中国电力企业联合会讯 2007年电力工业统计年报核算工作已于2008年7月底正式完成。近日,中电联秘书长、新闻发言人王永干正式签署发布2007年电力工业统计数据。统计数据总结概括如下:   

1、全国电力投资和基建新增继续保持较大规模
全年共完成电力建设投资5677亿元,同比增长7.36%,其中电源投资3226.27亿元。全年基建新增发电装机容量10190万千瓦,其中,水电、火电、核电和风电分别为1307、8360、200、304万千瓦。全年基建新增220千伏及以上变电容量18730万千伏安、输电线路长度41374千米。   

2、电力供应能力持续增强,发电量快速增长
截至2007年底,全国发电设备容量达到71822万千瓦,同比增长15.15%;其中水电、火电、核电和风电分别为14823.21、55607.42、884.6、419.89万千瓦,水、火电设备容量同比分别增长13.77、14.93%。 全国全年全口径发电量完成32644亿千瓦时,同比增长14.55%,其中水电、火电分别为4713.54和27206.59亿千瓦时,同比增长13.64%和14.6%。全国全年发电设备利用小时为5020小时,同比下降178小时,其中火电为5344小时,下降268小时。

3、输配能力继续提高,全社会用电高速增长
截至2007年底,全国共有35千伏及以上公用变压器容量242443万千伏安,输电线路回路长度1106345千米,同比分别增长了15.31%和7.46%,其中500千伏电压等级输电线路长度和变电容量同比分别增长了25.27%和37.85%。 全国全年全社会消费量达到32565亿千瓦时,同比增长14.80%;其中第一、二、三产业和城乡居民用电量分别同比增长3.83%、15.99%、12.85%和11.37%;工业用电量增长15.99%。

4、结构调整工作扎实推进
全国全年关停、退役机组规模空前,其容量达2336万千瓦,其中火电机组2043.91万千瓦。全国6000千瓦机组平均单机容量7.68万千瓦/台,比上年提高0.99万千瓦/台。

5、节能降耗工作成果显著
2007年,全国发电厂发电和供热生产消耗原煤14.38亿吨,同比增加1.24亿吨。全国6000千瓦以上电厂厂用电率下降0.10个百分点,为5.83%,供电标准煤耗下降11克/千瓦时,为356克/千瓦时。全国全年电力企业供电线损下降0.07个百分点,为6.97%。 2007年,我国电力工业在生产、基建投资和节能降耗等方面取得了丰硕的成果,同时也表现出了一些新的良好的发展趋势:电力生产、投资结构在不断优化,电力生产的能源转换效率在逐步提高,电力消费弹性系数在明显下降,电力消费能源占一次能源的比重有较大提升等,这些方面都充分证明电力工业认真贯彻落实科学发展观,努力走上一条又好又快的科学发展之路。 作为统计数据成果,中电联编写完成了《2007年电力工业统计资料汇编》和《中国电力工业统计数据分析(2007)》,分别从当年数据资料和近几年电力发展规律两个不同方面反映电力工业的基本情况。
