Hydro Quebec transmission expansion aims to move surplus hydroelectric capacity from record reservoirs to the US grid via new interties, increasing exports to New England and New York amid rising winter peak demand.
Key Points
A plan to add capacity and intertie links to export surplus hydro power from Quebec's reservoirs to the US grid.
✅ 245 MW added in 2021; portfolio reaches 37,012 MW
✅ Reservoirs at unprecedented levels; export potential high
✅ Lacks US transmission; working on new interties
Hydro Quebec plans to add an incremental 245 MW of hydro-electric generation capacity in 2021 to its expansive portfolio in the north of the province, while Quebec authorized nearly 1,000 MW for industrial projects across the region, bringing the total capacity to 37,012 MW, an official said Friday
Quebec`s highest peak demand of 39,240 MW occurred on January 22, 2014.
A little over 75% of Quebec`s population heat their homes with electricity, Sutherland said, aligning with Hydro Quebec's strategy to wean the province off fossil fuels over time.
The province-owned company produced 205.1 TWh of power in 2017 and its net exports were 34.4 TWh that year, while Ontario chose not to renew a power deal in a separate development.
Sutherland said Hydro Quebec`s reservoirs are currently at "unprecedented levels" and the company could export more of its electricity to New England and New York, but faces transmission constraints that limit its ability to do so.
Hydro Quebec is working with US transmission developers, electric distribution companies, independent system operators and state government agencies to expand that transmission capacity in order to delivery more power from its hydro system to the US, Sutherland said.
Separately, NB Power signed three deals to bring more Quebec electricity into the province, reflecting growing regional demand.
The last major intertie connection between Quebec and the US was completed close to 30 years ago. The roughly 2,000 MW capacity transmission line that connects into the Boston area was completed in the late 1990s, according to Hydro Quebec spokeswoman Lynn St-Laurent.
