The dataset contains raw data from Ember’s Power System Modelling “New Generation”. The data shows least-cost power system pathways in 5 year time intervals from 2020 to 2050.

You can find the full report and insights from the modelling here.


The pathways are computed using the Artelys Crystal Super Grid power system modelling platform – a leading tool in European energy system planning. As input, assumptions about the energy sector (outlined above) are converted into hourly electricity demand profiles across entire years, taking into account increasing demand from a variety of new sources. Each type of new demand changes the profile of electricity demand in a unique way, across hours and seasons. While the study is focused on power system evolution (and decarbonisation) by 2035, all pathways were computed in 5-year time intervals between 2020-2050. This ensures investments before 2035 have foresight of possible energy system configurations beyond 2035. Hourly power system modelling was carried out, by which investments in and operation of the power system is optimised, minimising cost, while ensuring security of supply over the year – in line with European system security standards. Three years of actual historic weather data was used to simulate every modelled year, of which an average is typically presented. This ensures that a variety of weather conditions and their impact on wind and solar output are accounted for. The impact of weather (temperature) on demand is also included, particularly important as heating is increasingly electrified and cooling demand grows.
