Manitoba Hydro
Manitoba Hydro is the provincial Crown corporation that generates, transmits, and distributes electricity and distributes natural gas across Manitoba, Canada — "Manitoba's publicly owned electricity and natural gas supplier" in its own words, serving 632,117 electric customers and 300,789 natural gas customers, and trading electricity into wholesale markets across the Midwestern U.S. and Canada. It is a vertically integrated monopoly in a province with no retail competition, no independent system operator of its own, and no consumer energy data mandate: Ontario's Green Button regulation (O. Reg. 633/21) binds Ontario distributors only, Australia's Consumer Data Right does not reach Canada, and the Green Button Alliance states plainly that it has "no information about Green Button deployments in Manitoba." Manitoba Hydro also has no advanced metering infrastructure — its 2006-2009 smart meter pilot was not continued — so there is no interval consumption data for a consumer API to serve in the first place. The API posture is therefore the inverse of a mandated utility: consumer data is entirely closed, reachable only by the customer through a login at account.hydro.mb.ca, while grid and system data is genuinely open and anonymous. Manitoba Hydro runs a public ArcGIS Online organization whose current and planned power outage layers are queryable without a key over both the Esri ArcGIS REST API and OGC WFS 2.0.0, refreshed every five minutes; an on-domain ArcGIS Server REST directory at maps.hydro.mb.ca; and a live KISTERS hydrological monitoring application whose station and time-series JSON at hydro.mb.ca is served anonymously and was observed carrying same-day readings. None of it is documented as an API. There is no developer portal, no API keys, no OpenAPI, and no terms of use for data reuse — the open surface exists as a by-product of public map publishing rather than as an API program.
Manitoba Hydro publishes 4 APIs on the APIs.io network. Tagged areas include Energy, Canada, Utilities, Electricity, and Gas.
Manitoba Hydro’s developer surface includes authentication, code examples, documentation, signup flow, support, engineering blog, and 17 more developer resources.

description: A hosted Esri feature service published by Manitoba Hydro's ArcGIS Online organization (org id QoeQkfdOG126FqSi,
org name "Manitoba Hydro", item owner dcarpenter@hydro.mb.ca) carrying live unplanned power outage polygons. The item
is shared publicly and was queried anonymously with no key, token, or registration — an anonymous returnCountOnly query
returned 8 active outages at review time. Layer 0 "MH Current Power Outages" exposes OUTAGE_ID, OUTAGE_TYPE, TIME_OF_OUTAGE,
NUM_CUST_NOPOWER, NUM_CUST_NOPOWERTXT, ETR, CAUSE, SUBCAUSE, CREW_STATUS, FIELD_VERIFIED_ETR, DATA_LAST_UPDATE and AREA.
Service capabilities are Query only. The same data is also published as an OGC WFS 2.0.0 endpoint whose GetCapabilities
document was retrieved anonymously. Manitoba Hydro publishes no documentation, no terms of use, and no rate limits for
this surface — it is a public map layer that behaves as an API.

outage areas. The item description states the layer "contains planned power outages and the area that will be impacted.
Attributes include the scheduled start and end date/time for each outage. This data is updated every 5 minutes." Queried
anonymously with no credentials, an unfiltered count returned 48 planned outages at review time. Layer 0 "MH Planned Power
Outages" exposes ORDER_ID, ORDER_LAST_UPDATED, ORDER_STATUS_DESCRIPTION, ORDER_CAUSE, ORDER_TYPE, ORDER_DESCRIPTION, DEVICE,
DEVICE_ADDRESS, CSC, SCHEDULED_START_TIME, SCHEDULED_END_TIME, DATA_LAST_UPDATE and NUM_CUST_NOPOWERTXT. A parallel OGC

description: An ArcGIS Server 10.91 REST services directory hosted on Manitoba Hydro's own domain at maps.hydro.mb.ca, readable
anonymously. The root listing returned nine folders (ARL, ConTrack, DISTAPPS, GDS, JUTA, LEA, Locators, ReferenceData,
Utilities); most are empty to an anonymous caller, but ReferenceData/MH_AdminBoundaries is fully readable and exposes
three query-capable layers — MH_CustomerServiceCentres (19 features), MH_LocateAreas and MH_StationAreas. The site root
itself returns HTTP 403; only the /arcgis/rest/services tree responds. Manitoba Hydro publishes no documentation, index,
or terms for this host — it is recorded here because it is a real, on-domain, anonymously queryable API surface, not because
it is offered as one.

description: Manitoba Hydro's near-real-time hydrological monitoring application, a KISTERS WISKI Web Public deployment
documented on hydro.mb.ca and reachable at https://www.hydro.mb.ca/hydrologicalData/static/. The application is documented
for humans; its data files are not documented at all, but they are served anonymously as JSON and were verified live —
station metadata (169 gauging stations with river, catchment, latitude, elevation and station number fields), a layer
index of 15 monitored parameters (Water Level, Water Temperature, Air Temperature, Precipitation, Snow Depth, wind speed,
direction, gust and peak variants, Relative Humidity, Atmospheric Pressure), and per-parameter observation files. The
Water Level file returned 158 stations with readings timestamped the same day as this review. Manitoba Hydro's own page
states the readings come from gauging stations managed by Manitoba Hydro, the Water Survey of Canada and Manitoba Water
Stewardship, that data are "preliminary and are being transmitted automatically without verification or review for quality
assurance," and that Manitoba Hydro "does not warrant the quality, accuracy, or completeness of any information." There
is no API documentation, no versioning, and no stated licence. Note that an older parallel tree at /hydrologicalData/data/
is still served but is frozen at February 2021 readings; only the /static/ tree is current.
