Technology

The Markinch Biomass CHP Plant converts energy from the fuel to heat and then electrical power. Fuel is burned in a high efficiency boiler, producing steam which is passed to a steam turbine to generate electricity.

Markinch Biomass CHP Plant is reducing fossil fuel derived carbon dioxide emissions by around 250,000 tonnes per annum and is making a major contribution to the Scottish Government’s renewable energy generation targets.

During operation a white plume of steam from the stack may be visible. The plume consists of water vapour and is a result of the high moisture content of the fuel being burned. This is a natural bi-product of the biomass process. It has no impact on the air quality.

The plant is fuelled by both recovered and virgin wood, with virgin logs being chipped at the Off-site Fuel Processing Facility at the former Bowhill Colliery site in Cardenden. Operated by The Purvis Group, the site chips, stores and supplies fuel to Markinch. Each month, the facility chips up to 6,500 tonnes of virgin wood supplied from a number of Forestry Commission Scotland certified sources. The site can also store 25,000 tonnes of recovered wood each year. The recovered wood is diverted from landfill.
