Which companies have built their own energy storage for peak load regulation

Why do we need independent energy storage stations?

Independent energy storage stations can meet the needs for energy storage by generators and for peak shaving and frequency regulation by power grids, expanding their channels for revenue generation and improving their economic potential. They will be an important direction for the development of energy storage stations in the future.

Why is peak-regulation important in power grids?

Peak-regulation in power grids needs to follow the fluctuation of renewable energy generation in addition to the variable load demands. Moreover, the wind power curve usually shows opposite increasing trend to the load curve, which requires more peak-regulation supply to guarantee the secure operation of power grids.

Do independent energy storage power stations lease capacity?

Independent energy storage stations lease capacity to wind power, PV, and other new energy stations. Capacity leasing is a stable source of income for owners of independent energy storage power stations. The capacity leased can be seen as energy storage capacity built for new energy projects.

How effective is peak-load regulation capacity planning?

Based on probabilistic production simulation, a novel calculation approach for peak-load regulation capacity was established in Jiang et al. (2017), which is still effective for peak-regulation capacity planning when some information of renewable energy and loads is absent.

Which energy resources are integrated into urban power grids?

In this paper, we consider various energy resources integrated into the urban power grids, such as thermal power including coal-fired and gas-fired power units, hydro power plants, nuclear power units, and renewable energy generators.

What is the implementation plan for the development of new energy storage?

In January 2022, the National Development and Reform Commission and the National Energy Administration jointly issued the Implementation Plan for the Development of New Energy Storage during the 14th Five-Year Plan Period, emphasizing the fundamental role of new energy storage technologies in a new power system.
