The Hornsea Four Offshore Wind Farm (Amendment) Order 2025

Published: Tue 15th Apr 25

The Hornsea Four Offshore Wind Farm (Amendment) Order 2025 amends the 2023 Order to make non-material changes to bycatch reduction measures.

Specifically, it revises the definition of "the offshore compensation measures" and modifies paragraphs 10-12 of Part 3 of Schedule 16, related to guillemot compensation, by updating consultation processes, predator eradication methods, and notification requirements.

The changes were made following an application under the Infrastructure Planning (Changes to, and Revocation of, Development Consent Orders) Regulations 2011 and are effective from April 14, 2025.

Arguments For

  • Efficiency and Streamlining: The amendments aim to improve the efficiency and clarity of the existing bycatch reduction measures, potentially leading to faster implementation and better results.

  • Environmental Protection: The changes are intended to enhance the protection of marine wildlife, particularly guillemots, by refining the compensation strategy and approval process for mitigation efforts.

  • Compliance with Regulations: The amendment process adheres to the established legal framework for modifying development consent orders, ensuring transparency and accountability.

  • Stakeholder Collaboration: The changes incorporate input from various stakeholders, including Natural England and local authorities, promoting cooperation and ensuring a more comprehensive and effective approach.

Arguments Against

  • Unintended Consequences: The specific amendments could have unforeseen consequences on other aspects of the wind farm's operation or the wider marine ecosystem.

  • Implementation Challenges: Applying the new stipulations might present practical difficulties for the project developers, leading to delays or increased costs.

  • Potential for Litigation: Any alteration to the original order could potentially invite legal challenges from affected parties if deemed insufficient.

  • Resource Allocation: The time and resources expended on amending the order could have been directed to other aspects of project management or environmental monitoring.
