General Terms and Conditions for the Sale of Electricity to Businesses

Effective as of 10 May 2026

These terms apply to the sales agreement between the Customer and Hehku Energia Oy (“Seller”), under which the Customer purchases, and the Seller sells, electricity.

1. Entry into force, term and termination of the Sales Agreement

1.1 A Sales Agreement between the Customer and the Seller is formed when the Customer has accepted the Seller’s offer in writing, including electronic acceptances such as email or electronic signature, or orally in a manner verified by the Seller. The signatory of the Sales Agreement confirms that, by virtue of their position, they are authorised to sign the Sales Agreement on behalf of the Customer. The Sales Agreement consists of the Customer’s contract-specific terms, these General Electricity Sales Terms for Companies, and the general electricity sales terms of the energy sector (SME 2024). In the event of any conflict between the different terms, the Customer’s contract-specific terms shall apply first, followed by these terms, and thereafter the general electricity sales terms of the energy sector in force from time to time.

1.2 For the supply of electricity, the Customer must have a separate electricity network agreement with the network operator. The Seller is not liable for any faults in the electricity network, interruptions in electricity transmission, or any omissions by the network operator.

1.3 Commencement of electricity supply to the consumption sites specified in the Sales Agreement on the agreed date requires that the Customer provides the Seller with the necessary information before the agreed supply start date. During the contract term, the Customer is obliged to notify the Seller without delay of any changes to company or consumption site information. Commencement of supply under the Sales Agreement also requires that, on the supply start date, there is no fixed-term agreement in force with another electricity seller for the consumption site covered by the Sales Agreement. The Customer is obliged to ensure that electricity supply to the consumption site specified in the Sales Agreement can begin on the start date agreed by the parties. If these or similar delays independent of the Seller occur, the Sales Agreement shall commence without undue delay, but no earlier than once the obstacle has been removed. If the commencement of electricity supply is delayed for reasons independent of the Seller, the Seller has the right to revise the pricing of the Sales Agreement and the grounds for determining such pricing to correspond to the changed procurement situation and the costs arising from it. The revised pricing shall enter into force when electricity supply begins. By signing the Sales Agreement, the Customer authorises the Seller to handle the practical arrangements related to changing the electricity seller without a separate power of attorney.

1.4 The Customer is responsible for ensuring that the metering of the consumption site and the transfer of consumption data meet the requirements of electricity market legislation. If the metering or data transfer does not function properly and the fault is not corrected within a reasonable time after notification by the Seller, the Seller has the right to suspend supply to the relevant consumption site or exclude the consumption site from the agreement.

1.5 The Sales Agreement shall remain in force, in accordance with the agreement, either until the end of the agreed fixed term or until further notice. Fixed-term agreements are binding for the entire contract term. If the Customer wishes to terminate a Sales Agreement valid until further notice or a fixed-term Sales Agreement prematurely, or neglects its payment obligations in such a manner that the Sales Agreement must be terminated with immediate effect, the Seller has the right to receive compensation from the Customer in accordance with section 5.2.

1.6 If the Customer has not notified the Seller in writing of termination no later than 30 days before the expiry date of the fixed-term Sales Agreement, changed electricity seller, or concluded a new Sales Agreement with the Seller after the end of the fixed-term contract period, the contractual relationship between the parties shall automatically continue without separate notice as an electricity spot price agreement valid until further notice, at the billing prices set out in the Seller’s public service price list.

The separate public service price list applicable to the agreements, as in force from time to time, is valid until further notice, and the Seller has the right to amend it without separate notice. Changes to the service price list are not considered amendments to the terms of the Sales Agreement, and they do not give rise to a right to terminate a fixed-term Sales Agreement.[MH1.1]

1.7 A Sales Agreement valid until further notice shall remain in force until further notice, and the notice period for both parties is 90 days, unless otherwise agreed in the Sales Agreement. The notice period begins when the notice of termination has been delivered to the other party.

