1~8月,全国电力供需总体平衡,8月受持续极端高温气候影响,华东等部分地区在高峰时段出现少量电力缺口,通过采取错避峰措施,未出现拉闸限电情况。全国用电市场延续2012年以来中速增长态势,8月全社会用电量增速比上月明显回升,城乡居民生活用电量高速增长。上半年水电多发、火电发电量低速增长,但7月以来全国水电发电量连续两个月同比负增长,大部分水电大省水电发电量负增长,为火力发电留出了市场空间,加上高温炎热负荷激增,全国火电发电量增速接近20%;水电、火电、核电设备累计利用小时均比上年同期回落,风电发电量快速增长、设备利用小时同比明显增加。电网投资同比快速增长,电源投资同比实现正增长,但火电、核电投资同比下降幅度较大。基建新增发电装机容量较上年同期增长超过三成,水电新增规模创同期新高,火电在建规模同比大幅减小、但
From January to August, the overall electricity supply and demand in the country was in balance. In August, it was affected by the continuous extreme high temperature. In some areas such as East China, there was a small amount of power shortage during peak hours. No power outage occurred during the peak-off period. The national power market continued its medium-speed growth since 2012, with the whole society’s electricity consumption rising in August from the previous month and the electricity consumption for urban and rural residents grew rapidly. Hydropower generation in the first half of the year, the thermal power generation capacity growth, but since July the national hydropower generating capacity for two consecutive months of negative growth year on year, most of the hydropower generating capacity of hydropower negative growth, leaving the market for thermal power, coupled with high temperature hot load Surged, the national thermal power generating capacity growth rate of nearly 20%; hydropower, thermal power, nuclear power equipment utilization hours down over the same period the previous year, wind power generation increased rapidly, equipment utilization hours increased significantly year on year. The investment in power grid increased rapidly year on year and the power investment achieved positive growth year-on-year, but the thermal power and nuclear power investment dropped greatly year on year. Infrastructure installed capacity of new generating capacity over the previous year increased by more than three percent, the new scale of hydropower hit a new high over the same period, the scale of thermal power under construction substantially reduced year on year, but
