The new Siemens wind turbine factory in Hull has officially opened today.
The first wind turbine blade to be manufactured at the £310 million plant at Alexandra Dock was unveiled by the Secretary of State for Industry Greg Clark.
The redevelopment has brought around 1000 jobs to the UK, 700 of which have gone to people from the surrounding area.
The site, which is the size of 78 football pitches, includes a factory which will manufacture blades 75 meters long and a dockside plant assembling turbine towers 82 meters tall.
Dr Doug Parr, Greenpeace Chief Scientist welcomed the new jobs and investment to the area, he said:
Fiona Dywer spent the day at the plant to witness the historic moment the e very first giant wind turbine blade came off the production line - signalling the start of a brand new era for green industry in the region.
