Project Profile

  • Labrador - Island Link

    The Project

    Labrador - Island Link (LIL) is a 1,100 km 900-MW high voltage direct current (HVDC) transmission line that carries electricity from a generating facility at Muskrat Falls to the island of Newfoundland. The line runs from central Labrador, crossing the Strait of Belle Isle, and extending to Soldiers Pond on the Avalon Peninsula. It is owned and operated by Nalcor Energy. ATCO has been providing services to Nalcor Energy since 2017, including overall technical leadership for converter stations, engineering expertise to oversee system studies, integration studies, control and protection testing, commissioning and construction oversight, operations and maintenance support and staff training.

    Executed across a geographically immense area, the project involved eight sites of varying sizes and project influence, spanning more than 1,600 km, and logistical challenges with four sites in a remote, sparsely populated area in Labrador. The sites were divided into multiple contracts, requiring careful review and planning to ensure integration of O&M.  

    The project also involved integrating new technology into an existing grid and energy control centre. Despite these challenges, an operational site was delivered in the prescribed timeline while meeting Nalcor Energy’s safety targets.
