## Summary

Northern Ireland Electricity Networks Limited has completed the procurement process titled "C320 (2025) Supply of 11kV, 33kV, 100kV & 275kV Surge Arrestors," focusing on the supply and delivery of surge arrestors across Northern Ireland. The procurement falls under the main category of goods within the electrical machinery industry. The contracts, initiated through a selective procurement method, have transitioned from tender to award stage as of 19th June 2026, with awards signed on 11th June 2026. This procurement process was driven by a negotiated procedure that involved prior competition, covering locations within Northern Ireland.

This procurement offers various growth opportunities for businesses, particularly those with industry expertise in electrical components, surge protection equipment, and consumables for electrical infrastructure. Companies such as TE Connectivity Solutions GmbH, a large supplier, and Ensto Renley Limited, a small or medium enterprise (SME), have successfully secured contracts, indicating diverse opportunities for different business sizes.
