Selecting the right location for a wind farm is one of the most critical steps in the development process. A well-chosen site maximizes energy production, minimizes environmental and community impact, and ensures financial viability. This phase involves assessing wind resources, land suitability, grid access, and regulatory considerations to determine whether a site is viable for wind energy development.

📂 Key Factors in Site Selection

1. Wind Resource Assessment

The energy output of a wind farm depends on the speed, direction, and consistency of wind at a site. Developers assess wind resources using:

• Historical Weather Data – Long-term meteorological records from sources like the Met Office.
• GIS Wind Mapping Tools – National wind atlases and spatial datasets.
• On-Site Measurements – Deploying LiDAR (Light Detection and Ranging) or meteorological masts for real-world wind speed data.

Sites with higher and more consistent wind speeds are preferred, as energy output increases exponentially with wind speed.

2. Land Ownership & Lease Agreements

Wind farms require long-term access to land, typically through lease agreements between developers and landowners. Key considerations include:

• Land Availability – Ensuring sufficient space for turbine layout, infrastructure, and access roads.
• Land Use Compatibility – Assessing how turbines integrate with farming, forestry, or other existing land uses.
• Ownership & Legal Constraints – Understanding property boundaries, rights of way, and any existing land agreements.

In most cases, landowners receive annual payments for hosting turbines, which provide a stable additional income.

3. Grid Connection Feasibility

For a wind farm to deliver power to consumers, it must connect to the electricity grid. The feasibility of grid access depends on:

• Proximity to Existing Grid Infrastructure – Distance to substations, overhead power lines, and connection points.
• Network Capacity – Whether the local grid can accommodate additional electricity generation.
• Grid Application & Costs – The process of applying for a connection with Distribution Network Operators (DNOs) and estimating costs for infrastructure upgrades.

Grid constraints can significantly impact project feasibility and costs, making early engagement with DNOs essential.

4. Planning & Environmental Considerations

Before advancing a site, developers review local planning policies and environmental constraints to ensure that the project is likely to receive approval. Factors include:

• Local & National Planning Policy – Identifying areas designated for wind development.
• Land Designations & Protected Areas – Avoiding National Parks, AONBs (Areas of Outstanding Natural Beauty), SSSIs (Sites of Special Scientific Interest), and heritage sites.
• Aviation & Radar Restrictions – Ensuring compliance with air traffic control and military radar requirements.

5. Financial & Technical Viability

A viable wind farm must be economically sustainable. Early feasibility studies include:

• Energy Yield Projections – Estimating how much electricity the site can generate annually.
• Development Costs – Assessing expenses related to land leases, permitting, grid connection, and construction.
• Revenue Models – Evaluating potential income from government incentives, Contracts for Difference (CfD), and Power Purchase Agreements (PPAs).

Developers use financial modelling to determine whether a site is commercially viable before proceeding with further studies.

📌 Timeline for Site Selection & Feasibility

Phase	Key Activities	Typical Duration
Initial Site Screening	GIS mapping, wind resource analysis, landowner outreach	3–6 months
Wind Monitoring	LiDAR or meteorological mast deployment	12–24 months
Grid Feasibility Study	DNO engagement, capacity checks, cost estimates	3–9 months
Planning Pre-Screening	Reviewing land constraints, planning policies, and permitting risks	3–6 months
Financial Pre-Feasibility	Preliminary cost analysis, revenue modelling, risk assessment	3–6 months

A site that passes all feasibility assessments moves to the Development & Permitting phase, where detailed technical and environmental studies begin.
