A new £300m multifuel energy plant at Ferrybridge Power Station is now generating enough electricity to power around 160,000 homes.
Work on the first phase of Ferrybridge Multifuel 1, a project between SSE and Wheelabrator Technologies, is now complete.
Contractor Hitachi Zosen Inova started building the plant in 2012 and has now handed the facility back to SSE and Wheelabrator.
The plant takes waste derived fuels to produce around 70MW of electricity for the National Grid.
Tom Maillet, director of engineering and operations for Multifuel Energy Ltd, said: “The commencement of commercial operations at the Ferrybridge Multifuel 1 project is a great achievement for everyone who has been involved and I would like to thank each and every team member for their hard work and dedication.
“I would also like to thank HZI for delivering such a high quality plant.
“We are excited to reach this milestone, and are now looking forward to concentrating on operating safely, successfully and efficiently.”
Franz-Josef Mengede, chief executive of Hitachi Zosen Inova, said: “Today marks the end of the construction phase to build the Ferrybridge Multifuel 1 project. We are proud to deliver a plant that sets a new milestone in fuel flexibility, size and energy efficiency to our customer safely and within the expected timeframe.”
SSE announced it will close Ferrybridge Power Station with the loss of up to 400 jobs in May.
