More years, more papers, more turbines

Published: 11 Aug 2017

For the past few months, we have been running a closed beta test, offering four years of data.  Thanks to all our users that took part in testing!  Since this ran smoothly, we are happy to announce that as of today, the Ninja is able to serve 17 years of weather and renewables data – from 2000 through to 2016.

This expanded data set is now available to all registered users.

You can now choose which year to download through the web interface.  If you’re using the API, you can still select a more precise range of dates. In either case, requests can be for a maximum of one year at a time.   If you want to download longer timespans, you will need to run an individual simulation for each year – we found the server simply cannot cope with processing >100 GB of weather data in a single request!

We hope this enables you to move forwards with answering new and interesting research questions!

Speaking of research, we have been collaborating with two international teams on studies using the Renewables.ninja. With Fabrizio Fattori and Norma Anglani of Università degli Studi di Pavia (Italy) we published a paper showing that high concentrations of solar PV will have significant effects on the power system of northern Italy, and how electricity storage can help to reduce peak demand, ramping rates and over-generation.

F. Fattori, N. Anglani, I. Staffell and S. Pfenninger. High solar photovoltaic penetration in the absence of substantial wind capacity: Storage requirements and effects on capacity adequacy. Energy (2017). doi: 10.1016/j.energy.2017.07.007

Then with Christian Grams, now of Karlsruhe Institute of Technology (Germany), Remo Beerli and Heini Wernli (ETH Zürich) we have published a paper in Nature Climate Change showing how a new understanding of continental-scale weather regimes and greater cooperation between countries could dramatically smooth the output of wind farms across Europe:

C.M. Grams, R. Beerli, S. Pfenninger, I. Staffell and H. Wernli, 2017. Balancing Europe’s wind power output through spatial deployment informed by weather regimes. Nature Climate Change (2017), 7, 557–562. doi: 10.1038/nclimate3338

Finally, we have upgraded the wind model to include 121 wind turbine models.  You can type into the textbox on the web interface to search for available models.  We have selected the 10 most widely used models (both in existing and planned wind farms) to sit at the top of this box as the default input.

Here are some of the most widely used turbine models in our database.  Highlighted rows show the turbine models that appear at the top of the UI selector.
