For the developer of a utility-scale solar+storage facility, Brattle provided a third-party validation of facility revenues to support the client’s due diligence efforts. We utilized bSTORE to evaluate wholesale energy market revenues, accounting for the ability of storage to store excess solar generation that otherwise would have been “clipped” by the undersized inverter and strategically discharge the stored energy into the wholesale market to maximize revenues. We estimated revenues through 2040 under a variety of future scenarios, accounting for real-world complications, such as the effect of imperfect foresight when operating the facility in day-ahead and real-time wholesale power markets.
