Associated causal chains

This component is part ofInstallation causal chains— from cause to effect (gas quality → engine → exhaust gas → heat → efficiency). The AI reads the entire chain, not just the individual value.

Link with the entire installation

A CHP unit is never alone: electricity, heat and gas are linked, and with PV and battery storage, it becomes a system. The AI calculates the entire installation.

Frequently Asked Questions

What does modulation mean for a CHP unit?
Modulation is the continuous adjustment of the gas engine power between approximately 50% and 100% of the nominal power.
From what point does efficiency decrease in partial mode?
Below a load of approximately 50%, specific gas consumption increases measurably and overall efficiency decreases.
Why is the modulation limit important for profitability?
It defines the zone in which the CHP unit operates efficiently enough to optimise fuel costs relative to output.
How does modulation affect the CHP Baseline?
Correct modulation ensures that the baseline values for gas consumption and electrical efficiency remain stable and predictable.
Can a CHP unit be operated at a load of 50%?
Technically, it is possible, but this leads to significantly lower efficiency and increased wear due to unstable combustion conditions.
What role does modulation play in direct sales?
It allows the operator to flexibly adapt the CHP unit to current market prices without leaving the optimal operating range.
