Why was October more expensive than September?

Mostly the dark evenings: you used more after six. And your price is variable, and it went up.

Conversation with Pulsy

That one line on your bill

Since 2023, households in Flanders also pay for their peak: the quarter of an hour in which you drew the most power at once. Hardly anyone knows how high that peak is, or when it happened. Pulsy finds out for you.

Flemish annual electricity statement, in Dutch. The capacity tariff line, average 3.62 kW, €204.12, is highlighted. Still to pay: €52.77.

How it works

  1. Upload a bill or connect your digital meter

    A recent bill or your annual statement is enough to start. With a digital meter, Pulsy also sees your use per quarter hour.

  2. Pulsy calculates with your contract

    No average prices, but the rates in your own contract, Fluvius's network tariffs and your own peak.

  3. Pulsy lets you know

    A new peak, or a contract that has become too expensive: you get a short message, with the amount. You can always ask something yourself too.

What Pulsy tells you

You don't have to go looking. When something changes that costs or saves you money, you get a short message.

    New monthly peak: 4.1 kW

    Yesterday between 18:45 and 19:00 the oven, the dishwasher and the car charger ran at the same time. That peak counts for a full year: roughly €3 extra in capacity tariff.

    Your contract is pricier than the market

    For your usage you pay about €180 a year more than with the sharpest contracts this month. Switching is free.

  • Pulsy3 Nov

    Your base load went up by 40 W

    At night you now use 40 W more than last month. That's about €100 a year. Often it's an old freezer or fridge.

    Car charger and dishwasher get in each other's way

    Every evening around 19:00 they run at the same time. Charge the car from 22:00 and your peak drops from 4.1 to about 2.9 kW.

    A home battery doesn't pay off for you yet

    With your solar panels and your usage, a 5 kWh battery pays for itself in about 14 years. That's longer than such a battery lasts.

Questions

What does Pulsy cost?

That hasn't been decided yet. Leaving your email address is free, and it doesn't commit you to anything.

What happens to my data?

We use it to work out your energy costs, and for nothing else. We don't sell it, and you can have it deleted at any time.

Does it work in Brussels or Wallonia?

Not yet. We're starting in Flanders, because network tariffs and the capacity tariff differ per region. The rest of Belgium comes later.

Do I need a digital meter?

No. A bill is enough to start. A digital meter makes it more precise, because Pulsy then sees when you use power.

When can I use Pulsy?

There's no date yet. If you leave your email address, you'll be the first to know.
