Top utility companies in US

Published 20 August 2017

The US electric utility industry has seen some of the biggest mergers in recent years, with Duke Energy and Exelon emerging as the major players in the space. In June 2012, Duke Energy merged with Progress Energy, growing its customer base significantly. In the same year, Exelon merged with Constellation Energy, strengthening its presence in the power distribution in the US.

According to a report by the US Energy Information Administration (EIA), the annual growth rate of electricity sales has hovered around 1% or less in the country over the past five years. Compared to economic growth rate in the US in recent years, the demand for electricity has remained consistently lower. 

In the US, coal consumption in the power generation sector has shown a gradual decline in the past few years, as companies increasingly use natural gas and renewable sources as wind and solar. Also, falling capital costs of renewable energy sources have contributed to a drop in the usage of coal as the fuel for power generation.

Here is the list of top utility companies in the US:

Duke Energy: Headquartered in Charlotte, North Carolina, Duke Energy is one of the electric power holding companies in the US. The company was started in 1900 as the Catawba Power Company.

Its fleet of power plants has a generating capacity of about 50,200MW. In April 2017, it announced plans to invest to $13bn to modernise the North Carolina’s electric system in the US.
