Life cycle costs and carbon emissions of wind power: Executive Summary

Research output: Book/ReportCommissioned report

Abstract / Description of output

- Capital cost is a major determinant of levelised costs but production levels and, particularly, financing assumptions are important determinants of headline costs; UK-studies showed above average levelised costs largely as a result of above average discount rates;
- The cost of offshore wind is more uncertain and higher than onshore wind and other established technologies, but there is significant scope to reduce costs to comparable levels;
- The introduction of wind power does result in impacts on the electricity system in terms of costs for balancing, transmission and backup, but these are modest at around 10% of the cost of wind energy;
- The life cycle carbon emissions from both on- and offshore wind are very low at 15 and 12 gCO2eq/kWh, respectively;
- Wind power variability affects system operation and reduces the efficiency of coal and gas generation, but the impact is modest, and emissions savings due to wind power will remain significant.
