Yuso is absolutely not in favour of curtailment based on day-ahead prices, as curtailment based on imbalance prices is more advantageous for all parties: you, the electricity grid and Yuso.
The day-ahead price is not representative of the real-time needs of the electricity grid; only the imbalance price is.
Curtailment based on day-ahead prices can provoke an undesirable reaction from a system perspective: in real time, there may be a shortage of electricity. Only control based on the real-time price, the imbalance price, therefore helps to improve grid stability.
Day-ahead curtailment leads to higher imbalance costs, which are passed on to injection customers.
It is the supplier who is charged for the imbalance costs caused by day-ahead curtailment, as described above. To protect itself against these negative consequences, the supplier faced with this situation will increase its compensation for imbalance risk. This is, of course, always to the detriment of the end customer.
Yuso passes on these imbalance costs via the BSI. A rising imbalance cost for solar energy, caused by day-ahead curtailment, thus also has an indirect effect on your injection settlement.
Yuso offers curtailment on imbalance. This creates a win-win situation for both parties and the system.
Curtailment based on imbalance prices will not only yield more for you as an end customer, it also contributes directly to grid stability.

Our mission at Yuso is to accelerate the transition to a sustainable electricity system. We believe that transparent and market-driven solutions are the ideal tool for this. PV curtailment on imbalance is one of our solutions; our battery control and consumption control work on the same principles.
