• REmap A Renewable Energy Roadmap IRENA International Renewable Energy Agency Instantaneous penetration of VRE Instant Penetration (%) 120 100 80 60 60 40 40 20 20 No curtailment 75% limit 55% limit Up-to 10% of total electricity that could be generated by renewables by 2030 may need to be curtailed to guarantee system security (55% limit) The use of the most up-to-date technologies and operational practices in the future may help reduce curtailment to less than 2% (75% limit) 20 40 60 80 100 Percent of hours of the year (%, sorted) System must be carefully analysed to identify penetration limits • Reasons for the constraints must be identified and solved Required and acceptable levels of curtailment have to be evaluated • Forward looking grid codes and operational practices could help to allow higher instantaneous penetration of VRE 27
