英国最大的社区太阳能项目 Derril Water 近日被国家能源系统运营商（Neso）下令强制关闭，原因是担心屋顶太阳能发电会导致当地电网出现“热过载”[1]。为防止电压超出安全限制，关键变压器已被切断电源 [1]。该项目预计将在今年 9 月获得允许重新启动 [1]。此次无预警的关停导致约 10,000 名成员面临近 200 万英镑的收入损失 [1]。
该设施已于去年 9 月投入运营，但此前经历了复杂的背景因素：项目由成员筹集的 2,000 万英镑及银行贷款 2,200 万英镑资助；原开发商 Ripple Energy 于 2025 年初破产，随后由 1st Energy 接管 [1]。此外，电网升级延迟也是导致此次关停的背景原因之一 [1]。
Britain's largest community solar project, Derril Water, has been ordered to close following concerns that rooftop solar generation could cause a thermal overload on the local power network [1]. The National Energy System Operator (Neso) issued the directive to switch off critical transformers in order to prevent voltage from exceeding safety limits [1]. This forced shutdown occurred during its first summer of operation after the facility was commissioned last September, though it faced an unexpected closure without prior warning that has raised financial concerns among members [1].
The project is expected to lose approximately £2m in revenue due to the interruption [1]. Funding for Derril Water came from member contributions totaling £20m and bank loans of £22m [1]. The site was originally developed by Ripple Energy, which went into administration at the beginning of 2025 before operations were taken over by 1st Energy [1]. Neso's decision to halt generation stems specifically from fears that high levels of renewable energy production could destabilize the grid infrastructure in this area [1]. The operator anticipates allowing the project to restart later, with a target date set for September [1].
