At SBB, several substation projects are currently in planning.

If these projects are realized, SBB will need the following transformers by 2032 (last delivery in 2032):

· Eight overhead line transformers 132/16kV, 21.8MVA, 16.7Hz for the substations Gümligen, Hardwald, Weinfelden, and Cornaux. For further projects that are not yet definitively defined, SBB intends to optionally procure four additional overhead line transformers 132/16kV, 21.8MVA, 16.7Hz through this framework agreement.

· Two overhead line transformers 132-66/11kV, 10MVA, 16.7Hz for the substations Göschenen and Andermatt.

The procurement is advertised in two lots:

Lot 1: Framework agreement for overhead line transformers 16.7 Hz, 132/16kV, 21.8 MVA, 12 pieces (8 pieces plus 4 optional for various locations (Switzerland)

Lot 2: Project: Transformers 16.7Hz for UW Andermatt and Göschenen overhead line transformers 16.7Hz, 132-66/11kV, 10MVA 2 pieces (site UW Andermatt 1 piece / UW Göschenen 1 piece)

The respective specifications describe the requirements for the two lots.
The defined 2 lots can be offered separately and can also be awarded separately by SBB.

For the CFF, certain substation projects are under planning.

If these projects are realized, the CFF will need the following transformers by 2032 (last delivery in 2032):

· Eight overhead line transformers 132/16 kV, 21.8 MVA, 16.7 Hz for the substations Gümligen, Hardwald, Weinfelden, and Cornaux. For other not yet definitively defined projects, the CFF intends to optionally acquire four more overhead line transformers 132/16 kV, 21.8 MVA, 16.7 Hz under this framework contract.

· Two overhead line transformers 132-66/11 kV, 10 MVA, 16.7 Hz for the substations of Göschenen and Andermatt.

The contract is subject to a tender in two lots:

Lot 1: Framework contract for overhead line transformers 16.7 Hz, 132/16 kV, 21.8 MVA, 12 units (8 units plus 4 optional for various sites (Switzerland)

Lot 2: Project: Transformers 16.7 Hz for Ss Andermatt and Göschenen overhead line transformers 16.7 Hz, 132-66/11 kV, 10 MVA 2 units (site of Ss Andermatt: 1 unit/Ss Göschenen: 1 unit)

The respective specifications describe the requirements for the two lots.
The two defined lots can be offered individually and can also be awarded individually by the CFF.
