MISO is not resting after FERC recently accepted its transmission cost allocation plan, promising more such work on long-term and interregional projects.

SPP may have been incorrectly charging transmission customers for their use of certain facilities, GridLiance High Plains says.

Development of new high-voltage transmission lines could provide benefits for the U.S. electricity system, FERC said in a recent report.

FERC rejected transmission customers’ complaint over MISO’s seven-year-old cost allocation plan for baseline reliability projects.

The PJM MIC endorsed an initiative to update the RTO’s business rules to accommodate co-located generation and energy storage hybrid resources.

PJM told the Planning Committee it stands behind seeking approval of a regional market efficiency project process without developing cost allocation rules.

MISO is mounting a third attempt to gain FERC approval to overhaul the cost allocation design for economic transmission projects after previous rejections.

LS Power is challenging PJM over a new regional targeted market efficiency project process and AEP's proposed storage-as-transmission asset project.

FERC approved PJM’s updated annual cost responsibility assignments for projects in the Regional Transmission Expansion Plan over the objections of ODEC.

In a trio of orders, FERC again rejected challenges to PJM’s transmission cost allocation methods in a long-running dispute in New Jersey.
