Advanced energy storage, including solutions based on lithium-ion battery technology, are technically and economically superior to traditional generation-based mechanisms used for supply of ancillary services. Energy storage can also help accelerate the adoption of renewable energy by compensating for the variabilty of wind and solar. Energy storage makes these sources more predictable, allowing them to be more seamlessly integrated with the existing power grid.
