RTB Solar PV Asset Valuations – Southern Europe
Critical Market Intelligence for Renewable Energy Professionals
The Southern European solar PV market in H2 2024 demonstrated exceptional resilience amid broader European valuation pressures, revealing a region where superior solar resources and streamlined regulatory frameworks continue to support investor confidence. However, beneath this regional strength lay significant country-specific divergences, from Spain's remarkable valuation stability to Portugal's dramatic buyer expectation adjustments - creating a complex landscape requiring sophisticated market analysis.
This analysis provides definitive benchmarking data for RTB solar PV asset valuations across Greece, Italy, Portugal, and Spain - markets representing over 68,000 MWp of operational solar capacity where billions of euros in investment decisions depend on precise valuation intelligence.

- Greece: -5.2% (modest stability)
- Italy: -5.5% (moderate adjustment)
- Portugal: -38.1% (dramatic correction)
Critical Insight: Portugal's dramatic adjustment reflects acute cannibalization concerns in the Iberian market, while Spain's stability suggests better market structure adaptation to these same pressures.

Connection Timelines Influencing Valuation Differentials:
- Greece: 2-3 years (mainland), longer for islands (supporting higher valuations)
- Portugal: 2-3 years (relatively manageable despite market pressures)
- Spain: 2-4 years (increasing congestion in solar-dense southern regions)
- Italy: 3-5 years (structural north-south transmission constraints)
Correlation: Greece's shorter connection timelines support its premium valuations, while Italy's extended delays contribute to wider buyer-seller gaps despite strong fundamentals.
Solar Cannibalization Impact: The Revenue Threat
- Spain & Portugal: Severe Iberian market cannibalization driving different valuation responses
- Italy: Growing southern region cannibalization with north-south constraints providing partial insulation
- Greece: Early-stage cannibalization emerging but contained by market structure
Valuation Impact: Portugal's 38.1% buyer expectation decline directly correlates with acute cannibalization concerns, while Spain's adaptation strategies (hybridization, strategic siting) maintain valuation stability.
BESS Deployment Reveals Anti-Cannibalization Strategies:
- Spain: 7,000 MW total BESS (6,000 MW development + 1,000 MW operational)
- Italy: 6,200 MW total BESS (5,000 MW development + 1,200 MW operational)
- Portugal: 2,500 MW total BESS (2,000 MW development + 500 MW operational)
- Greece: 1,200 MW total BESS (1,000 MW development + 200 MW operational)
Strategic Insight: Portugal's BESS pipeline represents 40% of its solar development - the highest ratio in Southern Europe - directly responding to acute cannibalization pressures. Spain's lower BESS ratio (30%) suggests more sophisticated market adaptation strategies.
