History

BHEL was established in 1956 ushering in the heavy electrical equipment industry in India. Heavy Electricals (India) Limited was merged with BHEL in 1974.[4] When it was set up in 1956, BHEL was envisaged as a plain manufacturing PSU, with technological help from the Soviet Union.[5] In 1980's it was cutting edge in thyristor technology.[6] In 1991, BHEL was converted into a public company. Over time, it developed the capability to produce a variety of electrical, electronic, and mechanical equipment for various sectors, including transmission, transportation, oil and gas, and other allied industries.[4] However, the bulk of the company's revenue is still derived from the sale of power generation equipment such as turbines and boilers. As of 2017, equipment supplied by BHEL constituted around 55% of the total installed power generation capacity in India.[7] The company also supplies electric locomotives to the Indian Railways and defence equipment such as the Super Rapid Gun Mount (SRGM) naval guns manufactured in partnership with the Ordnance Factory Board and simulators to the Indian Armed Forces.[4][8]

It also has been exporting its power and industry segment products and services for over 40 years. BHEL's global references are spread across over 76 countries across all the six continents of the world. The cumulative overseas installed capacity of BHEL manufactured power plants exceeds 9,000 MW across 21 countries including Malaysia, Oman, Iraq, UAE, Bhutan, Egypt, and New Zealand. Their physical exports range from turnkey projects to after sales services.[9]
