Borj-e Milad, the “Tower of Birth” rises 435 meters into the sky above Tehran. It is the Iran's highest tower and the sixth-highest TV tower in the world. Even from afar, Borj-e Milad, standing on a small elevation in the city's Gischa district, is an amazing sight to behold. Built on an octagonal plinth, its shape bridges the modern and traditional Iranian architectural styles. Even in the lower portion spanning six floors, the huge tower offers visitors 63 shops, 11 snack bars, a cafeteria and an exhibition area. Then you take the elevator to the top. At 250 meters elevation, you come to the world's largest tower head. With 12,000 square meters spread over 12 floors, there is plenty of space for several viewing platforms, an art gallery, a museum featuring Iranian celebrities and a 400-seat revolving restaurant. Above the tower head is a four-stage aerial mast, itself 120 meters high. The bottom stage of the mast is used for transmitting telephone calls, with the three upper levels transmitting on the frequency used by the state-owned radio and television broadcaster.

electrical power, heat and colling for the Milad Tower.

Helping make all this possible is a 20-cylinder genset from MTU Onsite Energy which has been supplying electrical power, heat and cooling since the end of last year. The natural-gas-powered combined cooling, heat and power system with its Series 4000 MTU engine delivers 1,948 kW of electrical power with 70% efficiency. Operated as a standalone system, it first covers the tower's own power, heating and cooling requirements. When more power is produced than is needed by the tower, it is simply fed into the public grid. During realization of the project, MTU partner Tanir ESCO was responsible for complete engineering and assembly on site and also carried out commissioning. It is now handling maintenance and other services. Iran is increasingly turning to natural gas as a source of energy with a view to reducing CO2 emissions and other pollutants such as sulfur and nitric oxides.
