Woodstock-Houlton International Power Line Project

The Houlton Water Company has entered into an agreement with NB Power for the construction of a new power line in New Brunswick to supply electricity to Houlton, Maine.

If approved, customers in Houlton would be served from the NB Power grid through a new power line that would be connected to an existing line near Woodstock. The total length of the new power line would be approximately 18km, 16km of which would be on the Canadian side of the international border and 2km of the line would be on the US side. The construction of a new substation in New Brunswick near the Maine-NB border would also be necessary.

Transmission line projects of this scale are subject to regulatory review and approval. This project requires approvals from both provincial and federal regulators.

On July 25, 2017, NB Power registered the project with the New Brunswick Department of the Environment and Local Government in accordance with Section 59.1) and Schedule “A” of the Environmental Impact Assessment Regulation – Clean Environment Act. On February 16, 2018, the project was approved under this legislation with a Certificate of Determination signed by the New Brunswick Minister of Environment and Local Government. In spring 2018, NB Power will file a permit application for this project under The National Energy Board Act.
