Can I run a power cable to my neighbours?

No. Every home has its own connection and meter, and a fixed cable to another home is unsafe and not allowed administratively. Sharing through your charger does work.

Does it cost me money when my neighbour charges at my place?

On average, no. You pay your normal power price, and the ERE on every shared kWh (about €0.16) is yours. During the day on a dynamic contract that is more than the power costs.

Does my neighbour get my solar power?

On a sunny day a large share of the power comes from your own roof. The rest comes from the grid, like all your usage. The ERE payment is separate from that.

Sharing power with your neighbours: what really works?

A cable over the fence is not allowed. But sharing your power works: through your charger, and the ERE pays the bill.

Solar panels on your roof, a surplus around noon, and a neighbour who could use the power. Sharing power with your neighbours sounds logical. Yet a cable over the fence is not an option. What does work?

Why a cable to the neighbours is not allowed

Every home has its own connection and its own meter. Power that passes your meter belongs to your contract and your installation. A fixed cable to another home does not fit that: it is unsafe and the paperwork does not add up.

Rules for sharing self-generated power with others are in the works, and energy suppliers are experimenting. For most households it is not practically available today.

A car battery is the easiest place to share power. When your neighbour charges on your driveway, the power from your connection • on a sunny afternoon largely your own solar power • goes straight into their car. No cable over the fence, no changes to your installation: your charger is the sharing point.

And the bill?

The ERE pays it. Every home-charged kWh earns the owner of the connection an ERE credit: about €0.16 per kWh, based on our realised sale prices. During the day, power on a dynamic contract often costs less than that.
