Planning history

“Relevant Planning History 4.1. The proposed development was the subject of formal pre-application consultation submitted in May 2024 (Reference P/24/0006/PAN).”

Officer report

What officers recommended

Officers recommended permission because the proposal supported renewable energy, complied with the development plan and could be controlled by conditions.

“In terms of the adopted South Lanarkshire Local Development Plan 2, Policy 18: Renewable Energy states that applications for renewable energy infrastructure developments will be supported subject to an assessment against the relevant criteria and requirements set out in the Assessment Checklist for Renewable Energy Proposals found in Policy RE1 Renewable Energy.”

“Conclusion In conclusion, a full assessment of the proposals against the development plan (consisting of both NPF4 and South Lanarkshire Local Development Plan 2) has been carried out. NPF4 Policy 1 directs decision makers to give significant weight to the global emergency crisis. Furthermore, Policy 11 states that proposals for renewable energy that contribute to renewable energy generation targets should be supported.”
