Male Wind and Solar Energy Storage Power Station

What is the energy scale of energy storage power stations?

The energy scale of energy storage power station is expanding. By the end of 2022, it has reached 18.27 GWh, with an average charging and discharging time of 2.1 hours. Influenced by local policies that “new energy power stations must be equipped with energy storage”, storage in power supply-side is the largest, more than 50%.

What is the energy supply system at Xiaoma Park?

The park lacks original energy supply equipment but has an established transmission line infrastructure. An integrated regional energy system is constructed by adding 700 MW photovoltaic generators, 1000 MW wind turbines, 300 MW pumped storage units, 100 MW energy storage stations, and 200 MW hydrogen storage facilities for hybrid storage.

What is China's energy storage industry?

1. Pumped Storage:dominant in power storage ◼ 2. New Energy Storage (mainly Electrochemical Energy Storage): grow fast with a great prospect China's pumped storage power stations grow steadily, from 18.38 GW in 2011 to 31.49 GW in 2020, with an average annual growth rate of 6.2%.

How do pumped storage power stations recover operating costs?

Pumped storage power stations recover the operating costs of pump and generation through the electricity energy tariff. The capacity tariff reflects the value of the auxiliary services provided by the pumped storage power station, such as frequency regulation, voltage regulation, system standby and black start, etc.
