PPL and Riverstone have agreed to satisfy market power concerns over the spinoff of their generation into Talen Energy by making only cost-based offers for the more than 650 MW that they will keep in eastern PJM.

Duke Energy and Exelon should be among the companies barred from acquiring any generation divested by PPL as part of its Talen Energy spinoff, the IMM told FERC.

PPL’s plan to spin off its generation into Talen Energy needs additional mitigation to address local market power concerns, PJM’s market monitor told FERC.
