The construction cost of compressed air energy storage (CAES) is approximately $105 per kWh1. Additionally, the capital expenditure for CAES facilities is typically around $1,350 per kW, which influences the overall energy storage cost3. To achieve a 10% internal rate of return (IRR), a storage spread of 26 cents per kWh is required for a $1,350/kW CAES facility2. [pdf]
