Overview
Power Machines, also known as Silovye Mashiny or Silmash, is a Russian energy-equipment and heavy engineering company headquartered in Saint Petersburg. Established in 2000, it brought together the industrial, engineering and intellectual resources of several long-established Russian power-machinery enterprises. The group’s historical industrial base includes the Leningrad Metal Works, founded in 1857; Electrosila, founded in 1898; the Kaluga Turbine Works; the Turbine Blades’ Plant; the Reostat Plant; and Energomachexport. The wider structure has also included engineering and research capabilities associated with the N. I. Polzunov Central Boiler and Turbine Institute. The company’s principal business is the design, manufacture, supply and servicing of equipment for electric-power generation. Its portfolio includes steam turbines, gas turbines, turbine generators and equipment for thermal, nuclear and hydroelectric power stations. Power Machines has manufactured steam turbines with capacity of up to approximately 1,200 MWe and has supplied turbine-generator equipment for major Russian nuclear projects, including the Leningrad Nuclear Power Plant II and the Novovoronezh Nuclear Power Plant II. Its products and engineering services are aimed primarily at utilities, power-plant developers and industrial energy customers rather than consumer markets. Power Machines developed its international business through equipment exports, technology cooperation and project contracts. Reference material identifies deliveries to 57 countries outside Russia and describes Asia as a significant overseas market. The company has also worked with foreign technology partners. Siemens held a minority stake before selling it to Highstat in 2011, and Power Machines participated in the production or development of gas-turbine equipment based partly on licensed Siemens technology. Its international activities later became constrained by sanctions and geopolitical restrictions. Ownership and corporate status changed materially during the 2000s and early 2010s. At the end of 2009, Highstat Limited controlled by Alexey Mordashov held 69.92 percent of the shares, Siemens held 25 percent and minority shareholders held the balance. In December 2011, Highstat acquired Siemens’ interest for less than US$280 million, after which Power Machines was delisted from the MICEX-RTS exchange. A subsequent mandatory offer to minority shareholders prompted criticism from the Investor Protection Association, and the Federal Financial Markets Service fined Highstat 250,000 rubles. Those historical figures are not treated as current financial information. The company faced further strategic and commercial pressure after United States sanctions were imposed in 2018 over alleged support for Russia’s attempted annexation of Crimea. The measures were associated with the loss of a reported power-equipment contract in Vietnam, difficulties receiving payment for work completed for Ukraine’s DTEK, and the disposal of Power Machines’ stake in Siemens Gas Turbine Technologies. Despite these constraints, the company continued developing domestic production capabilities. In 2020 it received a contract connected with the 1.4-gigawatt Sirik power plant in Iran. In 2022 it assembled and tested a domestically produced high-power gas turbine, an effort intended to reduce dependence on imported equipment that had become unavailable because of sanctions and technology restrictions. Power Machines is therefore positioned as a strategic Russian industrial manufacturer focused on power-generation infrastructure, localization of energy technology and large-scale equipment projects. Its historical strengths are turbine engineering, generator manufacturing, project integration and servicing. Its present international reach, ownership structure, financial condition and executive roster require verification from current corporate or regulatory sources.
History
Power Machines was formed in 2000 as a Russian power-equipment group combining several established enterprises with deep experience in turbine, generator, blade, electrical-equipment and energy-project manufacturing. The consolidation created a broader industrial platform rather than a consumer-facing brand. Its constituent businesses included the Leningrad Metal Works, established in 1857; Electrosila, established in 1898; the Kaluga Turbine Works; the Turbine Blades’ Plant; the Reostat Plant; and Energomachexport. Research and engineering capabilities associated with the N. I. Polzunov Central Boiler and Turbine Institute were also part of the wider structure described in company references. The resulting group focused on large power-generation systems. Its capabilities covered steam turbines, gas turbines, turbine generators and equipment for thermal, nuclear and hydroelectric stations. Power Machines supplied equipment for major Russian nuclear projects, including the Leningrad Nuclear Power Plant II and Novovoronezh Nuclear Power Plant II. The company also developed an export business, with reference material stating that it supplied equipment to 57 countries outside Russia and that Asia was an important market. During the 2000s, Power Machines had a mixed shareholder base. Information for 31 December 2009 attributed 69.92 percent of the shares to Highstat Limited, controlled by Alexey Mordashov, 25 percent to Siemens and 5.08 percent to minority shareholders. Siemens' involvement reflected a period of international industrial cooperation. In December 2011, Highstat acquired Siemens' stake for less than US$280 million, after which the company was delisted from the MICEX-RTS exchange. In August 2012, Highstat made a mandatory offer for the remaining shares. The Investor Protection Association argued that the offer materially undervalued the minority holdings, and the Federal Financial Markets Service imposed a 250,000-ruble fine on Highstat following a complaint. Management and legal scrutiny continued to attract attention. In 2017, chief executive Roman Filippov was reportedly placed under temporary arrest on suspicion of divulging state secrets. The event is part of the company's documented public record, although the available reference material does not establish the final legal outcome. Power Machines' international activities were significantly affected by sanctions imposed by the United States in 2018. The U.S. action cited alleged support for Russia's attempted annexation of Crimea. The consequences described in reference material included the loss of a reported US$500 million contract in Vietnam, an inability to receive payment for a completed contract involving Ukraine's DTEK, and the sale of Power Machines' 35 percent interest in Siemens Gas Turbine Technologies LLC. These events reduced the company's access to foreign technology, finance and overseas projects. The company continued to pursue international and domestic projects. In 2020 it was awarded a contract associated with construction of Iran's 1.4-gigawatt Sirik power plant. In 2022, Power Machines assembled and tested its first domestically made high-power gas turbine, presenting localization as a response to the loss of imported equipment and technology access after sanctions. The company consequently became increasingly associated with import substitution and the domestic development of strategic power-generation machinery. Power Machines' historical identity is that of a vertically integrated Russian industrial group rather than a narrowly defined product label. Its business combines legacy manufacturing plants, engineering institutes, turbine and generator production, project delivery and servicing. Current ownership, management, operating markets and financial performance are not fully established by the supplied reference material and should be checked against current Russian corporate records and regulatory disclosures.
