Ancillary Services
Ancillary Services refers to the extra support services that energy storage systems provide to maintain a stable and reliable power grid. Think of these as backup services that help keep the electricity network running smoothly, like helping to maintain steady voltage levels or providing emergency power when needed. These services are becoming increasingly important as more renewable energy sources like wind and solar are added to the power grid. Energy storage companies can earn additional revenue by offering these support services to utility companies and grid operators.
