The US Department of Energy is awarding $620 million for projects around the country to demonstrate advanced Smart Grid technologies and integrated systems. These 32 demonstration projects, which include large-scale energy storage, smart meters, distribution and transmission system monitoring devices, plug-in vehicles, and a range of other smart technologies, will act as models for deploying integrated Smart Grid systems on a broader scale.
The funding awards are divided into two topic areas. In the first group, 16 awards totaling $435 million will support fully integrated, regional Smart Grid demonstrations in 21 states, representing more than 50 utilities and electricity organizations with a combined customer base of almost 100 million consumers.
These projects include streamlined communication technologies that will allow different parts of the grid to communicate with each other in real time; sensing and control devices that help grid operators monitor and control the flow of electricity to avoid disruptions and outages; smart meters and in-home systems that empower consumers to reduce their energy use and save money; energy storage options, including the use of plug-in vehicles and residential batteries; and on-site and renewable energy sources that can be integrated onto the electrical grid.
In the second group, an additional 16 awards for a total of $185 million 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.
