Science & Discovery: Discover the Globe With Research Study and Technology
- NECEC has not significantly increased net hydropower to New England, often redirecting flows previously carried by the Phase 2 line.
- Multiple outages left NECEC idle on many days; Hydro-Québec attributes interruptions to technical issues and optimization needs.
- Quebec drought and reservoir limits forced Hydro-Québec to prioritize domestic supply, reducing exports and sometimes importing over Phase 2.
- Contracts protect Massachusetts ratepayers with penalties for shortfalls; NECEC has occasionally displaced gas plants, showing potential long-term decarbonization value.
When the New England Clean Power Link transmission line began bring electrical power from Canada right into Maine in January, supporters hailed the project as a triumph for sustainable power. Currently, after virtually six months of procedures, the early numbers question regarding whether the project will certainly be able to progress the region’s power transition as high as promoted.
Power flow right into New England is up just marginally, and there have been approximately 27 days when no power in all traveled along the new line, typically called NECEC. If existing trends hold, New England will receive less hydropower this year over 2 transmission lines than it corrected simply one line in 2023 and previous years.
“What we have actually seen so far is not what some people expected to see,” claimed Joseph LaRusso, supervisor of the Tidy Grid Program at environment not-for-profit Acadia Facility.
Possibly placing additional strain on the supply of Canadian hydropower is the Champlain Hudson Power Express, a transmission line that started sending electricity from Quebec into New York City City this month
NECEC has its beginnings in a 2016 Massachusetts regulation that called for the state to acquire 1 6 gigawatts of offshore wind power and one more 1 2 gigawatts of added renewable resource. The plan was to contract with state-owned Canadian power supplier Hydro-Québec to use the area’s abundant hydropower sources and construct a brand-new transmission line to bring the electrical power south.
The first proposal– a 192 -mile job with New Hampshire– was abandoned in 2019 after public protest concerning the impact on the state’s forests. The transmission line via Maine encountered comparable conflict. In 2021, a statewide referendum ballot placed the project on hold till 2023, when a court ruled that the development might be rebooted.
Two and a half years later, NECEC came online and started bring the very first electrons into New England. It’s definitely a significant achievement in a time when the Trump administration has been doing all it can to quit progress on tidy energy, including overseas wind– the keystone of the Northeast’s decarbonization plans. And although the results up until now have actually been combined, some see prospective for the line to make a large impact on New England’s clean power future.
How much hydropower is coming from Quebec?
When NECEC came on-line previously this year, Massachusetts Gov. Maura Healey, a Democrat, and climate advocates promoted it as a significant win for the state’s renewable energy goals and a way to conserve homeowners cash on their energy bills. Massachusetts contracted with Hydro-Québec for 9 55 terawatt-hours of hydropower each year, approximately 20 percent of the state’s annual electricity demand.
The procedures have actually not had the smoothest start. NECEC was totally non-active for numerous spans– from a half day on April 28 to virtually two weeks at the end of May and beginning of June. One of the most recent failure was because of ” technological troubles,” Hydro-Québec speaker Lynn St-Laurent stated in a written statement.
“As soon as repair work were finished, distribution resumed,” she stated. ” With any brand-new transmission infrastructure, a duration of optimization and fine-tuning is to be anticipated.”
Still, most of the time, hydropower has moved progressively on the brand-new facilities. Through the end of April, Hydro-Québec exported concerning 2 4 terawatt-hours of power on the transmission line.
If the power is (primarily) moving as planned, why are some people still hesitant that the project will supply the assured benefits? Due to the fact that up until now, it hasn’t done much to include in the overall supply of renewable resource in New England.
Prior to NECEC, New England already imported significant amounts of hydropower on a transmission line called Phase 2, which runs from Quebec right into main Massachusetts. In 2019, the year the Massachusetts regulators accepted the contracts in between utilities and Hydro-Québec, greater than 12 terawatt-hours traveled onto the New England grid over the line.
However beginning in 2023, Hydro-Québec started marketing much less and less energy to New England over Stage 2 For almost three weeks in very early 2025, exports ceased completely Through completion of April this year, just over half a terawatt-hour has come south over that line. On paper, it can look a lot like NECEC isn’t permitting more energy right into New England but is rather just offering it a new road to follow.
“We’re not seeing much net new flows originating from our next-door neighbors,” claimed Dan Dolan, president of the New England Power Generators Association. ” We are running pretty near to the internet power moves we had in 2025, which were the most affordable quantity of imports that New England has ever before received from Quebec.”
At the same time, Quebec has begun importing power over the Stage 2 line, a rare event prior to 2025 In the very first 4 months of this year, greater than 500 gigawatt-hours taken a trip right into Canada on the line. Due to the fact that New England’s electrical power supply depends heavily on natural gas generation, the area is still shedding nonrenewable fuel sources to deliver energy north although it is receiving hydropower for its own use.
“We’re seeing a much heavier gas shed on the rest of the generation fleet than I believe a number of those states had presumed going into this year,” Dolan said.
Power imports and exports
The primary vehicle driver behind slowing exports appears to be the drought problems that have actually lingered in Quebec for the previous few years. During wetter durations, the hydropower industry utilizes large storage tanks to store water to aid it come through these drier times, claimed Gilbert Bennett, a senior consultant for WaterPower Canada, a hydropower profession team.
As generators await rainier days, their very first commitment is to supply residential consumers, he claimed. That means there will likely be times when Hydro-Québec requires to import electrical energy over the Phase 2 line to balance out several of the hydropower it is contractually required to send to Massachusetts over NECEC.
“Power streams between Québec and New England are vibrant and vary continually based on market conditions and system requires on both sides of the boundary,” St-Laurent stated.
Economically, New England clients must not go to danger from these recurring changes, LaRusso said. Massachusetts’ agreement with Hydro-Québec consists of stipulations that call for the Canadian company to pay punitive damages if it falls short to supply according to its agreement.
“To the degree that imports are cut, Hydro-Québec is liable to make the electrical utilities whole for the cost of replacement power,” LaRusso said.
It is less clear whether NECEC will improve Massachusetts’ renewable resource supply in the long run.
Still, the new transmission line has at times demonstrated its possible to assist New England achieve a cleaner energy supply, LaRusso said. He indicated May 16, a warm day when solar power reduced demand on the grid and NECEC was going full tilt. Gas plants were running at low levels, and a lot of the power was heading to New york city. For a brief time, all the area’s power needs could be met by nonfossil gas resources.
“Hypothetically, [grid operator] ISO New England can’ve turned off its gas generators,” LaRusso stated. ” It really gets you thinking about the sources available and how they could be managed and cooperated the future.”
Bennett is likewise positive in the long-term overview. As a whole, he stated, climate modification is anticipated to create wetter problems in Quebec. And the region is investing greatly in additional hydropower facilities as well as onshore wind. The years ahead, he claimed, will certainly bring a lot of renewable energies to show to Canada’s southerly neighbors.
“Over the long term, we see a brilliant future,” Bennett stated.
