November 2025: entering a “Dunkelflaute”

In November, we experienced an exceptional Dunkelflaute: low solar production and little wind. As a result, energy supply relied mainly on fossil fuels, a market that remained unusually stable during this period.

That stability sounds reassuring, but it has consequences for smart energy optimisation:

• Lower solar production → higher grid consumption → higher energy bills

• Fewer price fluctuations → limited battery optimisation → lower battery savings

• Stable day-ahead prices → little difference between fixed, variable, and dynamic contracts → limited tariff savings

• Stable energy market → lower rPOWR and ePOWR revenues

Important to note: this is a market phenomenon, not a system issue. Your FlexiO system remained fully operational, simply waiting for better opportunities. Sometimes, doing nothing is the smartest move.
