What a dynamic price actually is
The guest pays the day's electricity price plus a fixed markup. When electricity is cheap overnight, charging is cheap. When electricity is expensive, the price reflects that too. The markup does not change, so nothing is hidden inside the movement.
A fixed price cannot do this. It has to be set high enough to survive the most expensive hours of the year, which means the guest overpays every other hour.
For the guest: no holiday premium
A guest charging overnight at a hotel has no way to check whether the price is fair. A fixed price asks them to trust it. A price tied to the market removes the question — it is the same electricity price the market pays, plus a markup that is the same everywhere.
The guest never pays over the odds, and the receipt matches something they can verify. That is why charging does not turn up as a complaint in the review.
For the host: the price is not your problem
The host earns 1 krone per kWh delivered. That amount does not move when electricity does. No repricing, no negotiation, no explaining a number to a guest at reception.
The host keeps their own electricity agreement for the property, exactly as before. The charging price is set by the market, not by the host — so a price question at the desk has a one-line answer.
For agencies and chains: nothing to administer
A portfolio of properties normally means a portfolio of prices to review, defend and update. Here there is one rule and it applies everywhere: the day's electricity price plus a fixed markup.
When electricity falls, the guest price falls the same day, without anyone touching a setting. Consistency across sites comes for free.
For the grid: charging moves to the quiet hours
Cheap hours are the hours with surplus power in the system. When the price follows the market, guests naturally charge when there is room on the grid — overnight, at a destination, exactly where slow AC charging belongs.
No campaign is needed. The price does the coordinating.
Where the model would break
A dynamic price only works if the markup is fixed and stated. A variable markup on top of a variable electricity price is not transparency, it is noise.
So the markup stays the same, whatever the day looks like. Electricity moves. Our markup does not. The host's krone does not.
