Energy Storage Advisory Group

Resource Acquisition

The Energy Storage Advisory Group will perform an advisory role to support and assist the IESO in evolving policy, rules, processes and tools to better enable the integration of storage resources within the current structure of the IESO-administered market. The IESO will look to the advisory group to carry out the following activities:

  • Identify potential obstacles to the fair competition for energy storage resources and propose mitigating strategies, where appropriate. This support includes reviewing a list of identified obstacles for completeness, and reviewing criteria and principles to help guide the identification of obstacles to the fair competition of storage and creation of mitigating strategies. This review was the immediate focus of the Storage Advisory Group.
  • Provide input to the IESO’s work plan and/or list of priorities to address storage related issues and opportunities within the current IESO-administered markets, including tools and operational arrangements.  
  • Advise, consult and coordinate discussions on issues which may affect storage participation in the existing IESO-administered markets. 

 All comments, enquiries and requests for membership in this group can be directed to engagement@ieso.ca.

On December 19, 2018, the IESO released its report, Removing Obstacles for Storage Resources in Ontario, which recommends solutions to address the primary barriers preventing the fair competition of energy storage resources.
