The U.S. Energy Dept. has awarded $3.4 billion for “smart-grid investment grants” to modernize the electric power network and boost its efficiency and reliability. The 100 federal grants, funded by the American Recovery and Reinvestment Act, will be supplemented by more than $4.7 billion from the private sector, DOE says.

Among the six smart-grid grant categories, integrated and crosscutting systems will receive $2.15 billion and advanced metering infrastructure projects $818 million.