The Sales Agreement may be terminated without specific grounds. Termination must be made in writing so that the sender and timing of the notice can be verified, or in another manner approved by the Seller. Electricity supply shall continue normally until the end of the notice period and shall end when the notice period expires.

2. Price, invoicing and payment terms

2.1 The price shall be as agreed in the Sales Agreement between the parties. The price does not include transmission or network charges invoiced by the local electricity distribution company, or electricity tax, value added tax or other taxes. Unless otherwise agreed, the price includes Fingrid’s production and consumption volume fee in force at the time the Sales Agreement is concluded.

The Sales Agreement and its pricing are based on the electricity consumption volumes reported by the Customer when the Sales Agreement is concluded, or on electricity consumption volumes and consumption profile data received from the network company or the previous electricity seller. If the electricity consumption volumes or electricity consumption profile reported or estimated when the Sales Agreement is concluded differ from the actual electricity consumption or electricity consumption profile, the Seller has the right to revise the pricing in accordance with section 4.5. The value added tax rate in force from time to time shall be applied in the invoicing of the Sales Agreement.

2.2 Invoicing is primarily based on the electricity consumption data reported and maintained by the network operator. If actual metering data is not available, invoicing may be based on estimated consumption.

In estimated invoicing, invoicing is based on estimated electricity consumption, for example when actual metering data is not available or when invoicing is based on estimated consumption in accordance with the invoicing procedure applied by the Seller. The difference between estimated and actual consumption shall be balanced in later invoicing on the basis of the actual electricity consumption reported by the network operator.

In advance invoicing, an invoice may be charged before the electricity is used. The difference between the advance payment made and actual consumption shall be balanced in later invoicing on the basis of actual electricity consumption.

As a rule, invoicing takes place monthly based on consumption. However, the Seller has the right to deviate from the invoicing rhythm and invoicing period, for example in situations where the amount to be invoiced is minor or where a credit is generated for the Customer. The Seller also has the right to combine charges for several invoicing periods into the same invoice. Invoicing shall, however, be carried out at least in the manner required by the legislation applicable from time to time.

The Seller has the right to charge the Customer a fee for delivering a paper invoice in accordance with the price list in force.

2.3 The Customer shall pay the Seller the electricity charges under the Sales Agreement no later than 14 days from the invoice date, unless otherwise agreed in the Sales Agreement. Any remarks concerning the invoice must be made within a reasonable time, but no later than before the due date of the invoice. In respect of delayed payments, in addition to the unpaid amounts, the Seller has the right to charge default interest in accordance with the Interest Act in force from time to time, calculated from the due date, as well as compensation for costs arising from the delay, including reminder fees, standard compensation and enforcement costs of collection in accordance with the Seller’s service price list.

2.4 If the Customer neglects to pay overdue charges, securities or advance payments, the Seller has the right to suspend electricity supply to the Customer. The Seller also has the right to suspend electricity supply if the Customer otherwise materially or repeatedly fails to comply with the contractual terms. Before electricity supply is suspended, the Customer shall be given a disconnection warning, after which the Customer has the opportunity to make the payment, provide the security or remedy the breach of contract before the electricity supply is suspended. If the Seller has the right to suspend electricity supply on the above grounds, the Seller also has the right to terminate the Sales Agreement with immediate effect. The Customer is responsible for the costs arising from the suspension and reconnection of electricity supply. The costs are determined on the basis of the charges of the local network operator and any fees payable under the Seller’s service price list[MH2.1].

2.5 The Customer confirms that, at the time the Sales Agreement is concluded, interruption of electricity sales to any of the Customer’s consumption sites does not create an accident risk as referred to in section 103 of the Electricity Market Act. If any changes occur in this respect, the Customer must notify the Seller thereof in writing without delay.

