Mundra, Gujarat
Capacity: 4620 MW Type: Coal Based
Adani Power created history by synchronising India's first super-critical technology based 660MW generating unit at Mundra. The Mundra power project is also the fastest project implementation ever by any power developer in the country with a record completion of inception to synchronisation of the first unit within 36 months.
Phase III of the Mundra Project, which is based on supercritical technology, has received 'Clean Development Mechanism (CDM) Project' certification from United Nations Framework Convention on Climate Change (UNFCCC). This is the world's first thermal project based on supercritical technology to get registered as a CDM Project under UNFCCC.
Adani Power (Mundra) Limited, the Special Purpose Vehicle that was holding the Mundra power plant was amalgamated with its holding company Adani Power Limited in March 2023 under a Scheme of Amalgamation, with effective date of 1st October 2021.
Location
The Mundra plant is located in the Kachchh (Kutch) District in Taluka Mundra of Gujarat, comprising the villages of Vandh, Tunda & Siracha at a distance of about 61 kms south of the district capital Bhuj. The plant is near National Highway 8A and adjacent to the sea. Kachchh is a growing economic and industrial hub in one of India's fastest growing states – Gujarat. It is a mineral rich region with a large reserve of Lignite, Bauxite and Gypsum among other minerals. The Mundra power plant is located in the Mundra Port Special Economic Zone, on the northern coastline of the Gulf of Kutch. The Gandhi Dham railway station is located 50 km away. Mandvi airstrip (about 30 km), Kandla airstrip (about 45 km) and Bhuj Airport (about 70 km) are the airstrips/airports in the vicinity.
Plant Details
Plant capacity is 4620 MW, comprising four units of 330 MW and five units of 660 MW. The 330 MW units are based on subcritical technology and the 660 MW units are based on supercritical technology.
Design and development
Our Mundra plant sets global benchmarks for power producers in terms of size, efficiency and sustainability. Despite its enormous capacity, the facility stands unique in the world when compared with area per MW. Located on a very optimized layout of 734 Acres alongside auxiliaries like cooling towers, 47 MLD desalination plant and flue gas desulfurization plant (for the 3x660 MW Phase IV plant). The plant was constructed in 36 months - A record among Indian power developers. The plant was also the first to introduce the 660 MW supercritical power technology to India with the commissioning of its Unit # 5 in December 2010 following installation of four 330 MW units.
Power Evacuation, Purchase agreement
Power Purchase Agreement
APL's Mundra plant has long term Power Purchase Agreements (PPAs) with Gujarat and Haryana State DISCOMs and MPSEZ Utilities Ltd., the distribution licensee for the Mundra SEZ.
Power Evacuation
To help the utilities evacuate electricity from the plant and into the grid, Adani Power had constructed two power lines. The 433 km, 400 kV Mundra to Dehegam transmission line to transmit 1000 MW and the 989 km, 500 kV High Voltage Direct current (HVDC) bipole line with the capacity to transmit 2500 MW from Mundra to Mohindergarh in the northern state of Haryana. The latter is the first and longest HVDC system by a private player in India.

Fuel
The fuel requirement of the plant is met majorly through sourcing of imported coal. It also has an operational Fuel Supply Agreement of 6.405 MTPA with subsidiaries of Coal India Ltd.
Water
Mundra is India’s largest TPP to function off a sea-water based closed- cycle induced draft circulating cooling water system. The system draws on sea water that is recycled up to four times, conserving water and requiring a smaller discharge pipeline into the sea than an open- circuit cooling system.
Though seawater is used for the cooling system, other auxiliary systems use sea water purified by a reverse osmosis plant, that can produce 47 million liters of fresh water every day. Boilers require demineralized water, which is produced in Demineralization Plants. Each 660 MW boiler can convert more than 2000 MT of water per hour into steam that is at 250 times the atmospheric pressure and at a high temperature of 566o C steam is send to the turbine through high pressure pipes, after which it is collected & indirectly cooled in a condenser with sea water & recycled back to the boiler.
Ash Management
We established and commissioned an Ash bagging unit to achieve 100% Fly Ash utilization. For ensuring 100% utilization of Fly Ash, we have established a Fine Ash bagging unit at Mundra for bagging and disposal of fly ash generated due to our process. Each machine has an operational capacity of 18 TPH and the unit operates three such machines giving it a total capacity of 54 TPH.
