Installation of advanced switches, sensors, and communication equipment is 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.

* In some circumstances, costs were incurred before devices were installed resulting in a reported cost where the quantity is zero.
Projects only reported data on devices they planned to install. Each project installed equipment that best supported 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 installed.
** 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).
*** In some cases the number of entities reporting was greater than the total number of projects funded by the Recovery Act because some projects had multiple sub-projects that reported data. View list of sub-projects.
