heartbeat of renewables


New call-to-action

We’re advancing machine learning-based forecasting methods for the energy market and offer our expertise to develop targeted software. Our approach leverages intelligent and adaptive algorithms.

Accurate yield forecasts ensure that renewable energies can be rolled out on the market effectively and sustainably – both for the industry and society.

We implement a holistic strategy and apply our machine learning know-how to related topics to inspire the market with our specialized products.

4cast – looking ahead to the future

Our mission:
Absolute precision

Faster. Better. Weather.

Typical weather reports are very general and ignore decisive micro factors. In contrast, 4cast compiles an individual set of characteristics for every wind and solar power plant, taking into account the terrain, surface conditions, vegetation, or neighboring structures of a park. In close collaboration with our contractual partners, we can create solutions and services that are tailored to the relevant market. We focus on intraday, day-ahead, and long-term forecasts covering up to four days in the future for wind and solar power stations. Depending on requirements, the forecasts can be applied to entire parks or single plants.

Save time with our digital wind assessment (DWA)

Preparing wind assessment reports can be complex and time-consuming. The assessor has to conduct on-site inspections, comply with a range of formalities, potentially obtain additional expert reports, and put the entire process in order. 4cast has therefore made it its mission to reduce this process to a fraction of the time that it usually takes. Our digital wind assessment (DWA) structures tasks from start to finish and in one place. Everything is digitalized to the greatest possible extent. Here too, we draw on our experience in the energy sector and the areas of machine learning and complex algorithms to provide you with a tailored wind assessment report that you can use right away.
