Prices and terms of payment


Depending on the order, REETEC’s services shall in particular extend to

  • technical maintenance and electrical installation and assembly of wind turbines;
  • electrical wiring of wind farms usually on behalf of the operators, i.e. wiring of several wind turbines among each other and the grid connection;
  • mere sale of aviation obstruction markers;
  • sale of aviation obstruction markers plus installation, assembly and connection;
  • mechanical installation and assembly of wind turbines;
  • cleaning and assessment of rotor blades of wind turbines;
  • warranty analyses.


In detail, the following applies to prices and the payment terms:

The prices stated, unless otherwise agreed in writing are quoted ex-works or ex-distribution warehouse (EXW – Incoterms 2010); costs for packaging shall be charged sepa­rately according to actual expenditure. The prices do not include the statutory value added tax; it shall be indicated separately at the invoice date at the amount prevailing at the date of the invoice.

REETEC is entitled to increase its prices in line with its actual costs, if the information provided by the customer regarding the services to be provided were incorrect. If the costs increase (e.g. due to rising prices of our suppliers) or after the conclusion of the contract, freight, taxes, duties or charges are introduced or increased, REETEC shall be entitled to amend the price accordingly unless REETEC is responsible for the increase. The price increase shall take effect as soon as REETEC has notified the customer thereof in writing.

c)   Granting of discount shall only apply if this has expressly been agreed in writing. Otherwise deduction of discount shall be inadmissible and the customer is obliged to pay invoices without deduction by free of charge transactions to one of REETEC's bank accounts within 14 days after the invoicing date.

The customer may set off only if the counterclaims are legally established or undisputed. This applies to the same extent to the pursuit of rights of retention and the customer's right to refuse performance.

e)   If the customer falls into total or partial arrears with due payments in the meaning of lit. c) (payment within 14 days after the invoicing date) REETEC shall be entitled to with­draw from the contract after unsuccessful expiration of an adequate set deadline. The right of withdrawal shall also exist if circumstances suited to reducing the creditworthiness of the customer become known. If REETEC withdraws, REETEC shall be entitled to mark the goods supplied as property of REETEC, to store them seperately and have them collected at the expense of the customer. The customer already declares his consent by the fact that the people commissioned with the collection by REETEC may enter and drive on the premises where the goods are situated.

As an alternative to REETEC’s right of withdrawal pursuant to section e) above, REETEC can also demand that security be furnished by the customer.

If the parties so agree, REETEC may request the customer to store the spare parts at its own expense and risk prior to their installation.

5)  Reservation of ownership

a)   Goods supplied or installed by REETEC shall remain its property until the payment of the purchase price and all claims arising in the ongoing business relationship with the customer have been paid. The inclusion of individual claimes in a current account and account balance do not affect the reservation of ownership; Reservation of ownership is not affected by posting individual claims to an on-going account and drawing a balance; in this case, the reservation refers to the recognised or actual balance. Payment is only regarded as made, once REETEC recieves the countervalue or the sum is credited to our bank account. The reservation of ownership is not revived for a delivery item after the customer has acquired ownership to this delivery item and new claims from the business relationship are accrued against it.

If the customer is in breach of its obligations under the contract, in particular in case of default of payment, REETEC is entitled, in accordance with legal provisions, to withdraw from the contract and to take back the delivery item. The customer hereby irrevocably grants REETEC unhindered access to its business and storage premises for the purpose of taking back the goods. After taking back the goods, REETEC is authorised to exploit them. The exploitation revenue shall be offset against the customer's liabilities - less appropriate exploitation costs - as per section 367 BGB (German Civil Code).

