With the introduction of 1,200 MW of new hydropower into ISO-New England’s system, the NECEC will diversify its power supply, strengthen grid stability, and mitigate risks to the grid during extreme weather events. At the same time, NECEC’s low-cost energy supply and predictable pricing structure will help reduce fuel-related volatility, create a strategic hedge that enhances regional competitiveness, and reduce wholesale electricity prices, delivering long-term cost savings for New England ratepayers.
The NECEC transmission line consists of a new 145-mile-high voltage direct current (HVDC) transmission line from the Quebec-Maine border to the new Merrill Road converter substation located in Lewiston and new 1.2-mile 345 kV alternating current (AC) transmission line from the new Merrill Road converter substation to the existing Larrabee Road substation. The year-one property tax benefit to host communities is approximately $23 million.
Avangrid’s arrival to this point reflects an unwavering commitment to transparency, environmental stewardship, and community engagement. Over the past several years, the NECEC project has:
NECEC’s financial foundation is strong, anchored by long-term, fixed-rate contracts with credit worthy utility counterparties that ensure predictable cash flows and a fair return on investment for the life of the project. The project is secured by a combination of a 40-year Transmission Service Agreement with Hydro-Québec and 20-year contracts with Massachusetts utilities and Hydro- Québec, providing stable, inflation-protected revenue streams and minimizing market volatility. Capital expenditures totaled approximately $1.6 billion. As a result of negotiated contract provisions, the project will recover cost increases due to electoral challenges, ensuring the end project achieves the anticipated economic value.
With major execution risks including permitting, legal challenges, and construction fully resolved, the NECEC has transitioned from development to revenue generation. Coupled with its measurable environmental benefits and alignment with relevant ESG mandates, the project is also positioned for premium valuation among sustainability-focused investors, making it one of the most resilient and attractive infrastructure assets in the region.
