2003年全国电力供需总体偏紧,23个省级电网出现拉限电。全社会用电总计达到1889l亿千瓦时,比2002年增长15.3％,全国发电总装机38212万千瓦,缺额1500-2000万千瓦,电量缺额约350亿千瓦时。电力市场的主要特征可以概括为(1)用电增速进一步攀升,重型化用电结构十分明显。工业用电保持快速增长,轻、重工业用电格局发生变化;高耗能行业用电增长势头依然强劲。(2)电力供应能力新增总量创新高,增速相对滞后。截至2003年底,全国电力装机总量为3.01亿千瓦,净增装机超过3400万千瓦。全国共有220千伏及以上输电线路20.7万公里,变电设备容量6.1亿千伏
In 2003, the overall electricity supply and demand in the entire country was tight, and 23 provincial power grids were crimped. The total social electricity consumption reached 1889l billion kilowatt hours, an increase of 15.3% over 2002. The national power generation installed capacity was 382.12 million kilowatts, with a deficit of 15-2 million kilowatts and a power shortage of about 35 billion kilowatt hours. The main features of the electricity market can be summarized as (1) the further growth of electricity consumption, and the structure of heavy-duty electricity is very obvious. Industrial electricity maintained rapid growth with changes in the light and heavy industrial electricity grids. The growth of electricity consumption in the high-energy-consuming industries remained strong. (2) The total newly added capacity of power supply reached a record high, with a relatively slow growth rate. By the end of 2003, the total installed capacity of electric power in the country was 301 million kilowatts, with a net increase of more than 34 million kilowatts. There are a total of 207,000 km of 220 kV and above transmission lines nationwide with a capacity of 610 million KV substations