3. Credit information, advance payments and securities

3.1 The Seller has the right, before concluding the Sales Agreement and during its validity, to check the Customer’s credit information and obtain the Customer’s confirmed financial statements for the most recently ended financial year. This may lead to the Seller refusing to enter into the agreement or to the agreement being rejected. If the review reveals deficiencies in the Customer’s financial capacity and the Seller considers it necessary, the Seller has the right, during the validity of the agreement, to require the provision of sufficient security or an advance payment, or supplementation of an existing security or advance payment, to the Seller. The Seller also has the right to refuse a contractual relationship if it has a justified reason to suspect, including but not limited to matters relating to the Customer’s sanctions status, payment behaviour, risk classification or credit information, that the Customer will not fulfil its obligations under the Sales Agreement. The Customer is obliged to notify the Seller without delay of any material changes in its financial position that may affect the fulfilment of contractual obligations.

3.2 The security or advance payment must be sufficient to cover the financial risks related to the agreement as estimated by the Seller, including estimated electricity consumption and price risks related to electricity procurement. If the Customer has several agreements with the Seller, all agreements shall be considered as a single whole in the assessment of security or advance payment, and the security or advance payment may be used to fulfil obligations under any agreement. The Seller shall determine the amount of the security or advance payment.

3.3 If the Customer does not provide security at the Seller’s request or pay the advance payment by the due date set by the Seller, the Seller has the right to terminate the Sales Agreement with immediate effect without a separate notice period. The Customer is obliged to pay for the electricity used up to the time of termination in accordance with the contract prices, as well as any costs arising as a result of the termination procedure, including, among other things, electricity procurement costs incurred by the Seller and other costs arising from termination of the agreement, as well as compensation calculated in accordance with section 5.2 for the remaining fixed-term period of the Sales Agreement.

4. Amendments to terms and prices

4.1 The Seller is entitled to amend the pricing of the Sales Agreement due to changes in legislation, decisions and orders of authorities, taxes, tax-like charges, and changes to Fingrid Oyj’s balance service fees and other fees, as from the entry into force of such changes, without separate notice. The aforementioned changes also apply to fixed-term Sales Agreements. For the sake of clarity, it is stated that changes under this section do not entitle the Customer to terminate or cancel a fixed-term Sales Agreement.

4.2 The Seller is entitled to amend the prices or other contractual terms of the Sales Agreement due to changes in electricity price areas, the applicable imbalance settlement period, or other corresponding changes in the structure of the electricity market. The aforementioned changes also apply to fixed-term Sales Agreements.

4.3 In other respects, the Seller has the right to amend the pricing and the related terms by notifying the Customer of the amendments at least 14 days in advance in accordance with section 7.1. The amendments shall enter into force on the date stated in the notice and may be taken into account in future invoices.

4.4 The Seller also has the right to amend prices in the situations referred to in section 8.5 of the SME 2024 terms.

4.5 In addition to the general terms and conditions of the energy sector, the Seller has the right to amend the pricing also in fixed-term Sales Agreements if the electricity consumption reported by the Customer, including the electricity consumption profile, meaning the temporal distribution of electricity use, materially differs from the actual electricity consumption and this causes additional costs to the Seller. If the Customer has not reported electricity consumption when concluding the Sales Agreement, the consumption estimate of the distribution network operator shall apply. The deviation is considered material when actual electricity consumption or the electricity consumption profile differs by more than 10 per cent from the reported or estimated electricity consumption.

In such case, the Seller has the right to invoice the Customer for the cost impact caused by the deviation as a separate charge. The charge may be made in one or more instalments, and it may be allocated to one or more review periods and taken into account in invoices relating to the relevant period or in later invoices. The Seller has the right, but not the obligation, to take into account the actual electricity consumption of later periods and to make a balancing adjustment if necessary.

4.6 The Seller has the right to amend these terms by notifying the Customer at least 14 days before the entry into force date of the new terms. The notice shall be delivered to the Customer in accordance with section 7.1.

5. Expiry, termination with immediate effect and compensation

5.1 The Seller has the right to terminate the Sales Agreement with immediate effect if the Customer materially breaches its obligations under the Sales Agreement and does not remedy the breach within the reasonable period notified by the Seller.

