No More DC Power in NYC

New York City has had direct current electrical service since 1882, but that ended today with the disconnecting of 10 E. 40th Street, the last DC customer in the city. Plenty of systems still use DC, most notably the subway, but ConEd has gradually moved the responsibility for AC/DC conversion to the customers, allowing ConEd to stop delivering DC power off the grid.
