This clarification will ensure objective competition without compromising the technical requirements for the equipment.Dear Bidder,Thank you for your request.The power ranges of the generators for each of the lots was established based on the needs and technical requirements of the end users of the equipment. The maximum possible allowable tolerance was provided in the technical requirements after careful technical assessment. Deviations that exceed the tolerance provided in the technical requirements for each lot is therefore not acceptable.Thank you.

New clarification added: Dear UNOPS, In Section II you write: Bidders shall deliver and unload the goods as soon as possible but not later than within 150 days after contract issuance. Bidders must provide realistic delivery time for the proposed goods. Does it mean bidders offering longer period of delivery (over 150 days) will be rejected?Dear Bidder,Thank you for your request.Please note that the delivery requirements are the mandatory requirements for the RFQ. Bidders offering longer delivery periods than required could not be considered substantially compliant with the requirements however the RFQ methodology allows to award the contract to the lowest priced most technically acceptable offer if there are no substantially compliant offers.Thank you.

New clarification added: File: RFQ_Section_II_Schedule of requirements_Gas cogeneration units_RFQ_2025_59888_Lot 1RFQ_Section_II_Schedule of requirements_Gas cogeneration units_RFQ_2025_59888_Lot 2RFQ_Section_II_Schedule of requirements_Gas cogeneration units_RFQ_2025_59888_Lot 3Information from tender documentation: 22.18 System requirements for air start - a filter element must be provided in the combustion air supply.Question:EN: Please note that the requirement of clause 2.18 for air start applies exclusively to installations with significantly higher installed capacity and a different design class than those specified in lots 1–3. In cogeneration plants covered by these lots, electric starter launch is standard and technologically justified, while air launch systems are not structurally provided for and are not used. In this regard, we request that the requirement in clause 2.18 be deleted, as it is not relevant to lots 1–3 and does not correspond to the design and operational characteristics of equipment of the corresponding power class.Dear Bidder,Thank you for your request.Clause 2.18 reflects the operational needs defined by the end user.The clause requires that, if or where an air-start system is used by the offered CHP design, a filter element must be provided in the combustion air supply.This requirement does not mandate the use of an air-start system for all units. CHP units that use an electric starter, which is common for smaller capacities, remain fully acceptable as long as they comply with all other requirements of the tender.The specification therefore remains unchanged.Thank you.

For equipment of this class, the standard and technically acceptable operating gas pressure range is 20–50 mbar, while 2.0 atm is excessively high and structurally incompatible with typical CHP burner and gas control systems.In addition, the establishment of such a requirement necessitates the placement of a gas control point (GCP) directly next to the equipment, which creates additional risks for the recipient, both technical and operational. According to Ukrainian fire safety regulations, metal containers are classified as fire resistance class III-a, and placing a gas pressure regulating station with an inlet gas pressure of 2 bar directly on them is strictly prohibited.In this regard, we request that requirement 2.4.13 be clarified and adapted to the actual operating parameters by setting the inlet gas pressure within the limits acceptable for the equipment of lots 1–3, i.e., 20–50 mbar.Dear BidderThank you for your request.Clause 2.4.13 requires “gas inlet pressure - no more than 2.0 atm” which means that the lower inlet pressure is acceptable.Thank you.

Clause 2.12.1 provides for the use of a catalyst to reduce harmful emissions, but at the same time allows NOx levels of up to 500 mg/Nm³ at O₂=5%, which is incompatible with the use of a catalyst and contradicts the practice of its application.In addition, the limit of 500 mg/Nm³ creates unequal conditions for participants. According to current European environmental standards, manufacturers of cogeneration equipment must comply with much stricter standards — no higher than 250 mg/Nm³ at O₂=5%. This level is typical for equipment that meets EU requirements, which are currently being implemented in Ukrainian legislation.We propose to bring the requirement into line with European environmental standards and the actual capabilities of catalytic systems by setting a clear and unambiguous limit:NOx < 250 mg/Nm³ at O₂=5% This approach will ensure a level playing field for participants, compliance with international standards, and real environmental control of emissions.Dear Bidder,Thank you for your request.There is no inconsistency in the mentioned clauses of the Schedule of Requirements. In clause 2.12.1 “Emission control systems such as catalytic converters to reduce harmful emissions in compliance with environmental regulations” the “catalytic converters” provided for the reference purpose as a sample of potential emission control systems (“such as…”). The allowable emissions levels provided in clause 2.12.2 are compliant with the legislation and requirements of the end user of the equipment. The requirements can not be changed.The emission limits provided in the RFQ:- Are intentional and designed to maintain open competition.- Are technically acceptable for the power classes included in the RFQ.The current NOx limits in the RFQ:- Do not contradict Ukrainian environmental regulations.- Do not exclude equipment that meets stricter EU-based standards.Thank you.

