Our base case for Compressed Air Energy Storage costs require a 26c/kWh storage spread to generate a 10% IRR at a $1,350/kW CAES facility, with 63% round-trip efficiency, charging and discharging 365 days per year. Our numbers are based on top-down project data and bottom up calculations, both for CAES capex (in $/kW) and CAES efficiency (in
China is currently in the early stage of commercializing energy storage. As of 2017, the cumulative installed capacity of energy storage in China was 28.9 GW [5], accounting for only 1.6% of the total power generating capacity (1777 GW [6]), which is still far below the goal set by the State Grid of China (i.e., 4%–5% by 2020) [7].
