The project involved the development of a lignite based thermal power plant with an installed capacity of 2 x 125 MW. The plant was planned on a large greenfield site with dedicated areas for main plant facilities, ash handling and future expansion. The total plant area covered 85 hectares, supported by an ash dyke spread across 55 hectares for ash water recovery.

The project was designed to utilise locally available lignite sourced from captive mines located 9 km from the power plant. Lignite was transported directly to the plant through a conveyor system, ensuring continuous fuel supply and operational efficiency. Limestone was used for in furnace sulphur control to limit emissions.

Water requirements were met through a raw water pond with a storage capacity of 80,000 cubic metres, fed through an underground pipeline network of 12.5 km length from upstream tributaries. The power plant adopted circulating fluidised bed combustion technology, enabling efficient firing of low calorific value lignite while maintaining emission norms.

Each unit was designed for an annual energy generation of 1861 million units at 85 percent PLF. Power was evacuated through a 220 kV switchyard connected to the state transmission network.

TCE’s Scope

TCE provided end to end consultancy services covering basic and detailed engineering, project management, procurement support, construction supervision and commissioning assistance. The scope included preparation of technical specifications, tender evaluation, inspection and expediting at vendor works and site level coordination across multiple contractors.

Impact

TCE played a key role in integrating advanced combustion technology suitable for lignite fuel, optimising plant layout and ensuring seamless coordination between fuel handling, boiler systems, turbine generator systems and power evacuation infrastructure. The project was successfully commissioned with stable operations, achieving designed generation capacity and supporting reliable base load power supply to the regional grid.
