Power generation , supplying the Manic-5 hydro plant.|alt=A large concrete dam with multiple arches On December 31, 2013, Hydro-Québec Production owned and operated 61
hydro plants —including 12 of over 1,000 MW capacity — with 26 major reservoirs. These facilities are located in 13 of Quebec's 430
watersheds, including the
Saint Lawrence,
Betsiamites,
La Grande,
Manicouagan,
Ottawa,
Outardes, and
Saint-Maurice rivers. These plants provide the bulk of electricity generated and sold by the company. Non-hydro plants included the
baseload 675-MW gross
Gentilly nuclear generating station, a
CANDU-design reactor which was permanently shut down on December 28, 2012 the 660-MW
Tracy Thermal Generating Station, a heavy fuel oil-fired plant shutdown in March 2011 and two
gas turbine peaker plants, for a total installed capacity of 36,971 MW in 2011. Hydro-Québec's average generation cost was 2.11 cents per kWh in 2011. The company also purchases the bulk of the output of the 5,428-MW
Churchill Falls generating station in Labrador, under a long-term contract that would be extended under a new agreement to 2075, if the agreement is ratified. In 2009, Hydro-Québec bought the 60% stake owned by
AbitibiBowater in the
McCormick plant (335 MW), located at the mouth of the Manicouagan River near
Baie-Comeau, for C$616 million. In 2023, the energy sold by Hydro-Québec to its grid-connected customers in Quebec and exported to neighboring markets came almost exclusively from renewable sources. Hydro (98.53%) is by far the largest source, followed by wind (0.11%) and biomass,
biogas and waste (0.01%). TransÉnergie, Hydro-Québec's transmission division, operates the largest electricity transmission network in North America. It acts as the independent system operator and reliability coordinator for the
Québec interconnection of the
North American Electric Reliability Corporation system, and is part of the
Northeast Power Coordinating Council (NPCC). TransÉnergie manages the flow of energy on the Quebec network and ensures non-discriminatory access to all participants involved in the wholesale market. The non-discriminatory access policy allows a company such as
Nalcor to sell some of its share of power from Churchill Falls and from other sources on the open market in the State of New York using TransÉnergie's network, upon payment of a transmission fee. In recent years, TransÉnergie's ''Contrôle des mouvements d'énergie'' (CMÉ) unit has been acting as the reliability coordinator of the bulk electricity network for Quebec as a whole, under a bilateral agreement between the Régie de l'énergie du Québec and the
Federal Energy Regulatory Commission of the United States. TransÉnergie's high voltage network stretches over , including of , and a network of 514 substations. It is connected to neighbouring Canadian provinces and the United States by 17 ties, with a maximum reception capacity of 10,850 MW and a maximum transmission capacity of 7,994 MW.
Interconnections . The 1,250 MW back-to-back
HVDC tie links the Quebec grid with Ontario's
Hydro One network.|alt=A yellow-tinted room with wires and other metallic structures. The TransÉnergie's network operates asynchronously from that of its neighbours on the
Eastern Interconnection. Although Quebec uses the same 60
hertz frequency as the rest of North America, its grid does not use the same phase as surrounding networks. TransÉnergie mainly relies on
back to back HVDC converters to export or import electricity from other jurisdictions. This feature of the Quebec network allowed Hydro-Québec to remain unscathed during the
Northeast Blackout of August 14, 2003, with the exception of 5 hydro plants on the
Ottawa River radially connected to the Ontario grid at the time. A new 1250-MW back to back HVDC tie has been commissioned at the Outaouais substation, in
L'Ange-Gardien, near the
Ontario border. The new interconnection has been online since 2009 and the 315 kV line is fully operational since 2010.
Investments In 2011, TransÉnergie invested C$1.3 billion in capital expenditures, including C$460 million to expand its network. In addition to the new tie with Ontario, the company plans to build a new 1200-MW direct current link between the Des Cantons substation at
Windsor, Quebec in Quebec's
Eastern Townships and
Deerfield, New Hampshire, with an HVDC converter terminal built at
Franklin, New Hampshire. The US segment of the US$1.1 billion line, would be built by
Northern Pass Transmission LLC, a partnership between
Northeast Utilities (75%) and
NSTAR (25%). In order to go ahead, the project must receive regulatory approval in Quebec and the United States. The proposed transmission line could be in operation in 2015. According to Jim Robb, a senior executive from Northeast Utilities,
New England could meet one third of its
Regional Greenhouse Gas Initiative commitments with the hydropower coming through this new power line alone.
Distribution Hydro-Québec Distribution is in charge of retail sales to most customers in Quebec. It operates a network of of medium and
low voltage lines. The division is the sole electric distributor across the province, with the exception of 9 municipal distribution networks — in
Alma,
Amos,
Baie-Comeau,
Coaticook,
Joliette,
Magog,
Saguenay,
Sherbrooke and
Westmount—and the electric cooperative of
Saint-Jean-Baptiste de Rouville. Hydro-Québec Distribution buys most of its power from the 165-TWh
heritage pool provided by Hydro-Québec Production at 2.79¢/
kWh. The division usually purchases additional power by entering into long-term contracts after a public call for tenders. For shorter term needs, it also buys power from the neighboring systems at market prices. As a last resort, Hydro-Québec Production can also provide short-term relief. Supply contracts above and beyond the heritage pool must be approved by the ''Régie de l'énergie du Québec'' and their costs are passed on to customers. The division signed one
natural gas cogeneration agreement for 507 MW in 2003, three forest biomass deals (47.5 MW) in 2004 and 2005, and ten contracts for
wind power (2,994 MW) in 2005 and 2008, all with private sector producers. It also signed two flexible contracts with Hydro-Québec Production (600 MW) in 2002. Hydro-Québec Distribution is also responsible for the production of power in remote communities not connected to the main power grid. The division operates an off-grid hydroelectric dam serving communities on the
Lower North Shore and 23 small diesel power plants in the
Magdalen Islands, in
Haute-Mauricie and in
Nunavik.
