Despite the ongoing shift to renewables, the Eastern Interconnection has sufficient inertia to maintain system frequency for at least the next five years.

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.

Ten transmission upgrades have been placed in service in New England since October, ISO-NE engineer Jon Breard told the RTO’s Planning Advisory Committee.

The city of Wilmington, Del., will be retired as the meeting site for the Markets and Reliability and the Members committees, PJM stakeholders agreed.

MISO's Steering Committee instructed the Planning Advisory Committee to revisit non-transmission owners operating storage-as-transmission assets.

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

MISO will rely on the same set of futures for the third straight year when it evaluates transmission projects in its 2020 Transmission Expansion Plan.

MISO released draft Tariff language that would allow energy storage resources to compete for projects in the RTO’s annual Transmission Expansion Plan.
