Plans for two nationally significant 60MW energy-from-waste plants have been bolstered by proposed changes to the Renewables Obligation Order 2009. KTI Energy said it was moving towards planning consent for two 500,000 tonne a year combined heat and power plants.
The plants, which KTI hopes to have operational by 2013, are planned for sites near Crawley, Sussex and Basildon, Essex.
Company managing director Bill Temple-Pediani said project finance was being finalised.
ROO 2009 proposals [to be finalised in April 2009] will undoubtedly make the projects more attractive to investors, he said.
Under the ROO 2009 proposals, power stations will be have the flexibility to co-fire SRF and virgin biomass for the first time. It gives the operator an alternative if Renewable Obligation Certificated fuel supplies stop unexpectedly.
Changes to the feedstock will not penalise the whole plant, the fuel changes will just be taken into account, he said.
Waste feedstock, in the form of solid recovered fuel, will come from domestic and commercial sources. The standard project model will take SRF from two waste processors, one domestic waste processor and one commercial waste processor.
According to the model, the commercial plant will be built next to the CHP facility, while the domestic facility will be external. Temple-Pediani said discussions were underway with large waste management contractors about who will take on the franchise for commercial processing.
Domestic treatment plants which could supply SRF have been proposed by Biffa at Warnham and Essex County Council at Burnt Mills.
Power generated at the Crawley plant will supply Crawley and Gatwick Airport and discussions are underway with developer Crest Nicholson and West Sussex County Council to supply a planned estate for 2,500 homes.
The second site near Basildon will power a large industrial estate and discussions are underway with Essex County Council to supply SRF from its proposed plant.
If successful, this model could be used to build a CHP plant in London.
