General Terms and Conditions (GTC)
Version: 14 August 2026
This is a translation of the German original. In case of discrepancies, the German version shall prevail.
Scope of Application and Incorporation
These General Terms and Conditions (GTC) apply to all deliveries and services of NRG Solutions AG (NRG Solutions) in connection with battery storage systems, energy management systems and the associated engineering, planning, integration, delivery, installation, commissioning, operation, maintenance, support, consulting and management services.
These GTC are incorporated upon the signing of the offer by the customer, upon the order confirmation by NRG Solutions or upon the signing of a contract. The customer's own terms and conditions apply only if NRG Solutions has agreed to them in writing.
Contract Documents and Order of Precedence
The parties agree the services, the remuneration and the project-specific requirements in the individual agreement, in the signed offer, in the order confirmation or in the annexes expressly incorporated.
In the event of contradictions, the individual agreement and those of its annexes expressly designated as taking precedence shall prevail over these GTC. Operation and maintenance contracts, service level agreements, management contracts, technical specifications, data protection and remote access annexes as well as financing agreements shall prevail over these GTC for their respective subject matter.
These GTC supplement the contract documents exclusively in respect of points not regulated therein.
Offer and Conclusion of Contract
Offers from NRG Solutions are non-binding unless they are expressly designated as binding. An offer is valid only during the period of validity stated therein.
A contract is concluded by the written acceptance of an offer by the customer, by the written order confirmation by NRG Solutions, by an agreement signed by both parties or in another clearly documented manner.
NRG Solutions is entitled to make technical, design-related or production-related changes, provided that these are reasonable for the customer, do not impair the agreed purpose and do not violate specifications expressly agreed as binding.
Information in brochures, presentations, calculations, drawings, illustrations, data sheets and other documents is non-binding unless it is expressly designated as binding in the individual agreement or in a technical annex.
Scope of Services and Cooperation of the Customer
The nature and scope of the deliveries and services owed are determined exclusively by the contract documents. NRG Solutions does not owe any services that are not expressly contained therein or recognisable therein in good faith.
The customer shall provide NRG Solutions in good time with all information, documents, access, approvals and acts of cooperation required for the agreed services. This applies in particular to accurate site, grid, metering, load profile, communication and project data as well as, where agreed, access to installations, premises, IT and OT systems.
Unless otherwise regulated in the contract documents, the customer shall ensure at its own expense the timely performance of its on-site works, the necessary permits, safe access to the site as well as the availability of the necessary energy, grid and communication infrastructure.
Delays, additional expenditure or impediments to performance attributable to incomplete, late or incorrect cooperation of the customer or of third parties engaged by the customer shall not be borne by NRG Solutions. NRG Solutions shall inform the customer of the recognisable consequences and is entitled to adjust deadlines appropriately as well as, after prior notice, to invoice the documented additional expenditure caused thereby.
Prices, Taxes and Payment Terms
Unless expressly agreed otherwise, prices are understood to be in Swiss francs and exclusive of statutory value added tax as well as any expressly agreed disbursements and charges.
Invoices are payable within the payment period stated on the invoice or in the individual agreement. In the absence of a payment period, invoices are due within 30 days of the invoice date.
Upon expiry of the payment period, the customer is in default without further reminder. From the onset of default, NRG Solutions may claim default interest of five per cent per annum as well as the documented reasonable costs of enforcing the claim.
In the event of default in payment or of justified doubts as to the customer's solvency, NRG Solutions may, after appropriate prior notice, suspend services not yet rendered or make their further performance conditional upon an appropriate advance payment or security. Mandatory statutory rights of the customer remain reserved.
The customer may set off claims of NRG Solutions only against undisputed counterclaims or counterclaims established by a final and binding decision, unless mandatory law provides otherwise.
Deadlines, Delays and Force Majeure
Dates and deadlines are non-binding target dates unless they are expressly designated as binding in the individual agreement.
If NRG Solutions is unable to meet a deadline due to a circumstance outside its reasonable control, the deadline shall be extended appropriately. Such circumstances include in particular missing or late cooperation of the customer, delays on the part of authorities or grid operators, delivery and transport impediments, disruptions to communication or energy infrastructure, failures of third-party services as well as events of force majeure.
Force majeure exists where an unforeseeable event outside the control of the affected party substantially impedes or prevents performance. This includes in particular natural events, fire, war, terrorism, civil unrest, epidemics or pandemics, official orders, extensive labour disputes and large-scale failures of critical infrastructure.
The affected party shall inform the other party without delay of the anticipated consequences. If an impediment to performance persists, the parties shall agree on how to proceed. Where further waiting is no longer reasonable for the customer, either party may terminate the directly affected part of the services not yet performed. Services already rendered and contractually owed costs incurred up to termination remain payable.
Title and Rights in Documents
Until payment in full, movable goods delivered on a purchase basis remain the property of NRG Solutions, provided that a retention of title can be legally validly established.
Where delivered components are joined to a property or an installation and thereby cease to be treated legally as movable goods, ownership, rights of use and any security interests are determined exclusively by the individual agreement or by a separate financing agreement. In every case, NRG Solutions receives a contractual right to enter the property and / or the installation in order to enforce a contractual claim for restitution.
