Sainsbury’s signs PPA with Capital Dynamics’ Longhill Burn Wind Farm in Scotland


LONDON, 31 October 2023 – As part of its commitment to become Net Zero in its own operations by 2035, Sainsbury’s has agreed to buy 100% of the energy that will be generated by the Longhill Burn Wind Farm (“Longhill”) in Scotland by signing a Purchase Power Agreement (“PPA”) with Capital Dynamics, an independent global private asset management firm and one of the world’s leading renewable energy investment managers.

Longhill will provide up to 50 megawatts (MW) of renewable wind energy to power Sainsbury’s stores, offices and depots nationwide and give a major boost to the retailer’s ambition to become Net Zero. Over the course of a full year, they are expected to produce around 150,000 megawatt hours (MWh) of electricity, which is enough to power over 2.8 million standard LED lightbulbs continuously[1] or provide electricity for around 55,000 average UK homes[2]. When all the turbines are operating at maximum capacity, together they will provide enough electricity to supply up to 33% of Sainsbury’s total electricity needs.

Located in West Lothian, it features a total of eight state-of-the-art wind turbines, designed and delivered by Siemens Gamesa. The blades measure a colossal 76 metres in length and the turbines stand at over 200m tall at their highest point[3]. Each turbine provides a maximum output of between 6-6.4MW, making them the largest and most powerful onshore wind turbines available in the UK.

The project was developed by Energiekontor AG, and once operational will benefit from Capital Dynamics’ and Energiekontor’s longstanding operations management experience.

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. Now it’s completed, Longhill Burn Wind Farm can begin to realise its full potential, helping us take another massive step towards reducing our reliance on carbon.

Sainsbury’s was the first UK retailer to start directly purchasing wind power for use in its estate back in 2008. Our commitment to the future of Longhill Burn Wind Farms, which both enabled its construction and guaranteed its long-term viability, builds on our proven track record of investing in sustainable technologies.” 

Barney Coles, Managing Director, Co-head of Clean Energy at Capital Dynamics, said: “We thank Sainsbury’s for joining Capital Dynamics as a key partner in developing the Longhill Burn Wind Farm, which adds a critical source of clean, low-cost energy to the UK’s power generation fleet. Strong commitments to renewable energy from companies like Sainsbury’s are essential to helping the UK lead the global energy transition and meet its emission targets. We look forward to working with Sainsbury’s and other multi-national corporations to develop affordable, subsidy-free projects that will accelerate private sector participation in the energy transition."

Peter Szabo, CEO of Energiekontor AG, said: “At Energiekontor, we are proud to be part of the energy transition in the UK. Being pioneers in the renewable energy sector for more than 30 years, we have been the first to realize a wind farm free of any public subsidies in the UK in 2018 and continue to do so ever since. Now, with the Longhill Burn Wind Farm, we are once again setting new standards, as the wind farm will deploy the so far largest onshore wind turbines in the UK.”
