Financial Modeling

With our cash-flow simulations and optimization algorithms we enable systematically evaluating a variety of financial planning problems.

Risk Quantification

With our innovative risk quantification frameworks and analytical tools we enable rethinking and shadowing risk to create future opportunities.

Software Engineering

We provide integrated software solutions for renewable energy stakeholders to cope with new challenges in a changing market.

Data Analytics

We feature professional, software-based consulting services enabling data-driven decision making for renewable energy stakeholders.

Our Products

We combine methods from meteorology and finance to enable automated economic viability and risk analyses for renewable energy projects based on in-depth estimations of site-specific wind and solar resources.


A geographic information system processing extensive topographical and meteorological data into an integrated system of spatial interpolation, height extrapolation, statistical downscaling and spatial planning methods. REGIS enables analyzing site-specific resource and spatial potentials for wind and solar farms by estimating wind, solar and power generation time series and statistics as well as spatial planning potentials.


A financial decision support system integrating an innovative financial modeling approach with an extensive risk quantification framework by means of Monte Carlo simulations and optimization algorithms. IRIS enables analyzing and optimizing profitability and bankability of wind and solar farms under consideration of risk and uncertainty and provides professional decision support to a variety of financial planning problems.
