In cooperation with Liander, an exploratory impact analysis was carried out in 2020 on the social value of curtailment – limiting the feed-in capacity of customers with renewable generation in the event of occasional peak loads.
Why? Liander is running up against the limits of the grid’s capacity at various locations. Renewable generation locations require a relatively high transmission capacity in order to supply the grid during occasional peak loads. Liander is investigating the possibility of increasing the grid’s capacity by capping these peaks, also known as curtailment.
The analysis shows that, on balance, curtailment has a positive impact on society. In the case under consideration, curtailment brings the optimum to approximately 85% of the installed capacity. The extra costs for Liander (compensation) and the government (SDE subsidies) are lower than the value created by the accelerated connection of new sustainable production locations.
