basic realization of the supply-demand balance. \economy has entered a new round of growth cycle. Associated with this, the rapid growth of the national electricity demand, electricity supply shortages re-emerged in 2003 in 2004, gradually developed into a nationwide, continuous power shortage situation. Among them, 2003, a total of 23 provincial power grids implemented; 2004, a total of 26 provincial power grids implemented. Since the new century to face the most serious shortage of power supply and demand in the new situation, the CPC Central Committee and State Council attached great importance to increased macro-control efforts; power enterprises has accelerated the pace of power construction, increase cross-provincial electricity trade, the demand for active side management measures, with less than three years to reverse the country's electricity supply tensions.
In 2004, National City customers as a result of power blackouts caused the average time for 9 hours and 25 minutes; in 2005 dropped to 6 hours and 55 minutes; to continue in 2006 reduced to 18 minutes; first half of this year, only 6 minutes. This shows that the tension in the national electricity supply has been effectively alleviated.
2. Safe and stable operation of power has improved continuously. Over the past five years, the National record high power load. In order to ensure electrical safety of sustained and stable production, the electricity system in the building and equipment to strengthen management, improve the network of factory co-ordination mechanisms, the development of contingency plans and regular safety drills, etc. have done a great deal of solid work to further solidify the power of the safety management basis. There were no major national electricity production more than personal injury and death, there were no serious incidents grid, there were no major equipment accidents, the general power grid power production safety accidents and equipment significantly reduce accidents. From 2004 to 2006, the national power grid from accidents dropped from 196 to 48, the equipment from accidents dropped from 551 to 238 since a timely manner to avoid the possible large-scale, long-term power outage.
3. Power construction by leaps and bounds, \Congress\has realized the power capacity of 400 million kilowatts, 500 million kilowatts, 600 million kilowatts a landmark three major leaps and bounds. Installed a four-year average annual growth rate of 15%, since the reform and opening than the average annual growth rate of 6.41 percent high. Since 2002 in particular, to increase the power capacity of close to the sum of the previous 52 years, this is the speed of China, the pace of the world. The end of 2006, the national power generation installed capacity reached 624 million kilowatts installed capacity and power output for 12 consecutive years has ranked second in the world. The end of 2007, national power installed capacity will reach 700 million kilowatts.
Five years, the rapid growth of installed capacity of hydropower smooth, with an average annual increase of 11 million ~ 13 million kilowatts about. The end of 2006, installed hydropower capacity reached 130 million kilowatts, ranking first in the world; thermal power reached 484 million kilowatts of electricity supply more obvious role in protection; the development of wind power into the high growth period, as of 2006 the end of the formal and the national transport network for wind power equipment capacity of 2,072,500 kilowatts, representing 420 percent growth in 2002, an average annual increase of 50%, especially in the year 2006, installed capacity of wind power production is equivalent to the sum of the past history ; biomass power generation to start, as at the end of 2006, the National has built a total of 80,000 kilowatts national demonstration projects generating units straw to fill the gaps in China's power generation straw.
4. Power continued to strengthen and improve the power grid is continuously increasing, regional, provincial power grids have been the main network to achieve further development. Over the past five years, China's power grid, and more than 220 kV line length of more than 100,000 km, which is equivalent to the founding of new China since the sum of the previous 45 years. The end of 2006, 220 kV and above transmission line length increased to 28.64 million meters, the average annual growth rate of 10.99%; transformer capacity increased to
964.05 million kVA, with an average annual growth of 16.29%. Most parts of the country have formed a 500 (330) kV main grid-based grids, the north-west to Lanzhou Guanting East 750 kilovolt power transmission project in operation, shows that China has the highest voltage power transmission to a new level . Shape the pattern of national network, optimize the allocation of resources to promote play an important role. Expanding the scale of electricity, as at the end of 2006, the three-channel transmission from west to east to form a total of 34 million kilowatts of transmission capacity.
Peak load of the grid reaching new heights. Following the East China Power Grid has become the first country, the world's second breakthrough in a load of 100 million kilowatts of regional power grids, the North China Power Grid has also been a breakthrough load 100 million kilowatts. Guangdong, Jiangsu, Shandong provinces EC peak load transfer 30 million kilowatts a breakthrough; Shanghai became the first EC breakthrough tune peak load of 20 million kilowatts and municipalities; Beijing's unification peak load transfer has been more than 12 million kilowatts; Suzhou EC calls and Shenzhen to become electric load of more than 10 million kilowatts cities.

