3.2. Maintenance services are not offered.
4. How and with whom is a contract concluded? How is the contract communicated?
4.1. The conclusion of a contract may be initiated in particular online via the PLAN-B NET ZERO ENERGY website or via other sales channels approved by PLAN-B NET ZERO ENERGY.
4.2. PLAN-B NET ZERO ENERGY concludes the contracts with grid operators that are required to carry out the supply. This includes in particular the necessary grid usage processes and, where applicable, the involvement of the default metering point operator.
4.3. Quotes prepared on the basis of the customer's information do not constitute a legally binding offer by PLAN-B NET ZERO ENERGY.
4.4. The customer only submits a binding offer to conclude an electricity supply contract by signing the order form or, online, by clicking the “Order with obligation to pay” button. Until the binding submission, the customer can correct their details using the correction tools provided in the ordering process.
4.5. If the customer states a change of supplier as the reason for the order, PLAN-B NET ZERO ENERGY carries out the change of supplier in accordance with the applicable statutory provisions and the processes of the market participants involved. The customer is bound by the validly concluded contract in accordance with the agreed contractual terms. Statutory rights of withdrawal and termination remain unaffected.
4.6. PLAN-B NET ZERO ENERGY may handle the termination with the previous supplier on behalf of the customer. If there is a special right of termination vis-à-vis the previous supplier, the customer must exercise it themselves.
4.7. PLAN-B NET ZERO ENERGY may check the creditworthiness of a new customer via an external service provider in compliance with data protection requirements.
4.8. The contract is concluded as soon as PLAN-B NET ZERO ENERGY confirms the order. The order confirmation is sent in text form by email before the start of the electricity supply and contains the information essential to the conclusion of the contract, in particular the supplied point of consumption and the meter number, if available. After conclusion of the contract, the customer receives a summary of the most important contractual terms.
4.9. PLAN-B NET ZERO ENERGY may reject switching requests if the customer has already been supplied by PLAN-B NET ZERO ENERGY twice within the last twelve months with a minimum contract term of one month each.
4.10. Unless these GTC expressly require text form by email, declarations may also be made in other text form, for example by letter or fax. The email address of PLAN-B NET ZERO ENERGY is kunde@planbnetzero-energy.com.
4.11. Emails from PLAN-B NET ZERO ENERGY are sent to the email address provided by the customer. The customer is obliged to keep their stored email address up to date and to report changes without delay. In individual cases, PLAN-B NET ZERO ENERGY may also send notifications by post.
4.12. The customer agrees to receive contractual communication in electronic form, unless mandatory statutory provisions require a different form.
4.13. When communicating by email, complete security of data transmission cannot be guaranteed. Documents are currently sent unencrypted.
5. Can the customer withdraw from the contract?
5.1. A consumer may withdraw from the contract within fourteen days of conclusion of the contract without giving reasons. The withdrawal instructions sent with the order confirmation are authoritative.
6. What happens when changing supplier? When does the electricity supply begin?
6.1. PLAN-B NET ZERO ENERGY carries out a possible change of supplier promptly and free of charge, in compliance with the statutory regulations and contractually agreed deadlines.
6.2. In the event of a change of supplier, PLAN-B NET ZERO ENERGY confirms to the customer in text form without delay whether and on which date the requested supply can commence.
6.3. The electricity supply begins on the date stated in the contract confirmation, but no earlier than the point at which all necessary questions regarding grid access, metering point operation and the takeover of the customer have been resolved, the previous supplier has confirmed the termination and the local grid operator has confirmed the start of grid usage.
6.4. The start of supply depends in particular on the termination of the previous supply contract, the absence of a disconnection of the connection, the confirmation of grid usage by the grid operator and the metering processes. PLAN-B NET ZERO ENERGY informs the customer of the start of supply.
6.5. If PLAN-B NET ZERO ENERGY is in fact unable to commence the electricity supply on the date stated in the contract confirmation, supply continues to be provided by the previous supplier or, due to statutory obligations, by the default supplier.
6.6. PLAN-B NET ZERO ENERGY is not obliged to commence the energy supply if the connection is disconnected at the scheduled start of supply or if there is no grid connection.
7. May the customer operate their own generation systems?
7.1. For the duration of the contract, the customer is obliged to purchase their entire electricity requirement for the respective point of supply from PLAN-B NET ZERO ENERGY. Excluded from this is coverage of demand by the customer's own combined heat and power systems of up to 50 kW electrical output, by systems using renewable energy, and by emergency generators that serve exclusively to secure electricity demand in the event of an interruption of the power supply.
Statutory rights of the customer to purchase or sell other electricity services not covered by the electricity supply contract, and to participate in legally permissible models for the shared use of electrical energy, remain unaffected.
8. How is the electricity supply remunerated?
8.1. The electricity price consists of a base price and a unit price. The amount is agreed when the contract is concluded. If an effective price change pursuant to Section 10 occurs, the changed price replaces the previously agreed price.
8.2. The customer is obliged to pay for the electricity supplied and consumed.
9. Which costs are included in the electricity price?
9.1. Unless stated otherwise in the price sheet or tariff conditions, the electricity price includes in particular the following costs: procurement and sales costs including billing costs, VAT, electricity tax, concession fee, grid fees, fees of the metering point operator for metering point operation, metering and billing, as well as statutory levies and charges in the version applicable at the time.
10. May PLAN-B NET ZERO ENERGY change prices?
10.1. Price changes by PLAN-B NET ZERO ENERGY are made at reasonable discretion pursuant to Section 315 of the German Civil Code (BGB), taking into account the following provisions.
