American Municipal Power (AMP) continued its criticism of PJM’s grid spending, grilling utility officials during a marathon TEAC meeting.

The PJM Board of Managers authorized $348 million in transmission projects, irking American Municipal Power.

PJM told members of the Transmission Replacement Process Senior Task Force they must agree on a common definition of end-of-life facilities.

More than half of the $24.3 billion in transmission projects in PJM since 2012 were unneeded to comply with reliability requirements, according to AMP.

An update on the PJM Transmission Replacement Processes Senior Task Force at the end of the Markets and Reliability Committee meeting became contentious.
