Leningradsky Metallichesky Zavod
The company was founded in 1857, in Saint Petersburg, Russia as a boiler works and small foundry. The industry is still located on the original site, on the right bank of the Neva River, in St. Petersburg. Steam turbines have been produced here since 1907 when the company was licensed to build French Rateau turbines. At the same time it began to build gun turrets, gun mountings and torpedo tubes. In 1912 the company received a contract for a number of Novik-class destroyers originally designed by AG Vulcan Stettin. It contracted at the same time with Vulcan to build a shipyard as well as for licenses for Curtis_AEG-Vulcan turbines and Vulcan-Yarrow boilers. In 1914 the company was renamed Petrograd Metal Works (Petrogradskiy Metallicheskiy Zavod) when Saint Petersburg was renamed as Petrograd. At the beginning of World War I the company had 4 building slips and employed 5,500 workers.
Water turbines for various Hydropower Stations, have been produced since 1924. Since 1957, the LMZ has also produced gas turbines. Since 2000, LMZ is a division of the Power Machines company, based in Russia.
International business 
About 700 turbines made by LMZ are now working at hundreds of electric power plants in more than 80 countries around the world. 2,300 power turbines were produced at the LMZ plant all together, with their total installed capacity of 300,000,000 KW. Most of the turbines are working at electric power stations in Russia, as well as in all other states of the former Soviet Union.
10% of the world's power turbines are now built at the Leningradsky Metallichesky Zavod (eng: Leningrad Metal Works). In the steam turbine market Siemens Energy has a installed steam turbine fleet with a capacity of 530 GW, GE as second still has an allover capacity of 445 GW. Followed by Alstom with 385 GW. All these figures are based on the status of 2005. LMZ with its allover capacity of 300 GW is on the fifth place.
