4. The Turkish Electricity Transmission Corporation now invites eligible consulting firms (“Consultants”) to indicate their interest in providing the Services. Interested Consultants should provide information demonstrating that they have the required qualifications and relevant experience to perform the Services.

5. A consulting firm is allowed to submit the expression of interest alone if it considers itself to be fully qualified on its own for the assignment, as it is not mandatory for consultants to associate with any other firm(s), whether foreign or local. Alternatively, if consultants themselves choose to associate to enhance their qualifications and capability for the assignment, then such associations may either be as a Joint Venture (i.e. all members of the joint venture shall be jointly and severally responsible) and/or Sub-consultants (i.e. the Consultant will be responsible, including for the services of the sub-consultant). In case of an association, the Consultants must explain in the EOI submission (a) the rationale for forming the association and (b) the anticipated role and relevant qualifications of each member of the Joint Venture and/or of each sub-consultant for carrying out the assignment, to justify the proposed inclusion of the JV members and/or sub-consultants in the association. Failure to provide the above explanation in the Expression of Interest may risk the association not being shortlisted for the assignment. Please note that in the evaluation of EOIs of associations for shortlisting purposes, only the qualifications of the JV members will be taken into account whereas the qualifications of proposed sub-consultants will not be considered.

i. General Experience of the Consultant (as a firm) in providing consultant services:

• Experience delivering consultancy services under public sector utility frameworks, preferably involving TSOs or ministries.

iii. Preferred Experience –In addition to the general and specific experience required above, the following qualifications and references will be considered highly advantageous during shortlisting process:

• Familiarity with international standards (e.g., IEC, IEEE, CIGRÉ) and experience in multi-disciplinary engineering consultancy projects involving grid integration studies, control and protection systems, and simulation models will be evaluated favorably.
• Familiarity with the Turkish Transmission Network operational practices, protection schemes, interconnection policies, and regional grid stability challenges is considered a strong advantage.

• Familiarity with the Turkish regulatory and operational environment is also an advantage.
• Participation in the design, validation, or testing of HVDC converter control systems, including model validation, parameter tuning, and laboratory-based real-time simulations, is considered an asset.

These qualifications are not mandatory but will contribute significantly to the scoring during shortlisting.

7. To demonstrate their qualifications and experience in meeting the above shortlisting/selection criteria, Consultants are requested to submit, at a minimum, the supporting documentation listed below. A consultant firm can only use its own qualifications and experience and not of its parent, sister or subsidiary companies or its employees.
