SYNOPSIS

The importance and attractiveness of energy storage as an integral part of the electric power system is receiving increasing attention by a wide range of stakeholders including electric utilities, end-users, grid system operators and regulators. Energy storage provides a wide range of beneficial services and cost savings to generators, TSOs, DSOs and consumers, who are deploying storage technologies for a number of different purposes.

Energy storage is starting to play a broader role in energy markets, moving from niche uses such as grid balancing to broader ones such as replacing conventional power generators for reliability, providing power quality improvement capabilities and providing back-up power to prevent interruptions and voltage sags. It is also accelerating renewable energy deployment as it can provide some of the flexibility that future electric power systems will need to accommodate the fluctuating availability to solar and wind energy.

Energy storage will play a crucial role in enabling the next phase of the energy transition. Along with boosting solar and wind power generation, it will allow sharp decarbonisation in key segments of the energy market.
