Stem has announced new collaborations with Urban Energy Solutions and SunGreen Systems to use Stem’s artificial intelligence (AI), Athena, in intelligent solar+storage solutions in Arizona and California. These projects represent Stem’s entry into a sixth U.S. state and the continued high growth of solar+storage momentum across the country.
AI-powered energy storage is enabling the rise of “intelligent” solar. Stem’s Athena AI increases the economic value of a solar generation system by using stored solar power during the customer’s peak, and enabling the customer to navigate changing electricity rates long into the future.
In 2017, Stem began working with Urban Energy Solutions, a national renewable energy developer and EPC provider with one of the largest renewable portfolios in Arizona, on a first collaborative solar+storage installation in Tucson, Arizona, for Amphitheater School District. The AI-powered storage system anticipates the site’s energy needs, helping to avoid a “demand charge” that can comprise nearly fifty percent of a site’s monthly bill. The Stem system also responds to fluctuations in solar generation, lowering the demand peaks that can occur when solar production suddenly drops due to cloud cover.
“We appreciate Stem’s focus, like ours, on enhancing customer control. With tools like intelligent storage and solar, every commercial and industrial facility manager can maximize their reliance on renewable energy while reducing their energy costs,” stated John Mitman, Director of Engineering and Development at Urban Energy Solutions. “Stem’s artificial intelligence helps our customers ‘future-proof’ their solar investments and energy management decisions with automated savings.”
In California, Stem is also partnering with SunGreen Systems, a Pasadena, California-based provider of customized commercial solar, LED lighting, and energy storage. Stem and SunGreen are focused on solar+storage solutions for commercial and industrial customers in the highly-congested West Los Angeles basin, where transmission constraints hinder capacity for Southern California Edison.
“Intelligent energy storage is necessary for California to reach its 100% renewable energy goal, and combining AI-driven storage and solar just makes sense. It allows business owners to cut their high demand charges while giving them energy independence at reasonable rates,” said John Hoffman, CEO of SunGreen Systems.
“The energy markets are changing; customers want more control over their energy sources and energy spend as electric rates change,” said John Carrington, CEO of Stem. “Stem is committed to our growing partner network, and we are excited to work with Urban Energy Solutions and SunGreen Systems on intelligent solar + storage solutions that maximize economic opportunities for their customers.”
Stem is expanding its Stem Partner Network to top-tier solar developers looking to Stem’s artificial intelligence leadership and energy storage deployment experience, and Stem’s solar+storage business comprises a growing percentage of its 900+ energy storage systems under management across six states and three countries (United States, Japan and Canada). Stem’s $650 million in project financing is the largest among its peers, an additional advantage to solar providers.
