China's installed coal-based electrical capacity was 907 GW, or 77% of the total electrical capacity, in 2014.[25][26] The dominant technology in the country is coal pulverization in lieu of the more advanced and preferred coal gasification. China's move to a more open economy in the 1990s is cited as a reason for this, where the more immediately lucrative pulverization technology was favored by businesses. There are plans in place for an Integrated Gasification Combined Cycle (IGCC) type plant by 2010.[27] Furthermore, less than 15% of plants have desulphurization systems.[28]
