Calculate CCGT plant profitability, clean spark spread, and breakeven gas prices across European bidding zones. Built for power traders, asset managers, and energy analysts.
The spark spread represents the theoretical gross margin of a gas-fired power plant (Combined Cycle Gas Turbine — CCGT) selling power and buying natural gas fuel. The clean spark spread further accounts for carbon emissions costs under the EU ETS.
A positive spark spread indicates gas power generation is economic in that hour, whereas a negative spread means operating the CCGT plant would result in a financial loss compared to remaining offline.
Thermal efficiency varies across plants: modern H-class turbines reach up to 60-63% efficiency, while older F-class units operate closer to 50-55%. Lower efficiency plants require higher power prices to break even.
