Small scale renewable power stations and the jobs they provide in the East are "at risk", according to an energy boss who is calling on the government to pledge further support before it is too late.
Melton Renewable Energy generates power by burning agricultural waste, such as poultry and straw, at its three plants in Thetford in Norfolk, Ely in Cambridgeshire - and Eye in Suffolk.
The company, like many others across the country, has long received financial support from the government as part of its Renewables Obligation scheme.
But there are currently no concrete plans to renew the contract when it runs out in April 2027.
Melton Renewable Energy chief executive Eddie Wilkinson said: "Without this support these stations are potentially not economically viable, so there is a lot at stake, and 150 jobs across the business are probably at risk."
