Public Utility Holding Company Act (PUHCA)
US federal act of 1935 that grants the Securities and Exchange Commission, a US financial regulator, the power to prevent electric public utility holding companies from having generation assets in two areas of the US that are not geographically adjoining.
In August 2005, the Energy Policy Act of 2005 repealed PUHCA, effective in February 2006. It was replaced by a much weaker set of laws called the Public Utility Holding Company Act of 2005.
