The Walney offshore wind farm, located in the Irish Sea, could triple in size after extension plans for the site were given the government’s seal of approval.
The wind farm, which will eventually generate enough energy to power more than half a million homes, is expected to create 230 jobs during construction and an additional 185 jobs annually during its planned 25-year lifespan.
Energy and Climate Change Secretary Ed Davey said the government’s go-ahead reinforced a strategic effort to position the UK as an attractive place to invest in offshore wind.
He added: “Another large wind farm is now closer to being built – and each one gives us more home-grown, clean and secure energy supplies.
“This government has worked tirelessly to rebalance the economy and create more green jobs. This project alone is expected to create 230 new jobs during the construction phase and many more opportunities throughout the UK economy.
“Driving investment in energy has made us the top country in the world for investing in offshore wind.”
