Construction began in the spring of 1970. The plant is divided into the 151 m long engine house and the three separate 98 m high boiler houses. On each boiler house stands an insulated steel chimney with a mouth height of almost 160 m. The heavy fuel oil delivered exclusively in tankers is liquefied by heating the ship's bunkers and pumped into the 60,000 m3 oil reservoirs. Another tank with 15,000 m3 content is filled with particularly low-sulfur oil, which is to be used in low-exchange weather conditions. The Heizkraftwerk Lichterfelde is of the utmost importance for supplying West Berlin with electrical energy, because here, too, electricity consumption - as in Germany - has more than doubled in ten years.
