What is China's pumped-storage project?

It is the first of China's mixed pumped-storage project in national large-scale clean energy bases to break ground and the highest-altitude large-scale pumped-storage project in the country. Built at 3,000 meters above sea level, the power plant is designed to be installed with four 300,000-kilowatt reversible generator units.

What will the new mixed pumped-storage power station do?

Given its unique pumping and power generation capacity, the new mixed pumped-storage power station with an installed capacity of 1.2 million kW is expected to support new energy-based power generation and will help improve new energy consumption.

What is the current energy storage capacity of a pumped hydro power plant?

The DOE data is current as of February 2020 (Sandia 2020). Pumped hydro makes up 152 GW or 96% of worldwide energy storage capacity operating today. Of the remaining 4% of capacity, the largest technology shares are molten salt (33%) and lithium-ion batteries (25%).

What is a pumped storage hydroelectric project?

Pumped storage hydroelectric projects have been providing energy storage capacity and transmission grid ancillary benefits in the United States and Europe since the 1920s (Energy Storage Association n.d.). 2 percent of the capacity of the electrical system (U.S. Energy Information Administration 2020).

Is Lianghekou a'regulator' of new energy?

Home to rich new energy resources, the Lianghekou region has more than 20 million kW of wind and solar energy. However, power generation based on such new energy is intermittent, volatile and random. The Lianghekou Hydropower Station has been playing a role as a "regulator" of about 3.5 million kW of new energy.

How much does pumped storage cost?

In addition, pumped storage offers potentially other benefits to the electric power grid, but with the potential environmental consequences as discussed above. PSH systems have a wide cost range of $1,500/kW–$5,100/kW. The lower component of this range originates from the projected cost for a PSH project at Eagle Mountain in Southern California.
