The UK Department of Energy and Climate Change (DECC) has granted consent to Anglesey Aluminium Metal Renewables to build a 299MW biomass fuelled power station in Anglesey, UK.
The plant, which will be constructed at Penrhos Works in Holyhead, will generate enough electricity to power about 300,000 homes.
The operator of the facility is expected to source fuel from both imported and local sources, with imports coming in through the Port of Holyhead.
UK minister of state for energy Charles Hendry said biomass power stations such as this one in Anglesey will provide a reliable, secure, flexible and renewable source of power.
"We want a balanced energy portfolio and we want biomass to play a key role in this," Hendry said.
