Budding Irish offshore developer Oriel Windfarm Limited has joined forces with two established competitors -- Airtricity and Codling Wind Park -- to propose a north-south interconnector off the east coast of Ireland. The company behind the Codling project is a joint venture between Fred Olsen Renewables and Eco Wind Power, a subsidiary of property group Treasury Holdings. The transmission line would link the offshore wind stations proposed by the three companies to the government's planned subsea interconnector between Ireland and Britain. The interconnector route would extend from Wexford in the south of the island to Armagh in Northern Ireland, on the way linking up Airtricity's Arklow Banks project off Wicklow, the proposed Codling Wind Park between Greystones and Wicklow, and Oriel's planned Clogher Head wind farm. Brian Britton from Oriel says the subsea proposal is an alternative to an overland cable route in an area that is already congested. The companies are ready to officially propose a public-private partnership with the government. The Irish government, meantime, is poised to approve the EUR 500 million finance plan for the 300 kilometre east-west interconnector between Ireland and Britain.
