The policy will be applicable to projects, programs and installations relating to PV and solar thermal energy, in a state that ranks fifth nationally for solar.
The draft policy mandates 2022 goals including having all public buildings, street lights and the water supply installations of corporations, municipalities and local urban bodies meet 30% of their energy requirements from solar. Within four years, the draft policy envisages all state government departments replacing 10% of their vehicle fleet with solar-powered electric vehicles.
To establish a solar ecosystem, the Tamil Nadu Energy Development Agency (TEDA) has announced several incentives including an exemption of solar from electricity tax and grid connectivity, open access, wheeling, banking and cross-subsidy charges. Joint utilisation of land for solar projects, crops and rainwater harvesting has also been mooted.
Solar manufacturing ambition
Under the policy, the Tamil Nadu government would promote the manufacture of cells, inverters, mounting structures and batteries. Land would be identified for the development of production lines and a one-stop-shop created for technical and funding support and project clearance.
To ensure the compliance of electricity distribution companies with the Renewable Purchase Obligation (RPO), the policy mandates strict enforcement of penalties specified by the Tamil Nadu Electricity Regulatory Commission (TNERC).
The commission would also determine the solar energy gross and net feed-in tariffs to incentivise solar power export to the grid at times of peak demand.
Tamil Nadu’s Kamuthi solar facility is listed among the world’s eight largest solar power plants by installed capacity. Spread over 2,500 acres and incorporating 2.5 million solar panels, the plant has a total generation capacity of 648 MW. Completed in September 2016 at a cost of approximately $679 million, the plant is cleaned daily by a robotic system, charged by solar panels.
