Metrica provides Telecommunication Assessments for wind farms across the UK
Our assessments identify, evaluate, and mitigate potential impacts on existing telecommunications infrastructure, ensuring compliance with planning requirements and reducing project risks
What is a Telecommunications Impact Assessment?
A Telecommunications Impact Assessment (also known as a Telecoms Impact Assessment) is a technical study that evaluates whether a proposed development – most commonly wind turbines – could affect existing communications systems.
Understanding telecommunications infrastructure
Telecommunications systems include:
- Fixed wireless links;
- Microwave and radio communications;
- Broadcast and mobile networks;
- Emergency services communication; and
- Radar and navigational systems.
Wind turbines, due to their height, rotor movement, and reflective surfaces, can cause signal obstruction, reflection, or interference. A Telecommunications Impact Assessment identifies these risks and assesses whether mitigation measures are required.
How wind farms can affect communication networks
Turbines can disrupt line-of-sight communications, impact network reliability, and interfere with critical signals. Conducting a Telecoms Assessment ensures these potential impacts are identified early, helping developers avoid objections and delays.
When Are Telecommunications Impact Assessments Required?
Telecommunication Impact Assessments are often required as part of the planning application process for wind energy developments, particularly where:
- Turbines exceed specific dimensions;
- The site is close to critical telecommunications infrastructure;
- Stakeholders such as Ofcom, network operators, emergency services, or aviation authorities have concerns; and
- Local planning authorities request an assessment of telecommunications.
A robust Telecoms Impact Assessment demonstrates that potential impacts on communications networks have been considered and mitigated.
Planning authority requirements
Planning authorities will typically expect wind farm planning applications to include an assessment on the potential impact on existing telecommunications. Telecoms assessments will also include operator consultation responses and evaluate interference risks. Undertaking consultation with relevant stakeholders early prevents unnecessary delays.
Situations where stakeholder consultation is needed
As part of the planning process, stakeholders may request that a Telecoms assessment is undertaken to demonstrate that the wind farm development will not impact existing infrastructure or links. Metrica has extensive experience consulting with stakeholders to confirm the location of telecommunication infrastructure and links, and to discussing setback / buffer distances which may need to be applied.
What Does a Telecommunications Impact Assessment Involve?
Metrica’s telecommunication impact assessments combine technical expertise with planning-focused reporting. Key steps include:
Desk-based review of existing telecommunication infrastructure
- Identification of nearby telecommunications networks;
- Analysis of operator consultation responses; and
- Review of safeguarding constraints.
Technical assessment of potential telecom impacts
- Evaluation of line-of-sight interference;
- Assessment of signal reflection, obstruction, and diffraction; and
- Consideration of turbine height, layout, and rotor movement.
Telecoms stakeholder liaison and consultation
- Communication with network operators when required; and
- Review and interpretation of consultation responses.
Reporting and mitigation recommendations
- Identification of mitigation measures where impacts are predicted; and
- Production of planning-ready telecommunication impact assessment reports to support a planning application.
Metrica’s telecoms assessments are robust, proportionate, and tailored to each project.
