Association Webinars: The Clean Energy Package and Wind Curtailment - Club goods and the tragedy of the commons



The EU is a club to collectively charge for climate damage by charging for CO2 emissions through the Emissions Trading system and supporting increased renewables to deliver learning-by-doing spillovers under its Clean Energy Package. Members publish National Energy and Climate Plans setting out their targets for renewables, mainly wind and PV. At high levels of wind penetration, surplus wind that cannot be exported must be curtailed. Marginal curtailment is 3-4+ times the average curtailment, but even in an efficiently designed market, price signals for wind investment are given by average not marginal curtailment, creating a "tragedy of the commons" that requires a corrective charge to restore efficiency. The webinar presents a model calibrated to Ireland in 2026, showing the source of distortion, and derives new formulae for the capacity credit of wind, the learning subsidy and corrective charge needed to deliver the efficient level of renewables penetration, and estimates of their magnitude.