c)   The customer is entitled to resell the goods in the ordinary course of business; this does not apply if it has been agreed in connection with the sale, that the claims of the customer against the third party expires by way of off-setting (e.g. according to sec. 387 German Civil Code) The above authorisation does not include the goods or any items made from it without the consent of REETEC to be transferred or pledged. Financing contracts (e.g. leasing) that include the transfer of REETEC’s retention rights require REETEC’s prior written consent unless the contract does not oblige the financing institution to pay the part of the purchase price that we are entitled to directly to REETEC. If the customer, according to the aforesaid is entitled to resell the goods, the customer already now assigns all claims to REETEC (including all balance claims arising even after termination of the current account) in the amount of the final invoice sum (including VAT) of REETEC´s claims against the customer which it accrues from the resale or other legal grounds against its buyer or a third party. The assignment applies irrespective of whether the goods are sold without or after processing. REETEC accepts the assignment. The customer shall remain empowered to collect said claims even after the assignment. This does not affect REETEC’s authorisation to collect the claims. REETEC however undertakes to not collect the claims as long as the customer meets his payment obligations from the proceeds received and does not fall into arrears with payments. However, if this is the case, REETEC may require that the customer discloses the assigned claims and their debtors, provides all details required for collection, in particular the address of the debtor, hands over the pertaining documents and informs the debtors about the assignment.

If the goods are processed by REETEC or the customer with other objects not belonging to REETEC, then REETEC shall acquire co-ownership of the new item in proportion to the value of the goods (the total invoice amount including VAT) with the other processed objects at the time they are processed. For the item produced in processing this clause 5 shall apply in all other respects.

e)   If the goods are being inseparably connected by the customer or REETEC with other objects not belonging to REETEC, REETEC shall acquire co-ownership of the new item in proportion to the value of the goods (the total invoice amount including VAT) to the value of the other connected objects at the time of the connection. If the goods are connected in such a way that the customer's item is to be considered as the main item, it shall be agreed that the customer already now shall transfer proportionate co-ownership to REETEC. REETEC accepts the transfer. The customer shall hold the sole ownership or co-ownership for REETEC free of charge.

6)  Delivery time / Delivery

a)  The ordered services and spare parts are to be delivered within the agreed lead times.

b)  Unless REETEC has not expressly agreed otherwise with the customer, the delivery lead times are not warranted. If REETEC can not deliver in time, REETEC immediately informs the customer. There is no liability of REETEC or a possibility for termination or withdrawal for the customer.

c)  The delivery is agreed to be ex-works (EXW - Incoterms 2010) unless the parties expressly agree to the contrary. If customer is in default of acceptance, REETEC is entitled to claim compensation for additional expenses (e.g. for storing the goods). If the customer violates other cooperation obligations, REETEC may claim compensation for any damage incurred unless the customer has not culpably infringed the cooperation obligations

Work and services that require on-site support by the customer are performed by REETEC on the site agreed to. The customer shall inform REETEC in good time before the provision of the contractual performances about all factors influencing the implementation of the contract.

e)  Unforeseeable events for which REETEC is not answerable (e.g. lack of energy, delay in the delivery of essential components and other materials, importation difficulties, interruption of operations and traffic disruptions, strikes, lockouts, force majeure) extend the delivery time/ processing time accordingly. If the unforeseeable event lasts longer than three months, both customer and REETEC shall be entitled to withdraw from the contract. Customer damage claims shall be excluded. If REETEC withdraws, REETEC shall reimburse all payments already made to the customer without delay.

Breach of duty due to defects

The customer shall examine the goods immediately after receipt. Apparent defects shall immediately be notified in writing by the customer to REETEC, at the latest within 1 week of arrival of the goods.

d)   REETEC’s liability shall extend to freedom from defects of the goods / performance of work according to the general rules of technology at the time of the conclusion of the contract.

e)  Provided that REETEC has claims against its suppliers, its liability shall be at first fulfilled by assignment of claims to the customer who accepts said assignment for this case.

f)   If a claim against the supplier does not come into consideration or if the supplier rejects liability, at REETEC’s choice, the liability shall at first be limited to supplementary performance, i.e. replacement delivery or rectification.

If supplementary performance fails or REETEC is not in a position to do so, the customer shall be entitled to withdraw from the contract or to reduce the purchase price.
