PPL packs a powerful punch in Kentucky, Pennsylvania, Tennessee, Virginia, and the UK. It distributes electricity to 10 million customers through regulated subsidiaries PPL Electric Utilities, two utilities in Kentucky, and Western Power Distribution Holdings in the UK. The company has more than 19,000 MW of generating capacity. Western Power Distribution operates four of the 15 distribution networks providing electricity service in the UK, though WPD (South West) and WPD (South Wales). In 2015 PPL sold its competitive energy operations in order to focus on its regulated utility businesses.
