Plant Details
Adani - Dahanu Thermal Power Station has implemented integrated management systems (IMS) in its processes and is certified for quality management, environment management, occupational health and safety assessment studies, social accountability management, information security management, energy management and accreditation for ADTPS coal & Ash testing laboratory. The plants utilise a mix of Indian coal and imported coal as fuel.
Design and development
Complete automatic control & monitoring of the three cylinders reheat condensing turbine, boiler and auxiliaries by Digital Distributed Control, Monitoring, and Information System (DDC-MIS) to maintain trouble free output. Highly advanced Supervisory Control and Data Acquisition (SCADA) system for complete centralized control over transmission and distribution. The CW Systems are equipped with concrete volute pumps to facilitate the smooth functioning of Sea water based once through condenser cooling water system. An Electronic Electrostatic Precipitator (ESP) of 99.9% efficiency to collect fly ash with In-house developed Ammonia dosing system to improve collection efficiency. Flue Gas Desulfurization (FGD) Unit I and II commissioned in October 2007.
Power evacuation and Power purchase agreements
Power Purchase Agreement
ADTPS supplies power under a long-term Power Purchase Agreement (PPA) to the Mumbai power distribution circle of Adani Electricity Mumbai Limited (AEML).
Power Evacuation
ADTPS is directly connected with receiving stations at Mumbai through AEML owned transmission lines. It is also directly connected with the Main grid. At full capacity, the ADTPS can produce 12 MU per day.
Benchmarks, Achievements
Benchmarks:
ADTPS has received Copyright for three innovative works from Copyright Office of Government of India, New Delhi.
- Reduction in Overhauling Time - Implementation of Work procedure has ensured considerable reduction in overhauling period to 15 days. Thereby saving Generation revenue equivalent to at least 10 to 15 days.
- Energy Deviation Report - An effective tool for energy consumption monitoring and optimization. This helps operation personnel to utilize energy efficient equipment to cater economical generation.
- Improvement of Coal Mill Performance by Auto Operation - Software developed by ADTPS team by studying the correlation between air and coal flow. This logic has helped to avoid undue variation in load and other process parameters even during very heavy rain.

Fuel
ADTPS requires, on a full load basis, approximately 2.5 million tons of coal per annum. The plants utilise a mix of Indian coal and imported coal as fuel. The indigenous fuel is received from SECL (Korba) and imported from Indonesia. ADTPS has made remarkable achievements on parameters of Auxiliary power consumption (APC), Specific Oil Consumption & DM water consumption by consistently maintaining them lower than the national average for a generation unit of this size.
Water
The Irrigation Department, Government of Maharashtra supplies fresh water from the Surya Prakalpa Reservoir to the ADTPS. In addition, ADTPS also uses sea water for condenser cooling.
