Case Study: Electrodes Holdings achieves 30% greater energy savings with Stem's Athena software

Athena Improves Investor Storage Portfolio Performance by 30%

Electrodes Holdings, a joint venture focused on clean energy infrastructure, owns a 345 MWh commercial battery fleet across Southern California serving 86 sites and about 25 large commercial and municipal customers. When their original software provider exited the market, Electrodes ran a competitive RFP to find a replacement and selected Stem and its Athena energy-storage management software to optimize the portfolio and preserve utility and customer services.

Stem onboarded the fleet in roughly two months and deployed Athena for real-time optimization; after six months under Stem’s control, customers realized more than 30% greater monthly energy savings versus the prior provider. Stem also coordinated with customers and the utility during California rolling blackouts to help prevent outages while delivering virtual power plant capacity and improved economic returns for Electrodes.
