Can solar-plus-storage systems be a cost-competitive source of energy in China?The decline in costs for solar power and storage systems offers opportunity for solar-plus-storage systems to serve as a cost-competitive source for the future energy system in China. The transportation, building, and industry sectors account, respectively, for 15.3, 18.3, and 66.3% of final energy consumption in China (5).
Will China achieve price parity to coal-fired power in 2021?About 78.6% (79.7 PWh) of China’s technical potential will realize price parity to coal-fired power in 2021, with price parity achieved nationwide by 2023. The cost advantage of solar PV allows for coupling with storage to generate cost-competitive and grid-compatible electricity.
What are energy storage power stations?On the grid side, specialized energy storage power stations will replace traditional thermal power plants to provide peak and frequency regulation functions and ensure the safety of the power grid operation.
How does grid optimization affect power generation and storage capacity potential?The power generation and storage capacity potential data used in the grid optimization model were aggregated from the grid cell to the regional power grid level with the constraints that the bus-bar price of the combined solar and storage system is equal to or lower than the coal power price.
