It was lit by Joseph Swan's incandescent lamp on 3 February 1879. Thomas Edison began serious research into developing a practical incandescent lamp in 1878. Edison filed his first patent application for "Improvement In Electric Lights" on 14 October 1878. After many experiments, first with carbon in the early 1880s and then with platinum and other metals, in the end Edison returned to a carbon filament.

Edison Electric Institute such as the electric grid were included in the National Cyber Strategy. After Hurricane Maria hit the island of Puerto Rico in 2017, the federal government invested $3.2 billion into restoring the island's power grid. The Edison Electric Institute deployed Carlos D. Torres, a retired vice president at Consolidated Edison, to Puerto Rico to coordinate storm rebuilding of the power grid. Subsequently, Torres was appointed by Gov. Ricardo Rossello as coordinator for storm restoration. EEI supports the use of drones (unmanned aircraft systems, or UAS) by electric power companies to maintain electric grids and restore downed service. In July 2016,
