Godda, Jharkhand
Capacity: 1600 MW Type: Coal Based
The 1,600 MW (2x800 MW) Godda Ultra-Supercritical Thermal Power Plant of (USCTPP) Adani Power (Jharkhand) Limited (APJL), a subsidiary of Adani Power Limited, is the largest thermal Independent Power Project (IPP) of Jharkhand. It has been set up in a sector-specific Special Economic Zone (SEZ) for power.
The Godda USCTPP represents a unique model of cross-border exports of electricity. It is the first thermal power plant exporting its entire power supply to the neighboring country of Bangladesh over a 130km long, 400kV cross country Double Circuit transmission line, connected exclusively and directly to the Bangladesh grid.
The first 800 MW unit of the plant was commissioned on 6th April 2023 and the second 800 MW unit of the plant was commissioned on 26th June 2023.
Location
The Plant is located at Motia, Patwa in Godda district of Jharkhand state. Nearest railway station is Godda at distance of 6km from the plant. The nearest Airport is Deoghar at distance of 84km from the plant, while the nearest Sea Port is the Dhamra Port in Odisha at distance of 695km by rail route.
The maximum ambient temperature at plant location is about 47°C and annual mean relative humidity is 58% to 68%. The Plant is located at Latitude & Longitude of 24° 48' 41.07"N & 87° 08.5' 12.23"E.
Plant Details
APJL’s plant employs Ultra-Supercritical technology for power generation. It operates at Pressure & Temperature of 27.57 MPa, and 605 ℃. The Turbine Consist of Single Flow HP turbine, One Double flow IP turbine and Two Double Flow LP turbine.
A Limestone-based Wet Flue Gas De-Sulphurization (FGD) System is installed to manage the SOx emission levels at less than100mg/NM3. A Selective Catalytic Reactor System (SCR) is installed to reduce the NOx emission levels. Zero Discharge concept will be followed for water use to avoid any thermal impact on aquatic ecosystem.
The plant is located on 550 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, FGD etc.
Power Supply Agreement
The plant has a 25-year, long term power purchase agreement with Bangladesh Power Development Board for net capacity of 1496 MW, representing its entire gross capacity of 1600 MW. Godda is unique among power plants globally, wherein the plant is not connected with the host country’s grid and 100% of the generated power is supplied to the procuring country through a dedicated transmission line.
Fuel
Coal is received at the plant by rail wagons, where it is offloaded using two Single-wagon Tipplers. The coal yard has two stacks for storage of coal.
Water
APJL has a water supply agreement with Jharkhand Government to bring water from River Ganga up to the plant. The makeup water pump house installed on river at Sahib Ganj draws water from the source. A pipeline of 96km length along the route has been laid to ensure uninterrupted supply of water to two reservoirs. It crosses eight river spans, three National Highways and three locations of Railways up to the power plant. The water from ganga 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.
Ash Management
Fly ash from ESP & APH is sent to Main ash silo/HCSD Silo by Vacuum- cum- Pressure type system. The APJL plant has achieved 100% fly ash utilization through supply of fly ash to cement plants. Jet pump system is provided to convey the slurry from BA hopper of each unit to ash slurry pump house. Slurry Pumps further convey BA slurry to Hydro-bins. Settling tank and Surge tank of steel is provided (in plant) for re-circulation of BA overflow water and decanted water from Hydro-bins for re-use in the Ash Handling System. The plant is equipped with latest pollution control equipment such as high efficiency electrostatic precipitators, FGD and SCR for controlling emissions.
