Fixed or dynamic contract: which is cheaper?
That depends on when you use electricity. A dynamic contract is often cheaper if you can shift consumption to cheap hours, for example with an electric car or a home battery. A fixed contract gives you certainty about the price.
With a dynamic contract you pay the market price per quarter hour or per hour, plus the supplier's purchase mark-up and energy tax. On sunny afternoons and at night electricity is often cheap, in the early evening expensive. With a fixed contract you pay the same rate every hour.
Comparing suppliers
With dynamic contracts all suppliers use the same market prices; they differ in the purchase mark-up, the fixed costs and how they pay for feed-in. Energie27 compares fixed contracts on the model contract every supplier has to publish, without welcome bonuses or promotions. That way you compare what you keep paying after the first year.
Without net metering
From 2027 what a supplier pays or charges for electricity you feed back also counts. With solar panels the cheapest contract may therefore be a different one than now.