NRG Solutions retains all rights in offers, concepts, plans, drawings, calculations, software configurations, documentation and other documents. The customer may use these documents only for the purpose provided for in the contract. Disclosure to third parties is permitted only where it is necessary for the performance of the contract or where NRG Solutions has given its prior written consent.
Third-party rights, in particular those of manufacturers and software providers, remain reserved. Rights of use in software and digital services are determined by the individual agreement and by the applicable licence terms.
Inspection, Notice of Defects and Subsequent Performance
The customer shall inspect deliveries and services within a reasonable period after handover, acceptance or performance, insofar as an inspection is possible and reasonable given the nature of the service. The customer shall notify NRG Solutions of recognisable defects in writing without culpable delay and shall describe them in such a way that NRG Solutions is able to carry out an examination.
The customer shall grant NRG Solutions the opportunity and the access required to examine a reported defect, insofar as this is reasonable. The customer shall take appropriate measures to avoid further damage.
In the case of a defect reported in good time and with justification, NRG Solutions is initially entitled, at its own discretion, to remedy the defect or to provide a replacement. The further rights of the customer are governed by the individual agreement and by mandatory law.
Acceptance procedures, guarantees, performance values, availability, degradation, maintenance obligations, response times, spare parts and specific legal consequences are regulated conclusively in the relevant individual agreement or its annexes. These GTC do not create any guarantee or warranty of quality going beyond the individual agreement.
Liability
NRG Solutions is liable for damage caused intentionally or through gross negligence as well as for culpably caused personal injury. Any further liability is excluded to the extent permitted by law.
In all other respects, NRG Solutions is liable only for direct damage caused by a culpable breach of a material contractual obligation. To the extent permitted by law, liability for indirect damage and consequential damage is excluded. This includes in particular loss of profit, unrealised savings, production downtime, lost market or marketing revenues, the costs of replacement procurement, reputational damage and loss of data.
NRG Solutions is not liable for damage based on circumstances outside its control. This includes in particular acts or omissions of the customer or of third parties engaged by the customer, incorrect or incomplete customer data, grid disruptions, official restrictions, unavailable third-party services unless NRG Solutions has expressly warranted them, failure to observe manufacturer specifications, unauthorised interventions, unsuitable operating conditions as well as force majeure.
Where a service depends on market prices, regulatory conditions, grid or system availability, services of third parties or other factors beyond the control of NRG Solutions, NRG Solutions does not warrant any particular economic outcome. In particular, forecasts, model calculations, expected savings or expected revenues do not constitute a guarantee unless this is expressly agreed in the individual agreement.
Deviating liability rules and legal consequences in the event of failure to achieve agreed service levels apply only where they are expressly regulated in the relevant individual agreement.
Engagement of Third Parties
NRG Solutions is entitled to engage group companies, manufacturers, suppliers, service partners, specialist planners, installers and other auxiliary persons for the performance of the contract.
NRG Solutions remains the contracting party and point of contact vis-à-vis the customer unless expressly agreed otherwise in the individual agreement.
The engagement of a third party does not create any direct contractual relationship between that third party and the customer unless a separate agreement is concluded.
Confidentiality and Data Protection
The parties shall treat non-public commercial, technical and operational information of the respective other party as confidential. They may use this information only for the performance of the contract and may make it accessible only to persons or third parties who need to know it for the performance of the contract and who are themselves appropriately bound to confidentiality.
The confidentiality obligation does not apply to information that was already lawfully known to the receiving party, that becomes publicly known without breach of this obligation, that is obtained from an authorised third party without an obligation of secrecy, or that must be disclosed on the basis of mandatory statutory provisions or an official order. Where legally permissible, the affected party shall inform the other party prior to such disclosure.
NRG Solutions processes personal data and technical operating data insofar as this is necessary for the initiation, conclusion and performance of the contract, for ensuring safe operation and for compliance with statutory obligations. Further provisions result from the applicable privacy policy, from a data protection and remote access annex or from a data processing agreement.
Applicable Law and Place of Jurisdiction
The contractual relationship is governed by Swiss law, excluding the United Nations Convention on Contracts for the International Sale of Goods of 11 April 1980.
The courts at the registered office of NRG Solutions have jurisdiction over disputes arising from or in connection with the contractual relationship, provided that a choice of forum agreement is legally permissible and that nothing else is regulated in the relevant individual agreement.
Final Provisions
Amendments and additions to the individual agreement require at least written form unless a stricter form is expressly agreed in the individual agreement. A qualified electronic signature is equivalent to written form.
Should a provision of these GTC be or become wholly or partly invalid or unenforceable, this shall not affect the validity of the remaining provisions, to the extent legally permissible.
The version of these GTC in force at the time the contract is concluded shall be authoritative. For contracts newly concluded from their entry into force, these GTC replace all earlier versions of the GTC of NRG Solutions.
In the case of translations of these GTC, the German version shall prevail unless mandatory law provides otherwise.
We develop, implement and operate modular large-scale battery storage systems (BESS) for stable and sustainable energy supply in Switzerland.
