A large-scale Battery Energy Storage System (BESS) can engage in wholesale energy trading in several ways. The fundamental principle behind these methods is purchasing electricity at low prices and then selling it at higher prices.

How do battery storage units store electricity?

The battery storage units "physically" store the electricity during the period between purchase and sale. Arbitrage trading with a BESS takes advantage of price fluctuations in the power market. A typical marketplace for such arbitrage transactions is the spot market of an electricity exchange.

Why is a battery storage system a good choice?

Because they can react quickly to charging and discharging commands, battery storage systems are well-suited for providing services such as primary control reserve (PCR), also known as frequency containment reserve (FCR), in Europe. BESS can also participate in a capacity market by providing reliable reserve capacity for the grid.
