ERCOT: Battery Storage Revenue Summary

Ascend performed an assessment of ERCOT battery storage revenues for the first half of 2023.  The data, extracted from publicly accessible Security Constrained Economic Dispatch (SCED) data on the ERCOT website, presented a clear picture of the distribution of wholesale energy and ancillary revenues accrued by different projects normalized by project capacity. Ascend’s analysis highlights the performance in June 2023, which stood out as the highest revenue-generating month of the first half of the year. In addition, the analysis revealed that the introduction of ERCOT's latest ancillary product, the ERCOT Contingency Reserve Service (ECRS), contributed a substantial 26% to the total earnings for June.  

The results displayed a large spread in the distribution of normalized revenues, with revenues averaging $26,000 per MW-month (inclusive of ECRS) in June.  The data indicates that although June was the highest revenue generating month in ERCOT this year, there were batteries reporting negative and barely positive revenues. For example, while some projects, such as Key Capture Energy’s Endurance Park battery, raked in a maximum of $44,000 per MW-month, the lowest project realized a revenue of negative $12,000/MW in June.  

Operators looking to engage in this market asked Ascend to gauge their standing against the market average and competitors. As a result of these discussions with customers, Ascend Analytics conducted a benchmarking exercise in which Ascend’s simulated bidding strategies were compared against the ERCOT SCED data (see Figure 1).
