keep The Infrastructure Planning (Onshore Wind and Solar Generation) Order 2025
This Order amends the Planning Act 2008 to increase the Nationally Significant Infrastructure Project (NSIP) threshold for onshore wind and solar generating stations from 50MW to 100MW, while also creating a new category bringing non-wind/solar stations over 50MW under the NSIP regime. It includes extensive transitional provisions grandfathering existing applications and decisions under the prior 50MW threshold. The Order extends to England and Wales and comes into force on 31st December 2025.
While Britain should pursue far more ambitious planning reform, this Order provides modest deregulatory benefit by raising the NSIP consent threshold for wind and solar from 50MW to 100MW, reducing regulatory burden for smaller renewable projects. The transitional provisions prevent exploitation of the threshold change by locking in existing applications under prior rules. Britons would be worse off without this Order as it would leave in place the more restrictive 50MW threshold, requiring more renewable projects to undergo the burdensome NSIP process—a process that has demonstrably delayed and increased costs for clean energy development. The Order takes a pragmatic approach within the existing framework rather than creating new restrictions.
