Standardized DER Test Cases

The IESO has developed a set of standardized DER test cases to assess the performance of distributed energy resources (DER), including aggregations of DERs, during the provision of various grid services. The test cases are applicable to pilot DER projects receiving IESO support (financial, in-kind or other).

The standardized DER test cases enable the IESO to clearly communicate expectations about project evaluation to external organizations exploring opportunities to engage with us on DER pilots.

DER Test Cases are available for Operating Reserve, Targeted Ramp, Demand Response and Regulation Service. Worksheets for the DER Test Plan and the DER Test Cases are available:

If you have questions about a test case please contact the GIF team.
