Summary
A Biomass EfW facility Slough Heat & Power is a 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].
Annual Sustainability Tonnage Input/Fuel
The tonnage[5] 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[6]:
| Year | Waste Wood (m3) | Waste Wood (t) | Straw | Miscanthus | Arboricultrual Waste | Sawmill Residue | Foresrty Residue | Round Wood | Short Rotation Coppice | MBM | Other Material |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 2020/21 | 0 | 92117 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
| 2019/20 | 0 | 95287 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
| 2018/19 | 0 | 98812 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
| 2017/18 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
Waste Tonnage, By Origin
The table shows a list of the Waste for the Permit CP3031SX, that has arrived into sites as reported to the Regulator and then publicised in their reported statistics. The Data was last updated on October 2024. The total reported tonnage arriving at the site was: 124,911.41t.
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.
| EWC Code | Origin of Waste | Tonnes In |
|---|---|---|
| 19 12 07 | Lewisham | 2608.23 |
| 19 12 07 | Wiltshire | 15897.24 |
| 19 12 07 | London | 40592.04 |
| 15 01 03 | Lewisham | 1155.82 |
| 19 12 07 | Bracknell Forest | 10025.50 |
| 19 12 07 | Suffolk | 2807.08 |
| 19 12 07 | Fareham | 266.44 |
| 15 01 03 | Hounslow | 11166.84 |
| 15 01 03 | London | 7428.07 |
| 17 02 01 | Slough | 9180.58 |
| 19 12 07 | Hounslow | 3017.73 |
| 19 12 07 | Hampshire | 20765.84 |
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].
