ESIDIS 2026: What Changes in Preliminary Market Consultations and Electronic Communication
A new regulatory framework, upgraded digital procedures, and increased requirements for public procurement management. What Contracting Authorities and Economic Operators need to know.
The National Electronic Public Procurement System (ESIDIS) is entering a new phase of modernization. Significant changes affect preliminary market consultations, electronic communication, and document management throughout tender procedures.
Joint Ministerial Decision 61267/17.07.2026 (Government Gazette B’ 4578/24.07.2026) amends Joint Ministerial Decision 64233/2021. It further specifies the operational framework of the ESIDIS Integrated Information System for public supply and service contracts.
The new provisions focus on two main areas: user management within the preliminary consultation subsystem and electronic communication, notifications, and document exchange.
The changes apply to public procurement procedures for supplies and services initiated after the decision’s publication, namely after July 24, 2026.
For public organizations, municipalities, regional authorities, hospitals, and public or private legal entities subject to the relevant framework, these developments highlight the need for better procurement organization and more comprehensive documentation of electronic activities.
What Changes in ESIDIS in 2026?
Joint Ministerial Decision 61267/2026 introduces specific amendments to the system’s regulatory framework. The most significant changes concern the addition of Article 6a, which regulates user management within the preliminary consultation subsystem, and amendments to Article 9 concerning electronic communication and document exchange.
In addition, the previous provisions of Articles 22 and 23 of the amended decision are repealed. These articles concerned transitional arrangements and entry into force. The amendments aim to establish clearer electronic procedures, strengthen legal certainty, and improve the documentation of activities carried out through the platform.
The key point is that electronic public procurement management extends beyond submitting bids. It also includes communication, notifications, document retention, and monitoring critical deadlines.
ESIDIS Preliminary Market Consultations: New User Management Rules
Preliminary market consultations are an important tool for preparing public procurement procedures. Under Articles 46 and 47 of Law 4412/2016, Contracting Authorities may seek or receive opinions, advice, and technical observations before launching a tender procedure. These contributions may come from economic operators, independent experts, and other interested parties.
This process supports more effective technical specification planning and a better understanding of available market solutions. However, authorities must use the feedback without restricting competition or violating the principles of equal treatment, non-discrimination, and transparency.
What Does the New Article 6a Provide?
Joint Ministerial Decision 61267/2026 introduces a specific provision governing users of the “Preliminary Consultations” subsystem. Management users include officials from Contracting Authorities, Contracting Entities, and Central Purchasing Bodies responsible for creating and managing the relevant procedures.
User registration and access rights management follow the rules applicable to users of the Central Electronic Registry of Public Contracts (KIMDIS), in accordance with Joint Ministerial Decision 4968/2026.
This establishes a clear framework for identifying and managing the officials responsible for consultations. Consequently, procurement departments must pay particular attention to assigning responsibilities correctly and maintaining up-to-date access rights.
How Is a Preliminary Market Consultation Conducted?
The procedure begins with a specific invitation identifying the Contracting Authority, the subject of the planned contract, the technical requirements, and the method for submitting comments.
As a general rule, the invitation is published through the ESIDIS Integrated Information System and on the Contracting Authority’s website, subject to exceptions provided by law.
A preliminary consultation conducted through ESIDIS lasts at least 15 days, in accordance with Article 47 of Law 4412/2016.
Following completion, the Contracting Authority collects, records, and evaluates the comments in accordance with legal requirements. The electronic procedure facilitates documentation and can help develop functional, technology-neutral, and more competitive specifications.
Important clarification: The relevant public service allows interested parties to search for consultations and submit comments without login credentials. This differs from the access rights granted to authorized officials who create and manage consultations.
Electronic Communication in ESIDIS: What Does the Amended Article 9 Provide?
The amendment to Article 9 of Joint Ministerial Decision 64233/2021 is particularly important. It specifies the procedures for communication, notifications, and document exchange through the ESIDIS Supplies and Services subsystem.
