The 62 huge wind turbines that are drilled into the seabed 10 miles off Cap Frehel are visible from both Guernsey and Jersey today (19 January).

The clean air that's blown in from the Arctic has made visibility exceptional over the past two days.

It means that the St Brieuc turbines are visible on the horizon from Guernsey's south coast. Jerbourg is a good place to spot them, slightly to the side of the Roches Douvres lighthouse and rocks.

In Jersey, they can spotted from places like La Corbiere or the cliffs near the prison.

The windfarm development is already producing energy, when the wind blows, but it's not yet complete.

When it is, it will produce enough power for more than 800,000 people, or roughly 9% of Brittany's energy needs.

The turbines themselves are huge, and measure just over 200 metres from their base to the tip of the blade, seen vertically.

The windfarm is being gradually commissioned and as work continues, three vessels, either supply or crew transfer ships, have been registered under the Jersey flag and are using St Helier as a base. One of these is the Farra Grainne, taken by Mark Pulley, and seen below.
