Hydro-Québec is the government-owned Crown corporation that generates, transmits and distributes almost all of the electricity consumed in Québec, Canada — a vertically integrated, near-monopoly utility running one of the largest hydroelectric fleets in the world and serving roughly 4.6 million customer accounts across the province. It sits at every point of the value chain at once, as generator, transmission owner, distributor and retailer, plus a cross-border exporter into the New England and New York markets. Its API posture is a clean split. Market and grid data is genuinely open — a public Opendatasoft-powered portal at donnees.hydroquebec.com serves 26 datasets (electricity demand and generation, imports and exports, outages, GHG emission factors, hydrometric and weather data, winter peak demand events, vegetation control) through a documented, anonymously callable REST API with a machine-readable OpenAPI 3.0.3 description and a DCAT catalog export, licensed CC BY-NC 4.0. Consumer data is closed — there is no documented customer-facing API, no Green Button Download My Data or Connect My Data service, and no third-party consent flow; a customer's own usage is reachable only by logging into the Espace client web portal. Québec has no consumer energy data right. Ontario's Green Button regulation (O. Reg. 633/21 under the Electricity Act, 1998) is province-specific and does not bind Hydro-Québec, and Canada has no national equivalent to Australia's Consumer Data Right energy regime. Open market data, closed consumer data, no mandate.
