The cost estimate for MISO’s and SPP’s package of 345-kV lines meant to facilitate the interconnection of generation at the seams has nearly doubled, the RTOs have said in the past week.

A panel of experts discussing NERC’s Summer Reliability Assessment emphasized the need for teamwork in benefiting from increased interregional transmission.

Parties filing comments with FERC on expanding interregional transfer capability mostly supported the concept, though opinions were split on how to get there.

Sen. Joe Manchin called on colleagues to put politics aside and hammer out a bipartisan bill to accelerate permitting of energy and transmission projects.

MISO released details about how it will administer cost allocation on the $1 billion Joint Targeted Interconnection Queue portfolio of 345 kV projects.

The cost of transmission congestion doubled in organized electricity markets between 2020 and 2021, rising by billions of dollars, according to Grid Strategies.

MISO and SPP said DOE has signaled that grid operators and their state commissions can move forward with a full application for funding from the GRIP program.

Electric transmission projects move too slowly, Maryland Public Service Commission Chairman Jason Stanek said at NARUC's Winter Policy Summit on Monday.

SPP’s state commissioners have approved staff’s proposed cost allocation for the projects in its Joint Targeted Interconnection Queue study portfolio.

ALLETE and Grid United are teaming up to build a first-of-its-kind line that would span across interconnections and through three electric regions.
