PPL Corporation and Riverstone Holdings LLC announced a definitive agreement to combine their merchant power generation businesses into a new stand-alone, publicly traded independent power producer. The new company, which will own and operate 15,320 MW of generating capacity, will be called Talen Energy Corporation. Based on current generating capacity statistics, Talen Energy would be the third-largest investor-owned IPP in the nation. Under the terms of the agreement, at closing, PPL Corporation will spin off PPL Energy Supply, the parent company of PPL Generation, and PPL EnergyPlus, to shareowners of PPL and then immediately combine that business with Riverstone's generation business to form Talen Energy Corporation, an independent publicly traded company expected to be listed on the New York Stock Exchange. The transaction is subject to approval by the Nuclear Regulatory Commission, the Federal Energy Regulatory Commission and others.