10.2. PLAN-B NET ZERO ENERGY is entitled and obliged to adjust the contractually agreed prices insofar as the costs relevant to pricing change after conclusion of the contract. These costs include in particular energy procurement and marketing costs, balancing and balancing energy costs, grid fees, fees for metering point operation and metering, taxes, levies and charges, costs arising from statutory or regulatory requirements, and sales costs including the costs of customer service and billing. Price adjustments may also be made during an agreed minimum contract term, provided no expressly agreed price guarantee precludes this and the requirements of this Section 10 are met.
10.3. Cost increases may lead to an increase in prices. Cost reductions must be taken into account in favour of the customer according to the same standards. PLAN-B NET ZERO ENERGY will offset cost increases and cost reductions against each other and only take into account changes that have actually occurred.
10.4. The customer may have the fairness of the respective price change reviewed by a civil court.
10.5. Price changes are communicated to the customer in text form at least one month before they are scheduled to take effect.
10.6. If PLAN-B NET ZERO ENERGY changes the prices, the customer has the right to terminate the contract without notice with effect from the date on which the price change takes effect. PLAN-B NET ZERO ENERGY will expressly inform the customer of this in the notice of change. The termination must be made in text form. PLAN-B NET ZERO ENERGY will confirm the termination in text form, stating the end of the contract, without delay and at the latest within one week of receipt. The right to ordinary termination remains unaffected.
10.7. Changes in VAT as well as new, changed or abolished statutory charges, levies, grid fees or other price components set by public authorities may be passed on to the customer in the amount actually incurred, insofar as this is permitted by law.
11. How is the electricity supplied measured?
11.1. The electricity supplied is determined by the metering equipment in accordance with the provisions of the German Metering Point Operation Act (Messstellenbetriebsgesetz).
12. How is the electricity supplied read?
12.1. To determine the electricity supplied, PLAN-B NET ZERO ENERGY is entitled to use the meter readings transmitted by the local grid operator, metering point operator or metering third party.
12.2. Where metering is carried out with a smart metering system, the values provided for by law are to be used as a priority. PLAN-B NET ZERO ENERGY states in the invoice how any meter reading used was determined.
12.3. PLAN-B NET ZERO ENERGY may read the metering equipment itself or, insofar as permitted by law, require the customer to read it and transmit the readings if this is necessary for billing purposes, on the occasion of a change of supplier, or where there is a legitimate interest in verifying the reading. Statutory requirements on the priority use of remotely transmitted consumption data remain unaffected.
12.4. The customer may object to a self-reading in an individual case if it is unreasonable. In the event of a justified objection, PLAN-B NET ZERO ENERGY may not charge a separate fee for carrying out its own reading.
12.5. The customer is obliged to grant the authorised representative of the grid operator, the metering point operator or PLAN-B NET ZERO ENERGY, who carries identification, access to the property and premises for the purpose of reading the meter. The customer will be notified at least one week in advance; at least one alternative appointment must be offered.
12.6. If the meter reading cannot be determined, or if the customer does not carry out an agreed self-reading or does so late, PLAN-B NET ZERO ENERGY may estimate the consumption, taking appropriate account of the actual circumstances.
13. How are electricity and bonuses billed?
13.1. As a rule, PLAN-B NET ZERO ENERGY bills the electricity supplied once a year after the electricity supplied has been read or determined. The billing period may not significantly exceed twelve months. The customer receives the invoice no later than six weeks after the end of the billing period. After termination of the supply relationship, the customer receives the final invoice no later than six weeks.
13.2. Instead of annual billing, the customer may request monthly, quarterly or half-yearly billing in the customer portal. In the case of billing during the year, the customer is obliged to read the required meter readings themselves and to transmit them to PLAN-B NET ZERO ENERGY unprompted in text form by email by the communicated billing dates. If they are not transmitted in time, PLAN-B NET ZERO ENERGY is entitled to estimate the values.
13.3. PLAN-B NET ZERO ENERGY may request instalments for electricity consumption. The amount of the instalments is calculated proportionately based on consumption in the most recently billed period. If this is not possible, the calculation is based on the average consumption of comparable customers. If the customer credibly demonstrates that their consumption is considerably lower, PLAN-B NET ZERO ENERGY will take this into account appropriately.
13.4. The customer agrees to the electronic transmission of invoices, billing information and final invoices. Billing information is based on the consumption determined.
13.5. On request, the customer receives the invoice and billing information once a year free of charge in paper form. Supplementary information on the consumption history since the start of the contract is provided on request, where available.
13.6. If the invoice shows a credit balance in favour of the customer, PLAN-B NET ZERO ENERGY will refund it within two weeks or offset it against the next instalment payment.
13.7. If prices change within a billing period, the consumption relevant to the new prices is calculated pro rata temporis. Seasonal fluctuations in consumption are to be taken into account appropriately on the basis of empirical values of comparable customers. The same applies to changes in VAT and other cost components. Instalment payments may be adjusted accordingly.
13.8. PLAN-B NET ZERO ENERGY may grant the customer a bonus as part of certain tariffs or time-limited promotions. A bonus is not part of the agreed electricity price and does not constitute consideration for the electricity supply, but a voluntary additional benefit in accordance with these GTC and the respective tariff conditions.
13.9. If the customer has been promised a percentage bonus or a fixed bonus amount in euros that does not fall under the following paragraphs, it is granted after the end of the first year of supply. It is granted by way of a credit in the annual consumption bill and is offset in favour of the customer against the total costs of the electricity actually consumed.
13.10. If an instant bonus has been agreed, it becomes due at the contractually specified time in the promised amount and is paid out to the customer, provided the expressly agreed conditions for this are met.
13.11. If a first-year discount or an instalment bonus has been agreed, the customer receives a percentage discount in the promised amount on the total costs of the actual electricity consumption within the first year of supply. PLAN-B NET ZERO ENERGY is entitled to reduce the monthly instalment payments during the first year of supply by the corresponding percentage. The final calculation and offsetting take place in the annual consumption bill on the basis of actual consumption.
