India : T.N. to harness rooftops for solar energy

Tamil Nadu government is planning a massive solar energy programme through setting up of grid-connected rooftop solar panels in government buildings.

The plan is to tap 25,000 buildings, including educational institutions, which offer 2 crore square feet of rooftop space with a potential capacity of 110 MW at an outlay of ₹940 crore, according to a document available with The Hindu.

The move follows an announcement by Electricity Minister P. Thangamani in the Assembly.

Tamil Nadu Energy Development Authority (TEDA) will be the nodal agency for implementation. Its role will include selecting vendors for implementing the project, looking at various financing options for the project and ensuring co-ordination with various stakeholders.

“This is the first big scale attempt on solarisation not only in Tamil Nadu, but also in India. It shall lead to substantive savings to the government with zero upfront investment,” said a TEDA official.

According to a rough calculation, a government building in a district by implementing a 130.82 kW system can save over ₹5 lakh in self-consumption charges and earn income of over ₹2 lakh through sale of surplus power to Tamil Nadu Generation and Distribution Corporation (Tangedco). The agency will run pilot projects in a few selected districts. Ramanathapuram, Coimbatore and Salem have been shortlisted for the pilot project. TEDA has called for proposals from vendors for 50 MW of project worth ₹250 crore. The vendor shall run the project on a BOOT model (Build Own Operate,Transfer).
