Renewable Energy Complementarity (RECom) Maps – a comprehensive visualisation tool to support spatial diversification

Til Kristian Vrana and Harald G. Svendsen

Abstract. Maps showing the mean wind speed only give an inaccurate indication on the quality of locations for future wind power developments. Calculating the capacity factor (based on a weather time series and a wind turbine power curve) and plotting that on a map gives a better indication on the expected mean power output, but the outcome depends on the turbine choice. In this article, the mentioned dependency is compensated for by putting the expected mean power output in relation to the expected mean power output of all other wind parks of the region (assuming that they use the same turbine type). This relative capacity factor results in nice comprehensive wind resource maps, and can be plotted for the situation today and also for a future scenario. Since the expected income of a potential wind park is the product of mean power output and mean market value, looking at the relative capacity factor only does not give the full picture. The mean market value is influenced by the merit order effect that is mainly driven by covariance with other wind parks and the capacity factor's relation to production at low-wind moments. A market value factor is introduced that captures the expected mean market value relative to other wind parks, based on a simplified power market model. Finally the RECom index is defined, combining the relative capacity factor and market value factor into a single index, resulting in the RECom map. This map can comprehensively show the revenue potential of different locations for potential future wind power developments.

Short summary
We developed new ways to plot nice and comprehensive wind resource maps that show the revenue potential of different locations for future wind power developments. The relative capacity factor is introduced as an indicator showing the expected mean power output. The market value factor is introduced, that captures the expected mean market value relative to other wind parks. The RECom index combines the two into a single index, resulting in the RECom map.
