The use of Renewable Energies constitutes on the one hand an exercise in responsibility on the part of companies and the public in order to contribute to sustainable development, but in addition savings on power charges as a consequence of the reuse of the energy. Technical-financial feasibility studies and audits of existing facilities are the tools used to make an assessment of installations, prior to and following their introduction.

Analysis of Renewable Energy plants and installations takes in a wide range of studies (the installation of the saving measures described by energy services companies, improvements proposed on the basis of a Technical Due Diligence assessment, upgrading when a new system is introduced, preliminary analysis …) and which can be summarised in two categories:

Technical-financial feasibility studies

Feasibility studies are a useful tool for the analysis of potential risks, to establish the investments which must be made and to disclose the operating costs and the periods of return on the investment for the introduction of certain renewable energy systems and for which real numerical data are not available. They can be applied in Geothermal, Solar, and Wind installations and Neighbourhood Distribution systems.

Audits of existing plants

The purpose of the audits of existing plants is to record consumption and analyse equivalent electrical yields or energy generation in facilities which make use of renewable energies, such as Biomass, Geothermal, Cogeneration, Photovoltaic Solar, Thermal Solar and Wind plants.
