英国电网平衡成本创历史新高，每天接近5000万英镑

英国电网平衡成本周三飙升至近5000万英镑的纪录高位1。这一费用的激增源于电力传输基础设施瓶颈，导致国家电力系统运营商被迫关闭约9吉瓦的风电和水电产能1。为补偿这些被关闭的可再生能源发电，运营商不得不启动燃气电厂并从欧洲增加电力进口1。单个半小时周期的平衡成本曾达到160万英镑1。

这一问题的根本原因在于英国电网基础设施升级滞后。据LCP Delta电力交易主管Shivam Malhotra分析，"系统总体电力供应并不紧张，这是老生常谈的基础设施不足问题，导致大量风电场被迫关闭"1。英国计划投入1500亿英镑进行电网升级，但该工程进度跟不上可再生能源项目的并网速度1。

电网平衡成本持续攀升的规模令人担忧。9月份的总成本达到5.05亿英镑，创单月历史新高1，预计未来一年总成本将达32亿英镑1。被要求停止发电的可再生能源容量足以供电超过800万户家庭1。不过，Neso首席执行官Fintan Slye表示在6月份高温期间"没有用户被断电，频率保持在法定限制内"，但承认"这对系统来说是真正的挑战时期"1。

Great Britain's power grid balancing costs reached a historic peak of £47.9 million on Wednesday, driven by transmission infrastructure bottlenecks that forced renewable energy generators offline 1. The National Grid operator was compelled to shut down approximately 9 gigawatts of wind and hydroelectric capacity, subsequently activating gas-fired power plants and importing electricity from Europe to maintain system stability 1. In a single half-hour trading period, balancing costs hit £1.6 million 1, underscoring the severity of the strain on the system.

The financial burden reflects an accelerating crisis in Britain's energy infrastructure. September 2024 recorded the highest monthly balancing costs on record at £505 million, with projections indicating total costs of £3.2 billion for the coming year 1. The underlying issue stems from a £150 billion grid upgrade programme that has failed to keep pace with the rapid deployment of renewable energy projects 1. Shivam Malhotra, head of power trading at LCP Delta, characterized the situation as a classic infrastructure deficit, stating: "The system's overall power supply is not tight. This is the old story of inadequate infrastructure resulting in numerous wind farms being forced to shut down" 1. Fintan Slye, chief executive of the National Electricity Security Operator (Neso), acknowledged that this represented "a genuinely challenging period for the system" 1.