Within the warranty period, the Supplier or its authorized service centre shall provide maintenance and/or repair services and/or replacement of the equipment not later than 30 (thirty) calendar days from the date of receipt of written or E-mail notification from an authorized party. The name of the company, address, telephone- and fax numbers, e-mail address must be mentioned in the bid. All costs connected with warranty maintenance are covered by the Supplier.1.7 The warranty for the equipment must be min. 1 year. Warranty must include manufacturing defects and labor, parts, and transportation charges.Question:EN: Please clarify the content of requirements 1.6 and 1.7 regarding warranty obligations. Do we understand correctly that this refers to covering the costs of warranty repairs (elimination of manufacturing defects, including labor, spare parts, and transportation costs), and not to full equipment maintenance during the warranty period?Please confirm that regular maintenance (consumables, fluids for filling systems) within the scheduled service intervals is not included in the tender price.Dear Bidder,Thank you for your request.The warranty requirements are clearly reflected in the Section II Schedule of Requirements. Under clause 1.7 of the Schedule of Requirements “Warranty must include manufacturing defects and labor, parts, and transportation charges” which refers to covering the costs of warranty repairs (elimination of manufacturing defects, including labor, spare parts, and transportation costs). Regular maintenance is not included in the warranty requirements.Thank you.

This tender also includes small and medium-sized CHP units (up to ~530 kW), for which such architecture is not usually used: engine and generator parameters are displayed through a single integrated control system, without separate physical instrument panels.To avoid technical limitations and ensure a level playing field for all participants, we request that this requirement be removed, noting that other approaches to parameter indication are permitted, provided that all necessary monitoring functions are implemented.Dear Bidder,Thank you for your request.Clause 2.17.7 reflects the functional monitoring requirements defined by the end user. The clause does not prescribe a specific hardware architecture (separate physical panels or integrated displays). What is required is that all monitored engine and generator parameters be clearly visible and accessible to the operator in accordance with the user’s operational needs.The requirement remains unchanged.Thank you.

Please confirm that within the scope of this requirement, the use of different technical approaches to building an automation system is permitted, provided that: all functions specified in the tender specifications, as well as the full list of requirements for security, control, and monitoring, will be implemented in full, regardless of the specific architecture of the controllers. This clarification will ensure a level playing field for participants and avoid unjustified restrictions on solutions that are technically fully compliant with the functional requirements of the tender.Dear Bidder,Thank you for your request.Clause 2.17.2 requires that “The CHP controller should be able to manage the entire container and associated automation.”We confirm that the requirement does not prescribe a specific control-system architecture. Bidders may use centralized, distributed, or hybrid controller configurations meeting the full functional requirements, provided that: 1) All functions specified in the tender requirements, including all safety, control, protection, and monitoring requirements, are fully implemented; and 2) The proposed control system ensures full and coordinated management of the entire container and all associated automation.Thank you.

Quotations for the commissioning services must be provided as a separate document (template is included in the Documents section) and will not be evaluated. Bidders are required to provide quotations for the commissioning services for information purposes only.Question:EN: Please note that clause 3.7, which requires the cost of commissioning and start-up services to be submitted separately and not taken into account when evaluating bids, may create certain difficulties in the Ukrainian market. There is a significant shortage of qualified specialists who perform such work in Ukraine, and as a result, a large number of cogeneration units already installed at facilities remain out of service and, accordingly, are not operating. As a result, the equipment is idle and may lose its resource prematurely.In view of these circumstances, we ask you to consider the possibility of including commissioning services in the tender proposal and taking them into account during the evaluation. This approach will contribute to the guaranteed commissioning of the equipment and increase the likelihood of successful project implementation.Dear Bidder,Thank you for your request.Please note that the budget of the project (within which this RfQ is conducted) does not envisage the commissioning services for the equipment. As specified in clause 3.7 of the Section II Schedule of Requirements “Quotations for the commissioning services must be provided as a separate document (template is included in the Documents section) and will not be evaluated. Bidders are required to provide quotations for the commissioning services for information purposes only.”.Thank you.
