Spain’s energy sector is one of the most capital-intensive in the economy. With just over 10,729 active companies and nearly 40,492 workers registered with Social Security, it generates aggregate revenue of €136.9 billion — the highest per-company figure of any sector analysed — with an average gross margin of 19.8%. This market structure, dominated by large utilities and complemented by a growing network of independent renewable developers, reflects the nature of the energy business: massive assets, long-term contracts and a value chain that concentrates returns in few hands. Spain is a world leader in solar photovoltaic and wind power generation, and its National Integrated Energy and Climate Plan (PNIEC) sets a target of 74% renewable generation by 2030.
The sector’s historical regulatory volatility — with retrospective changes to remuneration regimes that triggered intense international arbitration — has taught investors that regulatory risk management is not optional. Investment decisions in Spanish energy assets require rigorous legal and tax due diligence, careful structuring of the investment vehicle and continuous monitoring of sector regulation. The current context, with the impetus of NextGenerationEU funds and the pressure of the decarbonisation agenda, is generating an extraordinary flow of opportunities that demand advisors capable of moving with equal agility across the fiscal, legal and financial domains.
At BMC we advise renewable energy developers, utilities, infrastructure funds and grid operators on the tax and legal structuring of their investments in Spain. Our services cover due diligence on energy assets, SPV and project finance structuring, PPA contract negotiation, CNMC regulatory framework compliance and tax planning for projects throughout their lifecycle. We also manage the procurement of European and national grants for green hydrogen, energy storage and energy efficiency projects.
The ESG agenda is increasingly relevant for the sector. We support clients in designing sustainability strategies, issuing green bonds and sustainability-linked loans with KPI-based covenants, reporting under CSRD/GRI standards and integrating EU Taxonomy criteria into investment decision-making. Our integrated approach — combining financial, tax and legal advisory with deep sector knowledge — enables us to accompany clients from opportunity identification through to the disposal of mature assets.

Key Sector Terms
Accelerated Depreciation in Spain (Amortización Fiscal Acelerada)
Accelerated depreciation (amortización fiscal acelerada) in Spain allows companies to deduct a higher proportion of an asset's cost in the early years of its useful life for Corporate Tax purposes, reducing taxable income sooner than straight-line accounting depreciation would permit. Spain offers both statutory accelerated tables and specific regimes for SMEs, newly hired personnel, and R&D assets.
EU AI Act
The EU Artificial Intelligence Act (Regulation EU 2024/1689) is the world's first comprehensive legal framework for artificial intelligence. It classifies AI systems by risk level, imposes obligations on developers, deployers, and importers, and establishes penalties of up to €35 million or 7% of global turnover for the most serious violations. It entered into force in August 2024 with phased compliance deadlines through 2027.

Spain has a well-developed framework for alternative dispute resolution (ADR). Arbitration is governed by Ley 60/2003 de Arbitraje (based on the UNCITRAL Model Law) and provides a binding, private process with enforceable awards. Mediation in civil and commercial matters is regulated by Ley 5/2012. Spain is a signatory to the New York Convention (1958), enabling international enforcement of Spanish arbitral awards in 170+ countries.
