In 2003, Sea Breeze undertook a comprehensive investigation of independent transmission options to increase British Columbia's connectivity within the regional grid.

The review of transmission options culminated in a Joint Venture Agreement being executed with Boundless Energy LLC, of York Harbor, Maine, for development of several independent transmission projects. 

A significant milestone occurred on September 7, 2006, when the Juan de Fuca Cable Project, a 550 megawatt High Voltage Direct Current (“HVDC”) Light® submarine transmission line planned to connect British Columbia, and Washington State, became the first international merchant transmission line to be approved by the National Energy Board of Canada.
