[1] It is owned and operated by Uttar Pradesh Rajya Vidyut Utpadan Nigam Limited (UPRVUNL), a state-owned utility responsible for thermal power generation in the region. [1] The station has an operating capacity of 2,320 MW, comprising five units of 200 MW each (Units 9-13, totaling 1,000 MW) and two supercritical units of 660 MW each (Units 14-15, totaling 1,320 MW). [1] Established in 1967 with initial smaller units that have since been retired, it marked a significant milestone in India's power sector as Units 9-13, commissioned between 1978 and 1982, introduced the country's first 200 MW coal-fired units. [1] [2] As one of Uttar Pradesh's oldest and largest thermal power facilities, Obra plays a critical role in meeting the state's electricity demand, contributing to UPRVUNL's total installed History Early Development The Obra Thermal Power Station was established in the 1960s by the Uttar Pradesh State Electricity Board (UPSEB) as one of India's pioneering large-scale coal-fired thermal power plants, aimed at addressing the growing electricity demands in the northern region. [7] Construction commenced in 1967 with technical assistance from Soviet engineers, marking an early instance of international collaboration in India's power sector development. [8] This initiative positioned Obra as a foundational asset for UPSEB's expansion of thermal generation capacity during a period when the country was rapidly industrializing and relying on imported technology for heavy engineering projects. [9] The initial phase of commissioning focused on smaller units to quickly build operational capacity. Two 50 MW units (Units 1 and 2) were brought online in 1967 and 1968, respectively, followed by three additional 50 MW units (Units 3, 4, and 5) in 1968, 1969, and 1971. [1] These units, totaling 250 MW, utilized conventional steam turbine technology and were integral to early power supply for Uttar Pradesh's grid. Subsequently, three larger units of 100 MW each (Units 6, 7, and 8, later derated to 94 MW due to operational factors) were commissioned between 1973 and 1976, enhancing reliability and output. [1] By the mid-1970s, these additions had solidified Obra's role in stabilizing regional power distribution. A key milestone occurred in 1977 with the commissioning of Unit 11, India's first 200 MW thermal unit, sourced from Bharat Heavy Electricals Limited (BHEL) and representing a shift toward higher-efficiency, domestically manufactured equipment. [2] [10] This unit, designed with reheat technology, set a precedent for future large-scale plants in India and contributed to the station's growing prominence. By the late 1970s, the cumulative capacity from these foundational units reached approximately 774 MW, establishing Obra as a cornerstone of UPSEB's thermal portfolio. [1] However, early operations faced challenges, including a major fire in November 1983 that severely damaged several units, including coal handling systems and turbines, resulting in temporary shutdowns and extensive repairs.