13.12. There is no entitlement to a new customer bonus if the contractual relationship is terminated before the end of one year of supply by the customer or for reasons for which the customer is responsible, or if the customer has already been supplied by PLAN-B NET ZERO ENERGY at the same point of consumption within the last six months before the new order.
13.13. If the customer moves house during the first year of supply and supply is continued at the new point of withdrawal in accordance with Section 22, periods of supply already completed are credited towards the first year of supply. No new year of supply begins for the purposes of calculating the bonus. The move does not give rise to an entitlement to an additional new customer bonus.
13.14. There is only an entitlement to payment of an instant bonus if the conditions agreed in the respective tariff are met. Where agreed in the tariff, payment requires that the contractual relationship has not been terminated at the agreed time of payment. Furthermore, there is no entitlement if the customer has already been supplied by PLAN-B NET ZERO ENERGY at the same point of consumption within the last six months before the new order. Mandatory statutory rights of the customer remain unaffected.
13.15. First-year discounts or instalment bonuses already granted must be repaid if the conditions for granting them subsequently cease to apply.
13.16. Offsetting a bonus against claims of PLAN-B NET ZERO ENERGY arising from instalment payments or invoices is excluded before the first annual consumption bill has been issued, unless these GTC provide otherwise.
14. When are invoices and instalments due?
14.1. Invoices and instalments become due at the time specified by PLAN-B NET ZERO ENERGY, but no earlier than two weeks after receipt of the request for payment.
14.2. The customer may only offset claims of PLAN-B NET ZERO ENERGY against undisputed or legally established counterclaims. This does not apply to counterclaims that the customer is entitled to offset under statutory provisions.
15. How can the customer pay?
15.1. The customer can choose between payment by granting a SEPA Core Direct Debit mandate and a bank transfer, at the customer's expense, to a bank account of PLAN-B NET ZERO ENERGY.
15.2. If the customer account or bank account has insufficient funds, if incorrect bank details have been provided, or if the customer does not transfer a due instalment on time, PLAN-B NET ZERO ENERGY is entitled to charge a fee covering the costs actually incurred for the return debit or for tracing the payment. The return debit fee is independent of the amount of the claim.
16. What applies in the event of late payment?
16.1. If the customer is in arrears with payments in the amount of one monthly instalment for more than two months, or with two or more monthly instalments, PLAN-B NET ZERO ENERGY may charge a flat rate for the costs incurred in structurally comparable cases when issuing a renewed request for payment or when collecting payment through an authorised agent. The flat rate must be easy to understand and may not exceed the costs to be expected in the ordinary course of events. At the customer's request, the basis of calculation must be provided.
16.2. Repeated late payment despite a warning letter in which termination without notice was announced in advance constitutes a material breach of contract and entitles PLAN-B NET ZERO ENERGY to terminate the contract without notice.
16.3. Otherwise, PLAN-B NET ZERO ENERGY is entitled to have the supply interrupted in accordance with Section 20.
17. What applies in the event of calculation errors?
17.1. If a test of the metering equipment reveals that the permissible error limits have been exceeded, or if errors are found in the determination of the invoice amount, any overpayment must be refunded by PLAN-B NET ZERO ENERGY or any shortfall paid by the customer. If the extent of the error cannot be determined with certainty, the consumption is estimated; the actual circumstances must be taken into account appropriately.
17.2. Claims under Section 17.1 are limited to the reading period preceding the discovery of the error, unless the effect of the error can be determined over a longer period. In this case, the claim is limited to a maximum of three years.
18. What happens in the event of a disruption?
18.1. If an interruption or irregularity in the power supply arises due to a disruption of grid operation, including the grid connection, the customer may have claims against the grid operator under the statutory provisions. PLAN-B NET ZERO ENERGY is released from its obligation to perform insofar as the interruption or irregularity is the result of such a disruption.
18.2. On request, PLAN-B NET ZERO ENERGY informs the customer of the reasons for an interruption or irregularity caused by the grid operator, insofar as these are known or can reasonably be clarified.
18.3. For cases of damage not covered by Section 18.1, the liability of PLAN-B NET ZERO ENERGY and its vicarious agents and assistants for culpably caused damage is limited to intentional and grossly negligent conduct. This does not apply to damage resulting from injury to life, body or health, or from the culpable breach of material contractual obligations. The provisions of the German Product Liability Act and the German Liability Act remain unaffected.
19. When is PLAN-B NET ZERO ENERGY released from its obligation to supply?
19.1. PLAN-B NET ZERO ENERGY is not obliged to commence the energy supply if the customer's connection is disconnected at the scheduled start of supply or if there is no grid connection.
19.2. PLAN-B NET ZERO ENERGY is released from its obligation to supply if and for as long as the grid connection, grid usage or connection usage has been interrupted by the grid operator in accordance with the relevant statutory provisions.
19.3. The same applies if and for as long as the grid connection, grid usage or connection usage has been interrupted by the grid operator for other reasons for which PLAN-B NET ZERO ENERGY is not responsible. This also applies to the consequences of a disruption of metering point operation.
19.4. PLAN-B NET ZERO ENERGY is released from its obligation to supply if and for as long as PLAN-B NET ZERO ENERGY is prevented from procuring or supplying electricity in accordance with the contract by force majeure or other circumstances that PLAN-B NET ZERO ENERGY cannot eliminate or whose elimination is not economically reasonable.
19.5. Force majeure is any external event with no operational connection that is unforeseeable and unavoidable even with the utmost care that can reasonably be expected.
19.6. PLAN-B NET ZERO ENERGY is entitled to extraordinary termination if the economic framework conditions of the supply change significantly after conclusion of the contract and continuing the contract becomes economically unreasonable despite permissible price adjustments pursuant to Section 10.
