Sasan Ultra Mega Power Plant or Sasan UMPP is one of the four Ultra Mega Power Projects awarded by the Ministry of Power, Government of India. It is located in Sasan village near Waidhan in Singrauli district of Madhya Pradesh. Sasan UMPP is India's largest integrated power generation and coal mine project with 3,960 MW power plant and 20 MT per year coal mining capacity. It is presently the 4th largest electricity generation power plant in India after NTPC Vindhyachal (4,760 MW), Mundra Thermal Power (4,620 MW) and Mundra UMPP (4,000 MW). The total project value of Sasan UMPP is ₹25,186 crores (₹251.86 Billion). The plant is estimated to have been one of the ten most carbon polluting coal-fired power plants in the world in 2018, at 27.2 million tons of carbon dioxide, and relative emissions are estimated at 1.4 kg per kWh. History The plant is operated by Sasan Power Limited (SPL), a subsidiary of Reliance Power Limited. SPL was incorporated on 10 February 2006. The Letter of Intent (LoI) was awarded to Reliance Power on 01 August 2007 and the Power purchase agreement (PPA) was signed on 07 August 2007. As of March 2020, it provides electricity to 13 million customers across 7 states of India. The Engineering, procurement and construction (EPC) contract was given to Reliance Infrastructure. In terms of Plant Load Factor among all thermal power plants in India, Sasan achieved “Numero Uno” position in the country for 4th year in a row. Coal Mines The Sasan UMPP is a pit-head power project, which has been allocated 3 captive coal mine blocks: Moher, Moher-Amlohri extension and Chhatrasal in Singrauli, Madhya Pradesh. Reserves are in excess of 750 million tonnes. Together, the mines produce 20 million tonnes of coal each year, making it the largest integrated power plant and coal mines project in India. Installed capacity Following is the unit-wise capacity of the 3,960 MW plant. There are 6 units of 660 MW each.
