Overview
LG&E and KU Energy is an American energy utility holding company headquartered in Louisville, Kentucky. Its operating businesses are Louisville Gas & Electric (LG&E), Kentucky Utilities (KU), and Old Dominion Power (ODP), with ODP operating as a subsidiary of Kentucky Utilities. The group serves utility customers in Kentucky and, through Old Dominion Power, Virginia. The company was formed in 1998 through the combination of two established utility groups. LG&E Energy, the parent of Louisville Gas & Electric, acquired KU Energy, the parent company of Kentucky Utilities and Old Dominion Power. The transaction brought the principal Kentucky electric and gas utility businesses under a common corporate structure while retaining their established operating identities. Ownership changed several times during the following decade. In 2000, Powergen, a British energy company, acquired LG&E Energy. In 2002, Powergen was acquired by E.ON, a German-based energy company. In 2003, E.ON moved the LG&E Energy group into its American subsidiary, E.ON US Holdings. During this period, the underlying utility companies continued to operate under their respective names, while the corporate ownership structure reflected the consolidation of major international energy businesses. A further change occurred in 2010. PPL Corporation and E.ON announced an agreement under which PPL would acquire E.ON US, including the utility operations associated with LG&E and KU. The transaction was completed on November 1, 2010, and the E.ON US business became LG&E and KU Energy under PPL ownership. LG&E and KU Energy is therefore primarily a corporate and operating platform rather than a consumer-facing product brand. Its business scope centers on regulated utility operations, including the provision of electricity and natural gas through its operating companies. LG&E and KU are the principal utility names associated with the group, while Old Dominion Power extends the portfolio into Virginia. The company’s brand identity is closely connected to the local heritage and service territories of these utilities rather than to a single nationwide retail proposition.
History
LG&E and KU Energy was created in 1998 when LG&E Energy, the parent of Louisville Gas & Electric, acquired KU Energy. KU Energy controlled Kentucky Utilities and Old Dominion Power, giving the resulting organization a combined portfolio of utility businesses serving Kentucky and Virginia. Although the parent structure changed, the operating utilities continued to use their established local names. In 2000, Powergen acquired LG&E Energy. Powergen was a British-based energy company that expanded its presence in the United States through the transaction. In 2002, German energy company E.ON acquired Powergen, thereby gaining control of the LG&E Energy organization. In 2003, E.ON transferred the group to its American subsidiary, E.ON US Holdings. These changes placed the Kentucky and Virginia utility operations within a sequence of increasingly international corporate ownership structures. In 2010, PPL Corporation agreed to acquire E.ON US. PPL and E.ON announced the definitive agreement on April 28, 2010, with a stated transaction value of $7.625 billion. The transaction closed on November 1, 2010. After closing, E.ON US became LG&E and KU Energy, and the business became part of PPL’s utility portfolio. The resulting organization is composed of Louisville Gas & Electric, Kentucky Utilities, and Old Dominion Power. Louisville Gas & Electric and Kentucky Utilities are the principal Kentucky operating companies, while Old Dominion Power is a Kentucky Utilities subsidiary serving customers in Virginia. The group’s role is that of a regional utility holding company, coordinating and owning regulated energy businesses rather than marketing a single consumer product under the LG&E and KU Energy name.
