Energy Storage

Energy storage systems are an important element in the energy transition, as they can store energy when too much is produced from renewables, and make it available when needed. For example, overproduction from solar power stations at midday can be stored for use in the evening once the sun has set. Battery storage systems can adapt to almost any circumstance, since they can be set up in almost any location, and are highly flexible in terms of size.

Energy storage

Why do we need it?

Energy storage will fundamentally underpin the energy transition, enabling the shift to renewable zero carbon electricity system. In order to the deliver both UK Government’s  “British Energy Security Strategy” and RWE’s climate neutral , targets by 2040, both large scale renewable generation and flexible low carbon generation solutions will be required. Energy storage assets, such as batteries, can provide a valuable contribution to UK energy security.

In an energy market with high volumes of renewable energy, energy storage can help smooth the variable nature of renewable generation such as wind and solar to more closely meet the country’s electricity demand needs. It can also be used to help manage electricity network stability and power flows, such as where there are grid constraints.

UK government has also indicated that mechanisms should be anticipated before 2024 to incentivise development of longer duration energy storage projects.

Technology

Energy can be stored in many forms. For short duration storage (up to circa 4hrs), Battery Energy Storage Systems (BESS) offer a good fit for electricity system and market requirements. Batteries are rechargeable systems that store energy from the grid and provide energy to the grid as required. They contain advanced control technology that regular batteries do not, to support electricity network and generation constraints.

RWE’s ambitions

RWE is one of the UK’s largest generators with around 10GW of generation capacity from both onshore and offshore wind, hydro, gas and biomass. The company has a target to achieve net zero emissions by 2040 and to this end is investing €55 billion between 2024 and 2030 to grow its green core business, globally, with £15 billion earmarked for the UK. RWE is currently targeting global energy storage capacity of 3GW by 2030.
