SECTION 3 PUMPED HYDRO ENERGY STORAGE
Long-term development plan for pumped hydro storage
In order to promote the rapid development of pumped storage, meet the needs of new power system construction and large-scale and high proportion of new energy development, and help achieve the goal of carbon peak and carbon neutrality, the National Energy Administration recently issued the "Pumped Storage Medium and Long Term Development Plan (2021-2035)" (hereinafter referred to as the Plan).

Differences between pumped hydro storage and wind power
It has been globally acknowledged that energy storage will be a key element in the future for renewable energy (RE) systems. Recent studies about using energy storages for achieving high RE penetration hav. Can pumped storage hydropower be used in areas that are not practical?YouTube [pdf][FAQS about Differences between pumped hydro storage and wind power]
Pumped hydro storage space
Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. [pdf]
Wallis and Futuna spinning wheel energy storage
Flywheel energy storage (FES) works by accelerating a rotor () to a very high speed and maintaining the energy in the system as . When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of ; adding energy to the system correspondingly results in an increase in the speed of th.

Water storage energy
A water battery — also known as a pumped storage hydropower system — is an energy storage and generation method that runs on water. When excess electricity is available, water is pumped to an upper reservoir, where it stands by like a bank of potential energy until there’s a surge in demand. [pdf]
