A power station in Shropshire is to permanently close after 46 years of generating electricity.
Ironbridge Power Station, originally coal-fired, was converted to burn wood pellets to reduce emissions ahead of its planned closure this year.
The historic plant was capable of generating up to 1,000MW from two units at full capacity but the output was reduced to 750MW following the conversion.
It has reached its 20,000 hours limit of generation under an EU legislation.
E.ON CEO Tony Cocker said: “I’m hugely proud of the contribution Ironbridge Power Station has made to the UK’s energy infrastructure for almost half a century.
“The closure of such an iconic plant will of course be tinged with sadness having played such an important role in the community – over 400 people worked on site when Ironbridge was at the peak of generation, many from the local area.”
A small team will now begin the decommissioning phase, which is due to run until early 2017.
