Renewable energies

Mazars counts with a team specialized in the sector to assist companies to efficiently respond to the main challenges to be faced.

Challenges in a constantly changing sector

Governments and institutions’ legislations, the development of new technologies, the scarcity of fossil fuels, and the growing environmental and sustainability concerns, among other factors, are promoting renewable energies, and their weight in in energy production, both at global level and in our countries, is expected to increase significantly. In the current context, marked by an economy in distress and a very complex regulatory environment, the sector players face three large challenges:

  • Financing for business development and new projects
  • Take advantage of international growth and expansion opportunities
  • Innovate in production processes and products


Our experience in the sector

We count with a global, specialized, multidisciplinary team (consultants, risk experts, lawyers and tax advisors, financial advisors…), able to offer a comprehensive advice, adapted to your needs.


Model Audit

In renewable energy projects, the different stakeholders require Model Audit services (we are worldwide leaders in this segment) before carrying out their financial investments. We count with a global team, working from Spain, Canada, US or the UK, able to provide the best response to the specific requirements of debt providers, equity providers and/or the different advisors involved.


We offer our comprehensive advice in the acquisition and sale of renewable energy projects, covering both legal and financial and tax aspects, which allows us to participate in all stages within the operation.

Financial model development

With our own methodology (Corality Financial Modelling), financial model development services can assist your company to improve its development, review or analysis of your project finance models at all levels.


We carry out business, shares and intangible assets’ valuations in different contexts, including, among others, transactions, corporate restructuring operations, financial reporting, taxation and litigations.
