The wind farms will be able to provide energy to about 445,000 homes
Work to construct two wind farms off the south Cumbrian coast will begin in the summer, it has been announced.
More than 100 turbines will make up the Walney Offshore Wind Farm, situated 9.3 miles (15km) west of Barrow-in-Furness.
The Ormonde Offshore Wind Farm will have 30 turbines, located about 6.2 miles (10km) off at Walney Island.
Once both projects are complete, at the end of 2011, they will together produce enough renewable energy for about 445,000 households.
Danish company Dong Energy and SSE (Scottish and Southern Energy) are behind the Walney project, which will be built in two stages, each consisting of 51 turbines.
The Ormonde Offshore Wind farm will be built and operated by Vattenfall, a Swedish energy company.
An exhibition is being held at the Forum in Barrow on Wednesday afternoon where members of the public can question a team of experts and senior members from each project.
