BHEL enhances output of Obra Thermal Power Station to 216 MW

Bharat Heavy Electricals (BHEL) has achieved a major landmark in its after-market services business by successfully renovating, modernizing and up-rating a 200 MW thermal set at Obra Thermal Power Station in Uttar Pradesh. Following the renovating and modernization (R&M) of the unit by BHEL, the rated output of the machine has been enhanced to 216 MW and the unit has been synchronized with the grid. After successfully being in operation for its life span of 25 years, the working life of the machine has been further extended by another 15-20 years. R&M of Obra was initiated with the original technology provider but was subsequently executed successfully by BHEL’s own in-house engineering capabilities.

BHEL succeeded in loading the machine to 218 MW i.e 2 MW higher than design capacity with all parameters within the acceptable range. Significantly, this is also the first instance of a successful modernization and up-rating of any 200 MW class machine in India and the technical capability demonstrated by BHEL is a very significant credential for future R&M business in India.

BHEL has already executed R&M/ up-rating of sets up to 120 MW rating with completion of R&M of 4 sets of 120 MW and up-rating of 6 sets of 110 MW units. With the R&M and up-rating of Obra unit 9, BHEL has successfully entered into 200/ 210 MW segment. Presently, R&M of 5 sets of 110 MW units are at different stages of execution by BHEL besides the remaining 4 sets of 200 MW Unit at Obra.
