The US Energy Information Administration reported that the New England Clean Energy Connect (NECEC) — a 1,200 MW high‑voltage transmission line connecting Hydro‑Quebec to ISO‑New England — began commercial operation on January 16, 2026. Designed to increase hydroelectric power imports from Canada to New England, the line initially boosted net imports. However, during Winter Storm Fern, cold weather led Quebec to limit exports, stopping NECEC flows from January 24–26 and prompting New England to increase petroleum‑based generation. For a period, New England exported more electricity to Canada than it imported before trade balanced again by January 27. The EIA writes:
Over the past few years, Independent System Operator-New England (ISO-NE) has relied less on Canada for electricity. On January 16, 2026, the New England Clean Energy Connect (NECEC), a 1,200 megawatt (MW) transmission line project, began commercial operation. The new high-voltage direct current NECEC transmission line is primarily intended to increase the amount of hydroelectric power exported from Canada to New England. However, during Winter Storm Fern, New England exported more electricity to Canada than it imported.
After the transmission line began commercial operation, net electricity imports to ISO-NE initially increased for several days. Starting the weekend of January 24, however, an Arctic cold front covered large portions of the United States and Canada, resulting in extreme cold conditions in New England and Eastern Canada.
On January 24, power flows on NECEC stopped and largely remained offline until January 26 as Quebec limited electricity exports to meet domestic demand. Starting on January 24, electricity generation from petroleum in New England, which is used during winter periods when cold weather creates high demand for electricity, increased and surpassed generation from natural gas.
With imports from NECEC halted and generation in New England increased, ISO-NE exported more electricity to Canada than it received starting at 3:00 p.m. on January 24 through 11:00 p.m. on January 25. Between January 26 and January 27, net electricity outflows from ISO-NE to Canada decreased and trade became more balanced.
