The cost of solar power generation in India has fallen to half the level seen in many other markets in the region due to extensive solar resource, market scale and competition.
“The country has seen [the] levelized cost of electricity (LCOE) using solar falling to $38/MWh this year, which is 14% cheaper than … traditional coal-fired electricity,” read a report by U.K.-based market intelligence firm Wood Mackenzie.
Solar capacity in India is expected to touch 38 GW this year and the expanding market scale, coupled with high-quality solar resources and competition, has pushed solar costs down to half the level seen in many rival Asia Pacific countries – according to WoodMac research director Alex Whitworth.
The trend is spreading across the region, however, with Asia Pacific set to see solar directly compete with coal by 2027.
Australian solar to beat coal next year
Solar power in the second cheapest Asia Pacific market of Australia – a nation which has been historically reliant on cheap and abundant coal and gas for power generation – is already cost-competitive against gas with the LCOE for solar having fallen 42% in three years. Solar is expected to break through the coal-fired electricity price barrier next year, when its cost falls to US$48/MWh.
Significantly, Australia’s rising volume of gas exports is pushing domestic prices for the fossil fuel higher at the same time as environmental regulations restrict the use of coal.
“Maintaining grid stability and reducing curtailment of intermittent generation has been a recurring challenge in Australia,” said Whitworth, who suggested energy storage would be one of the key options available to help balance power demand with maintaining uninterrupted supply.
Regional tipping point in 2027
While solar power costs are falling across the Asia Pacific region, the average LCOE for wind and solar is still 29% higher than for coal-fired power. Wood Mackenzie forecasts that premium will vanish by 2027, fueling direct competition between renewables and coal.
By 2030, renewable power generation across the region will cost around 17% less than coal-fired power, with exceptions in Malaysia, Indonesia and Japan, where renewables will remain more costly.
Whitworth added: “Lower costs will boost wind and solar generation’s share of the power mix from the current 6% to a much higher level in [the] coming years. This will create both opportunities and disruption in the industry.”
