Cape Wind on Thursday said it has signed contracts with two companies for the cables needed to transport power generated by the 130-turbine offshore wind farm.

Prysmian Cables and Systems USA of South Carolina will make the onshore transmission cables that will connect Cape Wind to an NStar substation in Barnstable, Cape Wind said in a statement. Underwater cables, meanwhile, will be installed by Caldwell Marine International, which is based in New Jersey.

Cape Wind president Jim Gordon called both firms “capable companies that will help establish a domestic offshore wind supply chain.”

Cape Wind did not disclose the amount of the contracts.

The deals are the latest of several announcements that the long-awaited Cape Wind has made about supplier contracts or financing in the last several months. The $2.5 billion project has been in the works for more than a decade.

So far, the company has secured $900 million in financing, including a $600 million loan from EKF, the Danish Export Credit Agency, that was announced in late February.

In December, Cape Wind also finalized a deal to purchase giant turbines for the project from a Siemen’s subsidiary.
