SPP’s state regulators recently agreed on revisions to a package of recommendations that would improve operations along the RTO’s seam with MISO.

Texas Public Utility Commission Chair DeAnn Walker facilitated the Regional State Committee’s modifications to the document, which prioritizes resolving rate pancaking and adds a category for smaller interregional projects. (See RSC Keeps MISO Liaison Committee Alive.)

The RSC, meeting on Feb. 12 shortly before severe winter weather overwhelmed many of its members’ states, agreed that rate pancaking and smaller interregional projects should remain their two top priorities.

The regulators also agreed that the RSC-Organization of MISO States Seams Liaison Committee (SLC) should create a working group focused on inventorying the different types of rate pancaking along the MISO-SPP seam and sided with the SLC’s recommendation that a survey be conducted of transmission owners and other stakeholders to measure interest in studying the issue.

“Creating that inventory is important,” Kansas Corporation Commissioner Andrew French said. “It’s important to get feedback from the TOs and other stakeholders. It’s not just TOs experiencing those issues.”

The SLC has said the working group should comprise RSC and OMS members and an equal number of other stakeholders chosen by the two regulatory groups.

Walker, the RSC’s lead on the SLC, was to send the revised document to OMS Executive Director Marcus Hawkins.
