近几年，随着国家宏观经济政策的调整，作为老工业基地的天津市受到了较大影响。一些高耗能企业、技术含量低的企业被迫停产，致使天津市电力公司出现了售电量增幅下降、电网峰谷差加大、负荷率持续下滑的困难局面。发电机利用小时逐年降低，负荷率管理难度越来越大，严重影响 In recent years, with the adjustment of the country’s macroeconomic policies, Tianjin, an old industrial base, has been greatly affected. Some high-energy-consuming enterprises and enterprises with low technological content were forced to suspend production, resulting in the Tianjin Power Company’s difficulties in reducing the growth rate of power sales, increasing the peak-to-valley gap of the power grid, and the continuous decline in the load factor. The utilization hours of generators have been reduced year by year, and the management of load rates has become more and more difficult.
