Economic Optimization of 3 MWh Battery

2015

In 2015 while at the National Renewable Energy Laboratory, Dr. Simpkins led the analysis of a 1 MW – 3 MWh battery for San Diego Gas & Electric. The primary application of the battery was to perform PV smoothing on a feeder that was saturated with solar. The analysis determined the maximum annual revenue that could be derived by participating in the CAISO ancillary service markets and performing energy arbitrage at the nodal LMPs when the battery was not needed for PV smoothing.
