GES-1, known as State Electric Station No. 1, is the oldest operating thermal power plant in Russia and is located on Rausha Embankment in Moscow.

Originally called MGES-1 or Rausha Power Station, it was built by the joint-stock company "Society of Electric Lighting 1886" on the orders of Emperor Alexander III and became the first station to produce alternating current. Construction began in 1896, and on November 28, 1897, the first phase with a capacity of 3.3 MW was launched. At that time, there was only one power station in Moscow, the central direct current station "Georgievskaya," with a capacity of 1.5 MW, built in 1888 on Bolshaya Dmitrovka Street (the building now houses the Moscow State Exhibition Hall New Manege). Seven years after it began operation, the capacity of GES-1 increased to 10.5 MW. The station was equipped with oil-burning boilers from "Siemens and Linz," as well as steam piston engines and generators from "Siemens and Halske" with a capacity of 450 kW.

In 1899-1900, MGES-1 supplied electricity to the lines of the first Moscow trams.

On December 29, 1917, by decree of the Council of People's Commissars, all property of the Society was nationalized and declared the property of the RSFSR. Over time, the facades of the building also changed.
