Solar power grid parity seen by 2019-20: report

New Delhi: Solar power in India could cost the same as conventional electricity by 2019-20, a report said on Tuesday, which could boost the use of an energy source regarded as key to curbing emissions in the world’s third-worst carbon polluter.

A KPMG report said more aggressive policy could see solar power prices decline at a rate of 5-7% annually over the next decade, ensuring “grid parity", or the point when solar power costs the same as conventional power, as early as 2017-18.

Such targets are well in line with India’s plans to produce 20 gigawatts (GW) of solar power by 2022, though hurdles such as steep production costs, lack of data and trained manpower remain.

“The pace at which the gap between solar power tariffs and the landed cost of power will be bridged will determine the pace at which solar power will take off," the report said.

“While we expect grid parity for these consumer categories -- domestic and agriculture -- in 2019-20, based on state-specific and end-use specific cost economics, the adoption of solar is likely to happen earlier."

It said certain states such as Rajasthan, Gujarat and Tamil Nadu could reach grid parity earlier than others because of more favourable policies and sunnier weather, thereby reducing costs.

Also, conventional power costs are higher in these states as they are located far away from coal reserves.

Coal, available in abundance in India, provides power at about Rs2 (4 cents) a unit, compared to a kilowatt-hour of solar power at a range of Rs11 to 12.

According to the Indian Solar Mission, introduced in 2009, solar power output by 2022 would be equivalent to one-eighth of India’s current installed power base, helping Asia’s third-largest economy limit its reliance on coal to power annual growth of 8-9%.

The KPMG report said solar energy could contribute to about 7% of India’s total power needs and displace about 16,900 megawatts (MW) of conventional power by 2022, and with additional solar capacity, could cut India’s total coal imports by 30% by that year.

“Furthermore, solar power can save 95 million tonnes of CO2 equivalent per annum by 2022," it said, which would mean a cut of about 2.6% of the country’s total emissions in that year.

In 2009, India set a goal for slowing the growth of its emissions, saying it will try to rein in its “carbon intensity" -- the amount of carbon dioxide emitted per unit of economic output -- by between 20 and 25% by 2020, from 2005 levels.

It is now the world’s No. 3 greenhouse gas polluter after the United States and China, and rapid economic growth and consumption are driving up production of planet-warming carbon dioxide from coal-fired power plants, transport and industry.

Its current per-capita emissions stand at 1.8 tonnes, about a third of China’s and less than a tenth of the United States’.
