Reliance Infrastructure is constructing a 5600 MW gas based Thermal Power Plant in the district of Dadri in the northern state of Uttar Pradesh. It is planned to be the single largest grassroot gas-fired generation plant in the world and solve much of the power supply shortages of northern India. The ADAG group was earlier in a bitter fight with Mukesh Ambani controlled Reliance Industries. On 15 June 2009 the Mumbai High Court ruled in favour of Reliance Natural Gas Limited.

Sasan UMPP along with the coal mine is the largest integrated coal-cum-power plant in the World. It is India’s first domestic coal-based UMPP. With an estimated cost of around Rs 20,000 Crores (US$ 4 billion), this is the single largest investment happened across any industry in India till date. Power generated from the project would be sold to 14 procurers in seven states of India at a levelized tariff. This UMPP will use super critical technology which results in higher operating efficiency and also reduces the carbon emissions thereby making it an environment friendly technology. It is expected to be fully operational in 2016.
