FAQ – Green Electricity

Answers to your most frequently asked questions about our green electricity.

Switching to Grünwelt Energie

By switching to an electricity tariff from Grünwelt Energie you benefit in several ways: thanks to our lean organisation we offer cost-effective tariffs and supply you with 100% sustainable green electricity certified by TÜV NORD from European hydropower. That is good for the environment and gentle on your wallet at the same time. Of course, we do not skimp on service – our friendly customer service representatives are at your side with advice and support for any matter relating to your energy supply.

Every electricity customer with their own meter can switch to us comfortably and securely. Simply enter your postcode and consumption in our tariff calculator and you will receive a non-binding price quote. Then click the "Order" button and we will guide you step by step through the ordering process – of course over an encrypted connection. At the end you will receive an order confirmation that you can print for your records. A few days later you will receive your contract confirmation. In the meantime we already take care of all formalities. We cancel your old electricity contract if needed and switch you to our affordable tariffs at the agreed delivery date without any interruption to your electricity supply.

If you rent an apartment with its own electricity meter, you can switch to us without any problem. The same applies if you rent a house. If you live in a multi-family building without your own electricity meter, you should ask your landlord or property manager about a switch, since the meter may be shared between several residents.

For your electricity supplier switch you will need the number of your electricity meter, the market location ID (MaLo-ID), last year's electricity consumption and your customer number from your previous supplier. As a rule, all of this information can be found on your last electricity invoice. We also need your delivery address and, if applicable, a direct debit authorisation or a SEPA mandate. All data is transmitted via an encrypted connection and handled in accordance with the German Federal Data Protection Act.

As a rule you do not have to cancel your existing electricity contract yourself, since you can grant us a power of attorney to do so as part of your order. We then cancel your old electricity contract for you in good time before the delivery date and take care of all formalities. The only exception: if you wish to switch to us due to a price adjustment or another short-term termination right, you should cancel the contract yourself because of the tight timeframe. In that case please give us the end date of your contract when ordering.

No, there are of course no costs for switching to us.

If you are already a Grünwelt Energie customer and are interested in placing another order, please give us a call – our friendly service experts will gladly check together with you which options are available for your contract. You can reach our customer service via our contact addresses.

Delivery date: how long does the switch take?

For switching electricity suppliers, statutory deadlines apply that all providers must adhere to. If your previous contract does not have longer notice periods, it takes around four weeks from your order to your supply. Shortly after your order you will first receive a contract confirmation with a likely start date for delivery. We then cancel your old electricity supply contract and register your delivery point with the responsible grid operator. Both your previous supplier and the grid operator must confirm these steps to us. Once we have the green light from both, we will inform you immediately of the good news with a delivery confirmation.

We make every possible effort to meet your desired delivery date. For the supplier switch, however, we also rely on the cooperation of your previous provider and the local grid operator. Should there be any problems, we will of course inform you immediately and look for a solution right away so that you can be supplied as soon as possible.

Yes, you can submit an order to us in advance even if your old contract still has a remaining term. The remaining term of your old contract may be up to 12 months.

Yes – if you make use of a special right of cancellation you can let us know the contract end date within your order. We will then note that date for your supply.

For the meter reading at the start and end of your electricity supply, your grid operator will contact you to obtain a reading. We recommend that you also report your meter reading to your grid operator in any case and keep a note of it for your records.

No – statutory regulations make it impossible for a supply interruption to occur when switching electricity providers. The local backup supplier ensures continuous electricity supply at all times – even if there should ever be a problem.

Payment and billing

We first calculate your expected invoice amount for the coming year and then divide it into equal monthly installment amounts so that the year-end statement results in the smallest possible difference. The exact amount and payment dates can be found in your delivery confirmation. You can pay your installments by SEPA direct debit or bank transfer.

The base price is a fixed annual basic charge in your contract that is billed monthly. The working price is the variable charge per kilowatt-hour of electricity consumed.

The expected invoice amount for the coming year is divided into monthly installments, so that at the end of the billing year there is as small a difference as possible. To do so, your consumption is multiplied by the working price per kilowatt-hour and the annual base charge is added. Divided across the individual months, the result is the monthly installment amount. Any new customer bonus that has been agreed is not included in the monthly installments because it is paid out to you on the dates agreed in the contract.

To calculate your installment we use the most recently known consumption volume for one year. If you wish to change your installment during the year, you can request this together with a meter reading from our customer service. If your annual consumption has changed, we will then adjust your installment plan accordingly.

After one supply year we will first ask you to send us your meter reading. We then create your consumption invoice for the past year on the basis of these meter readings and the information from your responsible local grid operator, and send it to you.

Our affordable electricity tariffs are made up of a variety of price components. In addition to procurement and sales costs, these include the grid charges, state-imposed charges as well as taxes and levies. On our Electricity price information page you can view the price components in detail.

Some tariffs include a new customer bonus. This bonus can be granted as a percentage credit on the total cost of the electricity supply within the first year of supply or as a bank transfer after a certain number of days following the start of supply. The respective conditions and the amount of the bonus depend on your tariff and are stated in detail in your order form, our terms and conditions and the contract confirmation.

If we have agreed a limited price guarantee, we may not change the prices during this period. Excluded are changes to the EEG levy, the CHP (KWK) levy, the levy under § 19 StromNEV, the offshore liability levy, the levy for interruptible loads, the concession fee, the electricity tax and the VAT. Also excluded are price changes resulting from new taxes, levies or other state-imposed burdens or relief affecting the procurement, generation, network use (transmission and distribution) or consumption of electrical energy in the future. § 6 of our terms and conditions applies to price changes.

Moving and moving in

Please notify us of your move at least two weeks in advance, for example via our contact form. We are happy to supply you at your new address with our affordable tariffs. Please contact us by phone or email and we will gladly make you an attractive offer.

If you move into a new property as the first occupant and want to be supplied there with affordable Grünwelt tariffs, this can take up to 2 working days. Otherwise, the local default supplier (Grundversorger) will initially supply your new home with electricity on a transitional basis. Please tell us your desired delivery start date as part of your order.

When you move into an apartment we need, among other things, the planned move-in date and the meter number of the apartment in question. As a rule you can obtain this from your future landlord on request.
