Wind Farms in Wales: Over 100 Sites Powering Renewable Leadership

Wales hosts over 100 operational wind farms with 2,000+ MW total installed capacity—making it a UK leader in wind energy per capita and land area.

Flagship Project: Pen y Cymoedd

• Location: Rhondda Cynon Taf / Neath Port Talbot (South Wales valleys)
• Capacity: 228 MW (76 × 3 MW turbines)
• Operator: Vattenfall
• Annual output: ~600 GWh — powers ~180,000 homes
• Community benefit: £1.8M/year fund (habitat restoration, cycling trails, local grants)
• Habitat restoration: 1,500 hectares peatland/bog — carbon sequestration co-benefit

Other Major Wind Farms

Onshore vs. Offshore Balance

• Onshore: ~1,200 MW — mature, community-contested but cheaper
• Offshore: ~800+ MW — growing fast, higher capacity factors, less visual impact
• Floating offshore: Pilot projects (Pembrokeshire) — next frontier for deep Celtic Sea

Policy Context

• Welsh Government target: 70% electricity from renewables by 2030 (currently ~55%)
• Future Wales Plan: Identifies Strategic Search Areas for new wind
• Community ownership: Encouraged via Ynni Cymru (Wales Energy Service)
• Planning: Developments of Significance (>10 MW) decided by Welsh Ministers

Challenges

• Grid capacity constraints (north-south transmission bottleneck)
• Cumulative landscape impact in valleys
• Peatland carbon payback debates
• Supply chain / skills gaps

Wales' wind resource — consistent westerlies off Atlantic, elevated terrain — is among Europe's best. The 100+ farms represent both achievement and foundation for the next doubling.
