NERC's New Winter Reliability Assessment Raises Concerns for Elevated Risk of Insufficient Supplies to Meet Demand in Extreme Operating Conditions

LCG, November 19, 2025--NERC yesterday released its 2025–2026 Winter Reliability Assessment (WRA), which concludes "much of North America is again at an elevated risk of having insufficient energy supplies to meet demand in extreme operating conditions." The WRA does state that resources are adequate for normal winter peak demand, but extended, wide-area cold snaps will be challenging.

FERC Approves Maritimes & Northeast Pipeline Expansion

LCG, March 14, 2007--The Federal Energy Regulatory Commission (FERC) authorized Monday Maritimes & Northeast Pipeline, L.L.C. (Maritimes) to add facilities that would nearly double the capacity of its natural gas system to receive gas from the Canaport liquefied natural gas (LNG) receiving terminal in Saint John, New Brunswick. Maritimes expects that the expansion will create a more efficient and reliable pipeline system, as well as increase gas supply availability. Maritimes plans for project construction to commence this year, and the in-service date target is November 1, 2008.

Maritimes' Phase IV Project includes a number of modifications to its existing pipeline system that are designed to increase the system capacity from about 418 MMcf/day to over 833 MMcf/day. The facility costs are estimated to be $321 million. The project includes building five new compressor stations in Maine, installing nearly 2 miles of 30-inch diameter pipeline in Baileyville, Maine, plus improvements to existing facilities in Maine and Massachusetts.

In addition, the FERC approved Maritimes' request to allow increased imported volumes of natural gas from Canada and to construct and operate an additional interconnection at the U.S.-Canada border near Baileyville, Maine.

The plans call for the re-gasified LNG to be transported from the LNG terminal via the proposed Brunswick Pipeline to an interconnection with the Maritimes system at the U.S.-Canada border. The Brunswick Pipeline, which is to be owned and operated by Emera Brunswick Pipeline Company Ltd, a subsidiary of Emera, Inc., is seeking Canadian regulatory approvals, according to Maritimes.

The Canaport LNG is a limited partnership of subsidiaries of Repsol YPF and Irving Oil Limited. Maritimes is owned by affiliates of Spectra Energy (77.53 percent), Emera Inc. (12.92 percent) and Exxon Mobil Corporation (9.55 percent).
