UK power plant Drax has stated that it will significantly boost its renewable power generation to become a mainly biomass-fuelled plant, if the government makes it commercially viable through subsidies.

The Drax group, which supplies around 7 per cent of the UK’s electricity, wants to burn more biomass to extend the plant’s lifespan.

Drax generated 8 per cent of its electricity from biomass during the first six months of 2011, although this was below its 12.5 per cent capacity as it waits for clarity on subsidies.

Drax said this equated to around 6 per cent of the UK’s renewable power output, making the plant the UK’s single biggest source of renewable energy.

Drax, which is also the UK’s biggest single source of carbon emissions, has reported a rise in first-half underlying earnings, but warned full-year profits would fall as coal prices continue to climb.

Earnings before interest, tax, depreciation and amortisation increased 3 per cent to £190m ($310m) in the first six months of 2011.
