Peak Power Capacity
ICAES provides distributed capacity with zero emissions
The electric grid relies on hundreds of GW of peaking capacity that are called on during only a few peak hours each year. Some of the most polluting and highest marginal cost units, including simple-cycle peakers and liquid fuel generators, are used to supply this peak, reserve, and locational capacity. In 2010, ERCOT utilized its peak 10 GW of peaking capacity during only 4% of the year. Energy storage, charged with energy from efficient baseload plants or renewables, can be distributed throughout the grid to provide peak capacity. In this role, storage can displace some of the most inefficient generation assets while also increasing the utilization and value of existing assets.
A storage solution with a levelized cost of energy superior to gas peakers
Independent scalability of power and storage duration allows ICAES to provide an optimal solution for any energy or capacity application. With its inherently low capital cost, long lifetime, and high efficiency, ICAES can provide zero-emissions capacity and a superior levelized cost of energy (LCOE) compared to gas-powered "peaker" plants or conventional storage solutions such as batteries.