20. When is PLAN-B NET ZERO ENERGY entitled to interrupt the supply?
20.1. PLAN-B NET ZERO ENERGY is entitled to have the customer's supply interrupted by the grid operator without prior warning if the customer culpably breaches a contractual provision to a not insignificant extent and the interruption is necessary to prevent the use of energy by circumventing, manipulating or bypassing the metering equipment or before it has been installed.
20.2. PLAN-B NET ZERO ENERGY may threaten the interruption of supply together with the reminder, provided this is not disproportionate to the severity of the breach.
20.3. Together with the warning, PLAN-B NET ZERO ENERGY informs the customer of ways to avoid the interruption of supply that do not incur additional costs.
20.4. The customer will be notified of the start of the interruption of supply at least one week in advance.
20.5. An interruption due to late payment is only possible if the statutory requirements are met, in particular if the customer is in arrears with payment obligations in the legally relevant amount and the arrears amount to at least 100 euros.
20.6. PLAN-B NET ZERO ENERGY will have the supply restored without delay as soon as the reasons for the interruption no longer apply and the customer has reimbursed the costs of interrupting and restoring the supply. The costs may be charged as a flat rate for structurally comparable cases. The customer is free to prove that no damage or less damage has occurred.
21. How long does the contract run and how can it be terminated?
21.1. The contract runs for an indefinite period and may be terminated by the customer or PLAN-B NET ZERO ENERGY at any time with one month's notice in text form (ordinary termination). The notice period begins upon receipt of the termination by the respective contracting party.
21.2. A change to a different tariff during an agreed minimum contract term is only possible by mutual agreement. Statutory termination rights and special termination rights of the customer remain unaffected.
21.3. If the customer wishes to terminate because they have chosen a different supplier, they can instruct the new supplier to handle the termination. If the customer wishes to terminate without a new supplier, the termination must be addressed to PLAN-B NET ZERO ENERGY in text form.
21.4. A termination always requires text form. Sending it in writing by post is not required, but possible.
21.5. PLAN-B NET ZERO ENERGY confirms a termination by the customer by email, stating the end of the contract, without delay and at the latest within one week of receipt.
21.6. The right to terminate without notice for good cause pursuant to Section 314 of the German Civil Code (BGB) remains unaffected. Good cause exists in particular in the event of a repeated, not insignificant breach of material contractual obligations despite a reminder, in particular in the event of late payment.
21.7. In the event of termination without notice by the customer, it is advisable, in order to speed up the processing of the change of supplier, to inform the new supplier that the termination is without notice.
22. What happens if the customer moves house?
22.1. In the event of a move, the customer undertakes to notify PLAN-B NET ZERO ENERGY in text form, no later than six weeks before moving out, of the move-out date, the new supply address, the new billing address, the move-in date and, if known, the new meter number.
22.2. Together with the notification, but no later than six weeks before moving out, the customer may terminate the contract for supply at the previous point of withdrawal without notice with effect from the notified move-out date or with effect from a later date.
22.3. In the event of a move, PLAN-B NET ZERO ENERGY checks whether supply is possible at the new point of withdrawal. If supply is possible, PLAN-B NET ZERO ENERGY may offer supply on the previous contractual terms or on the tariff conditions valid at the time of the move. The customer will be informed of the result of the check within two weeks.
22.4. The customer's termination without notice does not take effect if PLAN-B NET ZERO ENERGY informs the customer within two weeks of receiving the extraordinary termination that supply at the new point of withdrawal is possible on the previous contractual terms.
22.5. If PLAN-B NET ZERO ENERGY offers the customer supply at the new point of withdrawal on changed tariff conditions, this requires a corresponding agreement. If the customer does not accept the offer, an effectively declared extraordinary termination pursuant to Section 22.2 remains unaffected.
22.6. If the customer culpably breaches their notification obligations under this Section 22 and PLAN-B NET ZERO ENERGY suffers damage as a result that is compensable under the statutory provisions, the customer is obliged to compensate for this damage in accordance with the statutory provisions.
23. Can these GTC change?
23.1. If PLAN-B NET ZERO ENERGY wishes to change these GTC, the amended GTC will be offered to the customer in text form by email at least six weeks before the date on which the new GTC are to take effect.
23.2. The proposed changes only take effect if the customer accepts them, where applicable by way of the deemed consent regulated below.
23.3. The customer's silence is only deemed acceptance of the offer of change if the offer of change is made in order to restore the conformity of the contractual provisions with a changed legal situation, in particular due to a change in the law, a final court decision or a binding official order, and the customer does not reject the offer of change before the proposed date on which it is to take effect. PLAN-B NET ZERO ENERGY will inform the customer of the consequences of their silence in the offer of change.
23.4. Deemed consent does not apply to changes to main performance obligations, including prices, to changes that are equivalent to the conclusion of a new contract, or to changes that would significantly shift the previously agreed balance between performance and consideration in favour of PLAN-B NET ZERO ENERGY. In these cases, PLAN-B NET ZERO ENERGY will obtain the customer's consent in another way.
23.5. If PLAN-B NET ZERO ENERGY makes use of deemed consent, the customer may terminate the contract affected by the change without notice and free of charge before the proposed date on which the changes are to take effect. PLAN-B NET ZERO ENERGY will draw particular attention to this right of termination.
24. What happens in the event of a dispute?
24.1. The place of jurisdiction is the respective place where the customer takes delivery of the electricity, insofar as permitted by law.
24.2. For questions and complaints regarding the electricity supply, the customer, as a consumer within the meaning of Section 13 of the German Civil Code (BGB), may contact PLAN-B NET ZERO ENERGY GmbH, Mühlheimer Tor -Dieselstr. 2, 63165 Mühlheim am Main, Germany.
