The Tamil Nadu Green Energy Corporation Limited (TNGECL) has made a big move to increase the use of renewable energy in government buildings all over the state. TNGECL put out a bid on February 27, 2026, asking developers to build 20 MW of grid-connected rooftop solar photovoltaic (PV) systems. The projects will be put up on different government buildings in Tamil Nadu to help the state make cleaner, more decentralised power.
Implementation under RESCO Model
The project will use the Renewable Energy Service Company (RESCO) model, which means that private developers will pay for the design, installation, and upkeep of the rooftop solar systems. Departments of the government won’t have to pay any installation costs up front. Instead, they will pay for the electricity that is made at rates set through a competitive bidding process. TNGECL thinks that this system of tariffs will give the state the best prices for solar power.
Net Feed-In Mechanism to Optimize Usage
A key feature of the initiative is the “Net Feed-In Mechanism.” Electricity generated by the rooftop solar panels will first be used by the host building. Any surplus power will be fed into the local electricity grid. The final electricity bill will reflect the net difference between energy consumed from the grid and energy supplied to it, reducing electricity expenses for government offices while also supporting grid stability and encouraging the use of green energy.
Tender Details and Administration
The Office of the Chief Engineer/NCES has sent out the tender under Specification No. CE/NCES/O.T No. 15/25-26. The project is run from TNGECL’s office in NPKRR Maaligai, 144, Anna Salai, Chennai. On the day the tender document was released, Anthony Raj signed it digitally, which officially started the bidding process.
TNGECL has given developers and stakeholders who want to take part their contact information. People who are interested can contact the Chief Engineer’s office to get more information about technical requirements, bidding procedures, or site information.
Focus on Clean Energy and Sustainability
This 20 MW rooftop solar project highlights Tamil Nadu’s continued commitment to renewable energy. By utilizing the rooftops of existing government buildings, the state aims to reduce carbon emissions, lower electricity costs, and increase renewable energy capacity without requiring additional land.
A TNGECL spokesperson said, “This initiative will help the state transition toward sustainable energy while ensuring cost savings for government departments and contributing to overall grid stability.”
