The Organization of MISO States issued a set of principles intended to guide the RTO’s approach to long-term transmission planning.

Stakeholders gave MISO leadership mixed signals on what they expect from seams policy, though they agreed the RTO shouldn’t strive for exacting consistency in how it deals with different neighbors.

Transmission developers, planners and regulators gathered at the Key Bridge Marriott in Arlington, Va., for Infocast’s annual Transmission Summit East.

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

SPP and MISO staff and stakeholders recommended performing a coordinated system plan in 2019-20 to study 6 possible sites for transmission projects.

CAISO is exploring ways to exchange more low-carbon electricity with the Pacific Northwest, while WestConnect looks to absorb exports from California during overgeneration.

Energy security continues to be a critical reliability issue for New England as ISO-NE develops its 2019 Regional System Plan.

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.

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.
