Water company Pennon has won a contract relating to the Keppel Seghers Energy from Waste (EfW) plant in Runcorn, Cheshire.Pennon subsidiary Viridor Waste Management has been awarded the engineering procurement and construction gig for the second phase of the plant's development.The Phase II project requires capital investment of around £160m from available internal funds as required, for a 375,000 tonnes per annum capacity plant. This is in addition to the £34m of advanced and shared works required for both Phase I and Phase II, announced in April 2009. "Construction of Phase II will be coordinated with ongoing work on Phase I which permits significant cost savings. It will enable Phase II to come on stream by 2014/2015 by which time large scale energy from waste facilities will be cost competitive against landfill with landfill tax by then being £80 per tonne," explained Colin Drummond, chief executive of Viridor.
