AESO

The Alberta Electric System Operator (AESO) is the independent, not-for-profit system and market operator for Alberta's electricity system — a statutory body created under Alberta's Electric Utilities Act that dispatches generation and operates the Alberta Interconnected Electric System twenty-four hours a day for roughly five million Albertans, plans the transmission system, administers grid connections, and runs Alberta's energy-only wholesale market including price settlement and market rules. It sits in the middle of the value chain: it does not own generation, wires or retail customers, it clears the pool, publishes the Pool Price, and holds the market-wide operational data every generator, retailer and trader in Alberta depends on. Its API posture is unusually clean for the sector and is the exact opposite of a compliance story — there is no mandate on AESO at all. Alberta has no Consumer Data Right, no Green Button regulation (that is Ontario's, by regulation, and Nova Scotia's), and no consumer energy-data obligation of any kind, and AESO holds no retail customer usage or billing data, so the consumer-data half of this sector simply does not exist here. What AESO publishes voluntarily is a genuinely open market-data surface in two layers: the legacy Energy Trading System report servlets at ets.aeso.ca, which return real CSV and HTML market reports — current supply and demand, pool price, system marginal price, daily averages, outages — anonymously with no key, no account and no licence click-through; and a modern Azure API Management gateway at apimgw.aeso.ca fronting fourteen documented JSON APIs whose full reference, operations, schemas and OpenAPI export can be read anonymously from the public developer portal, and whose keys are issued self-serve — email confirmation, subscribe to the single "AESO Public API" product, keys generated instantly, no approval step. Authentication is a single API-KEY request header (or a subscription-key query parameter). The one real friction is legal rather than technical: AESO's site terms permit non-commercial, personal or educational use only, and any other use requires written permission.

AESO publishes 14 APIs on the APIs.io network, including Pool Price Report API, System Marginal Price Report API, Current Supply Demand API (v2), and 11 more. Tagged areas include Energy, Canada, Alberta, Electricity, and Energy Markets.

AESO’s developer surface includes authentication, documentation, signup flow, support, engineering blog, API reference, getting-started guide, and 28 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/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.

    click-through. Confirmed live and anonymous on 2026-07-27: CSDReportServlet returned HTTP 200 with the Current Supply
    Demand report (Alberta Total Net Generation 10,430 MW, Net Actual Interchange 241 MW, Alberta Internal Load 10,189 MW,
    plus the generation mix by fuel — cogeneration, wind, combined cycle); SMPriceReportServlet returned HTTP 200 with the
    hourly Pool Price series including the thirty-day rolling average and AIL demand; DailyAveragePoolPriceReportServlet returned
    HTTP 200 with daily on-peak and off-peak averages; RealTimeShiftReportServlet, ActualForecastWMRQHReportServlet and HistoricalPoolPriceReportServlet
    all returned HTTP 200. There is no OpenAPI, no schema and no formal reference for this surface — AESO documents the report
    URLs on its Market and System Reporting page and nothing more — so it is recorded here as a verified public data surface
    rather than as a specified API.'
