The world's largest electric utility companies
Utility companies sell electricity through a regulated market by operating generation, transmission and distribution facilities. In most countries, utilities provide energy, and are essential for many industrial and commercial enterprises, as well as households and other facilities such as recreational facilities. In light of likely increased demand for electricity, the aging grid infrastructure in many markets has been subject to recent concerns. This issue is forcing utilities to install new infrastructure and develop new technologies to provide customers with more reliable and improved access to energy. As the integration of renewable energy sources and investments in smart grid technologies are projected to raise a challenge, the basic utility’s business model is expected to undergo a major change.
Two of France’s electric utilities, EDF and GDF Suez, were considered the world’s largest utilities based on 2015 market values. EDF is a mostly government-owned company. Its primary focus is nuclear energy, while GDF Suez focuses mostly on natural gas and renewables. Ten of the top 20 utilities are based in the United States, with Duke Energy being the largest U.S. electric utility. Duke Energy is located in North Carolina and provides energy to over seven million customers. Almost all of its electricity generation comes from coal, natural gas, and oil.
