Pragati Power Corporation Limited, formerly Delhi Vidyut Board (DVB), was formed by the Government of National Capital Territory (NCT) of Delhi in 1997 for the purpose of generation and distribution of power to the entire area of NCT of Delhi.

To bridge the gap between demand and supply and to have reliable power supply to the capital city of Delhi, a 330 MW combined cycle Gas Turbine Power Project - Pragati Power Project (PPP) – was set up on a fast track basis. National Thermal Power Corporation (NTPC), the largest thermal power generating company of India, was the consultant for this project.

Raw water requirement in this plant is met through sewage treated water being drawn from various sources including a Sewage Treatment Plant. The demineralized water requirement for steam generation is met up through sewage treated water by treating it through Reverse Osmosis De-Mineralized Process (RODM).
