> Even as China’s coal demand is falling, the output from domestic coal mines is increasing rapidly. This resulted in a major overall drop in coal imports in the first quarter of the year, as reported by China Customs, and allowed coal plants and other operators to fill up stockpiles that were depleted during last year’s coal shortage.
> Investment in new coal- and gas-fired power capacity is also continuing at a high level. In the first four months of the year, at least 18 thermal power projects started construction, with a total capacity of 12.8 gigawatts (GW). Another 19 projects with a total capacity of 13.0GW were approved for construction.
