Stefan Pfenninger simulating PV and wind power plants

Together with Iain Staffell, I published two papers, available today, using reanalysis and satellite data to simulate PV and wind power plants across Europe (references at the bottom of this post). Alongside these two publications, we built a large database of measured power output data to validate the simulations and perform bias corrections. This now allows us to accurately model hypothetical European wind and PV power output over several decades, investigating issues like the impact of increasing PV deployment on net power demand:

There’s an Imperial College London story on both papers and an ETH Zürich news story on the wind paper.

To make the simulations available for other researchers, the platform I created and developed together with Iain Staffell alongside these two papers allows users to run simulations of the hourly power output from wind and solar power plants located anywhere in the world: Screenshot screenshot

Data from are free to use under the Creative Commons BY-NC license. The papers are both open access and fully available online. We hope to reduce parallel efforts in creating and validating such simulations, and are looking forward to seeing other people make use of our data!
