MANCHESTER, N.H., Sept. 16, 2026 (GLOBE NEWSWIRE) — Eversource today announced ISO New England\u2019s (ISO-NE) selection of the company\u2019s joint Transmission Initiative Down East (TIDE) project as the preferred longer-term transmission solution to meet regional needs outlined by ISO-NE in its competitive transmission solicitation process. The proposed TIDE project will enhance reliability for customers and enable new energy supply sources in northern New England \u2013 easing congestion on the regional transmission system and helping to address affordability.<\/p>\n

Through ISO-NE\u2019s competitive bid process, TIDE emerged as the strongest overall and most cost-effective solution to meet the region\u2019s energy needs with significant customer benefits \u2013 including expanded system capacity, reduced congestion costs, enhanced reliability and the ability to integrate to the regional grid up to 1,200 megawatts of future onshore wind generation in northern New England. The proposed project still requires extensive engineering, environmental, permitting and regulatory reviews, with construction anticipated to begin in 2029 pending all state and regulatory approvals.<\/p>\n

\u201cThis selection is an important step toward delivering the modern, reliable transmission infrastructure New England needs while enabling new supply resources that are so critical to addressing our region\u2019s longstanding energy affordability challenges,\u201d said Bill Quinlan, President of Transmission at Eversource. \u201cTransmission solutions like this project can help improve affordability for customers across New Hampshire and all of New England by enabling greater supply capacity and easing congestion costs while also ensuring customers have the highly reliable service they demand. We look forward to further engagement with our communities, ISO New England and other stakeholders to bring these benefits to the region.\u201d<\/p>\n

According to ISO New England\u2019s analysis, TIDE is projected to provide substantial regional benefits at a more than 2-to-1 cost-benefit ratio, including:<\/p>\n
