Overall battery skip rates have improved since the end of 2023 - falling from above 90% to 76% in August. A skip is when a more expensive action is taken instead of an available, cheaper battery action. This can happen for a number of reasons, including technical limitations in the control room.
The solution lies in alternative energy sources like battery energy storage systems (BESS). Battery energy storage is an evolving market, continually adapting and innovating in response to a changing energy landscape and technological advancements. The industry introduced codes and regulations only a few years ago and it is crucial to
Optimising battery performance is important if energy storage is to be efficient. Batteries should be charged and discharged at the correct times, minimising loss of energy and extending battery life. Optimal energy storage performance helps to keep the grid stable and reliable and helps to integrate renewable energy solutions.
