(2025-ESO-1347) 110/10/10 kV 40 MVA power transformers with tap changer

This tender, identified by reference (2025-ESO-1347), concerns the procurement of 110/10/10 kV 40 MVA power transformers equipped with tap changers. The procurement is being managed by ESO (Energijos skirstymo operatorius), the Lithuanian electricity distribution operator. The primary objective is to acquire high-quality power transformers essential for the reliable operation and expansion of the electricity distribution network. These transformers will play a crucial role in voltage regulation and power distribution across various substations within the ESO network. Key technical specifications will include the voltage levels (110 kV primary, with two 10 kV secondary windings) and a substantial power rating of 40 MVA. The inclusion of a tap changer is a critical requirement, enabling on-load adjustment of the transformer's voltage ratio to maintain stable voltage levels under varying load conditions. The evaluation criterion for submitted proposals is explicitly stated as the "Price/Cost and Quality Ratio," indicating that while cost-effectiveness is important, the technical quality, reliability, and performance of the transformers will be equally, if not more, significant in the selection process. Bidders are expected to demonstrate a strong understanding of the technical requirements and provide solutions that offer the best balance between initial investment and long-term operational value. This tender is vital for ensuring the continued modernization and efficiency of Lithuania's electricity infrastructure.

This is a supplies contract in the energy and power sector, with a focus on Transmission Distribution. Located in Lithuania, Europe, this opportunity is open to firms and consortiums.
