What Changes Has Ørsted Proposed for Hornsea Project Four?

Ørsted Hornsea Project Four Ltd has applied for a non-material change to its offshore wind farm development in the UK. The adjustments focus on minor technical modifications, such as cable routing optimizations and turbine placement refinements, which do not alter the project’s core environmental or operational scope. These changes aim to enhance efficiency while adhering to existing permits.

How Does the Non-Material Change Process Work?

Non-material changes undergo a streamlined review by the Planning Inspectorate, focusing on whether adjustments fall within the original project’s approved boundaries. Stakeholder consultations and environmental impact reassessments are typically abbreviated, provided the modifications don’t introduce significant new risks. Approval hinges on demonstrating adherence to pre-existing consent conditions.
