Curtailing and compensating RES can be cheaper than taking up 100% of RES electricity through investment into conventional plant park or transmission.
Curtailment should be considered as a regular flexibility option. It helps to mitigate the green-coal paradox and to reduce system emisions from 94 to 40 Mt CO2.
Analysis of curtailment as a flexibility option in the short and long run, including mitigation of the ‘green-coal paradox’ and comparison with hardware solutions. Overview of curtailment experiences across the world.
Progress on ensuring of the NEURC’s independance, unbundling and PSO on gas market, and launching the NECP development process. Key priorities in energy policy for the new administration.
The concentration of wind and solar plants in high-yield regions increases balancing needs and grid constraints. We recommend introducing a transparent curtailment charge mechanism.
Wind and solar installations should be distributed over the country. Policy should strive for an optimal mix of wind and solar installations in order to reduce system cost.
