Udupi, Karnataka
Capacity: 1200 MW Type: Coal Based
The Udupi power plant is a 2 X 600 MW imported coal-based power project in the Udupi District of Karnataka. It was acquired by Adani Power Limited from the Lanco Group in the year 2015.
Located on the west coast of India, the plant is situated in the village of Yellur, between Mangalore and Udupi.
The Udupi plant is the first independent power project (IPP) using 100% imported coal as fuel in the country. It was awarded the Gold Shield award for early completion of Thermal power project Unit-1 from Ministry of Power, Government of India in FY 2010-11, and the prestigious Golden Peacock Environment Management Award in FY 2014-15.
The Udupi Power Project has an operational long-term power purchase agreement with Karnataka State DISCOMs for 1080 MW of its capacity.
Location
The Udupi Power Plant is located in the Udupi District (erstwhile Dakshina Kannada District) of Karnataka, comprising villages of Yelluru, Tenka, Santhuru and Bada and is about 35 km north of Mangalore City in Karnataka State, India. It is flanked by Konkan Railway on the west, local roads to Mudarangadi village on the east and north and Padubidri-Karkala state highway on the south. The area where the power plant is located has been declared as an industrial area under Section 3 (1) of the Karnataka Industrial Area Development Board (KIADB) in the Gazette of the Government of Karnataka.
The site is about 28m above mean sea level and falls under seismic zone III. The maximum ambient temperature is about 38°C and the annual mean relative humidity is 74-80%. The nearest seaport is at Mangalore (New Mangalore Port).
Plant Details
Each unit of 600 MW capacities has one sub critical coal fired steam generator connected to a reheat type condensing steam turbine and generator with sea water cooled condenser and all other required auxiliaries.
Each steam turbine is of 3000 rpm, tandem compound, single re-heat, condensing type machine with extractions for regenerative feed water heating. The turbine is designed for mainstream pressure of 170 kg/cm2 (a) and inlet temperature of 537°C.
The plant has a 275-Meter-High Chimney, High Efficiency ESPs, low NOx burners, etc. to limit the SPM, SOx, NOx emissions. Greenbelt is being developed in the main plant, the corridor leading to the ash pond and around the ash pond. About 3.29 lakh saplings have been planted in and around the plant.
Power Evacuation
The power generated is evacuated at two levels i.e. 220 kV and 400 kV. Karnataka Power Transmission Company Ltd. (KPTCL) has commissioned the 220 KV transmission lines from the UPCL power plant to the substation at Kemar at a distance of 25 km.

- Certificate of Merit in Infrastructure /power Category – First place
- Certificate of Excellence in Large Scale Category – Third place
- Certificate of Commendations for its Meritorious Achievement
Fuel
The requirement of coal for these units is met through import. Udupi power plant procures coal through International Competitive Bidding (ICB) and spot purchases.
Water
Being a coastal area with perennial availability of seawater, it is used to meet the condenser cooling and other water requirements. Re-circulating type of circulating water (CW) system with natural draft cooling towers is installed. Desalination of seawater is carried out to meet the freshwater requirement for the plant.
Ash Management
Bottom ash is collected in silos in moist form and fly ash is collected in dry form in storage silos. For the fly ash agreement has been entered into with cement manufacturer for utilization of the fly ash. Unutilized ash is disposed at identified ash disposal areas.
