Our battery systems provide a front line of defence for balancing the electricity network.

What is Battery Storage?.

What is Battery Storage?

Batteries are a fundamental energy storage technology used across a range of applications. The lithium-ion batteries found in smartphones, laptops and electric vehicles are the most widely known. However, on a larger scale, Battery Energy Storage Systems (BESS) provide services to electricity networks.

Batteries perform two functions for the electricity network. They use electricity to charge when there is surplus energy or low demand and they also transfer energy back to the grid in times of high demand. As renewable energy generation increases, BESS are becoming an increasingly important tool to provide services to the grid and to large scale electricity users.

How we use Batteries.

How we use Batteries

Our battery systems are designed to deliver an efficient and reliable service that can adapt to various market conditions. The BESS we develop can provide super-fast, sub second responses to demand and generation changes. These are typically used to provide short duration balancing services, such as frequency response, to maintain the grid frequency at 50Hz. They have capacity to operate at full power for up to a few hours.

Mid duration

Pumped hydro

Pumped hydro-electric storage is a proven zero carbon technology for medium-duration energy storage. Although its expansion is limited by geography, it represents a significant source of the UK’s storage capacity.

Long duration


Green hydrogen is produced using electrolysis technology that’s powered by renewable energy. It can be used for flexible thermal generation and long-duration storage which will be crucial for balancing the grid and reaching net zero.