Other activities Electric Circuit network In April 2011 the
government of Quebec published a plan to encourage the adoption of electric vehicles, setting a target of 25% of cars sold in 2020 to be electric. The plan also called for provincial utility company Hydro-Quebec to develop a strategy for the deployment of public charging infrastructure. This resulted in the creation of "The Electric Circuit" (), the largest public network of
charging stations for
electric vehicles in
Quebec. The first 30 charging stations were put into use in March 2012. The network's first 400V fast charger was installed in 2013. As of 2023, The Electric Circuit offers almost 3,500 public charging stations in Quebec and
eastern Ontario. IREQ operates on an annual research budget of approximately C$100 million and specializes in the areas of high voltage,
mechanics and thermomechanics, network simulations and calibration. Research conducted by scientists and engineers at IREQ has helped to extend the life of dams, improve
water turbine performance, automate network management and increase the transmission capacity of high voltage power lines. Another research centre, the ''Laboratoire des technologies de l'énergie'' (LTE) in Shawinigan, was opened in 1988 to adapt and develop new products while helping industrial customers improve their
energy efficiency. In the last 20 years, the institute has also conducted
research and development work towards the
electrification of ground transportation. Current projects include
battery materials, including innovative work on
lithium iron phosphate and nano-titanate, improved electric
drive trains and the effects of the large-scale deployment of electric vehicles on the
power grid. Projects focus on technologies to increase
range, improve performance in cold weather and reduce
charging time. Hydro-Québec has been criticized for not having taken advantage of some of its innovations. An electric
wheel motor concept that struck a chord with Quebecers, first prototyped in 1994 by Pierre Couture, an engineer and
physicist working at IREQ, is one of these. The heir to the Couture wheel motor is now marketed by
TM4 Electrodynamic Systems, a spin-off established in 1998 that has made deals with France's
Dassault and
Heuliez to develop an electric car, the
Cleanova, of which prototypes were built in 2006. Hydro-Québec announced in early 2009 at the
Montreal International Auto Show that its engine had been chosen by
Tata Motors to equip a demonstration version of its
Indica model, which will be road tested in
Norway.
Construction The Hydro-Québec Équipement division acts as the company's main contractor on major construction sites, with the exception of work conducted on the territory covered by the
James Bay and Northern Quebec Agreement, which are assigned to the
Société d'énergie de la Baie James subsidiary. The construction of a complex of four hydroelectric generating stations on the Romaine River () began on May 13, 2009. The plants have been completed as of 2022 and have added a total of 1 550 MW of power. In his March 2009
inaugural speech, Quebec Premier
Jean Charest announced that his government intends to further develop the province's hydroelectric potential. The call for further development of hydroelectric and other renewable generating capacity has been implemented in the company's 2009-2013 strategic plan, released on July 30, 2009. Hydro-Québec plans capacity upgrades at the
Jean-Lesage (120 MW) and
René-Lévesque (210 MW) stations and a third unit at the SM-3 plant (440 MW). The company will also conduct technical and environmental studies and undertake consultations with local communities to build new facilities on the
Little Mecatina (1,200 MW) and
Magpie (850 MW) rivers on the North Shore, and revive the Tabaret project (132 MW) in the
Abitibi-Témiscamingue region, in western Quebec.
International ventures Hydro-Québec first forays outside its borders began in 1978. A new subsidiary, Hydro-Québec International, was created to market the company's know-how abroad in the fields of distribution, generation and transmission of electricity. The new venture leveraged the existing pool of expertise in the parent company. During the next 25 years, Hydro-Québec was particularly active abroad with investments in electricity transmission networks and generation: Transelec in
Chile, the
Cross Sound Cable in the
United States, It briefly held a 17% share in SENELEC,
Senegal's electric utility, when the Senegalese government decided to sell part of the company to a consortium led by the French company Elyo, a subsidiary of
Group Suez Lyonnaise des Eaux, in 1999. The transaction was canceled in 2000 following the election of president
Abdoulaye Wade. Also in 1999, Hydro-Québec International acquired a 20% stake in the Meiya Power Company in
China for C$83 million. The company's expertise was sought by several hydroelectric developers throughout the world, including the
Three Gorges Dam, where Hydro's employees trained Chinese engineers in the fields of management, finance and dams. Hydro-Québec gradually withdrew from the international business between 2003 and 2006, and sold off all of its foreign investments for a profit. Proceeds from these sales were paid to the government's Generations Fund, a trust fund set up by the province to alleviate the effect of public debt on future generations. In 2022, Hydro-Québec, through its US Subsidiary HQI US Holding, acquired Great River Hydro, LLC. for the sum of US$2.2 billion. == Environment ==
