Consultation has concluded

Engagement Outcomes

In Decision 28989-D01-2024, dated July 31, 2024, the AUC approved the AESO's application. Rate DOS and related amendments to the ISO tariff and definitions will come into effect February 1, 2025. The AESO thanks all stakeholders involved, ether in the working group, or otherwise for their invaluable contributions to this consultation.

Background

Following the conclusion of the Energy Storage Tariff Working Group sessions in September 2023, the AESO posted a Stakeholder Background document which contained additional information on the work to date and an outline of next step options available. Feedback was sought from stakeholders by November 17, 2023. The feedback received indicated that there was broad support for an update to the Demand Opportunity Service (DOS) Rate. A good deal of work had already been done to revise the DOS rate and terms and conditions through the working group, however a few items still required additional discussion. To further the conversation, the AESO commenced a focused consultation on updates to the DOS Rate encouraging stakeholders to reach out to discuss potential changes and improvements. The AESO has been meeting with interested and impacted stakeholders since mid-December to advance the discussion on the DOS rate, term and business case requirements.
