Maximizing merchant revenue for battery energy storage systems (BESS) is complex. With an ever-evolving landscape affecting BESS participation in the ERCOT wholesale market, this paper assesses how Stem’s Athena® platform would have performed managing bid optimization for a sample of ERCOT BESS in 2022.

In this whitepaper, our experts share their findings and insights using real-world data from ERCOT to compare different optimization scenarios, including actual revenue attainment for operational assets. The stochastic price forecasting and advanced optimization capabilities of Stem’s AI-driven Athena platform enabled an average revenue uplift of 28% over incumbent operators for the analyzed assets. 

The whitepaper also provides key takeaways for optimizing storage operations in merchant markets like ERCOT. Stem invites industry stakeholders and interested parties to further explore the scope and takeaways from this analysis.
