What is heat-led vs. electricity-led operation?

Heat-led operation: CHP unit runs based on heat demand/gas storage level — typical for biogas plants; electricity-led operation: CHP unit follows electricity exchange prices (direct marketing) — increases revenue at high prices, reduces it during negative prices.

What the AI reads from these values

What the AI reads
  • Current heat demand as primary control parameter for load adjustment
  • Gas storage status to ensure continuous supply
  • Real-time comparison with electricity exchange prices to optimise feed-in revenue
  • Monitoring of plant runtime (e.g., 40,768 operating hours) for maintenance planning
Scenario

Monitored: continuous

The scenario: cycles the CHP unit too frequently, wear increases without an alarm being triggered, leading to a shorter service life and higher maintenance costs. The AI: detects the unfavorable operating pattern early and suggests a steadier mode of operation. It identifies the trend before the limit value is reached.

Why this matters

The choice of the correct operating mode optimises the profit margin through targeted feed-in during high spot market prices. Electricity-led operation maximises revenue in high-price phases and minimises losses at negative prices. Heat-led operation, on the other hand, ensures base load coverage and thermal process stability. work produced per year (kWh) · nominal output (kW) → — full load hours/year Calculation: work produced ÷ nominal output
