Summary
Machine-generated summaryTenneT TSO GmbH intends to award a framework agreement for insulating medium checks on oil-filled and alternatively filled components, including extra-high-voltage transformers, auxiliary (own consumption) transformers and compensation coils belonging to TenneT. The place of performance is Germany, where TenneT operates its electricity transmission network. The procedure is multi-stage: interested companies submit a participation request first, without tender documents. Access to the tender documents is restricted and requires signing a confidentiality agreement (NDA), which must be sent to the contracting authority by email. After a plausibility check, access to the offer documents is granted, and only selected bidders meeting the qualification criteria will later be invited to submit offers.

One dot per award, on the day it was signed, sized by its value. A ring is an award with no published value.
