京津冀农村“煤改电”运行情况分析

Performance analysis of rural “coal to electricity” in Beijing-Tianjin-Hebei

针对分布更广、难度更大的农村散煤治理,总结分析京津冀已有实践,着重对比各类"煤改电"建设运行成本、使用情况以及对电网的影响和对补贴政策依赖。分析得出,农村居民既有建筑电采暖到户电价0.1元/k Wh,才能保持燃煤取暖费用水平。农村分散"煤改电"方式使用率低、后期运维困难。在集中居住区,蓄热集中改造方式有利于实现精准投资、提升电网运行效率。最后,提出精准补贴建立全社会分摊机制。

Aiming at the more widely distributed and more difficult rural coal treatment, a summary of the existing practices of Beijing-Tianjin-Hebei has been put in place, focusing on the comparison of various coal-to-electricity construction operating costs,their use, the impact on the power grid and the dependence on subsidy policies. According to the analysis, when the household electricity price of electric heating for the existing buildings of the rural residents reaches 0.1 yuan/kWh, the cost of heating coal-fired heating can be maintained. The dispersal of ＂coal to electricity＂ in rural areas has a low utilization rate and is difficult to operate and maintain in the later period. In centralized residential areas, the centralized heat storage reconstruction method is beneficial to achieve accurate investment and improve grid operation efficiency.Finally, a precise subsidy is proposed to establish a social apportionment mechanism.
