Description

This tender relates to the construction of a medium voltage (MV) power system for a customer in Hamburg-Harburg. The scope encompasses the installation of a single-feed MV switchgear, including one outgoing feeder to supply a 1600 kVA transformer. A crucial component is the inclusion of an Uninterruptible Power Supply (UPS) unit designed to provide an 8-hour bridging time during power outages. This indicates a requirement for a relatively resilient and reliable power supply, suggesting a potentially critical application for the customer.

The project's complexity lies in the integration of the MV switchgear, transformer, and UPS system. Contractors should assess their expertise in MV systems, transformer installations, and UPS integration, including sizing and commissioning. The single-feed and single-outgoing feeder configuration simplifies the switchgear requirements compared to more complex networks, but the 8-hour UPS requirement necessitates careful selection and integration of suitable battery technology and monitoring systems.

Given the lack of a published deadline, potential bidders should prioritize obtaining this information before proceeding. Similarly, the missing CPV codes make it difficult to identify similar tenders and relevant standards, so researching these is advisable to better understand the procurer's expectations.
