Vattenfall shrinks onshore infrastructure for Norfolk offshore wind farms

Vattenfall has announced plans to reduce the size and footprint of the onshore electrical infrastructure near Necton required for the Norfolk Offshore Wind Zone by around a quarter. It follows feedback from local stakeholders which requested the electrical infrastructure be made as discreet as possible in the local landscape.

By using newer cables and an innovative configuration of the electricity network, Vattenfall revealed it has been able to reduce the number converter stations to be built from four to three – reducing the footprint of the electrical infrastructure.

Alongside the smaller area required, a proposed new layout for the electrical infrastructure will also help it appear more compact and reduce the extent it is visible to the south and north.

Rob Anderson, Project Director of Vattenfall’s Norfolk Zone, said: “We’re committed to the region so it’s great to be able to use new, innovative solutions to deliver improvements for local communities. We’re using cutting-edge engineering that will help us to reduce the overall impact on residents which includes minimising the visual impact.

“The Norfolk Boreas Offshore Wind Farm will also be a great boost for the local economy, supporting jobs and growth, as part of the Norfolk Offshore Wind Farm Zone. We’ll continue to work closely with communities to make sure that lasting local benefits deliver for people in the region, as well as bringing clean, secure, home-grown power to millions of homes across the country.”

Earlier this month, Vattenfall has been awarded a CfD for the Norfolk Boreas offshore wind farm, the first phase of Vattenfall’s Norfolk Offshore Wind Zone. The UK Government has awarded Vattenfall a CfD at £37.35/MWh (2012 prices) for the 1.4GW Norfolk Boreas Offshore Wind Farm.

Subject to a final investment decision, construction will begin next year. Norfolk Boreas is the first phase of Vattenfall’s Norfolk Offshore Wind Zone and comes ahead of the Norfolk Vanguard offshore wind farm. Once complete, the Norfolk Zone is expected power more than four million homes and will be one of the largest offshore wind zones in the world.
