Charging Ahead: The future of battery energy storage

Energy storage technologies are a vital part of electricity systems that are becoming increasingly dominated by intermittent renewables. Batteries are one of the most mature of these technologies and have strong cost and technical advantages, minus their present energy capacity limits. Systems installed ‘behind-the-meter’ (BTM) also offer support services directly and indirectly to the grid. Modular technology batteries can be utilised rapidly, with failures or maintenance likely to cause less system-wide disruption. Battery energy storage systems (BESS) generate returns in four ways: energy...
