    Brief

    NIE Networks is conducting a Preliminary Market Engagement (PME) to gather supplier insights before launching a competitive procurement for power transmission equipment. The opportunity involves establishing framework agreements with up to one primary supplier plus a reserve for the supply of transformers to NIE Networks' transmission network. The procurement is divided into two lots: Lot 1 covers 110/33 kV Power Transformers, and Lot 2 covers 275/110/22 kV Auto-transformers. Each framework agreement will run for an initial five-year term with an optional three-year extension, providing a potential eight-year duration. The estimated total value across all lots is up to £63 million over the full eight-year period. This PME supplier information event is open to interested suppliers and aims to assess market capabilities, identify potential solutions, and develop an effective procurement strategy. Suppliers are encouraged to participate in this collaborative engagement to understand requirements and inform the upcoming procurement process.
