In 2009, the U.S. Department of Energy (DOE) launched the Smart Grid Investment Grant (SGIG) program, funded by $3.4 billion invested through the American Recovery and Reinvestment Act of 2009 (ARRA) to modernize the nation"s electricity system. Projects began in 2010, and the program was completed in 2015.

This final report summarizes the major SGIG achievements, key project results, and lessons learned across the smart grid landscape, which included:

  • Synchrophasor technologies on electric transmission systems.
  • Distribution automation (DA) technologies and systems, including advanced sensors and self-healing controls.
  • Advanced metering infrastructure (AMI), including smart meters and two-way communications networks.
  • Customer systems, including in-home displays (IHD), programmable communicating thermostats (PCT), and direct load control devices (DLC) that enable utilities to offer time-based rates and incentives.
