-- 美国可再生能源协会(Renewable America)的战略家们周二在一份白皮书中指出,加州现有的配电网络可以容纳5.4吉瓦的社区规模太阳能和储能系统,在未来二十年内为加州电力用户节省约65亿美元。 报告称,所谓的“中程”项目,即在配电层互联的太阳能和储能资产,与大型公用事业规模的开发项目相比,能够更快、更经济地实现脱碳,同时缓解加州紧张的电网压力。 美国可再生能源协会估计,充分利用现有配电容量还可以减少46亿美元的资源充足性成本,并避免约20亿美元的输电升级支出。 分析表明,与通常需要五到十年才能投入运营的公用事业规模项目不同,社区规模的系统通常可以在两到三年内部署完成。随着电力需求的增长和电网限制的加剧,这一时间节点至关重要。 “加州一直专注于‘第一英里’(大型公用事业规模的可再生能源)和‘最后一英里’(屋顶太阳能),但真正的机遇在于‘中间英里’,”Pathfinder Communications 的负责人兼该报告的作者 Peter Asmus 表示,“基础设施已经到位。” 社区选择聚合商 (CCA) 目前服务于加州超过三分之一的电力用户,被认为是关键的部署渠道。 报告指出,CCA 有望加速分布式能源的建设,但监管和结构性障碍仍在阻碍进展。 近年来,加州为实现其清洁电力目标而扩大了可再生能源的部署,但仍面临着输电瓶颈、审批延误和需求增长等持续的制约因素。
