Tamil Nadu fails to cash in on solar power tariff crash
CHENNAI: Solar power tariff in the country has fallen by 80% since 2010. The maximum tariff for solar power was seen in December 2010 when 150MW was sold at 12.76 per unit under the Jawaharlal Nehru Solar Mission. Since then, the tariff has fallen steadily with the lowest tariff of 2.44 per unit for 500MW in Rajasthan.
The solar power tariff has been falling only when the states or agencies go through the bid mode. Tamil Nadu which followed the power purchase agreement does not figure in the list of states that took advantage of falling solar power tariff until 2015.
“Reduction in solar power tariff depends on several factors like solar irradiance, project cost, debt-equity ratio, cost of financing, return on equity, operation and maintenance cost,” said Union power minister Piyush Goyal in Lok Sabha on Thursday.
