"The standards are part of China’s climate change plan for 2020. As part of the plan, 10 GW of inefficient coal-fired power plants will be closed while about 350 GW capacity will be required to improve operational efficiency. Additionally, new coal power plants will be have to restrict their average coal consumption to 310 grams per kWh of electricity generated. The limit for existing power plants will be 315 grams per kWh generated." (http://cleantechnica.com/2014/09/30/china-sets-coal-consumption-standards-power-plants/)
"In 2007, the State Council of China (SCC) issued notice of the closure of small thermal units in China, calling for a ‘progressive’ shut down during the period of the Eleventh Five-Year-Plan. Thanks to the economic incentives and other support measures, this policy plays a very important role in reducing GHG emissions. By the end of Eleventh Five-Year-Plan, China has shut down a total of 77.25 GW small coal units. By the end of 2013, an additional 14.08 GW thermal power units were shut down."

"The 2014 Coal Power Energy Saving and Emission Reduction Upgrade Action Plan
calls for near zero emissions of respirable particular matter, SO2, and NOx emissions for coal power plants, making emissions standards stricter than for natural gas fired plants. Some recently installed plants have already achieved this."
