Arsenal Football Club (www.arsenal.com) has become the first Premier League team to install a battery storage system (BSS) at its ground.

In a joint announcement last week, Arsenal and London-based Pivot Power said that the 3MW system could store enough energy to run the Emirates Stadium for the entirety of a match.

Initially, only 2MW of its capacity will be used, with the remainder switched on next summer.

Arsenal has worked in partnership with renewable-energy firm Octopus Energy since 2016 and now uses 100% ‘clean’ electricity from a network of solar farms and anaerobic-digestion plants.

Vinai Venkatesham, Arsenal’s managing director, said: “This is a big step forwards for us in being efficient with energy usage, and it builds on our work in reducing our carbon footprint as an organisation.

“We have been powered by ‘green energy’ since 2016 — thanks to Octopus Energy — and the battery storage system will support our efforts further.”

In addition to its renewable-energy consumption, Arsenal is looking to reduce its carbon footprint in a number of ways.

At the Emirates Stadium, 80% of match-day waste is recycled, with all food waste diverted to an anaerobic-digestion plant, where it is converted into energy.

While sources such as solar power are renewable, they do not provide a constant stream of power. Battery systems allow companies and other organisations to store energy when it is available and then use it when required.

Matt Allen, Pivot Power CEO, said: “Batteries are central to creating a cost-effective low-carbon economy, and we are keen to help government, local authorities and businesses seize the opportunities they offer.”
