Drax is undergoing a major transformation programme to convert its 4GW power station – which supplies around 8% of the UK's power – from coal to sustainable biomass. Two out of six units have now been converted and plans are advanced to convert a third unit to high-biomass later this year. The estimated 12 million tonnes of carbon saved once three units are fully converted is equivalent to taking 10% of the UK's total vehicle fleet off the roads and makes Drax the single largest decarbonisation project currently underway in Europe.
