Making complex data accessible
Selecting appropriate sites for onshore wind turbines or solar farms is often complicated and time consuming. Open Site Energy leverages a fully open source approach to renewable site selection so individuals and organisations save time selecting the best sites.
- Open Site Energy ElementsOpen Site Energy embraces a modular, interoperable approach to renewable site selection using a range of industry standards.
- Open Data PortalOpen Site Energy's Open Data Portal manages the complex range of datasets involved in renewable site selection. It runs on CKAN, the world’s leading open source data management system.
- Open Source Data PipelineOpen Site Energy's data pipeline converts complex site constraint definitions into accessible and high quality site selection layers. It runs on Docker, Python and PostGIS and is fully open source on GitHub.
- Open Standards OutputsThe Open Site Energy toolkit outputs data layers in a range of industry-standard GIS formats including GeoJSON, ESRI Shapefile, GeoPackage, WMTS, MapBox Vector Tiles and QGIS. We even include sample Open Source mapping clients - MapLibre-GL and MapTiler-GL - so you can host your own maps quickly and easily.

No! Just go to map.opensite.energy to start using the Open Site Energy data layers.
It takes between 2 and 20 hours to generate the final Open Site Energy GIS layers, depending on the number of constraint layers required. In tests it was possible to create an onshore-wind-only constraint map in 2.5 hours (see this link) and we’re working on reducing this time even further.
Good point! There are so many renewable site maps out there already…
If you already create a wind or solar map, feel free to use all or any of our underlying technology or processes. We’ve tried to make our solution as streamlined and efficient as possible by using the very best technologies and solutions.
More generally, our strategic goals are:
- To see more wind and solar projects in the UK.
- To standardise and streamline the process as much as possible so that everyone – from community groups and wind developers through to local authorities and electricity networks – use the same underlying datasets and methodologies.
So if you think you have a better methodology, please get in touch so we can incorporate it into our data pipeline. Or… set up your own open data portal and data pipeline and we’ll happily redirect our website to yours!
Collaboration is key to achieving Net Zero, so if you’re interested in working with us, drop us an email at info@opensite.energy
