Wilton 10

A Biomass Waste EFW facility Wilton 10 is based upon the co-firing of Wood Waste, virgin wood, forestry processing rejects and energy crops to generate 30MWe and 10MWth of energy for use in the grid and the adjacent Sembcorp site, as an ancillary operation to their 197MW Wilton Power Station.

Summary

A Biomass Waste EFW facility Wilton 10 is based upon the co-firing of Wood Waste, virgin wood, forestry processing rejects and energy crops to generate 30MWe and 10MWth of energy for use in the grid and the adjacent Sembcorp site, as an ancillary operation to their 197MW Wilton Power Station. The plant consumes up to 300,000 tonnes per year of material, of which around 80,000 tonnes is Wood Waste supplied by UK Waste Wood Recycling, a subsidiary of Enva, from a nearby separate site.

The Wilton 10 facility was developed by Sembcorp Energy UK and was operational in the autumn of 2007 and at the time was the first large scale biomass power station to be built. It is located in Teeside on the Wilton International Industrial Estate and is discrete from Wilton 11 which is a Residual Waste EFW project.

Plant

Built under an EPC contract with Foster wheeler for a reported $55m (excluding the turbine and power island supplied by Siemens), the standard combustion technology is based on a Fluidised Bed system.

Annual Sustainability Tonnage Input/Fuel

The tonnage received by the plant in the most recent Annual Sustainability Report and for the previous 3 years for 2020/21 was reported by Ofgem as below:

Waste Tonnage, By Origin

The table shows a list of the Waste for the Permit NP3838LV, that has arrived into sites as reported to the Regulator and then publicised in their reported statistics. The Data was last updated on October 2023. The total reported tonnage arriving at the site was: 30,918.48t. Where this tonnage exceeds that reported in year of the corresponding annual report, this may be due to the following reasons:

• Tonnage may have been received but not incinerated, i.e. the material is held pending incineration (the operator return to the EA reports as received whereas the annual report focuses on when the waste is incinerated.)
• Material may have been received into the site but treated in some other way than incineration.
• Material may have been received on the but transferred out of site for disposal/treatment at another site rather than incineration on the site.

The Wood Waste is exclusively supplied by UK Waste Wood Recycling (previously owned by Hadfield, acquired by Enva in 2018), which sources much of the Wood Waste from Waste Disposal Authorities.
