Cost potential curves for renewables: a geospatial analysis

We are pleased to present our new strategic insight report ‘Cost potential curves for renewables: a geospatial analysis’. In the report, we present our comprehensive analysis on the build-out potential for renewables in Germany. Reaching mid- and long-term climate targets requires a fundamental transformation of the German energy sector and a tremendous buildout in renewable capacity.

In this report, we take a close look at the actual build-out potential for renewables in Germany, given geo-technical, economic, and socio-political constraints.

Key messages from this analysis are:

  • Germany has a geo-technical supply potential from wind and solar about three times its current power demand. However, LCOEs differ substantially between technologies and locations
  • The economic renewable potential is limited to about 30-40% available sites due to cannibalization effects. For onshore wind, site quality will increasingly matter. However, scarce site quality does not result in a capture price floor
  • Geo-technical supply potential is large enough to reach mid- and long-term renewables targets. If the onshore wind bottleneck persists, reaching the 65% RES target in 2030 would require a challenging 9-11 GW of solar additions per year. To achieve Net Zero in 2050, the onshore wind bottleneck could be offset by higher wind offshore and solar PV build-out
