When every solar plant in a bidding zone generates at the same midday hour, supply outstrips demand and day-ahead prices can go negative. A plant that keeps feeding in during those hours is paying the market to take its power.
Negative price avoidance means forecasting those windows before they happen and reducing day-ahead nominations accordingly — then recovering value intraday when prices recover.
How the strategy works
Samawatt's AI forecasts prices and production down to the individual plant, recalibrated every 15 minutes. When a negative-price window is forecast, the engine automatically shifts volume out of day-ahead nominations for those hours.
During the day, intraday re-trading captures recovering prices, and real-time imbalance management keeps deviations off your settlement statement.
What is it worth?
For a 100 MW German solar portfolio, avoided negative-price hours plus improved intraday capture typically contribute a meaningful share of the total uplift — our illustrative model puts total additional trading revenue at around €855,000 per year.
