Turkey has 12,000 MW installed wind energy; Balikesir Bares, Manisa Soma and Izmir Cesme WPPs lead. A modern 4-6 MW turbine has a 100 m nacelle holding 400 L hydraulic + 3 t gearbox oil. NFPA 850 requires nacelle FM-200 or water mist, tower egress, dry-type transformer and lightning protection.
Nacelle Hazard
- Hydraulic oil: 400 L Class IIIB
- Gearbox oil: 2-3 t ISO 320
- Electrical: 690 V -> 34.5 kV
- Transformer oil: Mineral or dry
- Composite blade: Fiberglass epoxy
Suppression
- FM-200 (HFC-227ea): Nacelle cleaning
- Water mist: High pressure 70 bar
- Aerosol: Condensed K
- Detection: Multi-sensor smoke + heat
- Auto-shutdown: Turbine stop
Tower Egress
- Ladder: 100 m vertical
- Rescue kit: Descender device
- Platform: Rest every 9 m
- Top escape: Nacelle side hatch
- GWO BST: Mandatory training
Lightning Protection
- IEC 61400-24: Blade-tip receptor
- Down conductor: To blade root
- LPS: Class I
- Rainy period: Rising risk
- Annual: 3-5 strikes/turbine
Turkey WPPs
- Balikesir Bares: 142 MW
- Soma WPP: 240 MW
- Manisa Dagpazari: 165 MW
- 2019 Cesme fire: Nacelle
- 2021 Bandirma: Lightning strike
