As part of Severn Trent’s latest trading update, Severn Trent Green Power is announcing the acquisition of Andigestion Limited. This is subject to clearance by the Competition and Markets Authority (CMA). 

Until then, ST Green Power and Andigestion remain strictly as two separate companies.¹

The acquisition will bring an additional 45 GWh of energy generation output every year and will give ST Green Power new reach into Southwest England covering major cities like Bristol, Gloucester and Exeter, in turn helping more businesses to process and recycle their food waste into renewable energy. 

Christer Stoyell, Managing Director of Green Power, said: “Having delivered double-digit growth in renewable energy generation since 2020, today’s announcement marks the start of a very exciting next chapter for all of us at Green Power. Following CMA clearance, we look forward to welcoming our new Andigestion colleagues and working with them to develop new growth opportunities and provide our award-winning services to even more households and businesses – powering the UK towards a cleaner and more sustainable future.”

Peter Prior, Summerleaze Group Executive Chairman, said: “The Summerleaze Group has been at the forefront of the development of the UK's anaerobic digestion industry since 2005. Since then, with the help of its dedicated team of employees, Andigestion has grown into a profitable business which the directors now consider would benefit from being incorporated into a wider renewable energy portfolio, of which it will form a valuable part. We believe that Severn Trent Green Power is ideally placed to deliver that.”

ST Green Power is one of the largest producers of renewable energy from food waste in the country. A quarter of all UK households’ collected food waste are sent to their anaerobic digestion facilities for processing and recycling into clean energy that can power 60,000 homes. 

In addition, the acquisition will help bolster the energy resilience of Severn Trent, ST Green Power’s parent company, and will play a key role in delivering its Triple Carbon Pledge (net zero emissions, 100% energy from renewable sources, and 100% electric fleet) by 2030.
