In a consortium with Milan-based cable company Prysmian, Siemens Energy is planning to build a submarine DC interconnector in the Irish Sea.

Siemens says the customers are British grid operator National Grid Electricity Transmission (NGET) and its Scottish counterpart Scottish Power Transmission (SPT), which founded the special-purpose joint venture NGET/SPT Upgrades Ltd. for this grid expansion project.

The grid connection between Scotland and England is designed as a low-loss, high-voltage direct-current (HVDC) transmission system.

According to Siemens, this will be the first submarine interconnector to use a DC voltage level of 600 kV. The highest voltage level used to date was 500 kV.

The Western HVDC Link project will provide much-needed additional power transmission capacity on Britain's transmission system as the U.K. heads toward a low-carbon economy. The power link will help to balance supply and demand within the grid sections in light of the continued growth of remote and fluctuating renewables, such as offshore wind. The link is scheduled to be operational by late 2015.
