中國凱迪生態與環境技術股份有限公司(Kaidi Ecological And Environmental Technology Co. Ltd.)在華東的安徽省及中國東北的吉林省引進了兩座專燒生質物的電廠。

經過一連串的試運轉之後，於2月12日起在安徽省正式啟用發電量為3仟萬瓦的電廠。隨後，吉林的中國華電以同樣規模的生質能發電廠開始運轉。華電於2月4日完成了測試。而華電正在計劃另一個未指明時間的3仟萬瓦的生質能鍋爐發電機組。

目前凱迪擁有47座生質能發電廠，總裝置發電量為1,392百萬瓦。其重點項目為從附近地區收集農作物殘渣來焚燒。

此計畫符合了中國政府鼓勵使用生質能和其他可再生能源以取代燃煤發電及產熱的規劃，以減緩空氣污染。但去年2月，中國相關部門對木質顆粒燃料進行了禁止進口的禁令，以促進國內的生質物料之貿易與去化。

中國政府於2016年底推出了“十三五”計劃，強調到2020年生質能發電量將達到150億瓦的目標。但中國國家可再生能源中心後來呼籲，到2020年該目標將提高到300億瓦，以滿足中國對巴黎協議的承諾。巴黎協議旨在將全球的溫度上升限制在工業化前平均溫度以下的2°C以下。

中國政府已經分別推出了一系列計劃，通過在北京、天津及其他26個位於河北、山西、河南、山東等北方省份的其他城市推廣使用生質能和其他清潔能源，減少冬季住宅供暖用煤。但該計劃必須修訂，因為今年冬季的地區電力短缺導致更多的燃煤發電，因此，燃煤再次被允許用於住宅用途。

China’s Kaidi adds to biomass power plants

Chinese utility Kaidi Ecological and Environmental Technology has brought on line two dedicated biomass-fired power plants in east China's Anhui and northeast China's Jilin provinces.

The 30MW plant at Congjiang in Anhui started operations after finishing trial tests on 12 February. This followed the start of operations of its similar size biomass power plant at Huadian in Jilin. Huadian completed trial tests on 4 February. Another 30MW biomass boiler unit of an unspecified timeframe is being planned for Huadian.

Kaidi now operates 47 biomass power plants with a total installed capacity of 1,392MW. Its projects are focused on burning crop residue from nearby areas.

The utility's move is aligned with China's plan to encourage the use of biomass and other renewable energy sources, in place of coal for power and heat generation, in a bid to tackle air pollution. But authorities in February last year imposed an import ban on wood pellets for combustion purposes, in a bid to boost domestic biomass trade.

The Chinese government rolled out its 13th five-year plan at the end of 2016, highlighting a 15GW target for biomass-fired power generation capacity by 2020. But government agency the China national renewable energy centre later called for this target to be raised to 30GW by 2020 to meet China's commitments to the Paris climate agreement. The Paris agreement aims to limit the global temperature increase to below 2°C above pre-industrial levels.

The government has separately rolled out a plan to reduce the use of coal for winter residential heating by promoting the use of biomass and other cleaner energy sources in Beijing, Tianjin and 26 other cities in the northern provinces of Hebei, Shanxi, Henan and Shandong. But the plan had to be revised as regional electricity shortages this winter saw more coal-fired power generation allowed again for residential use.
