An energy crisis in two of Asia's key economies that caused power shortages and threatened slower growth is beginning to ease, though further risks remain.
Supplies of coal, the key source of electricity generation in China and India, are rising again after governments pressed miners to boost output. That's allowing power plants and major industrial consumers to start rebuilding stockpiles.
China's largest grid operator confirmed Sunday that supply and demand have returned to balance in its coverage area, about 88% of Chinese territory, though curtailments continue for some high-consuming, heavy-polluting industries in selected provinces. Spot power prices have tumbled in India as electricity shortfalls there have also been addressed.
"Both countries continue to face some risks in winter supply, but the shortages have moderated," said Xizhou Zhou, Washington-based managing director of global power and renewables at IHS Markit.
Global coal prices that had surged to records on the supply squeeze, swelling profits for miners like Glencore Plc and China Shenhua Energy Co., have cratered in recent weeks. High-quality thermal coal at Newcastle port in Australia -- a benchmark in Asia, the region that's the largest market for the fuel -- have tumbled more than a third since last month. Thermal coal futures in China have lost almost 50% since a dramatic rise through mid-October.
The turnaround in the region's energy supply follows a blitz of government interventions. Both China and India pushed state-backed miners to accelerate coal output. Authorities in Beijing have also moved to cap prices of the fuel, scrap some fixed rates for electricity, curb fuel exports and step up purchases of coal, gas and diesel from overseas.
That race to add more fossil fuels has also focused attention on a rebound in global greenhouse gas emissions this year, and on the vast challenge India and China have to overhaul their energy systems and meet emissions reductions targets they've outlined in recent days at the United Nations COP26 climate summit.
China's daily coal output has risen by more than 1 million tons in recent weeks to about 11.89 million tons and is expected to soon surpass a government target for production of 12 million tons a day. The ramp-up is exceeding expectations, and meaningfully reducing a supply deficit, Morgan Stanley analysts including Sara Chan said in research notes this week.
State Grid Corp. of China, which supplies power to about 1.1 billion people, said coal inventory has rebounded and that it now has about 20 days of available supply. China Southern Power Grid Co. said that on Thursday it didn't have to curtail electricity to users for the first time since May 10.
Coal inventories at India's power stations rose to 12.4 million tons on Friday from a low last month of 7.2 million tons. Major industrial consumers, who had coal supply limited as authorities prioritized power stations, are also seeing conditions improve.

Metals producer Vedanta Ltd.'s power stations had coal stocks for four to five days as of last week, up from the equivalent of a single day's supply at the peak of the crisis, Chief Executive Officer Sunil Duggal told reporters on an earnings call.
"Power shortages have been easing," said Michelle Leung, an analyst with Bloomberg Intelligence. "Everyone is ramping up their coal production. The speed has been quite impressive."
The crisis was triggered as a post-pandemic rebound in industrial activity added demand for electricity, just as coal supply declined in the two top-consuming nations. Output was crimped in India as heavy rains flooded key production hubs, while China has been reducing capacity and imposed stricter safety standards that lowered production rates.
Still, there are ongoing challenges. India's coal minister Pralhad Joshi has asked state-run miner Coal India Ltd. to ensure stocks at power plants reach an average 18 days worth of fuel by the end of this month, up from seven days supply as of Thursday.
Paper producers are running with less than half their typical coal reserves, according to A.S. Mehta, president of the Indian Paper Manufacturers Association and a director at JK Paper Ltd., one of the country's largest suppliers. While operations haven't been disrupted, companies faced a "sizable impact" on costs because of the need to compete in Coal India auctions or to turn to expensive imports, he said.
In China, some utilities haven't completed winter restocking and insist there's only limited additional supply available. State Grid plans to closely track coal and gas supply and expects there'll be "overall tight balance with partial gaps" on the network this winter and in spring, according to the company's Sunday statement.
Demand for heating is expected to rise as China encounters a cold snap that could see temperatures drop by eight to 10 degrees Celsius, according to the nation's weather office. Heavy snow has already disrupted flights and rail services, with blizzards forecast for northern China including Inner Mongolia, a key coal region. Central and eastern regions are expected to be colder in January and February than a year ago as a result of the La Nina phenomenon.
"Policy measures are mitigating the power shortage risk," said Lara Dong, IHS Markit's head of greater China power and renewables research. "It remains to be seen whether the risk can be entirely eliminated during this winter."
