Sainsbury’s has announced the completion of a new wind farm in Scotland which will add up to 50 megawatts of electrical capacity to the grid in the form of renewable energy. The new wind farm will be used to power Sainsbury’s stores, offices and depots nationwide, boosting the retailer’s ambition to become net zero in its own operations by 2035. Construction on the Longhill Burn wind farm in Scotland began in 2021 when Sainsbury’s signed an agreement with Capital Dynamics to buy 100% of the electricity it generates. Over the next 15 years, Sainsbury’s says it will invest millions of pounds in the renewable energy produced by the wind farm. Located in West Lothian – around fifteen miles outside of Edinburgh – the farm features eight wind turbines designed and delivered by Spanish-German wind engineering company Siemens Gamesa. The blades measure 76 metres in length and the turbines stand at over 200 metres tall at their highest point. Each turbine provides a maximum output of between 6-6.4MW, which Sainsbury's says makes them the "largest and most powerful onshore wind turbines available in the UK". When all the turbines are operating at maximum capacity, they will supply up to 33% of Sainsbury’s total electricity needs. Over the course of a full year, they are expected to produce around 150,000 megawatt hours of electricity, which is enough to provide electricity for around 55,000 average UK homes Longhill Burn is the seventh wind farm from which Sainsbury’s now buys 100% of the energy generated and an eighth site is expected to go live next year. Patrick Dunne, Sainsbury’s director of property, procurement and EV ventures, said “We’re very proud to be investing in this state-of-the-art, sustainable source of new wind power, featuring the largest, most cutting-edge onshore turbines available in the UK.” “Our commitment to the future of Longhill Burn Wind Farm... builds on our proven track record of investing in sustainable technologies.” The project was developed in partnership with Energiekontor AG, which managed the construction of the wind farm and will oversee its day-to-day operations and maintenance. Longhill Burn will benefit from Capital Dynamics’ and Energiekontor’s longstanding operations management experience. This is the latest in a cohort of sustainability initiatives made by the UK supermarket giant, in September Sainsbury’s unveiled the “UK’s largest” lower carbon beef range, and announced that it was investing an additional £6 million annually into its dairy farmers. In July the retailer announced its new steak packaging would save 10 million plastic pieces annually. In April, Sainsbury’s went trayless on whole chickens and earlier this year removed plastic bags from its entire banana range, while in February it removed all traditional plastic tray packaging across its entire beef mince range.
