New Delhi: Renewable energy along with battery storage in Tamil Nadu is cost competitive with new coal power plants, according to a recent report.
It added that the cost of energy for a hybrid renewable energy battery storage system in Tamil Nadu would be Rs 4.97 per kilowatt hour (kWh) in 2021. The report studied a hypothetical RE-storage system for the analysis.
“The levelized cost of energy for a hypothetical hybrid renewable battery storage system for the state would be Rs 4.97 per kWh in 2021, which would falled to Rs 3.4 per kWh by 2030,” said the economic viability analysis by Climate Trends and JMK Research.
In comparison, the cost of electricity produced from new coal power plants in Tamil Nadu is between Rs 4.5 per kWh to Rs 6 kWh, it added.
According to the report, lithium-ion battery storage systems could also help reduce curtailment of renewable energy.
Close to 50 per cent of solar power in Tamil Nadu was curtailed since the lockdown in March 2020. Similarly, its curtailment of wind power in 2019 went up to 3.52 hours per day from 1.87 hours per day in 2018.
