President Barack Obama announced the largest single energy grid modernization investment in U.S. history, funding a broad range of technologies that will spur the nation's transition to a smarter, stronger, more efficient and reliable electric system. The end result will promote energy-saving choices for consumers, increase efficiency, and foster the growth of renewable energy sources like wind and solar. The $3.4 billion in Smart Grid Investment Grant awards are part of the American Reinvestment and Recovery Act, and will be matched by industry funding for a total public-private investment worth over $8 billion. Applicants state that the projects will create tens of thousands of jobs, and consumers in 49 states will benefit from these investments in a stronger, more reliable grid. An analysis by the Electric Power Research Institute estimates that the implementation of smart grid technologies could reduce electricity use by more than 4 percent by 2030. That would mean a savings of $20.4 billion for businesses and consumers around the country. The grants include $1 billion create the infrastructure and expand access to smart meters and customer systems so that consumers will be able to access dynamic pricing information and have the ability to save money by programming smart appliances and equipment to run when rates are lowest. Two billion dollars will be invested in "smart" components such as smart meters, smart thermostats and appliances, syncrophasors, automated substations, plug in hybrid electric vehicles, renewable energy sources, etc.
The benefits could reach to the broadband sector as well, said Craig Settles, a broadband analyst and president of consulting firm Successful.com. The backbone of the smart grid, which uses digital technology to deliver electricity and control use, will be an Internet Protocol-based network, and the result could mean new broadband deployment in some areas. "The interdependencies and mutual influences of smart grid and broadband technologies should enable both grant programs to have a greater payback for their respective awardees," Settles said in an e-mail. "All of the things people are talking about doing with smart grid, such as moving "green" energy from windmill farms and proactively managing energy usage, require at some point a fast data connection. That means fiber (the ideal) or possibly super-fast fixed wireless."
The smart grid will include a smart-meter monitoring device paired with electricity meters at buildings. That device will collect data on energy use, as well as control many of the electrical appliances in the building, Settles said. Those devices will need to connect back to the electric utility through an IP network. With that in mind, smart grid and broadband applicants can work together, or piggyback on each other's networks, Settles said.
"A community's fiber network can provide the backhaul for this [smart-grid] data," he said. "Or a utility can build its own fiber backhaul and determine how to make that fiber available for local government and other institutions for their use. It's cheaper to expand than to build from scratch."
