Project summary
Why?
- Pursue the development of wind potential
- Improve grid resilience and reliability in the face of increasingly intense weather events.
How?
- Phase 1: Build a 315-kV substation and approximately 260 km of 315-kV lines.
- Phase 2: Build a 315-kV substation and approximately 175 km of 315-kV lines.
When?
- Phase 1: 2034
- Phase 2: 2036
Project optimization continues
Based on an in‑depth technical analysis, the voltage of the new transmission line between Appalaches substation (in Saint‑Adrien‑d’Irlande) and the Bas‑Saint‑Laurent region will now be 315‑kV instead of 735‑kV as initially planned.
Given the existing transmission infrastructure, a 315‑kV line will offer more flexibility for regional electricity generation to be integrated on the grid without reducing transmission capacity. All other project parameters remain unchanged.
