C150 (2027) Preliminary Market Engagement for the Supply of 110/33 kV Power and 275/110/22 kV Auto Transformers.

NIE Networks intends to establish a Framework Arrangement and appoint up to one supplier plus a reserve to enter into separate Framework Agreements for the Supply of Power and Auto Transformers. The requirement is for Power and Auto Transformers used within the NIE Networks’ transmission network. Each Framework Agreement will be for a period of five (5) years with an option, exercisable entirely at the discretion of NIE Networks and subject to the terms of the Framework Agreement, to extend by a further optional period of up to three (3) years, with a total potential duration of eight (8) years.

It is envisaged that this will be a multi lot procurement exercise consisting of the following lots:

Lot 1 Supply of 110/33 kV Power Transformers

Lot 2 Supply of 275/110/22 kV Auto-transformers

NIE Networks estimates that the total spend under framework agreements could be up to £63 million for all lots over the total potential eight-year duration.

information event to gather insights from the market before initiating a procurement process for Contract C150 (2027) for the Supply of 110/33 kV Power and 275/110/22 kV Auto Transformers

strategy. This PME supplier information event is open to suppliers and is intended to be a

collaborative effort to ensure a robust and successful procurement process.
