Peak regulation in the Northeast power grid is going from bad to worse. This stimulates the need to pumped-storage hydropower for its role in this respect. Based on the status of power sources and the load forecast in the system, the author puts forward a minimum construction scale of pumped-storage stations by the end of 2020 from technical feasibility, and an economic scale from economy. The analysis and comparison on the two schemes can be regarded as a reference for reasonably planning pumped-storage stations in the northeastern part of China.