24.3. To settle disputes, private customers may apply for arbitration proceedings at the Schlichtungsstelle Energie e.V. (Energy Arbitration Board). The prerequisite is that no mutually satisfactory solution has been found between the customer and customer service. PLAN-B NET ZERO ENERGY is obliged to participate in the arbitration proceedings.
24.4. The Schlichtungsstelle Energie e.V. can be reached at:

26. Does PLAN-B NET ZERO ENERGY offer an app with a premium subscription?
26.1. PLAN-B NET ZERO ENERGY provides the customer with an app. Use of the app is free of charge for the customer.
26.2. Within the app, the customer can optionally take out a paid premium subscription. With the premium subscription, the customer receives additional services, the scope and price of which are set out in the current service description in the app.
26.3. The premium subscription runs for an indefinite period and can be cancelled by the customer on a monthly basis. Cancellation can be declared in text form or via the corresponding function in the app and takes effect at the end of the current billing month.

General Terms and Conditions
PLAN-B NET ZERO ENERGY GmbH
As of: 05/2026
§ 1 Scope of Application, Definitions
1) Scope of Application
These General Terms and Conditions ("GTC") govern the supply of electrical energy to household customers by PLAN-B NET ZERO ENERGY GmbH, Dieselstraße 2, 63165 Mühlheim am Main ("PBNZE", "we"), for the contractually agreed supply point, outside of basic and substitute supply, within the framework of a special customer contract.
A household customer is an end consumer who primarily purchases energy for self-consumption in the household ("Customer", "you").
The electricity supply contract is subject to the condition that:
- the customer's annual electricity consumption is below 50,000 kilowatt-hours (kWh) per billing year
- none of the following metering devices are used:
- Metering device with recording interval metering
- Dual-tariff meter with reduced grid fees
- Meter with a temperature-dependent load profile
- Customer's metering point in a foreign control area
2) Rate Plan
The rate plan applicable to the customer is determined by the offer presented during the ordering process.
3) Authorization
Upon conclusion of the contract, the customer authorizes PBNZE to register with the local grid operator and to terminate an existing contract for the specified supply point with the previous supplier. The customer will provide PBNZE with the necessary contract data for this purpose.
4) Smart Metering System
If the customer has given their consent to the ordering of a smart metering system (Section 2 No. 7 Metering Point Operation Act – "MsbG") at the time of contract conclusion or at a later date, PBNZE is entitled to request or initiate the early installation of a smart metering system at the metering point from the responsible metering point operator. The costs incurred for this will be passed on by PBNZE to the customer in corresponding application of Sections 4(5) and 5.
The costs are determined by the current version of the MsbG in conjunction with the price list of the responsible metering point operator. The costs applicable at the time of contract conclusion will be communicated to the customer on the PBNZE website and the PBNZE app, as well as in the contract confirmation. In the event of an order for a smart metering system after contract conclusion, the customer will receive a corresponding amendment confirmation ("Änderungsbestätigung").
5) Amendment of the General Terms and Conditions
PBNZE is entitled to amend these General Terms and Conditions if, after conclusion of the contract, unforeseeable changes occur that were not initiated by PBNZE and over which PBNZE has no influence, and if these changes significantly disturb the equivalence of performance and consideration.
Changes in this sense may be caused in particular by:
- new or amended legal bases
- new case law
- new or amended determinations or other decisions by the Federal Network Agency or other authorities
PBNZE will only amend the General Terms and Conditions if and to the extent that the amendment is necessary to restore the equivalence of performance and consideration or if regulatory gaps cause significant difficulties in contract execution.
PBNZE will notify the customer of the respective changes in text form at least one month before their planned effective date. The customer has the option to object to the changes in text form at the time of their planned effective date. Timely dispatch of the objection is sufficient to meet the deadline. If the customer does not object or does not object in due time, the changes are deemed approved.
In addition, the customer may terminate the contract in text form without notice at the time of the planned effective date. PBNZE will specifically inform the customer of the consequences of a failure to object and of the right to terminate the contract without notice when changes are announced.
Changes to the electricity price are made exclusively in accordance with Sections 4 and 5.
§ 2 Conclusion of Contract
1) Formation of the Contract
a) The presentation and promotion of PBNZE's services on the PBNZE website (www.planbnetzero-energy.com) and/or in the PBNZE app does not constitute a binding offer to enter into a contract, but is merely an invitation for the customer to submit an offer to PBNZE (so-called invitatio ad offerendum).
b) The customer can submit a binding offer to conclude an electricity supply contract by clicking the button with the text "Conclude contract with obligation to pay" on the PBNZE website and in the PBNZE app, providing all essential data. Until the offer is submitted, the customer can review their information in the online form at any time and, if necessary, correct it using the back buttons.
c) PBNZE will electronically confirm receipt of the offer and accept the customer's offer ("Acknowledgement of Receipt and Contract Confirmation"). The electricity supply contract is concluded upon receipt of the Acknowledgement of Receipt and Contract Confirmation. PBNZE will subsequently inform the customer of the start date of delivery in a separate communication. PBNZE allows the customer to pay for the supply of electricity and other services using insecure payment methods (invoice and SEPA direct debit). PBNZE therefore reserves the right to check the customer's creditworthiness before confirming the contract.
2) Ordering a smart metering system after contract conclusion
In the event of ordering a smart metering system after the conclusion of the electricity supply contract (see § 1(4)), the agreement on the amendment of the electricity supply contract ("Amendment Agreement") is concluded as follows:
a) The customer can declare their consent to order a smart metering system by clicking the checkbox on the PBNZE website and in the PBNZE app, and submit a binding offer to conclude the amendment agreement by clicking the button with the text "Conclude contract with obligation to pay". Until the offer is submitted, the customer can review their consent at any time and, if necessary, correct it by unchecking the box or cancel the ordering process.
b) PBNZE will electronically confirm receipt of the offer ("Acknowledgement of Receipt") with a copy of these General Terms and Conditions. The Acknowledgement of Receipt does not yet constitute acceptance of the offer by PBNZE. The amendment agreement is only concluded and the change to the electricity supply contract comes into effect upon receipt of the amendment confirmation.
