Electric Distribution System
Installing advanced switches, sensors, and communication equipment are expected to improve reliability (e.g., shorten the duration of outages), enhance system efficiencies, and reduce operations and maintenance costs. This chart shows the number of automated feeder switches installed as part of the Smart Grid Investment Grant (SGIG) program, and conveys the approximate extent of coverage in the United States resulting from SGIG funding.
The table below includes SGIG program distribution system expenditures.

* In some circumstances, costs are incurred before devices are installed resulting in a reported cost where the quantity is zero.
* All dollar figures are the total cost, which is the sum of the federal investment and cost share of the recipient (the recipient cost share must be at least 50% of the total overall project cost).
** Projects only report data on devices they plan to install. Each project installs equipment that best supports their individual goals. Therefore, the number of projects reporting is expected to vary by equipment category. The individual project reporting pages show what equipment that project is installing.
