Mitsubishi Electric Ships Milestone 2,000th Turbine Generator

TOKYO--(BUSINESS WIRE)-- Mitsubishi Electric Corporation (TOKYO:6503) announced today that it has shipped its milestone 2,000th turbine generator, a 682,000 kVA unit, to a thermal power plant owned by Dominion Virginia Power, a subsidiary of Dominion Resources, Inc., in Warren County, Virginia in the United States.

Mitsubishi Electric, the leading company in the Japanese generator market, has continuously expanded its global market since it started manufacturing turbine generators in 1908. The company completed a large expansion of its generator factory in Kobe in March 2012, increasing production capacity in order to be equivalent to the growth of world-wide electric power demand. Owing to the expansion, the factory has also become capable of producing world's largest-class (2,000MVA) generators.

Milestones in Mitsubishi Electric's generator production

  • 1908 – Mitsubishi Shipyard (Nagasaki, Japan), made first turbine generator.
  • 1921 – Mitsubishi Electric Corporation was founded.
  • 1923 – Mitsubishi Electric began production of turbine generators in Nagasaki.
  • 1963 – Mitsubishi Electric began production of turbine generators in Kobe.
  • 1976 – Made Japan's largest capacity (1,300,000 kVA) generator.
  • 1981 – Cumulative production of generators reached 1,000 units.
  • 1996 – Made world's largest-class (286,000 kVA) air-cooled generator.
  • 2000 – Made world's largest-class (1,600,000 kVA) generator.
  • 2004 – Developed and began production of highly-efficient indirect hydrogen-cooled generators for gas turbine combined cycle*.
  • Mar. 2012 – Completed factory expansion in Kobe, increasing production capacity by approximately 30% per annum.
  • Oct. 2012 – Has shipped its milestone 2,000th turbine generator.

* Gas turbine combined cycle (GTCC) power stations use gas and steam turbines in combination to generate electricity in two stages, utilizing high-temperature exhaust gas from the gas turbine to produce the steam to drive the steam turbine. This configuration enables GTCC power plants to achieve a higher thermal efficiency, which in turn reduces fuel consumption and lower emissions.
