SIMULATE
Price formation, hands-on.
A stylized single-zone merit-order model. Move demand, fuel and carbon prices and renewable output — watch the clearing price, the generation mix, capture rates and negative-price hours respond. Then ask the AI what the scenario teaches.
capacity blocks sorted by marginal cost · solar at 75% of peak output for the snapshot hour · hover blocks for detail
hourly clearing prices with standard demand, solar and wind day-shapes · red dots mark negative-price hours
Stylized model: fleet of 8 GW nuclear, 8 GW lignite, 12 GW hard coal, 25 GW CCGT, 10 GW OCGT, 4 GW oil; standard efficiency and emission factors; marginal-cost bidding. Battery: 4-hour storage charging in the day's 4 cheapest hours and discharging in the 4 most expensive. Peak-fleet modes: full fleet · peakers retired (scarcity at VOLL appears) · strategic reserve (peakers replaced by a 14 GW reserve activated at €500/MWh). Explore how carbon reorders coal and gas, how solar erodes its own capture rate, and how a battery compresses the TB4 spread it lives on.
