Elean is the largest straw-fuelled power station in the world, and one of the most reliable. It has one of the highest load factors for a renewable energy facility.
The plant has a capacity of 38MW and generates more than 270GWh of electricity annually. It uses 200,000 tonnes of biomass each year.
The usual fuel is cereal straw, although the power station also burns oil seed rape and miscanthus (elephant grass, a tall high-yield crop related to sugar cane). It can also use up to 10 percent natural gas.
Biomass is incinerated on a vibrating grate. This heats water in the boiler, producing steam at 540 degrees Celsius and 9,200kN per square metre pressure.
The steam drives a turbine connected to an electrical generator. The electricity goes to the National Grid, while the steam is condensed into hot water and returned to the boiler. Exhaust gases from the combustion chamber are treated (cleaned and purified) before release.
The station was constructed by FLS Miljo and completed in December 2000. EPR Ely Ltd assumed responsibility for operation and maintenance in June 2004, with the intention of using a wider range of fuels — supplied by subsidiary Anglian Straw Ltd.
