Clugston Construction has announced it will extend a joint venture set up to build biomass energy facilities across the UK.
The firm set up the vehicle with French engineering firm CNIM (Constructions industrielles de la Méditerranée).
The two companies have already worked together on several energy schemes. They are building a biomass facility at Ridham Dock in Kent and five waste to energy plants around the country.
Clugston said the Ridham Dock plant will generate 188 million kilowatt hours of electricity a year, which could power 60,000 households.
Clugston Construction managing director Steve Radcliffe told Construction News in May that waste, energy and education projects now accounted for around 75 per cent of its turnover.
