The 3 MW battery system at the ground of Premier League club Arsenal in north London will be able to run the 60,000-seat stadium for the entire 90 minutes of a match. A further 1MW of storage to be added next summer.
Arsenal managing director Vinai Venkatesham 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 organization.”
The system is also intended to operate as support for the wider UK grid. It be automatically traded and optimized by Open Energi in response to market signals and has already secured a frequency response contract from National Grid.
Open Energi’s Dynamic Demand 2.0 platform will operate the system to allow Arsenal to avoid peak power prices, buying electricity when it is cheap and storing it for use when prices are high, and also respond to market signals from National Grid.
Open Energi commercial director David Hill explained: “Operating a battery across multiple timeframes and markets requires careful management and constant evaluation of the cost-benefit of each action. Dynamic Demand 2.0 uses machine learning to automate and optimize battery performance second-by-second, delivering savings for businesses and clean, reliable flexibility to the grid.”
He said the Arsenal project “is a great example of how energy storage can enable a more sustainable energy future and put end users in control of how, when and from where they consume electricity”.
The storage system has been installed by Pivot Power, which will manage it for 15 years. Chief executive Matt Allen said: “Battery storage is an incredibly flexible asset and we’re delighted to be working with Open Energi to ensure Arsenal receive the maximum benefits from this system.”
In 2016, Arsenal became the first Premier League club to switch to 100 per cent green electricity when it signed a deal with Octopus Energy – its energy comes from a network of solar farms and anaerobic digestion plants.
Allen added: “Arsenal is showing how football clubs and other big power users can save money and support the UK’s climate change and clean air targets. 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.”
Arsenal has installed LED floodlights which use 30 per cent less electricity than conventional lights. The stadium recycles 80 per cent of match day waste, with all food waste sent to an anaerobic digestion plant where it is turned into energy to supply the club.
