Energy Yield Assessments

We provide wind resource and energy yield assessments throughout all stages of project development, supporting wind, solar and BESS projects as well as hybrid solutions. Our evaluations can either be based on collected measurement data or on estimates, when measurements are not available.

Our expertise covers wind resource assessment, solar resource and irradiance assessment, production modelling and energy yield assessment.

At Etha, we take pride in producing accurate, reliable and consistent results in accordance with international best practices. We continuously validate our calculation results and have detailed understanding of calculation uncertainties, providing realistic results that support sound project and investment decisions.

For early-stage wind power analysis, we have developed our own methodology using official production data from Finnish wind farms to provide reliable wind estimates even when on-site measurements are not yet available.
