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.
Hydro-Québec publishes 2 APIs on the APIs.io network: Open Data Explore API v2.1 and Open Data Explore API v2.0. Tagged areas include Energy, Canada, Utilities, Electricity, and Grid.
Hydro-Québec’s developer surface includes authentication, developer portal, documentation, API reference, getting-started guide, support, engineering blog, and 30 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Energy & Utilities regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

description: Read-only REST API over Hydro-Québec's 26 public open datasets — catalog search, dataset metadata, record query
with the Opendatasoft Query Language (ODSQL), facets, attachments, and bulk exports to CSV, Parquet, GPX and DCAT. Covers
Québec electricity demand and generation, imports and exports, ongoing outages and planned service interruptions, direct
GHG emission factors, hydrometric and weather history, winter peak demand events, and vegetation control planning. Verified
callable anonymously with no API key (HTTP 200, 26 datasets returned, 2026-07-27); an optional apikey query parameter
is supported for authenticated requests. Data is licensed CC BY-NC 4.0 (attribution, non-commercial). Market and grid
data only — no individual customer consumption is exposed.
