India’s new solar auction lights the way to Modi’s green targets

Record low Indian solar tariffs tendered at a groundbreaking auction may catalyze green investments and help tip the balance of new power to renewables and away from fossil fuels.

Solar power in India fell to a record 3.30 rupees (5 U.S. cents) a kilowatt-hour on Feb. 10 after a World Bank-backed auction helped the central Madhya Pradesh state tender 750 megawatts of power. The auction format, which included payment guarantees and was run by the state and central governments, could become a template fueling growth in other regions and bringing energy security to the world’s second-most-populous country.

“The outcome for this tender has shown that the holy grail of grid parity has been discovered,” said Basant Jain, the director at Mahindra Renewables Pvt., which won the right to build 250 megawatts of capacity in last week’s auction. If the auction can be replicated, it would unleash exponential growth in Indian solar and make it the cheapest source of energy available, he said.

India is among a growing list of countries stretching from Asia to Europe that have used auctions to make clean energy more affordable. The result should help Prime Minister Narendra Modi’s government meet pledges to install 175 gigawatts of renewable capacity by 2022 and spur discussion about whether solar can replace coal as India’s dominant source of energy.

The winning “bid brings the price of solar power in the same range as coal power,” said Ajay Mathur, a member of Modi’s Council on Climate Change, in an e-mail.

Template Ready

“When you’re given a full template-ready project you can get rid of variability,” said Manoj Kumar Upadhyay, founder of domestic solar developer Acme Group, which also won 250 megawatts in the auction. Without the template, bids may have been as much as 29 percent higher, he said in an e-mail response to questions.

The tender format, which attracted 20 bidders competing over 36 hours, may also provide a boost to indebted state-run power retailers, according to Bloomberg New Energy Finance. The lower electricity tariffs will be more attractive to loss-making distributors, some of which have struggled to buy enough electricity from clean power developers.

Concerns Remain

Concern remains among some industry analysts that the auction format may struggle to catch on or could erode developer profitability

“The fear is that media, government officials and analysts will hype up the low bids and other states will then start pressuring developers to match,” said Mercom Capital Group Chief Executive Officer Raj Prabhu in a statement.

ICRA Ltd., an Indian credit ratings agency, warned lower tariffs for developers may also hurt returns.

The levelized 3.3 rupee tariff looks “aggressive from an equity holders’ perspective and returns may likely be in single digits,” said ICRA’s head of power and renewables, Girishkumar Kadam, in an e-mailed response to questions.
