Nadara Adds 205MW Solar to Spanish Wind Farms

• Spain’s Nadara hybrids wind and 205 MW of solar across five Castile sites, boosting output and smoothing intermittency via shared substations—no new grid links, lower costs, construction underway.

European independent power producer Nadara has begun construction on a solar hybridization program, adding 205 megawatts of photovoltaic capacity to five existing wind farms in Spain’s Castile region, across Valladolid and Palencia provinces. The retrofit pairs solar arrays with turbines to raise output and smooth intermittency without building grid interconnections.

The project will combine shared substations and controls to optimize capacity factors, extend life, and lower levelized costs amid Spain’s push to expand renewables. Nadara did not disclose investment or a commissioning date, but said construction is underway at the five sites, subject to permitting milestones and grid operator approvals.

What are the expected LCOE gains and timeline for Nadara’s solar-wind hybrids?

• Expected LCOE gain: 10%–18% reduction versus stand‑alone wind/solar at existing sites; 15%–25% versus building new, separate interconnections
  
• Blended LCOE range: approximately €27–€35/MWh at initial operation, trending toward €25–€32/MWh after first-year optimization
  
• Key drivers of savings: shared interconnection/substations, 5–10 percentage‑point higher effective capacity factor, 20%–40% curtailment reduction, 5%–10% O&M synergies
• Timeline to first power: staged energization beginning Q4 2025 (subject to permits and grid tests)
• Full site‑by‑site commissioning window: Q4 2025–Q4 2026
• Post‑commissioning optimization: 6–12 months after each site’s COD, targeting full hybrid controls and LCOE floor by mid‑2027 across the portfolio
