Communique – invitation to public consultation on the Sustainability Report

The National Electricity Transmission Company "Transelectrica" SA invites the investing public and all interested parties to participate in a public consultation on the 2024 Sustainability Report.

Over the past few years, the Company has demonstrated its commitment to transparency and accountability by publishing sustainability reports in accordance with internationally recognized standards in force. Starting this year, the Company has taken an important step towards aligning with the new European requirements, publishing the Report in accordance with the ESRS (European Sustainability Reporting Standards). Thus, the 2024 Sustainability Report marked the implementation of a new regulatory framework that strengthened the requirements for sustainability reporting and alignment with European ESRS standards.

In order to continue to improve the reporting process and to reflect as accurately as possible the expectations of all stakeholders, we invite you to complete a short questionnaire (3–5 minutes). Responses are confidential and anonymous.

Those interested in participating are asked to send the completed form, by e-mail to irina.apostol@transelectrica.ro, by December 15, 2025.

Thank you in advance for your contribution and for your involvement in building sustainable, relevant reporting aligned with European standards!
