FERC is set to vote on its long-awaited proposed rule on transmission planning and cost allocation for regional lines at a special open meeting May 13.

The NEPOOL Transmission Committee voted to approve a proposal by ISO-NE and the New England States Committee on Electricity to create a new process to facilitate transmission investments that address state-identified, long-term needs associated with the clean energy transition.

MISO’s conceptual, $20 billion, 765-kV transmission suggestion took top billing at Board Week, with some members asserting MISO has even more transmission to plan if it wants to meet the future confidently.

FERC appears to be nearing completion on its transmission planning rulemaking, with cost allocation rules and the federal ROFR among the issues at stake.

FERC commissioners urged SPP to conduct a stakeholder process to vet a proposal to socialize “byway” transmission on a case-by-case basis.

Weeks after the nearly $2 billion Joint Targeted Interconnection Queue (JTIQ) transmission portfolio was awarded a $465 million Department of Energy grant, MISO and SPP are switching their proposed cost allocation for the projects.

FERC granted in part, and dismissed in part, Ponderosa Power’s complaint against NorthWestern’s proposal to assign roughly $30 million in network upgrade costs to the wind farm developer.

A group of renewable developers lodged a complaint at FERC over MISO’s pursuit of a smaller system impact threshold on interconnecting generation.
