Ylem Secures Exclusive Battery Energy Storage Supply Agreement

Cutaway of battery energy storage system

Independent energy generation specialist, Ylem Energy Ltd, has announced that it has secured exclusive UK rights to large-scale battery energy storage systems (BESS) from a leading global provider, and will be showcasing the technology with a 1.2 MWh – 1MW battery energy storage system co-hosted at a UK-based landfill-gas generation site in the spring of 2019.

This agreement signifies the culmination of Ylem Energy’s investment in flexible generation technologies and complements the company’s move into owning and operating natural-gas powered peaking facilities at several sites across the UK.

Ian Gadsby, managing director of Ylem Energy Ltd, commented: “We’re delighted to be able to offer this cutting-edge storage technology into the UK market. For almost thirty years, we’ve operated our own fleet of smart energy generation systems that run on gaseous fuels and these storage systems provide an excellent opportunity for us to move further towards providing a range of technologies that meet the market conditions created by the modern-day grid operation and energy market.”

“These systems will be used in two ways, one will be to provide network resilience by coming online at short notice to meet the demands of the network – particularly where fluctuations in renewable generation from wind and solar have an impact. The other will be to help reduce our industrial and commercial clients’ reliance on costly peak-time energy tariffs as a wider package of measures.”

The 1.2 MWh 1MW pilot BESS project, which is planned to be commissioned in early 2019, will be located at a UK-based landfill site and provide flexibility services to the electricity grid, utilising energy generated from landfill gas.

Ylem Energy will be releasing further details of both the systems and this initial project in the coming months.



Ylem Energy Ltd is a leading independent power generation specialist, founded on its ability to generate energy from biogas fuels sourced from landfill and AD processes. Based in Salford, UK, the company draws upon its experience gained from nearly three decades of owning and operating reciprocating gaseous-fuelled generation systems throughout the world.

Whilst continuing its traditional activities with such systems, following significant investment in research and development, Ylem Energy has further extended its offering to encompass advanced flexible generation systems that enable better balancing of the grid and lower energy-intensive organisations’ reliance on importing costly peak power.
