Hydropower Regulation: A Bipartisan Success Story
On August 9, 2013, President Obama signed into law the “Hydropower Regulatory Efficiency Act of 2013” (the “Act”). This legislation, passed with overwhelming support in the House and Senate, streamlines the regulatory approval process for certain hydroelectric power (“hydropower”) projects. Perhaps more importantly, the Act reflects bipartisan recognition of the benefits of hydropower. According to […]
