Athena™ Smart Energy Software Increases Customer Savings by More Than 30%

MILLBRAE, Calif., April 14, 2021 (GLOBE NEWSWIRE) -- Stem, Inc. (“Stem” or the “Company”), a global leader in artificial intelligence (AI)-driven clean energy storage services, today announced it has completed six months of successful operation of the 345MWh energy storage portfolio owned by Electrodes Holdings LLC (“Electrodes”) which last year transferred portfolio control to Stem’s Athena™ smart energy software. Customers in the 86-site portfolio are now realizing more than 30% greater monthly energy savings on average compared to the previous software provider.

Within two months of being awarded the exclusive contract by Electrodes, Stem seamlessly onboarded to Athena management this portfolio that serves 25 large commercial and municipal customers in the Los Angeles area. The customers at these sites – ranging from office buildings, water treatment plants, university campuses, local government buildings, food processing plants, medical facilities, and retail superstores –now benefit from Athena’s intelligence and real-time decision-making to optimize energy storage systems and energy use. Stem has also delivered local controllable capacity to a Southern California investor-owned utility where the portfolio is based.

“This seamless portfolio transition is further proof of Stem's energy storage leadership and the effectiveness of our best-in-class Athena™ technology in delivering superior results for customers,” said Stem CEO John Carrington. “Our team’s technical and operational expertise allowed for a full, unimpeded, and highly-efficient changeover of these complex systems, ensuring maximum uptime for the customers while increasing returns for the system owner.”

“The more than 30% increase in savings performance we have achieved so far is a testament to Stem’s superior technology, leading customer service, and capabilities of our expert Programs team,” said Stem VP of Program Operations Julie Steury. “The efficient data transfer of an extensive energy storage portfolio along with hardware reconfigurations of 86 sites furthers our leading position in the critical California market and reflects the ongoing efforts of our data operations to successfully prioritize data integrity and transparency.”
