10 sites with total ESS capacity of 18 MWh
Energy Storage, Utility Bill Optimization (UBO), Demand Response (DR)
600% savings increase compared to previous operating platform
The Fortune 100 retailer’s original system was experiencing negative monthly savings due to poor software performance from a prior provider, lack of utility integration, and the excess length of time to achieve value.
Stem took seamless control of the 10 sites spread across Southern California and provided a level of partnership and expertise that exceeded expectations. By helping improve the systems’ energy storage capabilities, UBO, and automated DR through our Athena platform, we help connect all 10 sites into a unified view for simplified clean energy management.
Stem improved short-term forecast accuracy with an enhanced balance between UBO and DR that showed improvements on day 1 of the billing cycle. The retailer was able to resolve previous metering issues with expert QA against utility meter data by working with Stem’s experts.
