The Coalition for a New England – Maritimes Offshore Energy Corridor

The proposed New England – Maritimes Offshore Energy Corridor (NEMOEC) is a shared offshore backbone transmission corridor that directly connects US and Canadian offshore wind (OSW) resources to population centers and industrial users at the coasts. Our vision for transformative interregional electricity infrastructure will make a cleaner and more resilient regional grid while minimizing stakeholder impacts and helping both regions meet their renewable energy needs.

The potential corridor more than pays for itself - Up to $780m per year in system and greenhouse gas reduction benefits for the first 2 gigawatts + Sufficient grid benefits to justify a $6-$8 billion investment, equivalent to the expected capital costs for the corridor + Related jobs and supply chain benefits of offshore wind deployment or the benefits of reduced marine impacts constitute additional value beyond this break-even proposition
The cross-border value proposition is mutual- Improves prospects for offshore wind development in both markets + Enables projects in each market to be delivered at a lower cost + Provides shared reliability and balancing benefits by strengthening the regional network + Minimizes cable landfalls and offshore cables to reduce stakeholder and environmental impacts and maximize coexistence with important maritime and fishing industries
An essential climate solution for both regions - Scalable to enable the volume of renewable energy needed to meet regional goals while reducing costs + Enhances the value of onshore generation and onshore transmission upgrades by boosting regional network connectivity + Unlocks key deep-decarbonization potential to both regional electricity grids and enables cost-effective green hydrogen opportunities
Maximizing the corridor’s value requires a standardized approach - Multiterminal high-voltage direct current (HVDC) designs provide a more scalable solution for integrating larger volumes of offshore wind into the regional grids + Using a mix of alternating current (AC) and direct current (DC) connections for different projects would drastically reduce the quantified system benefits and increase stakeholder impacts with negligible upside to ratepayers
