A fixed energy price is the most expensive peace of mind you can buy
A fixed tariff has to be the most expensive tariff on the market. That is not a conspiracy of suppliers — it is mathematics. And that cost of peace of mind is only going to rise.
Convenience that has its price
For years, the fixed tariff seemed the obvious choice. Predictable. Easy to convert kilowatt-hours into cost. You put it in the budget and forget about it. Not so long ago, directors responsible for energy procurement would assure me with a slightly impatient smile that they "have no problem with energy, because they have a long-term contract at a fixed price".
Then came capacity charges, and some of those smiles evolved towards a grimace. But that is a subject of its own.
What matters here is a fact that gets lost somewhere along the way: a fixed tariff has to be the most expensive tariff on the market. It cannot be otherwise.
Brutally simple logic
The supplier buys energy at market prices — whether from the exchange, from a PPA or from a mix of sources makes no difference. And it has to sell at a price known in advance and unchanged for 12, 24 or 36 months, as the customer wishes.
Between those two points lies the whole energy market with all its risks: price volatility on the exchange, weather, new regulations, exchange rates, capacity availability, geopolitics, drought and whatever else we cannot yet even name (we sometimes call it a "black swan").
The supplier has to fit all those risks somewhere. And there is only one place: in the price it has just offered you.
That is why a fixed price will almost always be higher than any other in which the supplier can share at least part of the risk with the customer. Not because anyone means ill — because nobody sells something for less than it costs them, plus margin, plus a buffer for what can go wrong.
Why that cost will rise
The most interesting part is what happens next. Risks in the energy market are not shrinking — they are growing. Every further year adds new unknowns. And the more unknowns there are, the larger the buffer built into the fixed price has to be.
The conclusion? The fixed tariff will get more and more expensive relative to every alternative. Not because someone changed the rules of the game, but because the rules stayed the same — the market simply picked up speed.
Peace of mind has a price
You can, of course, carry on paying for peace of mind. You just need to know that peace of mind has a price — and that price will rise faster than the market average.

Percee offers a third way between market risk and expensive peace of mind: instead of buying predictability from the supplier, the company generates it on its own side of the meter. The system reads day-ahead prices, shifts consumption into cheaper intervals and keeps an eye on contracted power, so the bill is not only lower but also more predictable. It is the same predictability you pay for in a fixed price — and at Solwena's customers it means a 15–40% lower energy cost, across more than 50 deployments.
