Our verdict

Rheinpower suits German households that want electricity and gas from a single supplier, with a fixed or green tariff and support by email and phone. An offer score of 8.7 and a trust score of 8.5 point to a steady, utility-backed choice rather than a bargain hunter's pick.

Pros and cons

Pros

  • Electricity and gas sit with the same supplier under electricity and gas, so a dual-fuel home can settle both without shopping around twice.
  • The green tariff is 100% renewable and rests on certificates, which suits buyers who want renewable supply without building their own generation.
  • Tariff choice runs fixed, variable and green, so you can lock a price, follow the market or move to green without changing supplier.
  • Fixed terms of 12 and 24 give households room to plan their budget, and the legal entity behind the brand is Stadtwerke Duisburg AG.
  • Support runs on email and phone, so a question can go to a person by phone rather than sitting in a message queue.

Cons

  • Support runs on email and phone only, so quick questions rely on email or phone rather than a chat or a help centre.
  • A fixed term of 12 and 24 ties you in longer than a rolling monthly deal, which matters if you plan to move house.
  • The fixed, variable and green range has no dynamic pricing, unlike Powerpeers whose dynamic, fixed and variable include a dynamic tariff.
  • The green tariff is backed by certificates, so buyers who want the supplier's own generation may see this as a less direct route.

Who it suits

  • German households that want electricity and gas from Stadtwerke Duisburg AG rather than a small reseller.
  • Households that want 100% renewable supply through certificates and prefer a plan fixed for 12 and 24.
  • People who value reachable support, since help runs on email and phone and includes a phone line.

Who should look elsewhere

  • Powerpeers, if you want dynamic pricing, since dynamic, fixed and variable includes a dynamic tariff and Rheinpower's fixed, variable and green does not.
  • Electricity Ratings, if you need an electric vehicle or prepay tariff, since fixed, ev and time of use lists both and fixed, variable and green does not.
  • Endesa, if your usage follows cheaper hours, because fixed, time of use and ev includes time-of-use and Rheinpower's fixed, variable and green does not.

Who runs it

Rheinpower is supplied by Stadtwerke Duisburg AG, the municipal energy company behind the brand, and its headquarters country is DE. The company has been trading since 2009, which puts it well beyond a new entrant and means your contract sits with an established operator rather than a short-lived reseller. If you already buy electricity and gas, the same legal entity handles both, which keeps a single point of contact for billing queries and meter changes. Support runs on email and phone, so you can pick up the phone as well as send an email. For a household that prefers a named, long-established supplier with a human route in, that pairing is the main draw. A newer name may offer a sharper introductory deal, but the counterparty you sign with here is the kind of local utility that has supplied households for a long stretch.

Frequently asked questions

Who actually supplies Rheinpower?+

Rheinpower is supplied by Stadtwerke Duisburg AG, a municipal energy company whose headquarters country is DE. The brand has been trading since 2009, so the contract you sign sits with an established operator rather than a new entrant. That matters most if you put weight on a named counterparty over a headline introductory price.

Where can I get Rheinpower energy?+

Rheinpower supplies in Germany, and its stated region is Germany. An address outside that market therefore sits outside its supply area, so a move abroad of the region would mean changing supplier. The same company handles electricity and gas, which makes it one contact for a dual-fuel home.

What tariffs does Rheinpower offer?+

Rheinpower's fixed, variable and green cover the main choices: a fixed price, a variable option that follows the market and a green tariff. Fixed contracts run 12 and 24, so you can take a shorter commitment or a longer block. The range has no dynamic pricing for households wanting hourly tracking.

Does Rheinpower supply gas as well as electricity?+

Yes, electricity and gas covers electricity and gas from the same company, which is convenient for a home running a dual-fuel supply. A shared account also means a single bill to track and the same support contact when a reading is disputed, instead of chasing two suppliers about the same problem.

How green is the Rheinpower green tariff?+

The green tariff is 100% renewable and rests on certificates, so the renewable claim comes through certificates rather than the supplier's own plants. That suits buyers who want renewable supply without installing their own generation, while buyers focused on physical generation may prefer a supplier that runs its own power stations.

How do I contact Rheinpower?+

Support runs on email and phone, so you can email or phone. A phone line suits households that would rather talk through a bill or a meter reading, while email keeps a written trail for anything you may need to refer back to later. Your contract documents will carry the current contact details.

How long is the Rheinpower contract?+

Fixed terms run 12 and 24, so you commit for a full year or a longer block and the price holds for that period. That suits households wanting budget certainty, but it is a longer tie than a rolling monthly deal, so plan ahead and check the notice period before you move house.

How does Rheinpower compare with Powerpeers on tariff choice?+

Powerpeers lists dynamic, fixed and variable, which adds a dynamic tariff for tracking prices by period. Rheinpower's fixed, variable and green cover fixed, variable and green options instead, with no dynamic pricing in the range. If period-by-period tracking appeals to you, Powerpeers is the more relevant name to compare.
