Welsh Secretary Cheryl Gillian told the BBC that RWE Innogy's project, Gwynt y Mor - which translates as "wind in the sea" - is expected to make up to 1,000 new jobs available.
However, similar ventures may be difficult to launch as planning permission can be difficult to obtain for a "decent-sized wind farm".
Adam Bell, national campaigns coordinator at RenewableUK, commented that just 25 per cent of applications to construct turbines get approved and even then it can take a long time before building is allowed to start.
"This is possibly the biggest obstacle facing the industry in terms of its rapid development in the UK," he stated.