3) Supplier Change
In the event of a supplier change, a prerequisite for the start of supply is that PBNZE receives confirmation from the previous supplier regarding the termination of the customer's previous electricity supply relationship.
4) Storage of Contract Text
The contract text (acknowledgement of receipt with the respective valid General Terms and Conditions and contract confirmation or amendment confirmation) will be stored by PBNZE after the contract is concluded and transmitted to the customer, but will no longer be accessible online to the customer.
5) Start of Supply
Delivery typically begins in accordance with the regulations for supplier changes, no later than three weeks after the grid usage registration is received by the grid operator responsible for the customer, but not before the termination of the previous electricity supply contract. The customer may also specify a preferred start date for delivery in their order. If the desired date is not feasible, delivery will commence on the earliest possible date.
6) Grid Operator Liability
In the context of supplier switching processes, the grid operator is not an auxiliary agent of PBNZE, and PBNZE is not liable for an incorrect registration confirmation by the grid operator.
7) Point of Delivery
PBNZE is obliged to provide electricity at the customer's electricity meter (point of delivery).
8) Power of Attorney for Representation
If a third party acts in the name or on behalf of the customer, PBNZE reserves the right to revoke the contract unless the customer sends a power of attorney to kunde@planbnetzero-energy.com upon request by PBNZE.
9) Contract Language
The contract language is German.
§ 3 Statutory Right of Withdrawal
1) Right of Withdrawal for Consumers
If the customer is a consumer (§ 13 BGB), they are entitled to a right of withdrawal in accordance with statutory provisions. The right of withdrawal applies to both the electricity supply contract and the amendment agreement, provided that the conditions specified below are met in each case. The consequences of withdrawal are limited to the electricity supply contract or the amendment agreement for which the customer exercises the right of withdrawal.
2) Instructions on Withdrawal
The right of withdrawal is subject to the regulations detailed in the following instructions on withdrawal:
Instructions on Withdrawal
You have the right to withdraw from this contract within fourteen days without giving any reason.
The withdrawal period is fourteen days from the day the contract is concluded.
To exercise your right of withdrawal, you must inform us (PLAN-B NET ZERO ENERGY GmbH, Dieselstraße 2, 63165 Mühlheim am Main, E-Mail: kunde@planbnetzero-energy.com) of your decision to withdraw from this contract by means of a clear statement (e.g., a letter sent by post or an email).

Section 4 Electricity Price
1) Payment Obligation
The customer is obliged to pay for the electrical energy consumed.
2) Price Components
The electricity price includes the following components:
- a) the spot market price (see 3))
- b) the other price components, including the PBNZE fee (see 6))
3) Spot Market Price
The spot market price (ct/kWh) corresponds to the spot market prices of EPEX Spot SE. EPEX Spot SE is the European exchange for short-term electricity trading. Among other things, EPEX Spot SE operates the Day-Ahead electricity market in Germany. There, once a day, prices for each hour of the following day are determined and published in EUR per MWh.
The determined prices can be viewed on:
- the website of EPEX Spot SE: https://www.epexspot.com/en/basics-powermarket
- the website www.planbnetzero-energy.com
- in the PBNZE app
The price determined in this way for each individual hour of the following day is passed on to the customer.
For clarification: The spot market price is adjusted automatically, and PBNZE has no discretion regarding changes to spot market prices.
Risk Notice: PBNZE expressly informs the customer that the prices applicable for each hour of a day are not fixed in advance but change hourly depending on spot market prices. This presents both opportunities and risks for the customer compared to an electricity supply contract with a fixed price.
Spot market prices can thus fall below the prices of fixed-price offers available on the market, which can lead to (significant) savings in electricity procurement costs for the customer. However, spot market prices can also exceed the fixed prices for electricity supply offered on the market. In the latter case, the customer has no protection against electricity costs that may significantly exceed the price level of comparable fixed-price contracts.
4) Hourly Billing
If the customer has a smart metering system according to § 2 No. 7 MsbG, a free metering system according to § 2 No. 13 MsbG, or any other technical device that enables hourly transmission of the customer's consumption (collectively referred to as "SmartMeter"), hourly allocation will be based on the actual energy consumption in the respective hour.
In the case of a smart metering system according to § 2 No. 7 MsbG, this only applies if the metering point operator PBNZE provides the hourly meter readings in an appropriate form. For a free metering system according to § 2 No. 13 MsbG or any other technical device, hourly allocation of consumption is only possible if the respective metering system or technical device is integrated into PBNZE's system. The metering systems and technical devices integrated into PBNZE's system are available on the website www.planbnetzero-energy.com.
If the customer's electricity consumption is measured with a conventional metering device or a modern metering device according to § 2 No. 15 MsbG without transmitting hourly values, or if hourly measurement of the customer's electricity consumption is not possible for other legal or factual reasons, the hourly spot market prices determined according to paragraph (3) will be assigned to the energy consumption based on the standard load profile applicable to the customer.
Should a permanent switch from hourly billing to billing based on the applicable standard load profile become necessary during the contract term for legal or factual reasons, PBNZE may make a corresponding switch to billing based on the applicable standard load profile. For the notification by PBNZE and the customer's right of termination, § 5(3) sentences 2 to 6 apply accordingly.
