Peel Environmental, a subsidiary of Peel Holdings, has had inquiries from companies in the UK, Europe and America about its incinerator plan in Ince, Cheshire.
The Government's Department of Energy and Climate Change gave the green light in August for a power plant, capable of turning 600,000 tonnes of waste each year into electricity and heat, to be built.
The £254m plans involve building an incinerator to recycle waste and generate electricity on a 250-acre site alongside the Manchester Ship Canal in Ince Marshes, near Helsby.
Peel is currently refining costs and hopes to make a decision by the end of the year on which company will operate the incinerator, with talks being held with both investors and operators. The site will also incinerate commercial and industrial waste, rather than the household waste which was originally applied for, Peel has confirmed.
A public inquiry was held over seven weeks in the spring of last year as Peel sought to overturn Cheshire council's decision to reject its planning applications for the controversial scheme in 2006.
Local opposition by residents claimed it would threaten their health and quality of life.
Peel argued that the facility would help minimise landfill and the need to use fossil fuels to generate power.
The waste, which would have otherwise gone to landfill, will instead be used to generate electricity to power a new Resource Recovery Park. Excess electricity will also be exported to the National Grid.
The project is scheduled to be complete in 2012.
