The SPP Regional State Committee approved a recommendation to engage the RTO’s MMU and the MISO Monitor to conduct a joint analysis on seams issues.

SPP and MISO are reviewing a draft of their 2019 Coordinated System Plan, which will determine the need for any interregional transmission projects.

SPP’s Regional State Committee endorsed a policy white paper intended to ensure all net peak demand is carrying the appropriate capacity.

The SPP-MISO Joint Planning Committee has voted to begin a new coordinated system plan this year, SPP staff told the RTO’s Seams Steering Committee.

SPP told stakeholders it will have to make decisions on potential interregional projects in the 2019/20 coordinated system plan before hearing from MISO.

State regulators are bringing in the MISO and SPP market monitors to help solve seams issues between the two RTOs.

MISO and SPP told stakeholders that there is “more support than not” for the RTOs to conduct a joint study of interregional transmission projects in 2019.

An SPP group has been unable to reach a consensus on possible revisions to cost-allocation rules for wind-rich areas and may table their year-long review.

State regulators in MISO and SPP are making progress on the seams issues that continue to vex the RTOs, but much work remains, stakeholders learned.

SPP’s interregional relations staff shared with the Seams Steering Committee their strategic vision for seams efforts through 2021.