5) Smart Metering System for Hourly Billing
Insofar as there is a legal claim to the installation of a smart metering system within a legally defined period, PBNZE may demand that the customer agrees to PBNZE asserting this legal claim, provided that their consumption is billed hourly without a smart metering system (§ 2 No. 7 MsbG).
If the customer refuses consent or if the claim is not fulfilled by the responsible metering point operator within the statutory period, PBNZE may switch the billing of electricity consumption to the currently valid standard load profile. For the notification of the switch to billing according to the standard load profile by PBNZE and the customer's right of termination, § 5(3) sentences 2 to 6 apply accordingly.
As long as hourly recording of energy consumption is not possible, potential savings from billing spot market prices according to paragraph (3) cannot be fully realized or cannot be realized at all.
6) Other Price Components
In addition to the spot market prices mentioned in section (3), the electricity price includes PBNZE's additional procurement costs (e.g., for the procurement of guarantees of origin for the supply of electricity generated from renewable energy) as well as the PBNZE fee.
In addition, the other price components consist of:
- Grid usage fees
- Fee for metering point operation, including any additional services ordered (unless this is part of a separate contract between the customer and a metering point operator)
- Value-Added Tax
- Electricity Tax
- Concession Fee
- Levies pursuant to Sections 12, 2 No. 17 of the Energy Financing Act (EnFG, CHP Surcharge and Offshore Surcharge)
- Levy pursuant to Section 19 (2) of the Electricity Grid Charges Ordinance (StromNEV)
Section 5 Changes to Other Price Components
1) Price Adjustments
If the other price components change according to Section 4(6), the electricity price for the customer will be adjusted accordingly. Changes to the other price components by PBNZE are made by unilateral determination of performance in the exercise of equitable discretion. The price change is subject to an equity review pursuant to Section 315 (3) of the German Civil Code (BGB). The customer has the right to have the price change reviewed by a civil court.
When PBNZE unilaterally determines performance, only cost changes that are relevant for calculating the other price components shall be taken into account.
- In the event of an increase in the other price components, PBNZE is entitled to increase the electricity price and pass on the cost increase accordingly.
- In the event of a decrease in the other price components, PBNZE is obliged to reduce the electricity price and pass on the cost reduction accordingly.
If the changes have both cost-reducing and cost-increasing effects, PBNZE will carry out an offset, so that depending on the proportion of cost-reducing and cost-increasing price components, an electricity price increase or decrease, or possibly even an unchanged electricity price, may result.
2) Equal Treatment of Increases and Decreases
PBNZE must determine the scope and timing of a price change in such a way that both increases and decreases in the other price components are taken into account according to the same objective and temporal criteria. In particular, PBNZE is obliged not to allow a longer period between the review of cost development and the implementation of a price change for cost reductions than for cost increases.
3) Information and Right of Termination
PBNZE will inform the customer of the intended change to the other price components at least one month before it takes effect. In the event of a change, the customer may terminate the contract without notice at the time the change is scheduled to take effect. The termination must be in text form. PBNZE will specifically inform the customer of the right to terminate in the information letter regarding the price change. The right to ordinary termination pursuant to Section 8(3) remains unaffected.
4) New Taxes and Levies
Paragraphs 1) to 3) also apply insofar as new taxes, levies or other state-imposed surcharges or reliefs affecting the procurement, generation, storage, grid usage (transmission and distribution), metering point operation or consumption of electrical energy become effective in the future.
5) Value Added Tax
Notwithstanding paragraphs 1) to 3), changes in VAT according to the Value Added Tax Act will be passed on to the customer at the time the change becomes effective, without prior notice and without the possibility of extraordinary termination.
§ 6 Liability, Statutory Warranty Rights
1) Exclusion of Liability for Grid Disruptions
In the event of an interruption or irregularities in the electricity supply, PBNZE is exempt from its performance obligations insofar as these are consequences of a disruption to grid operation, including the grid connection, or a disruption to metering point operation. Sentence 1 does not apply if the interruption is due to unauthorized actions by PBNZE or if PBNZE is responsible for the interruptions or irregularities.
PBNZE is obligated to promptly provide the customer, upon request, with information regarding the facts related to damages caused by the grid operator or metering point operator, to the extent that these facts are known to PBNZE or can be reasonably clarified by PBNZE.
The competent party for any customer claims, according to the Low Voltage Connection Ordinance (NAV), is the responsible distribution grid operator to whose grid the customer is connected.
2) Claims against Grid Operators
In the event of an interruption or irregularities in the electricity supply as a result of a disruption to the grid connection, the customer may be entitled to claims against the grid operator, to whose grid the customer's supply point is connected, in accordance with statutory provisions. PBNZE will gladly provide the customer with the grid operator's contact information upon request, but is not obligated to provide further support in asserting such claims.
3) Limitation of Liability
Moreover, PBNZE's liability – irrespective of the legal grounds – is excluded if the damage is solely based on a slightly negligent breach of non-essential duties by PBNZE. Non-essential duties are those whose observance by PBNZE the customer cannot rely on.
Furthermore, the liability of PBNZE and its vicarious agents for slight negligence is limited to foreseeable and contract-typical damages.
Liability for personal injury, for assuming a guarantee, for fraudulently concealed defects, and liability under the Product Liability Act remains unaffected.
4) Warranty
Statutory warranty rights apply.
§ 7 Billing
1) Billing Period
Electricity consumption is billed monthly by PBNZE. If the customer does not have a SmartMeter or if hourly billing is permanently not possible for the reasons stated in § 4(4) or § 4(5), the hourly determined prices will be billed based on the consumption calculated from the previous year's values in conjunction with the applicable standard load profile until the first meter reading is taken.
If no previous year's values are available, consumption will be calculated based on the consumption behavior of a customer group typical for the customer. If the customer credibly demonstrates that their consumption is significantly lower, this must be appropriately taken into account in the assessment.
