Subsequently, upon receipt of the mutually signed agreement, the supplier may begin to deliver invoices to the e-mail address specified in the agreement.

Slovenské elektrárne, a.s. will be ready to implement the new electronic invoicing requirements in accordance with the amendment to Act No. 222/2004 Coll. on Value Added Tax, effective since January 1, 2027.

Electronic invoices shall comply with the structured XML format requirements and will be delivered exclusively through certified delivery service providers. Unstructured documents, such as PDF invoices sent by email, will no longer be sufficient to meet the legislative requirements for electronic invoicing.

At the same time, we would like to inform you that the new electronic invoicing process, effective from 1 January 2027, will replace the electronic delivery of invoices under the Agreement on electronic delivery of invoices (the “Agreement”). The Agreement may continue to be used for the delivery of unstructured documents, such as advance payment invoices.

At the same time, Slovenské elektrárne, a.s. are preparing to expand its electronic communication options to include the receipt of structured documents voluntarily submitted through certified delivery service providers.
