Guernsey commerce and employment minister Kevin Stewart said it was looking at costs and would need to work with either France or the UK.
The Channel Islands are a British Crown Dependency, albeit geographically closer to France.
Stewart said: "We will have to partner with either France or the UK because we can't take that much power."
The turbines are likely to be in the 3MW range. One potential issue is Guernsey's territorial waters only extend three nautical miles, although talks are ongoing to take this to 12. If the territorial waters are extended the wind farm would go over 100MW.
In 2011, the Channel Islands signed a deal with the UK government to develop offshore wind. Britain is developing an All Islands Approach to link with Ireland and France via the Channel Islands, as well as a Nordic-Baltic Initiative.
Isle of Man targets offshore
Similarly, the Isle of Man, situated off the British coast in the Irish Sea, is also aiming to become an offshore wind hub for the Irish Sea and develop around 225MW in its waters.
Like the Channel Islands, the Isle of Man is a self-governing British Crown Dependency, and owns its own seabed up to 12 miles from the shoreline.
Initial government estimates suggest an immediate offshore wind potential of 225MW, with a favoured option of between 22 and 55 5MW offshore turbines.
