Slough Heat and Power Plant


Summary

A Biomass Waste Combined Heat and Power(CHP) EfW facility located in Slough, Berkshire which produces 80MWth and supplies 28 MWe to the National Grid and heat to local sources and has an annual fuel requirement of up to 150,000 tonnes per annum of feedstock[1]. A new facility is planned on the site - Slough Multifuel EFW 'multifuel' site similar to facilities at Ferrybridge 1 and 2 that will use a variety of Municipal Solid Waste as its fuel sources[2].

In 2008 Scottish and Southern Energy (SSE) acquired Slough Heat and Power (SH&P) from SERGO for £49.25m[3].

The plant was converted to renewable fuel in c.2001 at a cost of approximately £30m[4] and this led to the development of an innovative, integrated supply chain for secure fuel supply in partnership with local suppliers such as Thames Valley Energy, a not-for-profit renewable energy agency[4].

The plant supplies all of the business located on the same trading estate with heat, electricity and hot water. Over 2000 nearby homes are also supplied with their electricity from the plant via 100 km of underground cable as part of a private electricity network[4].

Plant

The six boilers and turbines at the SH&P energy center can operate on a wide variety of fuels, ranging from renewable sources such as wood and fibre through to natural gas, coal and distillate. A small amount of natural gas and coal is used to control the boilers. As part of the plant, steam from two wood-fired fluidised bed boilers is directed to a 35 MW pass out steam turbine. A new multi-fuelled vibrating grate boiler dedicated to burning fibre fuel pellets and wood chip, was commissioned based on a contract under the 4th Non-Fossil Fuel Obligation scheme[4].

The total electrical output of the combined system is 50 MWe of which 40 MWe comes from wood chips and 10 MWe from Waste Derived Fuel (fibre fuel) in addition to 20 MWth[4].

Tonnage Input/Fuel

The tonnage received by the plant in the most recent Annual Sustainability Report for 2018-19[5] was reported by Ofgem as follows:

Biomass Tonnage (2018-19)
Wood Waste 98,812
Other 0
Total 98,812

Whilst all of the tonnage reported was Wood Waste in the Annual Sustainability Report and the EA waste returns, the site notes that it sources pellets from Fibre Fuel Limited, a subsidiary company of SH&P, comprising non-recyclable waxed cardboard, laminates, photographic paper and mixed papers. The pellets also have non-PVC plastics added, up to a volume of 15%, to improve the Calorific Value of the fuel[4].The Wood Waste tonnage received cannot be directly compared with the stated historical tonnage received and recorded in the EA statistics as these are recorded on a calendar year basis (i.e. January 2018 to December 2018) and was 99,485 tonnes.
