China approves biggest expansion in new coal power plants since 2015, report finds

Concerns about energy shortages drive increase as projects progress at extraordinary' speed

China approved the construction of another 106 gigawatts of coal-fired power capacity last year, four times higher than a year earlier and the highest since 2015, research shows.

Over the year, 50GW of coal power capacity went into construction across the country - up by more than half compared with the previous year - driven by energy security considerations, the Centre for Research on Energy and Clean Air (CREA) and Global Energy Monitor (GEM) said on Monday.
