E.ON, one of the world’s largest electric utility service providers, has connected a 10 MW battery to the Blackburn Meadows biomass plant near Sheffield, which is as of now feeding energy into the UK’s national grid. Through converting recycled waste wood into electricity, the plant produces enough power for around 40,000 homes.
Stored in four shipping containers, the 10 MW lithium-ion battery supports the grid by stabilizing the power supply. This works by balancing the power between supply and demand – this requires fast reaction times. Tests showed that E.ON’s battery system had a response time of under a second when the grid was either over- or under-supplied.
The changes in frequency through the addition of renewable energy sources has been a problem in the UK, so it “[…] is a milestone for E.ON in the new energy world and an important recognition of the enormous potential for battery solutions in the UK,” said David Topping, Director of Business Heat and Power Solutions at E.ON.
Leon Walker, Commercial Development Manager at National Grid, added: “Using battery storage is a significant development for managing the national grid. It’s an ultra-fast way of keeping electricity supply and demand balanced. Over four years we estimate that this service will save the system operator around £200m. This is good news for consumers who benefit from our cost efficiencies, and paves the way for battery technology to establish itself as an important component of our energy system.”
