand Energy”), a Washington-based provider of intelligent software and energy storage systems.

Demand Energy has taken a central role in microgrid projects in New York, Costa Rica, and elsewhere with their ‘Distributed Energy Network Optimization System’ (DEN.OS).  DEN.OS is an intelligent software controls platform that enables real-time optimization of energy management and revolutionizes the way electricity is generated, stored and consumed.  The platform positions the company to partner or take the lead on energy storage microgrids, which is quickly becoming a majority of all microgrids..

Through this transaction we will be able to greatly strengthen our position in the growing battery storage market with a complementary partner and innovator.

By combining our global presence and expertise in systems integration withDemand Energy’s software and established product offering, we will expand the development of renewables and storage both in the US and globally, delivering a clean, reliable, high-tech and cost-effective energy solution.
