From a legal standpoint, M&A transactions in the renewable energy sector follow the same basic structures as in other industries: share or asset purchases, mergers by absorption, non-cash contributions, joint ventures, among others. Nevertheless, they do present unique features arising from the regulatory framework specific to power generation, energy planning, remuneration schemes, administrative processing of projects, and public intervention, which is a hallmark of the sector.

One of the first issues to be addressed in such transactions is the identification of the type of asset subject to acquisition. In the case of renewable energy, acquisitions may involve not only operating facilities but also projects under development or portfolios at very early stages. Each scenario presents distinct legal implications. For instance, acquiring an operational plant entail assuming existing contracts, third-party relationships, and typically a track record of regulatory compliance that must be carefully reviewed. Conversely, acquiring a development-stage project involves greater regulatory and technical risk, as well as the need to verify the validity and transferability of administrative permits and authorizations, which are often subject to specific conditions.
In this regard, one of the most critical elements in renewable energy M&A deals is due diligence—the legal, technical, tax, and financial review process that enables in-depth understanding of the target asset or company. From a legal perspective, it is essential to assess the status of licenses and administrative permits, land zoning issues, grid access agreements, power purchase agreements (PPAs), construction and operation contracts, and any contingencies arising from litigation, sanctions, or regulatory non-compliance. For projects under development or construction, the robustness of the project timeline and potential impacts from future regulatory reforms must also be evaluated.
Another key element is the regulation of the electricity sector. In Spain, renewable energy is subject to a specific legal framework that has undergone significant changes in recent years. Companies must consider aspects such as rights of access and connection to the grid, auction mechanisms for obtaining specific remuneration schemes, and the requirements for obtaining construction, commissioning, and operating permits. As a result, transactions are often structured in phases or conditioned on the achievement of administrative milestones—for example, closing the deal or paying part of the price may be contingent on the project obtaining a specific permit or reaching commercial operation.
Public authority oversight is increasingly important in these transactions. In certain cases, deals must be notified to the Spanish National Commission on Markets and Competition (CNMC), particularly where a significant market share in electricity generation is at stake. Furthermore, if the buyer is a non-EU or non-EEA foreign investor, prior authorization from the Council of Ministers may be required. This authorization aims to protect strategic sectors and prevent hostile takeovers or transactions contrary to the public interest. Processing this authorization can take several months and must be factored into the transaction timeline.
Environmental regulation also plays a critical role in the development and operation of renewable energy projects. Acquiring a wind or solar farm implies assuming environmental obligations related to impact assessments, waste management, biodiversity, and compliance with environmental monitoring plans. Regional (autonomous) legislation is also relevant, as the autonomous communities are competent to authorize lower-capacity energy installations. Therefore, a detailed review of the legal framework applicable to each project is required, especially when portfolios include assets located in different regions.

EPC Contracts in the Energy Sector
From a commercial law perspective, careful drafting of the sale and purchase agreement (SPA) is essential. These agreements are typically complex and include various provisions that allocate risk between buyer and seller. Common clauses include representations and warranties, indemnities for contingencies, earn-out provisions (which adjust the price based on future milestones), non-compete covenants, and post-closing cooperation commitments. Many agreements also include price adjustment mechanisms based on net debt or working capital, as well as MAC (material adverse change) clauses that allow contract termination if substantial changes occur in the project or market conditions.
In share deals involving project-owning companies, it is particularly important to verify ownership of the shares, the corporate and accounting status of the company, the validity of powers of attorney, and the existence of shareholders’ agreements that may restrict share transfers. For debt-financed projects, prior consent from lenders is typically required, as financing agreements often include change of control clauses.
Power Purchase Agreements (PPAs) also play a significant role in renewable energy M&A. These long-term contracts, under which a buyer commits to purchasing the energy produced at a fixed price, are vital for ensuring the financial viability of many renewable projects. Legal analysis of PPAs is crucial, as they directly impact project profitability. Moreover, many PPAs include clauses that limit or condition the assignment of the contract in the event of a change of ownership, so buyers must ensure compliance to avoid breaches.
Taxation is another key factor in these transactions. The structure of the deal can have significant tax implications for both buyer and seller, particularly regarding VAT, Transfer Tax, capital gains, and use of tax loss carry forwards. Proper tax planning, along with a risk assessment of past audits or tax contingencies, is essential to avoid unpleasant surprises post-closing.
Lastly, in today’s context of energy transition and digitalization, renewable energy projects increasingly incorporate technological and innovative elements. As a result, many transactions now also involve analysis of intellectual property, cybersecurity, data protection, and the digital management of plants. Investing in renewables is no longer limited to acquiring physical assets; it now includes smart solutions, digital platforms, and innovative business models, all of which require a cross-disciplinary legal assessment.
Conclusion:
Mergers and acquisitions in the renewable energy sector represent an attractive opportunity for both investors and developers. However, the success of these transactions demands a thorough understanding of the applicable legal and regulatory framework, as well as careful, tailored legal planning. Specialized legal advice is, therefore, essential to ensure legal certainty and maximize transaction value in a sector poised to lead Spain’s energy future.
