Smart grid in the United States (FOA) that will lay the groundwork for providing nearly $4 billion in American Reinvestment and Recovery Act funds to support smart grid projects. The Notice of Intent was issued for DOE's Smart Grid Investment Grant Program, which will provide grants of $500,000 to $20 million for smart grid technology deployments and grants of $100,000 to $5 million for the deployment of grid monitoring devices. The program will provide matching grants of up to 50% of the project cost, and the total funding for the program is $3.375 billion. In addition, the draft FOA paves the way toward an offer of
