PPL Corporation, an energy and utility holding company, has won approval from the Federal Energy Regulatory Commission (FERC) to acquire E.ON US.

This is the final regulatory approval needed for the acquisition of E.ON US, the parent company of Louisville Gas and Electric (LG&E) and Kentucky Utilities Company (KU), and PPL expects to close the transaction next month.

The acquisition previously received approvals from the Kentucky Public Service Commission, the Virginia State Corporation Commission and the Tennessee Regulatory Authority.

PPL has also received antitrust clearance for the acquisition from the Federal Trade Commission and the US Department of Justice.

E.ON US, through LG&E and KU, provides electricity service to approximately 941,000 customers, mostly in the state of Kentucky, with some customers in Virginia and Tennessee.

PPL owns or controls nearly 12,000MW of generating capacity in the US, sells energy in key US markets and delivers electricity to about four million customers in Pennsylvania and the UK.
