我国清洁能源持续扩容(砥砺奋进的五年)

2017-08-26 04:11:56   中国青年网

本报北京8月25日电 (记者刘志强)记者近日从国家能源局获悉:党的十八大以来,我国能源结构显著优化,为推动能源革命、保护生态环境发挥了重要作用。到去年底,可再生能源发电装机容量达5.7亿千瓦,约占全部电力装机的35%;非化石能源利用量占到一次能源消费总量的13.3%,比2010年提高了3.9个百分点。目前,我国水电、风电、光伏发电装机容量已稳居全球首位。

水电持续扩容。十八大以来,我国新增水电装机约8300万千瓦,预计2017年底总装机约3.4亿千瓦,年发电量超过1.1万亿千瓦时。5年间,我国开工和投产了金沙江溪洛渡、向家坝等一批300万千瓦以上的大型水电站。其中,溪洛渡水电站装机规模居世界第三位。

风电领跑全球。2012年以来,我国新增风电装机容量连续4年居世界第一。截至去年底,风电累计新增装机容量8758万千瓦,成为煤电、水电之后的第三大电源。

光伏发电快速扩大。自2013年起,连续4年新增装机容量超过1000万千瓦。去年底,我国光伏发电累计装机容量达7742万千瓦,连续两年保持全球第一。

在快速发展可再生能源的同时,我国也加快了传统能源清洁高效利用的脚步。

煤电节能减排升级与改造稳步推进。到去年底,已累计完成超低排放改造4.5亿千瓦、节能改造4.6亿千瓦,分别占2020年目标的77%、73%。同时,煤炭清洁高效利用水平明显提升。在积极研发超超临界发电、煤基多联产等先进发电技术的基础上,我国火电机组平均供电煤耗已达321克标煤/千瓦小时,其中660—1000MW超超临界发电机组总装机已达1亿千瓦,居世界首位。新型煤气化、直接液化、煤制烯烃等技术也整体达到了国际领先水平。

各领域电能替代取得显著进展。为适应新能源汽车的逐步普及,我国加快了充电基础设施产业的发展。截至今年4月底,全国累计建成公共充电桩17.1万个。其中,城际高速快充站加快建设,已形成“六纵六横两环”格局。

成品油质量加快升级。今年1月1日起,全面供应国五标准车用汽柴油,我国长期以来“车好油劣”的状况得以改善,大气污染物排放有效减少。