Furthermore, for customers without a SmartMeter or for customers for whom hourly billing is permanently not possible according to § 4(4) or § 4(5), a corrected invoice will be issued based on the meter reading transmitted by the metering point operator at least once a year. Upon customer request, the corrected invoice will be issued semi-annually, quarterly, or monthly.
Additionally, customers can report their consumption data to PBNZE via the PBNZE app. Provided these data are validated and confirmed by the metering point operator, they will be included in the billing.
2) Delivery of Invoices
Billing is carried out electronically. Upon customer request, invoices and billing information will be provided in paper form once a year free of charge.
If consumption data is not transmitted remotely, the customer receives billing data every six months, or every three months upon request. If consumption data is transmitted remotely, the customer receives consumption information monthly.
3) Final Billing
The final billing is based on the respective meter readings at the supply point at the end of each billing period as defined in paragraph (1). If the billing results in a credit balance for the customer, PBNZE must pay this out within two weeks.
4) Final Billing upon Contract Termination
Upon termination of the electricity supply contract, any credit balance resulting from a corrected invoice will be refunded immediately. Invoicing will take place no later than three weeks after the end of the billing period or after the termination of the supply relationship. Any credit balance must be paid out within two weeks.
5) Due Date
Invoices are due on the specified payment date, but no earlier than fourteen calendar days after receipt of the invoice.
6) SEPA Direct Debit Procedure
Invoice payments are made via SEPA direct debit. The customer grants PBNZE a corresponding direct debit mandate. PBNZE must inform the customer of the direct debit amount at least one day before execution. The customer is responsible for ensuring that their account has sufficient funds to meet their payment obligations under this contract. The customer must reimburse PBNZE for any costs incurred due to a chargeback for which the customer is responsible.
7) Bank Transfer
Instead of the SEPA direct debit procedure, the customer may choose to pay invoices by bank transfer. Transfers must be made to the account specified by PBNZE. The decisive factor for timely payment is the value date on PBNZE's account.
Section 8 Contract Term and Termination
1) Minimum Term
There is no minimum term for the contract.
2) Contract Duration
The contract runs for an indefinite period.
3) Ordinary Termination
The electricity supply contract can be terminated by either party in text form with four weeks' notice. Section 5(3) remains unaffected. PBNZE will confirm any customer termination, regardless of the legal reason, in text form within one week of receipt, stating the contract end date.
4) Termination upon Relocation
In the event of a relocation, the customer may terminate the contract with six weeks' notice, effective either upon moving out or at a later date, unless PBNZE offers the customer, within two weeks of receiving the termination notice in text form, a continuation of the supply contract at the new residence under the existing contract terms and supply is possible at the new consumption point.
The customer must notify PBNZE of the relocation in text form one month prior to the move, stating the new address and the specific move-out and move-in dates.
If PBNZE is unable to supply the new delivery point, it will inform the customer in text form. If the customer is unable to receive electricity at the new delivery point, they will inform PBNZE in text form.
5) No Termination Fees
PBNZE may not charge separate fees for contract termination, especially due to a supplier change.
§ 9 Extraordinary Termination
The contract may be terminated by either party for good cause without notice, in text form.
PBNZE is entitled to extraordinary termination, particularly if the customer repeatedly fails to meet payment obligations despite reminders, or fails to meet a payment obligation despite repeated reminders, and if the extraordinary termination was threatened at least two weeks in advance.
This does not apply if the consequences of the extraordinary termination are disproportionate to the severity of the breach or if the customer demonstrates to PBNZE's satisfaction that there is a sufficient prospect of them fulfilling their payment obligations.
§ 10 Data Protection
PBNZE processes the customer's personal data, including its collection, storage, and use, in accordance with legal regulations and the privacy policy available here.
§ 11 GHG Quota
Under the Greenhouse Gas Reduction Quota, or GHG quota for short, PBNZE customers who operate a charging station and own a registered electric vehicle can sell their GHG quota potential, linked to electric charging current, to companies subject to quota obligations via a third-party GHG service provider.
The details regarding the selection of the third GHG service provider are set out in the General Terms and Conditions of the GHG service provider cooperating with PBNZE. By registering with PBNZE for the GHG quota, personal data (name, email address) will be transmitted to the GHG service provider responsible for processing the quota sale.
§ 12 Statutory Information Obligations
1) Contact and Complaints
Customers can address questions regarding contracts, invoices, or electricity supply, or complaints, particularly concerning contract conclusion or the quality of PBNZE's services, to PBNZE via the PBNZE app, PBNZE's website, or by email (kunde@planbnetzero-energy.com) or post (PLAN-B NET ZERO ENERGY GmbH, Dieselstraße 2, 63165 Mühlheim am Main). PBNZE is obliged to respond to a complaint within four weeks of receipt.
2) Arbitration Procedure
To resolve disputes, the customer can apply for an arbitration procedure with the Energy Arbitration Board e.V.:
Energy Arbitration Board e.V.
Friedrichstraße 133
10117 Berlin
Phone: 030 2757240-0
Fax: 030 2757240-69
Email: info@schlichtungsstelle-energie.de
Website: www.schlichtungsstelle-energie.de
Such an application is only admissible if PBNZE has not remedied the consumer complaint within four weeks of receipt at the latest. PBNZE is obliged to participate in the arbitration procedure.
The right of the parties to appeal to the courts or to request another procedure under the EnWG remains unaffected. Submitting a complaint to the arbitration board suspends the statutory limitation period in accordance with Section 204 (1) No. 4 of the German Civil Code (BGB).
3) Online Dispute Resolution
The European Commission provides a platform for online dispute resolution (ODR) (available at: http://ec.europa.eu/consumers/odr/). PBNZE is neither obliged nor willing to participate in this dispute resolution procedure.
