Energy storage power generation transmission and electricity use

Why is energy storage important in a power system?

Energy storage is a potential substitute for, or complement to, almost every aspect of a power system. It can improve generation, transmission, and demand flexibility. Storage should be co-optimized with clean generation, transmission systems, and strategies to reward consumers for making their electricity use more flexible.

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.

Why are energy storage technologies important?

Energy storage technologies have been recognized as an important component of future power systems due to their capacity for enhancing the electricity grid's flexibility, reliability, and efficiency. They are accepted as a key answer to numerous challenges facing power markets, including decarbonization, price volatility, and supply security.

What can energy storage be a substitute for?

Energy storage is a potential substitute for, or complement to, almost every aspect of a power system, including generation, transmission, and demand flexibility. Storage should be co-optimized with clean generation, transmission systems, and strategies to reward consumers for making their electricity use more flexible.

What role does energy storage play in the future?

As carbon neutrality and cleaner energy transitions advance globally, more of the future's electricity will come from renewable energy sources. The higher the proportion of renewable energy sources, the more prominent the role of energy storage. A 100% PV power supply system is analysed as an example.

Why is electricity storage important?

In the electricity market, global and continuing goals are CO 2 reduction and more effi cient and reliable electricity supply and use. The IEC is convinced that electrical energy storage will be indispensable to reaching these public policy goals.
