HOUSTON, Feb. 20, 2014 /PRNewswire/ -- Direct Energy, North America's largest competitive energy and energy-related services company, today announced gross revenue for the full year 2013 of US $11.4 billion (£7.3 billion), an increase of 28 percent, and an operating profit of US$436 million (£276 million). Direct Energy is the North American subsidiary of Centrica plc (LSE: CNA). Centrica reported full year 2013 revenues of US$41.6 billion (£26.6 billion) with an operating profit of US$4.2 billion (£2.7 billion).

The operating profit in 2013 includes US$21 million of integration costs and US$32 million of additional customer amortization related to the Hess Energy Marketing acquisition announced in July. Badar Khan, President and CEO of Direct Energy, said: "Direct Energy is poised for significant growth as we further integrate Hess Energy Marketing, continue accelerating residential customer growth via our digital platform from the Bounce Energy acquisition, and introduce innovative products and services across our energy and home services offerings. Despite competitive pressures and rising gas and power prices impacting our margins, we operated more efficiently, and grew our customer base to deliver significant, albeit slightly reduced, profit. We also saw impressive customer growth in most of our businesses." Direct Energy reorganized in late 2013 creating a Chief Operations Officer position focused on reducing costs through operational synergies. The company is also bringing creative products and services to market to drive customer growth. Additionally, Direct Energy recently completed the disposal of three Texas-based power stations, sold to Blackstone in December for US$687 million (£420 million). In 2014, cost competitiveness and customer innovation will be key priorities. The home services business will continue to see organic growth in its protection plan offering and will also begin a transition to a single operating system. A new residential energy billing platform will launch in Alberta, and new consolidated call centers in Phoenix and Tulsa already are generating efficiencies. Building on innovations, such as the 'Power to Go' prepaid and 'Free Power Saturdays' products, Direct Energy recently launched new mobile web-enabled smart thermostats in Texas and Canada, and expects to continue to expand our product and services offerings across energy and services. "We are taking bold steps to leverage efficiencies across our lines of business and through further integration of acquisitions, so that we can deliver customer-engaging innovations that add value, convenience and more options for our customers," said Khan.
