TANGEDCO the state DISCOM of Tamil Nadu shall be floating tenders for wind and solar energy following tariff approval from the state. The ceiling tariffs for wind energy & solar energy are INR 2.65 & 3 per unit respectively. The tenders are likely to be floated in December. These maximum tariffs are being termed as lowest in the country. When developers will be bidding for these renewable energy projects their quoted tariff will be lesser than the limits fixed by TNERC.
The lowest solar energy tariff in India is INR 2.44 whereas for wind energy it is INR 2.43 per unit. One reason for fixing higher tariff for solar is the imposition of 25% safeguard duty. Another reason is that TNERC in its generic order has fixed the levellised tariff of wind energy to INR 2.86 per unit. The generic tariff of solar is INR 3.11. TANGEDCO would obviously want the renewable energy tariffs lesser than the generic tariffs.
The state DISCOM is purchasing wind energy at INR 2.75 per unit from its own plants. From other wind power plants, it has been purchasing energy at INR 3.08 per unit. On the contrary, it is purchasing solar energy at much higher rates-INR 6.85 per unit. As the cost of renewable energy from these sources are plummeting it is imperative for the DISCOM to install future solar or wind energy plants at a lower cost. The competitive bidding will help the DISCOM to achieve lower solar and wind energy cost.
Even TEDA is taking progressive steps to promote solar energy in the state
Lately, the nodal agency of Tamil Nadu TEDA has been taking steps to promote rooftop solar energy in the state. Tamil Nadu is the hub of educational institute. TEDA wants to utilise the terrace of these institutes for installation of the rooftop solar power plant. Size of these power plants will also be in excess of 1 MW something that SolarDae also advocates for.
