BEIJING, Oct 21 (Reuters) - China's thermal coal futures fell by their trading limit for the third evening session in a row on Thursday, extending losses triggered by signs Beijing may intervene to cool surging prices and ease a widespread power crunch.
China is pushing miners to ramp up coal production and is increasing imports so that power stations can rebuild stockpiles before the winter heating season, but analysts say shortages are likely to persist for at least another few months.
The state planner, the National Development and Reform Commission (NDRC), said on Tuesday it was studying ways of intervening to lower coal prices and would take all necessary steps to bring them into a reasonable range.
At the start of Thursday's night session on the Zhengzhou Commodity Exchange, the most-active thermal coal futures contract, for delivery in January, plummeted the maximum 14% to 1,365 yuan ($213) per tonne.
That came after the contract finished day-time trade down 11% and brought the overall decline in prices since Tuesday's all-time peak of 1,982 yuan to more than 31%.
The contract was trading down 10.6% at 1,420 yuan as of 1354 GMT, still up almost 170% year-to-date.
Coking coal and coke futures on the Dalian Commodity Exchange were both trading around 6% lower on Thursday evening, having fallen by the maximum 12% in day-time trade.
Despite recent swings in coal prices, higher energy, labour and other costs are now expected to persist and be passed on to end-consumers, economists and analysts have said. read more
Chinese law allows the State Council, the country's cabinet, and regional governments to limit profit rates and set price limits when prices for important goods or services rise sharply, the NDRC said earlier this week. It vowed to crack down on any irregularities and maintain market order. read more
On Thursday, the NDRC said it had mobilised its regional arms as well as key coal enterprises to conduct a special survey on coal output and distribution costs and prices as part of its research into how to intervene. [nP8N2RE02D

China Energy Group, the country's top coal miner and largest power producer, said on Thursday that its coal output from Oct. 1 to 20 increased by about 2.26 million tonnes, or 7.5% compared with the same period last year.
The state-owned mining and energy company added that total power generation in the same period was 54.78 billion kilowatt hours (kWh), up 15% year-on-year, of which thermal power generation rose by 6.36 billion kWh, up 17.2%.
China's securities regulator has asked futures exchanges to raise fees, restrict trading quotas and crack down on speculation in response to high coal prices.
The government took its boldest step in a decade of power sectors reform by allowing coal-fired power plants to pass on the high costs of generation to some end-users via market-driven electricity prices from Oct. 15. read more

Beijing has been trying to reduce its reliance on polluting coal power in favour of cleaner wind, solar and hydro.
Citi analysts expect China's coal-fired power generation will drop 86% from 4,658 million megawatt hour (MWh) in 2020 to 653 million MWh in 2060 as cleaner energy plants come online.
China's State Grid said on Wednesday that coal stocks at power plants in the northeast had climbed to 78% of last year's level as of Oct. 16, but it did not provide outright volumes.
The three northeastern provinces of Jilin, Heilongjiang and Liaoning were among the worst hit by the power shortages last month.
Several regions in northern China, including Inner Mongolia and Gansu, have already started winter heating, which is mainly fuelled by coal, to cope with the colder-than-normal weather.
In late October, temperatures in central and eastern regions are expected to be "significantly lower than normal," the National Meteorological Center forecast on Thursday. Itadded that temperatures in some western and southern regions of the country will fall by 4 to 10 degree Celsius within the next day.
