    Energy Storage Long-term Markets Participation

    Introduction and purpose

    This initiative is part of the long-term implementation of the energy storage integrated plan as detailed in the Energy Storage Roadmap.

    The purpose of this initiative is to enable energy storage assets to fairly access markets for which they meet the technical requirements through the development or revisions to AESO authoritative documents (ADs) and information documents. ISO rules for participation in the energy and ancillary services markets will: provide clarity for energy storage assets given their unique operating characteristics; support the safe, reliable and economic operation of the Alberta Interconnected Electric System; and, ensure the FEOC operation of the markets. This initiative builds upon the work completed for short-term implementation of energy storage integration which provides energy storage projects with clarity for participation in the markets under the existing ISO rules.

    Working with stakeholders, the AESO will outline and evaluate the options for energy storage participation in the energy and ancillary service markets. and if recommended, ADs will be reviewed and updated to foster investor understanding of market expectations to aid them when making future decisions.
