Should shared energy storage power stations be allocated?

This allocation method, although straightforward for the overall system to distribute the costs associated with the shared energy storage power station to each renewable energy power station involved, does not take into account the practical use rates of the shared energy storage services and may appear unjust to stakeholders.

What is an energy storage system?

An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.

What is a capacity charge?

One significant yet often misunderstood component is the capacity charge. As electricity systems become more complex with the integration of renewable energy and demand-side management, capacity charges play a crucial role in ensuring grid reliability and economic efficiency.

Why do power plants have capacity charges?

The rationale behind capacity charges stems from the need to incentivize both generators and consumers to maintain a balanced and reliable electricity grid. Power plants must be available and ready to produce energy when demand spikes, even if they run infrequently or at partial capacity.
