Main fuse size — are you paying for too much?

You pay a fixed monthly fee for your connection capacity (main fuse). If your actual peak is lower, you’re paying for nothing. Gridea shows whether you can safely reduce it.

What are you paying for?

The monthly connection fee is charged by the main fuse’s amperage — regardless of how much you actually consume. A larger fuse means a larger fixed cost.

Why do many overpay?

A connection was often sized years ago with more headroom than is needed today. If consumption has changed, the fuse can sometimes be reduced and the fixed fee drops.

How does Gridea help?

Gridea looks at your actual 12-month peak and shows whether the fuse can be safely reduced — and how much that saves per year.

Frequently asked questions

What is the main fuse size?

It’s the maximum permitted current of a connection point, in amperes. The monthly connection fee is charged against it.

Can the fuse be reduced?

Often yes, if the actual peak stays lower. Gridea shows the 12-month peak and recommends a safe level.

How much does reducing it save?

It depends on the connection, but the fixed fee drops with every ampere reduced. Gridea calculates the exact annual saving.
