2022 ISO Tariff Modernization Application Arguments

In Proceeding 27864, the Alberta Electric System Operator (AESO) and interveners submit their arguments before the Commission for and against the AESO’s 2022 Independent System Operator (ISO) Tariff Modernization Application. In general, intervenors oppose the AESO’s proposed revisions to System Access Service Requests (SASRs) and Generating Unit Owner’s Contribution (GUOC) policies.

Therefore, this article only discusses the SASR and GUOC arguments.
