OPGC started as a solely owned Government Company of the state of Odisha.

The generation from these units is committed to GRIDCO based on a long-term Power Purchase Agreement.

With the divestment of 49% of the equity shares in favor of AES Corporation, in early 1999, the ownership structure of OPGC became the first of its kind in the country.

In 1990, OPGC started the construction of 7 Mini Hydel Projects in different locations of Odisha for the generation of pollution-free power by utilizing canal falls to meet the increasing demand for power with major funding from MNES and IREDA.

The land acquisition process for railway line and coal mine have been significantly advanced and the Stage-1 clearance has been obtained from the Ministry of Environment and Forest, Government of India for Forest Diversion for coal mine and MGR alignment.
