MILLBRAE, Calif. – April 30, 2019 – Boston Properties, Inc. and Stem, Inc., the global leader in artificial intelligence (AI)-powered energy storage, have commenced operation of the largest indoor energy storage system in the U.S., at the Colorado Center in downtown Santa Monica.

The Colorado Center is a 1.1 million square foot property in the heart of the “Silicon Beach” of Santa Monica. Stem has installed a 3.9 megawatt-hour (MWh) Athena^TM-powered storage system to lower energy bills for eight buildings on the property and increase the sustainability of the local grid. 

Stem’s platform, Athena, the first artificial intelligence for customer-sited energy storage, performs real-time energy optimization to offer automated savings when lowering tenants’ energy bills, while also providing additional capacity to the local utility, Southern California Edison, in the highly-congested West Los Angeles Basin.

“Energy storage will play an increasingly important role in peak demand charge management and the transition to a cleaner, more resilient grid,” said Ben Myers, Director of Sustainability at Boston Properties. “Stem’s turnkey energy storage solution complements our efforts to deliver sustainable real estate solutions that benefit our tenants, shareholders, and the communities we serve.”

The system at Boston Properties’ Colorado Center joins the world’s largest digitally-connected energy storage network, where Stem will use the systems when idle as flexible assets that smooth variable renewable energy on the electric distribution grid. In fact, the installation is located near other Stem systems on the same portion of the Santa Monica distribution grid, enhancing grid reliability for the “Silicon Beach” neighborhood.

“Boston Properties is a recognized sustainability leader in the commercial real estate space,” said John Carrington, CEO of Stem, Inc. “We are proud to contribute our energy superintelligence to their environmental sustainability, community relations, and corporate financial performance goals.”
