According to a recent LinkedIn post from Grid Status, the 1,200 MW New England Clean Energy Connect transmission line between ISO New England Inc. and Hydro Québec has been operating for just over a month. The post notes that since commercial start on January 16, the line has averaged more than 900 MW of exports, delivering roughly 734,000 MWh and displacing higher-cost winter fossil generation.

The company’s LinkedIn post highlights that this early performance implies a capacity factor of about 79.8%, but it also points to operational constraints under extreme cold conditions. During late January’s Arctic temperatures, the post observes that Quebec’s heavy reliance on electric heating led Hydro Québec to curtail exports on NECEC and even import power via other interties during an ISO-NE M/LCC2 event.
The post suggests that Hydro Québec faces an ongoing tension between growing export ambitions and rising internal winter peak demand, especially under drought conditions that can limit hydro resources. For investors, these dynamics may indicate that while NECEC adds substantial clean import capacity to New England, actual utilization could be materially weather dependent, affecting realized economics versus nameplate expectations.
As referenced in the LinkedIn commentary, prior research from Grid Status has examined the structural challenges around Hydro Québec’s winter reliability and export strategy. This context may be relevant for assessing long-term transmission congestion risks, pricing volatility in ISO-NE, and the robustness of policy and investment theses tied to large-scale Canadian hydro imports into the U.S. Northeast.
