First Electricity in Cologne: RheinEnergie Covers You Automatically
RheinEnergie is Cologne's Grundversorger, the basic supplier, for electricity, gas, and water combined, a single-utility structure similar to Munich's SWM or Frankfurt's Mainova rather than Berlin's split between separate electricity, gas, and water companies. If you move in and don't actively choose a provider, RheinEnergie's own guidance confirms basic supply kicks in automatically: "If you don't report to us and haven't concluded a contract with us, basic supply automatically applies," so there's no gap in service even if you do nothing. To register properly, whether accepting the automatic Grundversorgung or signing a specific contract, you need your new address, the meter number, and a meter reading taken on your actual move-in day, ideally submitted online as soon as your move date is confirmed rather than after the fact. Current basic tariff sheets (Preisblatt Strom Privatkunden and Preisblatt Erdgas Privatkunden) are published directly by RheinEnergie rather than summarized on the general overview page, so check those PDFs for exact rates.
The Official Rule
RheinEnergie is Cologne’s Grundversorger, the default basic supplier, for electricity, gas, and drinking water combined. That’s a single-utility structure, closer to Munich’s SWM or Frankfurt’s Mainova than to Berlin’s model, where electricity (Vattenfall), gas (GASAG), and water (Berliner Wasserbetriebe) run through entirely separate companies.
If You Do Nothing, You’re Still Covered
Here’s the detail worth knowing upfront: RheinEnergie’s own guidance states plainly, “If you don’t report to us and haven’t concluded a contract with us, basic supply automatically applies.” You’ll receive a contract confirmation with your customer number once the system catches up, and there’s genuinely no gap in service even if you move in and take a while to sort out the paperwork. The tradeoff is cost: Grundversorgung tariffs tend to run higher than a specifically negotiated contract, so treat the automatic fallback as a safety net, not a plan to rely on long-term.
What You Actually Need to Register
| Item | Detail |
|---|---|
| New address | Your move-in address |
| Meter number (Zählernummer) | Found on the meter itself |
| Meter reading (Zählerstand) | Taken on your actual move-in day |
Third-party guidance confirms the meter reading specifically should be taken on the day you move in, not estimated or backdated, since that reading anchors where your billing period actually begins.
- Confirm your move date and register as soon as it's decided, not after you've already moved in.
- Gather your address, meter number, and (once you're in) your meter reading.
- Register through RheinEnergie's OnlineService portal, which takes just a few minutes if you have all the data ready.
- Specify your move-in date or lease start date as the supply start date when you sign up.
- If you skip this step entirely, automatic Grundversorgung still applies, you'll just likely pay a higher rate than a negotiated contract.
Where to Find Actual Current Prices
RheinEnergie doesn’t list specific rates on its general Grundversorgung overview page, instead pointing to separate, periodically updated PDF documents: Preisblatt Strom Privatkunden for electricity and Preisblatt Erdgas Privatkunden for gas. Check those directly rather than relying on a number repeated elsewhere online, since basic supply tariffs can shift between publication cycles.
Step by Step
- As soon as your move is confirmed, note the date and prepare to register, don’t wait until you’ve already moved in.
- On your actual move-in day, read your electricity meter and note the Zählernummer and Zählerstand.
- Register through RheinEnergie’s OnlineService, providing your new address, move dates, meter number, and reading.
- If you’d rather choose a specific tariff than the default Grundversorgung, check RheinEnergie’s current Preisblatt documents or compare other providers before signing.
- If you do nothing, confirm you’re still covered by automatic Grundversorgung, but expect a higher rate than a negotiated contract, and switch when convenient.
- Keep your contract confirmation and customer number once it arrives, you’ll need it for any future account changes.

FAQ & Common Pitfalls
What actually happens if I just don't register anything?
Nothing bad, at least not immediately. RheinEnergie's own guidance states plainly that if you don't report your move and haven't signed a specific contract, basic supply (Grundversorgung) automatically applies. You'll receive a contract confirmation with a customer number once the system catches up with your usage. The main downside is that Grundversorgung tariffs tend to run higher than a specifically negotiated contract, so treat "doing nothing" as a safety net rather than a cost-effective long-term plan.
What three pieces of information do I actually need to register?
Your new address, the meter number (Zählernummer), and a meter reading (Zählerstand). RheinEnergie's guidance is specific that the reading should be taken on your actual move-in day, not estimated from a previous date, since that reading is what determines where your billing period starts.
When should I actually submit the registration?
As soon as your move is confirmed, ideally before the move-in date itself. RheinEnergie's own advice is direct: register as soon as the move is decided, and you can specify your actual move-in date or lease start date as the electricity supply start date when signing up. Registering early doesn't start billing early, it just means the paperwork is already done when you actually need supply.
Does RheinEnergie also handle gas and water the same way?
Yes, RheinEnergie functions as Cologne's combined Grundversorger for electricity, gas, and drinking water, a structure closer to Munich's SWM or Frankfurt's Mainova than Berlin's model, where electricity, gas, and water run through separate companies (Vattenfall, GASAG, and Berliner Wasserbetriebe). If you're setting up gas alongside electricity, the same registration process and the same automatic Grundversorgung fallback apply.
How long does online registration actually take?
RheinEnergie's own guidance states that if you have all the relevant data ready, your new address, move-out and move-in dates, meter number, and meter reading, registering through their OnlineService portal takes just a few minutes. Gathering the meter reading itself is usually the part that takes the most planning, since it has to happen on the actual move-in day.
Where do I find the actual current prices?
RheinEnergie doesn't summarize exact rates on its general Grundversorgung overview page, it points you to separate PDF price sheets instead: Preisblatt Strom Privatkunden for electricity and Preisblatt Erdgas Privatkunden for gas, both published directly by RheinEnergie and updated periodically. Check those documents directly for current figures rather than relying on a number that may already be outdated by the time you read it.
