Spain's renewable energy sector is one of Europe's most active for M&A. This guide analyses the valuation of solar and wind assets, the impact of PPAs, the regulatory framework and the sale process for companies in the sector.
Spain is one of Europe’s largest renewable energy markets. With over 70 GW of installed renewable capacity and a development pipeline exceeding 150 GW, the sector generates an M&A transaction volume that places it among the most active on the continent.
For the entrepreneur or investor holding renewable assets — whether operating plants, development-stage projects or sector services companies — the sale opportunities are broad, but the complexity of the valuation and process requires deep understanding of market dynamics.
Exceptional solar resource. Spain has one of the best solar irradiation levels in Europe, translating into superior capacity factors and more competitive generation costs. For international investors, the energy yield of Spanish assets is a clear differentiator.
Binding climate targets. The PNIEC (National Integrated Energy and Climate Plan) sets ambitious renewable capacity targets requiring massive investment. These targets provide long-term visibility for the sector.
Growing corporate demand. Large Spanish companies and multinationals with a Spanish presence are actively seeking PPAs to meet their decarbonisation commitments. That demand supports long-term green electricity prices.
ESG as a catalyst. ESG investing has directed vast amounts of capital towards renewables. Funds with ESG mandates are required to invest in green assets, broadening the buyer base and pushing multiples upward.
Market maturity. Spain has a complete ecosystem: developers, EPC contractors, operators, financiers, and specialist legal and technical advisers. That maturity facilitates transactions and reduces execution risk.
Utilities and major energy companies. Electric utilities acquire renewable assets for their generation portfolio. They seek operating plants of significant size (>50 MW) with long-term energy sale contracts.
Infrastructure funds. They seek stabilised assets with predictable long-term cash flow. They accept lower IRRs than other investors in exchange for stability and duration. They are the natural buyers of operating plant portfolios with PPAs.
IPPs (Independent Power Producers). Independent producers growing through acquisition of assets and development portfolios. They seek both operating plants and advanced-stage development projects.
Private equity funds. They invest in renewable development platforms, seeking value creation by advancing projects from early stages to ready-to-build or COD (Commercial Operation Date).
Corporate investors. Non-energy companies investing in renewable assets for self-consumption or as a financial investment with an ESG component.
The valuation of a renewable company depends fundamentally on the maturity of its assets.
They are valued using discounted cash flow (DCF) analysis, considering:
Resulting EBITDA multiples vary by technology and contracting profile:
| Asset type | EBITDA multiple |
|---|---|
| Solar with long-term PPA | 9 – 12x |
| Solar merchant (no PPA) | 6 – 9x |
| Wind with PPA | 8 – 11x |
| Wind merchant | 5.5 – 8.5x |
| Assets with regulated remuneration | 10 – 14x |
They are valued per MW of capacity, with premiums for advancement status:
| Development stage | Indicative value (EUR/MW) |
|---|---|
| Land secured + feasibility study | 10,000 – 30,000 |
| Environmental permit obtained | 30,000 – 60,000 |
| Grid access and connection granted | 60,000 – 100,000 |
| Ready to build (RTB) | 100,000 – 180,000 |
O&M, engineering, consulting and installation companies are valued using EBITDA multiples similar to other services sectors (5-8x), with premiums for long-term contracts and a diversified client portfolio.
Technical documentation is especially important in the renewable sector:
Due diligence in the renewable sector is technically demanding:
Technical. Independent resource assessment, actual vs. forecast performance, equipment condition, panel or turbine degradation, incident history.
Legal-regulatory. Current permits and licences, applicable remuneration regime, grid connection conditions, land lease terms, easements.
Environmental. Compliance with the environmental impact declaration, compensatory measures, risks of impact on protected areas.
Financial. Project finance debt structure, loan conditions, covenants, reserve accounts, cash waterfall.
Contractual. PPAs, O&M contracts, manufacturer warranties, insurance, spare parts supply agreements.
Regulatory risk. Spain has a track record of regulatory changes that have affected the sector (moratoria, retroactive cuts, remuneration regime changes). Professional buyers incorporate a regulatory risk premium into their valuation.
Electricity price risk. Assets without PPAs are exposed to electricity market volatility. Long-term price curves are a matter of debate between buyers and sellers.
Administrative complexity. Renewable project permitting in Spain involves multiple administrations (national, regional, municipal) and can take several years. Administrative delays are a real risk that affects development-project valuations.
Curtailment and grid congestion. In some areas, the electricity grid lacks sufficient capacity to evacuate all renewable production. Curtailment risk reduces effective production and asset value.
At Blue Mountain we see renewable energy as a strategic long-term sector. Our patient capital approach is well-suited to a sector where assets generate value over 25-30 years and where a long-term perspective is a competitive advantage.
We are interested in both development platforms with qualified technical teams and operating asset portfolios with stable cash flows. We particularly value companies that have built solid relationships with local administrations, have a diversified project pipeline and operate with rigorous technical and environmental standards.
If you own renewable assets or a sector company and are considering sale or partnership options, contact us for a confidential conversation.
