New Brunswick / Nova Scotia Interprovincial Transmission Line Project
At NB Power, we’re taking the steps that are necessary to transition as cost-effectively and efficiently as possible to meet government-mandated goals to get off-coal by 2030 as well as meet net-zero energy production targets.
While NB Power maintains a robust transmission and distribution system, upgrades are required to our grid to ensure it can reliably manage the integration of more renewable energy. Customers’ energy needs are also increasing as technology and electrification are becoming an even bigger part of their day-to-day lives.
Our Strategic Plan is guiding us as we respond to these evolving needs and helping us make the necessary decisions as we work to modernize our grid. As part of this plan, we’re increasingly seeking out new or expanding on existing partnerships to help us achieve our goals.
Here in Atlantic Canada, our neighbours are facing the same challenges and the same demands as we are. By working together, we can leverage our existing systems and find new opportunities to provide greater reliability and energy security, benefitting customers in all of the East Coast provinces.
Project Background
The New Brunswick / Nova Scotia Interprovincial Transmission Line Project consists of a new 345 kilovolt (kV) transmission line from New Brunswick to Nova Scotia to complement new clean energy developments and enable efficient imports and exports of electricity throughout the Atlantic provinces.
Currently, there is one 345 kV transmission line supplying electric power into Nova Scotia from New Brunswick.
The new transmission line would be approximately 265 km in length which will be developed in two phases.
Phase 1 of the New Brunswick / Nova Scotia Interprovincial Transmission Line Project would be a new 345kV transmission line approximately 65 km in length, running from an expanded terminal near Salisbury to an expanded terminal in Memramcook, and then to the New Brunswick-Nova Scotia border where it connects with Nova Scotia Power’s line through to the Onslow terminal.
Phase 2 of the New Brunswick / Nova Scotia Interprovincial Transmission Line Project would be a new 345kV transmission line approximately 200 km in length, running from existing terminals at Point Lepreau, Coleson Cove and Norton which will be expanded to accommodate the new electrical infrastructure which will run adjacent to existing transmission lines between Point Lepreau to Salisbury.
