MISO and SPP regulators are close to asking the RTOs for improvements to transmission operations on their seam as their market monitors wind down a study.

The Organization of MISO States continues to signal its grid operator that regulators are ready for dynamic transmission line ratings in the footprint.

Some regulators aren’t convinced about merging MISO’s transmission planning with interconnection studies, a move some say could improve cost effectiveness.

MISO could face a generation shortfall as early as 2022, according to the annual survey by the Organization of MISO States and the RTO.

MISO’s Steering Committee is considering proposing a rule that would require consultants to identify clients they represent when participating in stakeholder meetings.

SPP’s Market Monitor said MISO and SPP must rethink some of their fees and practices before rolling out coordinated transaction scheduling across the seam.

MISO is stepping up efforts to understand how markets will function with the possible participation of heavy concentrations of distributed energy resources.

MISO will focus on the northern portion of its footprint with two supplemental studies to be included in its 2020 Transmission Expansion Plan cycle.

Regulators in MISO and SPP states are looking into the RTOs’ inability to develop interregional projects intended to relieve congestion across seams.
