South East Water signs green energy deal with EDF power solutions UK

9th September 2026

Over a third of South East Water’s energy requirements will be sourced by renewable energy, thanks to the signing of its largest UK corporate Power Purchase Agreement (cPPA) with EDF power solutions UK.

The new partnership is a key step in South East Water’s commitment to be a low carbon sustainable business and will see the drinking water only company sourcing the green, renewable energy from 102MW Stranoch onshore wind farm in Dumfries and Galloway, Scotland. The 20-turbine site is currently under construction and due to be operational next year.

The site will provide South East Water with enough energy to power 33 average-sized water treatment works for a year.

Oliver Martin, Strategy & Regulation Director at South East Water, said: “We are delighted to be working in partnership with EDF power solutions UK to take a proportion of the energy generated from Stranoch wind farm in Dumfries and Galloway.

“Renewable energy sources are a crucial part of the transition to a cleaner, safer, and more sustainable world and clean energy development is vital for combating climate change.

“This is a key step on our net zero journey and moves us closer to our target of becoming operational net zero carbon.”

Anthony MacDonald, Head of Origination at EDF power solutions UK commented: “We are pleased to be working with South East Water to help the business on its journey to reducing its carbon emissions and powering around 33 water treatment works annually from our Stranoch wind farm.

“This is one of three corporate Power Purchase Agreements (cPPAs) set up to take a proportion of the energy from Stranoch and is a key step to decarbonising businesses across the UK.”

Tom Abbott, PPA Director, EDF Business & Wholesale, said: “This agreement demonstrates how CPPAs can help organisations access renewable energy at scale while supporting their long-term sustainability ambitions. Through our shaping, balancing and sleeving services, we will ensure the power generated by Stranoch wind farm is seamlessly integrated into South East Water’s supply agreement, helping the drinking water company maximise the value of renewable electricity despite the intermittent nature of wind generation.

“We are delighted to support South East Water on its net zero journey with a reliable, long-term route to sourcing low carbon energy.”
