Tamil Nadu is getting set to take up over 50 infrastructure projects worth over ₹45,000 crore, for which the bids will be out in next 1-2 years. Among others, these include the upcoming greenfield airport at Parandur, two pump storage projects, and a thermal power project near Chennai.
All these large scale projects will be under the public-private-partnership mode, sources said. There are transmission projects; 24X7 water supply projects, a desalination plant, industrial infrastructure and waste-to-energy project, they added. Large projects are expected to take 5-6 years for completion, while the smaller ones would take two years.
The largest among the PPP projects would be the Centre giving its in-principal approval for the Parandur project, the bid is under preparation for the project to be taken up at around ₹20,000 crore.
The State government in the 2025-26 budget said that Tamil Nadu’s power demand is expected to double as the State aims to become a trillion-dollar economy by 2030. To meet this ambitious target, strategic action plans are being developed to generate an additional 100 billion units of renewable green energy by 2030.

As the first step in this journey towards green energy, Pumped Storage Projects with a capacity of 1,100 MW in the Vellimalai area and 1,800 MW in the Aliyar area will be developed through Public Private Partnership (PPP) mode, with a total investment of .₹11,721 crore. The bid documents are being prepared for these two projects, which would be important for the State, said sources.
Pumped storage project is a type of hydroelectric energy storage that utilises two reservoirs at different elevations to store and generate electricity by moving water between them. Tamil Nadu has a 4 X 125 MW pumped storage hydroelectric project at Kundah in the Nilgiri Hills. This is expected to be commissioned by November this year, sources said.
Bids will also be called for a thermal power project in North Chennai of 1 X 660 MW capacity. This project will cost around ₹7,000 crore, sources said.
