Energy Trading System (ETS)
The Energy Trading System (ETS) is used to participate in the wholesale energy market. Market participants use ETS to enter energy supply offers and demand bids. The system also includes metering data, settlement and billing.
Accessing ETS
Participants are required to apply for and receive a digital certificate to gain access to the confidential information residing on the ETS. A digital certificate assures that the website you access is the secure AESO ETS. It also allows the ETS to recognize authorized system users and allow access to appropriate information. Application form must be sent in by an authorized corporate contact.
For security integrity, certificates require renewal on or before the anniversary date of the installation. DigiCert PKI Client will automatically notify you 5 days prior to the annual renewal date.
We encourage market participants to review the following documents as it will help familiarize themselves with digital certificates and ETS. These materials are also a great reference source to come back to anytime you have questions.
