Why Alderney?

Alderney is surrounded by some of the potentially most productive tides in Europe. Recent data is shown on the map below. Alderney owns the seabed out to three nautical miles from its baselines, covering over ninety square nautical miles of accessible tidal flow and is in the process of claiming economic rights out to twelve nautical miles, covering nearly 500 square nautical miles of accessible tidal flows. The Commission offers simple but robust licencing and consenting arrangements to developers.

 
Tidal Resource

Alderney has the second largest tidal resource in North West Europe as demonstrated in the map shown below. Independent estimates of the energy that could be harvested using current technology from tidal flows within the 3nm limit range from 1GW to 3GW.

 
Proximity

In close proximity to both the south of England and France with associated demand for green power. There are purpose built deep water port facilities to support marine renewable energy systems in Cherbourg France situated within 20nm http://uk.pna-emr.fr/

 
Interconnector

An interconnector from France via Alderney to Britain (Fab Link Ltd) is planned for connection in 2020. This direct current link (1400 MW capacity) aims to strengthen the interconnection capacity between France and Britain and provide an export link for marine renewable energy projects in Alderney`s waters.
