Stem executes on highest number of utility and grid calls in 2017

MILLBRAE, California. — August 30, 2017 — Stem, Inc. announced it has surpassed a number of company execution milestones made possible by its artificial intelligence (AI)-powered network of energy storage systems located at businesses and institutions throughout the U.S. Stem is building the world’s smartest and largest digitally-controlled network, now with more than 700 systems contracted or installed in 75 U.S. jurisdictions. Stem currently has 150 MWh of customer-sited systems across the U.S. ready to be aggregated. With its proprietary AI at the helm, the rapidly-expanding Stem network has successfully responded to more than 500 utility dispatch requests. In California, Stem has consistently offered stored energy from its network into the CAISO wholesale markets since 2015, including dispatch for seven grid areas during the unprecedented heat wave on June 19, 2017. Stem has dispatched aggregated customer-sited systems in 300 responses to the CAISO wholesale market in 2017 alone. Stem’s Athena^TM – the world’s most advanced energy intelligence—enables Stem to execute for its customers every day, optimizing the timing of energy use for businesses and institutions, and across the utilities that serve them. Shifting energy use away from the most expensive times for network members, while dispatching virtual power plants to strengthen the grid, is a complex problem best managed by AI. The growth of Stem’s network and successful execution of hundreds of grid service calls illustrates the unique value of real-time energy optimization using energy storage. Athena automatically links facilities into a powerful network that can instantly form virtual power plants to generate value for all members, in 350 MWh of local capacity and other grid services in Stem’s eight utility contracts in California, Hawaii, New York, and Texas. “When the grids need help, Stem’s energy superintelligenceTM steps up and responds in minutes by engaging our customer-sited resources, without any disruption to customer operations,” said John Carrington, CEO of Stem. “Athena makes distribution planning and local resource adequacy simple for utilities, while giving their customers a way to support grid reliability for their local communities.” Stem Inc., the global pioneer of energy storage-based real-time energy optimization for commercial and institutional customers, is backed by the industry’s largest project finance pool of over $500 million. In July 2017, Stem won the SEPA Power Player Award for Innovative Partner of the Year. With 350 MWh of utility-scale contracts and 500 utility dispatches to date, Stem is proving its advice to SEPA members of “innovate, execute, repeat.”
