英国新能源并网积压问题治理及启示
Zhong Guo Dian Li Bao· 2025-07-02 07:14
Core Insights - The UK is facing a significant backlog in renewable energy projects awaiting grid connection, with over 770 GW of projects pending, far exceeding the current installed capacity of around 60 GW [1] - The average waiting time for renewable energy projects to connect to the grid has surpassed 6 years, with about 30% of installations facing delays of over 10 years [1] - The backlog is hindering the UK's energy transition, with the annual growth rate of renewable energy generation dropping to 4.45% over the past three years, below the medium to long-term target of over 20% [1] Grid Connection Issues - The core issue lies in the rigid grid connection mechanism and outdated grid investment planning [2] - The management of grid connection is characterized by a "first-come, first-served" principle, allowing developers to queue regardless of project feasibility, leading to speculative applications and a high number of "zombie projects" [3] - Regulatory mechanisms have resulted in insufficient grid investment, exacerbating the backlog problem [4] Reform Initiatives - The UK has introduced the "TMO4+" reform to address the backlog and inefficiencies in planning, focusing on a demand-driven approach and verifying project maturity [6] - A dual-threshold admission standard will be implemented, replacing the traditional queuing system with a "ready to connect" mechanism, which requires projects to demonstrate feasibility and alignment with the UK's 2030 carbon peak planning [6] - The reform is expected to eliminate approximately 68% of "zombie projects," freeing up resources for viable projects [6] Dynamic Queue Optimization - The reform includes a "process elimination system" to remove overdue projects from the queue, thereby releasing grid capacity [7] - A "flexible replacement" rule will allow mature projects to fill capacity gaps quickly, and regional capacity rebalancing will address structural imbalances in energy distribution [7] - A streamlined approval process will be established, integrating various departmental procedures into a "one-stop" platform to reduce administrative time costs [7] Investment in Grid Infrastructure - The UK plans to invest £35 billion in the largest grid upgrade project globally from 2026 to 2031, focusing on enhancing renewable energy transmission and grid flexibility [9] - Over £11 billion will be allocated for maintenance and upgrades of existing transmission networks, while approximately £24 billion will support strategic transmission investments [9] - The upgrade will involve enhancing around 3,500 km of overhead lines to nearly double transmission capacity and deploying innovative technologies [9] Lessons for Other Markets - Other markets, such as China, can learn from the UK's experience by ensuring adequate infrastructure investment and optimizing priority mechanisms and approval efficiency [11] - Emphasizing "proactive grid investment" principles and enhancing the capacity of transmission networks in renewable-rich areas are crucial [11] - A unified management approach can prevent fragmented development and ensure coordinated resource allocation [12] - Prioritizing mature projects and implementing a dynamic scoring system for project prioritization can help avoid resource misallocation [13]
