Ongoing outages and planned service interruptions

Description

October 23, 2025

In a few weeks, the open data on outages and planned service interruptions will only be available through a secure connection (HTTPS). This change is meant to enhance the security and integrity of the information provided.

Update your solution to continue accessing the data.

If you have any questions, write to the open data team.


Current outages. Hydro-Québec dataset that provides, in real time for each ongoing outage, the following information: 

  • the geographical location of the outage ;
  • the number of customers without electricity ;
  • the outage start time ;
  • the cause of the outage, when known ;
  • the estimated service restoration time.

Planned interruptions. Hydro-Québec dataset that provides the scheduled power interruptions in the coming days and, for each of them, the following information: 

  • the geographical location of the planned interruption ;
  • the number of affected customers ;
  • the start and expected restoration dates and times.

Files or services

Access to open data is made through queries to an API (for application programming interface). For more information on the topic, see the Données Québec website.

Current outages − API mode

This mode requires the use of three REST-type URLs.

First request: get the latest BIS file version (“time stamp”)

Click the URL below.

https://pannes.hydroquebec.com/pannes/donnees/v3_0/bisversion.json

This provides the Service Interruption Report (BIS) file number.

Example number:  "20180418084019".

Second request: get a JSON file containing the list of outages.

Append the obtained file number from the previous request to the end of the following URL.

URL : https://pannes.hydroquebec.com/pannes/donnees/v3_0/bismarkers{BIS_VERSION}.json

Example :
https://pannes.hydroquebec.com/pannes/donnees/v3_0/bismarkers20180418084019.json

The outage list specifies the outage date, the expected service restoration time, and the geographical coordinates (latitude and longitude) of the affected area.

Data excerpt associated with an outage: 

{ "messages": {}, "pannes": [

[ 2, "2018-04-19 10:13:03", "2018-04-19 11:15:00", "P", "[-74.03666800098304, 45.63760774828376]", "L", "4", "44", "9001", "" ],

Third request: download a KMZ file that provides the list of polygons representing outage sectors (approximate).

Append the obtained file number from the first request to the following URL.

URL : https://pannes.hydroquebec.com/pannes/donnees/v3_0/bispoly{BIS_VERSION}.kmz

Example:

https://pannes.hydroquebec.com/pannes/donnees/v3_0/bispoly20180418084019.kmz

Once the KMZ file is decompressed, open the KML files using a specialized tool such as Google Earth.

Upcoming planned interruptions − API mode

This mode requires the use of three REST-type URLs.

First request: get the latest AIP file version (“time stamp”)

Click the URL below.

https://pannes.hydroquebec.com/pannes/donnees/v3_0/aipversion.json

This provides the Planned Interruption Notice (AIP) file number.

Second request: get the list of upcoming planned interruptions (“aipmarkers”)

Append the received file number from the previous request to the following URL.

URL : https://pannes.hydroquebec.com/pannes/donnees/v3_0/aipmarkers{AIP_VERSION}.json

Result: Retrieval of a JSON file.
