Starting October 1, 2025, European countries’ day-ahead markets are moving from hourly electricity pricing to 15-minute pricing, or Market Time Units (MTU). This is one of the biggest shifts in the energy market in decades, designed to make pricing more precise while more renewable energy is integrated into the grid.
But with change comes questions: What does this mean for my home, my contract, and my heating system?
At Kapacity.io, we’ve prepared for this major change in the energy market to ensure a smooth transition for the heat pump owners.
From October 1 onwards, Kapacity.io will support both hourly spot prices and 15-minute spot prices for heat pump optimization. No matter what type of electricity contract heat pump owners have, Kapacity.io provides optimal control for your heat pump.
Which control, 1h or 15 min is best for my heat pump?
This change impacts heat pump owners with spot price based contracts. Optimal heat pump control setting depends on your electricity contract and electricity meter. Some electricity providers will move directly to 15-minute pricing, others will keep hourly contracts. To be sure, check your electricity contract details or reach out to your electricity supplier.
Select 15 min based control
- when your electricity contract is based on 15 min prices and you have a new smart meter that supports 15 min measurements
Select 1 h based control
- when your electricity contract is based on 1h prices OR you have an old smart meter that does not support 15 min measurements
Is 15 min price control safe for my heat pump?
Yes, when done correctly. Heat pumps are precise machines that require careful handling according to manufacturer guidelines. Kapacity.io always puts equipment safety and your comfort first.
