TANGEDCO Solar Net Metering in Tamil Nadu
The Complete Homeowner & Commercial Guide to Bi-Directional Net Metering in Tamil Nadu
TANGEDCO solar net metering connects your rooftop solar system to the Tamil Nadu power grid via a bi-directional smart meter. Surplus solar units generated during the day are exported to the grid, while nighttime electricity is imported. You are billed only for net consumption, and surplus exported units roll over as bill credits.

How TANGEDCO Bi-Directional Net Metering Lowers Your EB Bills
Under the Tamil Nadu Electricity Regulatory Commission (TNERC) Rooftop Solar Regulations, residential domestic consumers with grid-connected solar power plants are eligible for bi-directional net metering. When your solar panels generate more energy than your home consumes during sunny afternoons, excess units flow into the TNEB grid. Your bi-directional meter spins in reverse, building up valuable energy credits.
