You may have noticed that curtailment* revenues are lower this year than last year. We’d like to provide a brief explanation and overview of the key developments.
Fewer hours with negative prices
In 2024, we saw fewer hours with negative prices, but these periods were often more extreme and therefore more valuable. In 2025, the picture is different: there are actually more hours with negative prices, but at lower average prices. In addition, production during those periods was often lower, and curtailment revenues are calculated more strictly. The result: net curtailment revenues are lower than in 2024.
More flexible installations
In addition, changing market conditions play a role. An increasing number of solar installations are now controllable. As a result, curtailment is occurring at higher power levels, which actually reduces the individual output per installation. Changes to market rules and settlement methods are also contributing to a less favorable outcome.
New Bidding Strategies
Finally, we see that producers and suppliers are adjusting their bidding strategies to avoid negative prices. They are increasingly submitting lower or different bids as a preventive measure, which makes price fluctuations less extreme and puts further pressure on curtailment revenues.
Repowered is responding to the changes
Repowered recognizes this trend and is responding to it as best we can. One way we’re doing this is with our newOptima algorithm! The trusted optimization our customers are already familiar with is now even smarter.
*Curtailment is the temporary reduction or suspension of electricity generation. This occurs, for example, at the request of the grid operator as part of congestion management, or when the electricity price is negative.
