Mainstream Works With Portugal, China to Study Irish Wind Link

Mainstream Renewable Power Ltd., a Dublin-based renewable-energy developer, will team up with utilities from Portugal and China to study building a 5,000- megawatt link to export wind power from Ireland to the U.K.

The Irish company struck a preliminary deal with Portugal’s REN-Redes Energeticas Nacionais SA, part-held by China State Grid Corp., that may result in a joint venture to finance and build the Energy Bridge link, Mainstream said today. Britain’s National Grid Plc (NG/) would also be involved in any partnership.

The Energy Bridge venture has already secured an offer for 5,000 megawatts of grid connection to the U.K., Mainstream said in a statement. The transmission line, which would transport power from Irish wind parks under the sea, is slated to deliver electricity in an initial 1,200-megawatt phase by 2017.

The companies will complete feasibility studies and a business plan for the development and financing of the project. China State Grid is the largest shareholder in Portugal’s REN, according to data compiled by Bloomberg.
