The project involved the development of a coal based captive thermal power plant with an installed capacity of 25 MW. The scope covered execution at 2 separate industrial locations, with both units planned and executed in parallel. Each installation consisted of 1 x 25 MW generating unit supported by dedicated steam generators and balance of plant systems.

Each unit was equipped with 2 steam generators, each rated at 60 percent of turbine generator maximum continuous rating. Electrostatic precipitators with 4 fields were provided for each boiler. A reinforced concrete stack of 85 m height served the steam generators. Water requirements were met through mine pit based water sources. Power generated was evacuated through an existing 132 kV switchyard.

Coal handling systems included reclaim hoppers, screens and crushers to ensure controlled fuel sizing. Fly ash and bed ash were handled through dedicated collection, storage and transport systems integrated with existing industrial infrastructure. The plant was designed for automated operation with centralised control of power generation, coal handling and ash handling systems.