A material breach of contract includes, among other things, failure to pay overdue charges, securities or advance payments, as well as a situation where electricity supply ends before the end of the contract term as a result of the Customer’s actions or its commencement is prevented for a reason independent of the Seller.

5.2 If the Sales Agreement is terminated with immediate effect in accordance with section 5.1, or if a fixed-term Sales Agreement ends prematurely for a reason attributable to the Customer, the Customer is obliged to pay for the electricity used up to termination in accordance with the Sales Agreement and to compensate the Seller for the costs arising from the termination. In addition, the Seller has the right to charge the Customer compensation for premature termination corresponding to the costs and other damage incurred by the Seller due to the premature termination of the Sales Agreement. The costs and damage arising from premature termination shall always amount to at least twenty per cent (20%) of the estimated total invoicing for the remaining contract term, but in any case at least EUR 800. The electricity consumption estimate is based on the network operator’s annual consumption estimate or on the actual electricity consumption of the previous year for the relevant period, whichever is higher.

Termination of the Sales Agreement due to the Customer giving up the consumption site, discontinuing operations, a change in ownership or right of possession, or another similar reason does not release the Customer from the obligations under this section, unless the Seller has approved the termination or transfer of the agreement. At the Seller’s request, the Customer must present reliable evidence of such changes.

6. Force majeure and liabilities

6.1 The Seller is not liable for the performance of the Sales Agreement and is not liable to compensate for any damage caused by force majeure. Force majeure means an unforeseeable event independent of a contracting party, with exceptional effects, which could not reasonably have been avoided or overcome, and which prevents or makes it unreasonably difficult to fulfil contractual obligations, such as war, an order by an authority, disruption in the electricity market, a natural phenomenon or another corresponding circumstance.

6.2 Both parties have the right to compensation for direct damage caused by the other party’s negligent or intentional breach of contract. The parties are not liable to each other for indirect or consequential damage, such as interruption of production, loss of profit or other similar damage, unless the damage has been caused intentionally or through gross negligence.

The Seller’s liability for damages is limited to an amount corresponding to a maximum of 10 per cent of the VAT-exclusive amount invoiced by the Seller from the Customer during the preceding 12 months, but in any case to a maximum of EUR 3,000 per damage event.

If electricity supply is interrupted or ends due to legislation, an order by an authority or another mandatory reason, the parties’ obligations shall end to the extent that they cannot be fulfilled.

The above limitation of liability does not limit the Seller’s right to receive compensation for the Customer’s breach of contract in accordance with section 5.

7. Notices and other terms

7.1 The Seller shall deliver notices concerning the Sales Agreement electronically to the contact details provided by the Customer or through an electronic service used by the Seller, such as by email, through an electronic customer service portal, or in connection with an electronically delivered invoice.

A notice is deemed to have come to the Customer’s attention at the time it is sent, unless otherwise proven. The Customer is responsible for keeping its contact details up to date.

If these terms require notice to be given within a certain time before the entry into force of a change, the notice shall state the effective date of the change, and the changes shall enter into force on that date.

7.2 The Customer is obliged to notify the Seller without delay of material changes in ownership or legal status, such as changes in company form, merger or demerger. The Customer must notify the Seller without delay if the Customer is placed into liquidation or if an application concerning corporate restructuring is filed.

7.3 The Seller has the right to transfer the Sales Agreement and the rights and obligations based on it to a third party. The Customer may not transfer the Sales Agreement or its rights or obligations based on it to a third party without the Seller’s prior consent.

7.4 The Seller has the right to record calls related to the implementation of the Sales Agreement in accordance with applicable legislation.

7.5 The Seller has the right to use the Customer’s name as a reference in its ordinary marketing, unless the Customer has separately prohibited this.

8. Applicable law and dispute resolution

The Sales Agreement is governed by the laws of Finland. Any disputes arising from the Sales Agreement shall primarily be resolved through negotiations between the parties. If no resolution is reached through negotiations, the disputes shall be finally resolved by the Helsinki District Court.

However, the Seller has the right to bring claims concerning overdue receivables before a competent court.
