EV Fleet Charging Depot
350kW / 800kWh
Energy Storage, Commercial EV Charging
With transportation now accounting for the largest share of U.S. greenhouse gas emissions, electric vehicles (EVs) will be key to the clean energy transition. Several states and the federal government have announced funding to increase the number of EVs on the road, and California requires all new passenger cars and trucks to be emissions-free by 2035.
A leading transportation logistics provider wanted to explore the benefits of battery energy storage at an EV fleet charging depot in California’s Inland Empire. Given the project’s potential benefits and the value of what could be learned, the company applied for and received pilot project funding from a state regulatory agency. It also assembled an all-star team including three Fortune 500 companies and Stem as its energy storage expert.
California regulations now require heavy-duty truck fleets to start transitioning to zero-emissions EVs in 2024. This has tremendous implications for companies like this client, who must rethink logistics around fleet charging and management and develop an appropriate investment strategy. Further, the project encountered headwinds when the original software provider had difficulty optimizing the battery to deliver value.
Because software issues had hampered the project, the company’s first priority was finding a proven software solution that could deliver superior EV charging results. And because this was the company’s first foray into leveraging energy storage for EV fleet charging, it needed an expert partner to provide a turnkey experience. With our extensive track record, service dedication, and best-in-class Athena™ software, Stem excelled across the board.
To maximize project revenues, Athena first modeled battery performance and charging behavior under a range of potential tariffs. Now Athena optimizes EV charging while providing a real-time window into system operations. Athena also ensures the project reduces GHG emissions in accordance with California’s Self-Generation Incentive Program (SGIP). Perhaps most importantly, the project is informing the company’s long-term fleetwide EV charging strategy.
