The nearest major Railhead is Gondia on Mumbai Howrah rail route at 30 km distance from Plant. The nearest seaport is at Mumbai at a distance of 985 km. The plant is located about 328.25 Meters above Mean Sea Level. The maximum ambient temperature at plant location is about 47°C and annual mean relative humidity is 58%.
Plant Detail
The Tiroda power plant employs Supercritical Technology, which is fuel efficient and environment friendly. It operates at pressure & temp of 254Kg/cm2 & 571 degrees centigrade. The Turbine Generator is a three-cylinder tandem compound, four exhausts, condensing reheat turbine, Static excitation & hydrogen cooled generator with 22KV stator voltage, Digital Electro-Hydraulic Control system (DEH) system designed & installed for high operating efficiencies, maximum reliability and smooth operation.
The plant is located on 454.86 hectares of land, which houses the major equipment such as boilers, turbines, generators, transformers, switchyards, cooling towers, coal handling plant, ash handling plant, circulating water pump house, track hopper, wagon tippler, reservoirs, Electrostatic Precipitator, water treatment plant, ash dikes etc. For uninterrupted coal supply, the plant incorporates Rail under Rail (RUR) on the busiest Mumbai- Howrah rail route.
Power Evacuation
The plant has long term power purchase agreements with Maharashtra State for its entire net capacity of 3085 MW. The power generated by the plant is evacuated through one dedicated 400kV double circuit 219km Tirora-Warora transmission line and two 765 kV Tiroda-Aurangabad 630km long transmission lines.
Achievements
The plant has achieved the highest level of operational excellence through business process transformation initiative setting highest benchmark in operational efficiency parameters. The highest standards of safety and housekeeping are being maintained at plant which has enabled APL Tiroda bag the following recognitions:
- Tiroda power plants were awarded with a “Five Star Rating” certificate from the British Safety Council, the highest recognition in the field.
- Tiroda plant secured a patent for the “Real Time Critical Bypass Alarm Alert System” from the Patent Office in November 2023.
- Tiroda plant received multiple awards from CEE for: Sustainable performance in private sector; Operational excellence for the best energy efficient unit in the private sector 500 MW category; and National energy efficient team of the year.
- Certified for ISO 9001:2015 Quality Management System, ISO 14001:2015 Environment Management System, ISO 45001:2018 Occupational Health & Safety Management System, ISO 50001:2018 Energy Management System, ISO 55001:2014 Asset Management System, ISO 46001-2019 Water Efficiency Management System, ISO 27031:2011 Guidelines for information and communications technology readiness for business continuity, and ISO 22301:2019 Business Continuity Management System.
- 5S Par Excellence Award at 8th National Conclave of NCQC in June 2022.
- Tiroda station was awarded 2nd position in Best Boiler Use-2022 organized by Directorate of steam boiler, Government of Maharashtra.
- Certified as Single Use Plastic Free by Confederation of Indian Industries (CII).
- Prashansa Patra in recognition of Developing & Implementing Effective Management System & Procedures and Achieving Good Performance in OHS.
- Commendation Certificate from the Institution of Engineers (India) Limited for adopting best safety practices.
Fuel
The fuel requirement of the plant is presently met through sourcing of domestic coal up to 11.3 MTPA under Fuel Supply Agreement with subsidiaries of Coal India Ltd. Balance requirement is met through Inter-Plant Transfer of coal from the Mundra power plant, coal available under E-auction from various subsidiaries of Coal India Ltd., and imports.
Water
The plant has water requirement of 70 million cubic meters per annum, which is sourced from the Wainganga River nearby. The makeup water pump house installed on river Wainganga draws water from the source. The plant has a reservoir with buffer capacity of 45 days of water intake to help it tide over water shortage periods in the summer. We have laid two pipes of 9 km length each along the route to ensure uninterrupted supply of water to four reservoirs of 16, 39, 33 and 23 hectares respectively at the plant location. The water from Wainganga caters to the water requirement to the plant mainly for condenser cooling, various plant process and for domestic use. Induced draft cooling towers are installed to cool the circulating water for reuse. Entire plant is designed on zero discharge philosophy.
Ash Management
The Tiroda plant has undertaken numerous initiatives towards Fly Ash utilisation generated during the power generation process. Despite major challenges such as non-availability of Limestone nearby which restricts cement manufacturing for fly ash utilisation, it has achieved high level of fly ash utilisation through supply of fly ash to cement plants in the region and other initiatives such as establishment of fly ash brick plant, educating and encouraging local farmers to utilise fly ash in agriculture etc. We have installed HCSD (high concentration slurry disposal) system for 100% dry ash utilisation.
The plant is equipped with latest pollution control equipment such as high efficiency electrostatic precipitators- the largest in Asia, Dust extraction & Suppression system, 275m high chimney, to limit the SPM, SOx, NOx emissions.
