Sonnedix has commenced operations at the 40MW Sonnedix Gammaton solar photovoltaic project in North Devon, its first large-scale solar plant in the UK.
The company said the project will generate 42GWh of renewable electricity annually, enough to power more than 11,000 households and avoid 15,700 tonnes of CO2e emissions each year.
It added that Sonnedix Gammaton secured a contract under the UK’s AR4 and AR5 Contracts for Difference allocation rounds, supporting investment in low-cost renewable energy.
Sonnedix noted the project is located adjacent to Alverdiscott power station, offering strong grid infrastructure and potential for future co-location opportunities.
The company said it expects to bring 300MW of large-scale projects into operation in the UK during the first half of 2026, including the 120MW Cowley Complex in County Durham and Sonnedix Gonerby in Lincolnshire.
“Achieving COD at Sonnedix Gammaton is an important milestone in the development of our UK portfolio,” said Axel Thiemann, ceo of Sonnedix.
“Not only will it be a significant contributor of clean electricity, helping the UK meet its decarbonisation and energy security goals, but this site also enhances our ability to deliver customers with reliable, consistently affordable energy.”
“At Sonnedix Gammaton, responsible development has been prioritised by thoughtfully integrating renewable energy generation with existing agricultural practices,” said Rafael Curado-Molini Alvarez, head of growth for the UK.
“Throughout the process, Sonnedix has worked closely with local stakeholders to ensure the project delivers lasting environmental benefits while making a positive and sustainable contribution to the surrounding community.”