1.电力供需形势得到有效扭转,基本实现了供需平衡。\十六大\以来,我国经济进入新一轮增长周期。与此相伴,全国电力需求增长迅猛,电力供应短缺状况再度出现,2003年、2004年逐渐发展成全国性、持续性缺电局面。其中,2003年,全国先后共有23个省级电网实施了拉闸限电;2004年,全国先后共有26个省级电网实施了拉闸限电。面对进入新世纪以来最为严重的电力供需紧的新情况,党中央、国务院高度重视,加大了宏观调控力度;电力企业加快了电力建设步伐,加大跨区跨省电力交易,积极采取需求侧管理措施,用不到三年的时间就扭转了全国电力供应紧局面。
2004年,全国城市用户由于缺电原因造成的停电时间平均达到9小时25分钟;2005年下降为6小时55分钟;2006年继续降为18分钟;今年上半年,只有6分钟。这表明全国性供电紧形势得到了有效缓解。
2.电力安全稳定运行水平不断提高。五年来,全国电力负荷屡创新高。为保证电力安全生产的持续稳定,各电力企业在加强系统建设和设备管理、完善网厂协调机制、制定安全应急预案和定期演练等方面做了大量扎实的工作,进一步夯实了电力安全生产管理的基础。全国没有发生重大以上电力生产人身伤亡事故,没有发生特大电网事故,没有发生特大设备事故,电力安全生产一般电网事故和设备事故大幅度减少。2004~2006年,全国电网事故由196起下降为48起,设备事故由551起下降为238起,及时避免
了可能出现的大面积、长期停电事故。
3.电源建设取得跨越式发展\十六大\以来,电力装机实现了4亿千瓦、5亿千瓦、6亿千瓦三次大的标志性跨越。四年年均装机增长15%,比改革开放以来年均增长率高6.41个百分点。特别是2002年以来,增加电力装机接近于前52年的总和,这是中国的速度,也是世界的速度。到2006年年底,全国发电装机容量达到6.24亿千瓦,装机容量和发电量已经连续12年位列世界第二位。到2007年年底,全国电力装机容量将达到7亿千瓦。 五年中,水电装机容量平稳快速增长,年均增加1100万~1300万千瓦左右。到2006年年底,水电装机容量达到1.30亿千瓦,居世界首位;火电达到4.84亿千瓦,对电力供应的保障作用更加明显;风电发展步入高速增长期,截至2006年年底,全国正式并网投运的风电设备容量207.25万千瓦,比2002年增长420%,年均增长50%,特别是2006年一年投产风电装机容量相当于以往历史的总和;生物质发电开始起步,截至2006年年底,全国已建成共8万千瓦国家级秸秆发电示项目机组,填补了我国秸秆发电的空白。
4.电网不断强化和完善电网规模不断扩大,区域、省电网主网架得到较大发展。五年来,我国电网220千伏及以上线路长度增加10万多千米,相当于新中国成立以来前45年的总和。到2006年年底,220千伏及以上输电线路长度增长到28.64万千米,年均增长10.99%;变电容量增长到96405万千伏安,年均增长16.29%。全国大部分地区已经形成了500(330)千伏为主的电网主网架,西北地区官厅至东的750千伏输变电工程投产,标志着我国输变电最高电压等级提高到了新的水平。全国联网格局初步形成,对促进资源优化配置起到了重要作用。西电东送规模不断扩大,截至2006年年底,西电东送三大通道累计形成3400万千瓦的输送能力。
各电网最高用电负荷屡创新高。继华东电网已经成为全国第一个、世界第二个用电负荷突破1亿千瓦的区域电网后,华北电网用电负荷也已经突破1亿千瓦。、、三省统调最高用电负荷突破3000万千瓦;成为第一个统调最高用电负荷突破2000万千瓦的直辖市;的统调最高用电负荷也已经超过1200万千瓦;和成为统调用电负荷超过1000万千瓦的地级城市。
发展展望
●与国民经济发展相适应,适度超前发展; ●把握机遇进行结构调整,实现可持续发展; ●协调有序共赢,实现和谐发展。
1.供需仍将继续保持旺盛态势,电力需要适度超前发展
