US Recovery Act Smart Grid Regional Demonstration Projects
In November, 2009 the US Department of Energy announced 16 Regional Demonstration Project awards for a total of $185 million which will help fund utility-scale energy storage projects that will enhance the reliability and efficiency of the grid, while reducing the need for new electricity plants. Improved energy storage technologies will allow for expanded integration of renewable energy resources like wind and photovoltaic systems and will improve frequency regulation and peak energy management. The selected projects include advanced battery systems (including flow batteries), flywheels, and compressed air energy systems.[1]
