Waste-to-energy power plant

B&W Vølund, working with UK construction partner, Interserve Construction, was awarded the EPC/turnkey contract for the waste-to-energy plant in Peterborough, UK. The facility is provided by Viridor under a 30-year contract signed with Peterborough City Council. The plant was handed over to Viridor in December 2015, on time and within budget.

From waste to green electricity

The plant processes 85,000 tonnes of residual household, commercial and industrial waste from the local area. It generates 7.25 MW of green energy, corresponding to the electrical consumption of 15,000 households.

Before the construction of the plant, 94 % of Peterborough’s waste was not recycled and left in the landfill. Now the waste is recovered as electricity and with guaranteed low emission levels. The power plant is contributing to Peterborough Council’s Blue Sky project to provide sustainable energy in a smart city environment.

First DynaGrate® in the UK

In the fall of 2014, UK’s first ever DynaGrate® was installed in the Peterborough facility. DynaGrate® is B&W Vølund’s state-of-the art combustion grate which is one of the most advanced combustion grates on the waste-to-energy market today. Furthermore, the DynaGrate® has low operating and maintenance costs. Operational experience has shown that the O&M costs are lower compared to other types of grates. 

Peterborough City Council’s Director of Resources, John Harrison, recommends the small, yet highly efficient, energy recovery facility solution to other city councils (2014):

”This plant will produce in excess of 7 MW of electricity. That is a major power generator. It will be one of the most efficient plants in the whole of UK. That is why it was chosen. I think this is the technology that the UK should follow. It is an exemplar project.”
