What is PUHCA?

The Public Utility Holding Company Act (PUHCA) of 1935 prevents utility holding companies from using profits from regulated activities to subsidize unregulated businesses. The Union of Concerned Scientists warns that repealing PUHCA could lead to market consolidation, increased rates, and the suppression of renewable energy in favor of fossil fuels.

• The Public Utility Holding Company Act (PUHCA) of 1935 serves as the sole legal mechanism preventing utility holding companies from using profits derived from regulated business activities and captive customers to subsidize unregulated business ventures, requiring a strict separation between the two.
• PUHCA was created to address abuses from the 1920s and 30s, specifically complex pyramid structures where a small number of investors controlled numerous subsidiaries. This structure allowed for inflated service charges between subsidiaries to be hidden in regulated rates and shielded holding companies from debt liability, which some analysts link to the 1929 Stock Market Crash and the Great Depression.
• Repealing PUHCA without new protections could lead to the creation of multinational corporations that evade state and federal regulation, the use of regulated profits to eliminate small business competitors, and a wave of mergers. One Wall Street analyst predicted that 80 percent of electric utilities could disappear within 10 years.
• The repeal of PUHCA could increase U.S. reliance on fossil fuels because large companies with significant market power may suppress energy efficiency and renewable energy. This is significant as fossil fuel plants are responsible for approximately one-third of global warming gases, two-thirds of acid rain emissions, and over 25 percent of urban smog precursors.
