Under development by Sasan Power, a wholly owned subsidiary of Reliance Power, the Sasan plant is claimed to be the largest integrated power plant and coal mining project in the world.

The five other units (each with 660MW of capacity) of the project have already been commissioned.

The Sasan UMPP is a pit-head coal-based power plant, and has been allocated three captive coal mine blocks — Moher, Moher Amlori extension and Chhatrasal.

Coal production has already started from the 20MTPA Moher and Moher-Amlohri mines.
