Energy supplies including coal and oil are largely sufficient in China as a majority of mines and refineries have resumed operation, the National Development and Reform Commission (NDRC) said on February 23.

As of February 20, coal stockpiles at the country's plants were adequate for 27 days of consumption, while those in Hubei, the epicenter of the novel coronavirus outbreak, were sufficient for 54 days of use as of February 22, according to information from a press conference on February 23.

By February 22, the coal sector was running at 76.5 percent of capacities, which reached 3.17 billion tonnes. On February 22 alone, output came in at 8.33 million tonnes, doubling the production on February 1.

Stocks of both refined oil and natural gas remained high, with oil stockpiles exceeding 21.1 million tonnes by February 21.

The NDRC pledged to closely monitor supply-demand changes in the energy sector as demands are set to pick up with more business restoring activities.
