Ottawa Funds PEI–NB Cable Prep as Maritime Premiers Sign an Electricity Pact

On the same day in Charlottetown, New Brunswick got two pieces of electricity news that belong together: federal money to prepare new underwater cables to Prince Edward Island, and a three-province memorandum of understanding to plan the Maritime grid as a region.

Two new cables, $5.9 million to start

Ottawa is putting $5.9 million into pre-development work on the Prince Edward Island–New Brunswick Interconnection Expansion Project — two new 200 MW, 138 kV submarine cables plus transmission and substation upgrades on both sides of the Northumberland Strait.

The money flows to the PEI Energy Corporation from the federal Smart Renewables and Electrification Pathways program. It pays for engineering studies, marine surveys, environmental assessments, Indigenous and stakeholder engagement, regulatory work, and preliminary route and substation design — not the full build. Construction groundwork is targeted to begin by 2028, according to the joint federal–provincial materials. The total project cost has not been published; Premier Rob Lantz told CBC the exact scope will firm up during pre-development.

PEI already depends on four subsea cables to New Brunswick. The Cape Tormentine–Borden-Carleton pair was replaced in 2017; the older Murray Corner–Richmond Cove pair dates to the late 1970s and is nearing end of life. Premier Susan Holt, welcoming the federal investment, cast New Brunswick as the Maritimes’ “energy hub” and stressed securing and strengthening interties with PEI.

A Maritime electricity MOU

Also on July 23, Holt signed an MOU with Nova Scotia Premier Tim Houston and PEI’s Lantz — with Natural Resources Canada as a partner — on Maritime regional electricity co-operation and system integration.

The agreement is planning infrastructure, not a new generating station. The provinces will develop a Maritime Regional Resource and Transmission Roadmap, weigh closer operational co-ordination, and study options that include a regional balancing authority and a possible Maritime Independent Electricity System Operator (MIESO). GNB’s release targets a roadmap and implementation plan by spring 2027; the fuller MOU text phases work through fall 2026 and spring 2027. Utilities expected to feed the process include NB Power, NS Power, Maritime Electric, and IESO Nova Scotia.

Holt’s public framing leaned on New Brunswick’s “leadership in nuclear energy” and stronger electricity interties — language that positions the province as a regional hub without announcing a new reactor or a new NB–NS line in this package.

Why it is a tech story

Cables and control rooms are not startups, but they are the substrate every data centre, factory, and electrification plan eventually hits. For New Brunswick, the July 23 package is concrete on the PEI interconnect path and procedural on the regional market design — both of which will decide how much spare capacity exists when the next large load asks for a hookup.
