The project sites are selected to solve for issues the grid faces such as frequency events and intermittency
events prompted by the increase in renewable generation. In addition, the batteries serve the system
at times that there is peak demand patterns and the grid may be facing thermal or renewable curtailments.
The projects use 2-hour lithiumion batteries. The technology was selected for its high cycle life and asset longevity,
giving the assets the ability to respond to dispatch requests in less than a second. The system will provide the ability for the batteries
to service the real-time marketplace as well as the ancillary service markets within ERCOT. The initial projects are in the
West Zone and there are plans in place to expand this footprint across other ERCOT load zones.
