## Summary

The tender process initiated by Northern Ireland Electricity Networks for the provision of construction, refurbishment and restringing of transmission overhead lines is now complete. This procurement focuses on works in the electricity sector, specifically the construction of electricity power lines (CPV code 45231400), and aims to cover various locations throughout Northern Ireland. The procurement followed a selective method, specifically a negotiated procedure with prior call for competition, and has resulted in active contracts for the lots titled "Rolling Programme Works" and "Transmission Project Works," with a combined value of £222,800,000. Notably, the agreements were signed on 8th July 2025, culminating a process aimed at setting up framework agreements covering a potential duration of up to eight years, taking into account its extension options.

This tender offers significant opportunities for growth, especially for businesses experienced in the electricity infrastructure sector. Companies, particularly those specialising in large construction works, asset replacement, and emergency response services, may find this tender highly beneficial. With the framework agreement process involving multiple suppliers, large enterprises and SMEs alike can benefit from participating, as evidenced by the involvement of firms like Circet (UK) Limited and Grid Team Services Limited, among others. The scoring criteria for selection were based on a combination of quality and commercial value, suggesting that competitive and well-structured bids are favoured. The procurement's expansive scope, covering major infrastructural work, positions it as an opportunity for robust business development within the sector.
