Power marketers are increasing their share of U.S. retail electricity sales

Competitive power marketers supplied about 21% of the retail electricity sold in the United States in 2016, up from 11% in 2005. The share of retail electricity sales of regulated investor-owned utilities fell from 62% in 2005 to 52% in 2016. This shift was driven by the Energy Policy Act of 2005, which repealed the Public Utility Holding Company Act of 1935 and closed the original federal regulatory structure established by New Deal-era legislation, which was a combination of public financial reforms and regulations in the 1930s
