Demand Opportunity Service (DOS) formerly the Energy Storage Tariff Working Group

Application Filed

An application for approval of Updates to Rate DOS was filed with the Alberta Utilities Commission (AUC) on April 23, 2024. For information regarding the application, or on the status of the proceeding, please visit the AUC’s eFiling site and go to Proceeding 28989. The AESO would like to thank stakeholders for the time, effort, and resources they contributed to this extensive and thoughtful stakeholder engagement. Feedback received from diverse stakeholders informed each step of this engagement and resulted in pivots in path and approach along the way. This application is the culmination of a concerted effort to seek broad stakeholder alignment on what incremental improvements to the tariff would strike a reasonable balance of interests and be of value during this period while the market awaits further policy direction.

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.
