黑龙江推动“北电南送”跨区交易 交易额增长超60%

2017-08-22 17:45:56   新华网

新华社哈尔滨8月22日电(记者梁冬)记者从国家电网黑龙江电力有限公司了解到,为促进电力资源优化配置,提高新能源的利用率,黑龙江省全力推进“北电南送”跨区交易。

截至8月中旬,这个省南送跨区交易电量达到162.55亿千瓦时,同比增长60.83%,在满足华北地区电力需求的同时,有效缓解了黑龙江省风电等新能源的消纳矛盾。

黑龙江省是国家大型能源基地,其中,风能资源总储量为6.3亿千瓦,技术可开发量5亿千瓦,潜在装机容量7326万千瓦,是全国风能资源最丰富、风资源评价指标最好的省份之一。

近年,随着风电等新能源规模的不断扩大,以火电为主的黑龙江省电网调峰矛盾日益突出,现有的风电消纳能力已远不能满足风电大规模开发的需求,致使风能等新能源优势难以发挥,“弃风”现象时有发生。

为有效缓解弃风现象,黑龙江省全面推进“北电南送”跨区交易,充分利用省内电网发电机组富裕的发电能力,在完成年度计划电量的前提下,开展年度计划外南送电量交易。

电力跨区交易在充分利用新能源的同时,还降低了用户的成本,达到了节能减排的效果。数据显示,在跨区电力交易中,成交大用户直接交易电量82.30亿千瓦时,同比增长153%;平均降低用户购电价格5.01分/千瓦时,减少企业用电成本4.1亿元。按月度开展发电权替代交易30.68亿千瓦时,节约标煤15.50万吨,减少二氧化碳排放40.30万吨,减少二氧化硫0.46万吨,高效节能机组发电利用小时平均增加500小时。
