Power demand of energy storage power stations

Why is energy storage important?

Energy storage is one of the most important technologies and basic equipment supporting the construction of the future power system. It is also of great significance in promoting the consumption of renewable energy, guaranteeing the power supply and enhancing the safety of the power grid.

How can a power supply reduce energy storage demand?

The addition of power supplies with flexible adjustment ability, such as hydropower and thermal power, can improve the consumption rate and reduce the energy storage demand. 3.2 GW hydropower, 16 GW PV with 2 GW/4 h of energy storage, can achieve 4500 utilisation hours of DC and 90% PV power consumption rate as shown in Figure 7.

What is China's energy storage capacity?

China's energy storage has entered a period of rapid development. According to data from the Energy Storage Industry Alliance, in 2020–2023, China's installed power energy storage capacity grew from 35.6 to 86.5 GW.

How much electricity does a data center use?

According to Penn State’s Institute of Energy and the Environment, in 2023, artificial intelligence (AI) data centers consumed 4.4% of electricity in the United States, which could triple by 2028. By 2030-2035, data centers “could account for 20% of global electricity use, putting an immense strain on power grids.”

How will a pumped storage power plant contribute to the energy transition?

The company is making a significant contribution to the energy transition and is continuing its corporate transformation towards more renewable energy generation. By storing energy, the pumped storage power plant will contribute to greater security of supply in southern Germany.

Do data centers increase electricity demand?

Data centers are not alone in increasing electricity demand; the electrification of vehicles, heating systems, and industrial processes, pushed by the Biden administration, are also having an impact.
