17 Jan 1930.   USS Lexington (CV-2)  completed a 30-day period in which she furnished electricity to the city of Tacoma, Wash., in an emergency arising from a failure of the city’s power supply. The electricity supplied by the carrier totalled 4,251,160 kilowatt-hours.  From Historylink.org:

In the 1920s, Tacoma received most of its electrical energy from dams on the Nisqually and Skokomish Rivers. Supplemental energy came from the Dock Street steam plant (1922). A drought in 1929 severely cut the power from the hydroelectric sources. The shortage became so critical that Superintendent Ira S. Davisson (1860-1951) had to cut power to Cascade Paper Company. Cascade laid off 300 employees. Fort Lewis turned the lights out in the barracks at 4:00 p.m.

The “Lady Lex” arrived at Tacoma’s Baker Dock in the rain to the sounds of a brass band and the applause of City Light customers. The Lexington’s boilers supplied a quarter of Tacoma’s power for about 30 days, leaving on January 17, 1930. That month, the skies opened and rain filled Tacoma’s reservoirs.

Tacoma enjoyed a special relationship with the carrier until its loss at the Battle of the Coral Sea on May 8, 1942. (ed: CO’s POSTEX report here – SJS)