Communication within an electronic procurement procedure takes place exclusively through the subsystem, using its designated electronic areas.
The “Communication” feature serves as the main tool for exchanging messages and notifications between Contracting Authorities and Economic Operators. Furthermore, the system provides separate electronic areas for uploading documents, submitting bids, and collecting information for the Public Contract File.
Electronic Transmission Has Evidentiary Significance
A critical aspect of the amended Article 9 concerns documenting the sending and receipt of electronic messages. Specifically, the platform records information that serves as evidence of electronic communication. This includes timestamps for sending, notification, submission, and uploading.
Furthermore, the system treats the successful sending of a message through the “Communication” feature as successful receipt by the recipient. Therefore, authorized users must systematically monitor electronic communications relating to the tender procedures in which they participate. Consequently, failure to read a message does not automatically postpone the time of notification.
How Are Deadlines Calculated?
Article 9 also specifies how the relevant deadlines are calculated. Under the provision’s general rule, deadlines begin on the day following the corresponding transmission, notification, or submission. Unless the contract documents specify a different time, the deadline expires at 23:59:59 on the final day.
If the final day falls on a non-working holiday or a Saturday, the deadline is extended to the next working day, in accordance with the specific provision. Applying these rules requires particular attention, especially when special deadlines or different provisions govern specific procedural actions. For procurement departments, monitoring electronic notifications and deadlines is no longer merely an organizational requirement. It is an essential element of proper tender management.
Electronic Public Contract File: Centralized Monitoring and Documentation
The new framework identifies the electronic areas of ESIDIS that constitute the location where the Public Contract File is maintained. The electronic file links tender procedure information with the corresponding submissions, notifications, and other documents. Proper file management is particularly important for administrative and legal reviews, information retrieval, and documenting the Contracting Authority’s decisions. A complete and well-organized electronic file improves traceability and facilitates monitoring throughout the procedure, from preparation to contract award and subsequent stages.
New ESIDIS Features Available from September 7, 2026
Beyond regulatory changes, ESIDIS is also evolving technologically. According to the September 11, 2026 announcement by the General Secretariat for Information Systems and Digital Governance, new features became operational on September 7, 2026. A key improvement is the ability to download multiple attachments from electronic tender procedures in bulk. This feature covers published attachments available through tender searches, files uploaded to the “Notes and Attachments” area, and bid documents accessible to the corresponding authorized users. This represents a significant functional upgrade, as bulk document downloads can reduce processing time and simplify file organization.
The New ESIDIS Integrated Information System: Digital Transformation Across the Public Procurement Lifecycle
The new ESIDIS Integrated Information System is part of Greece’s National Recovery and Resilience Plan, “Greece 2.0”. Upgrade aims to improve management across the entire public procurement lifecycle, from needs planning and tender procedures to contract execution and completion. Planned developments include new forms of electronic purchasing, such as eCatalogues, eShops, and eMarketplaces. They also include expanded interoperability capabilities with public-sector information systems.
These capabilities form part of the broader transformation and should not be confused with the specific features already operational in September 2026. Nevertheless, the direction is clear: public procurement is gradually moving toward a more integrated, digital, and interoperable environment.
What Should Contracting Authorities and Procurement Departments Pay Attention To?
Proper implementation of the new framework requires organizations to adapt their internal procedures.
The main priorities for Contracting Authorities include:
- Updating user access rights: Reviewing authorized officials and the procedures for registration and access.
- Conducting preliminary consultations correctly: Ensuring appropriate publication, compliance with statutory deadlines, and evaluation of market feedback.
- Systematically monitoring electronic communication: Reviewing messages, notifications, clarification requests, and critical procedural actions.
- Documenting the electronic contract file: Organizing documents and records that support procedural compliance.
- Training and supporting personnel: Informing users about regulatory changes and the platform’s new features.
Adequate preparation can help reduce omissions, delays, and procedural errors.
