## Summary

Southern Water Services Ltd. is leading a significant procurement initiative under the project "prj_3727 - Power", focused on the procurement of goods and services relating to Power Generators, High Voltage (HV), Low Voltage (LV) systems, Uninterruptible Power Supplies (UPS), and Transformers. The procurement process is categorised under the industry of electrical machinery and equipment, targeting a vast geographical area across the Southern Water region, including Kent, Sussex, Hampshire, and the Isle of Wight (region: UKJ). It employs a selective procurement method through a negotiated procedure with prior call for competition. The project has reached the award stage, with several contracts having been activated, allowing suppliers to commence works and services under this agreement. The procurement process was initially planned and published in 2023, with key dates including a framework setup in Q3 2023, and several contract signings in March 2025.

This expansive framework creates ample opportunities for various businesses, particularly those specialising in electrical machinery, system installations, maintenance services, and equipment hire. Small and medium-sized enterprises (SMEs) can particularly benefit from this procurement due to the high volume of lots available, where suppliers can bid on one or more lots, ensuring flexibility and scalability of their offers. The framework agreement, which spans 4 years with an optional 4-year extension, can foster long-term growth and stability for businesses willing to ensure resilience and uptime in power supply systems. Companies proficient in project management, design, installation, and maintenance of complex electrical systems would be particularly well-suited to compete and succeed in this procurement venture.
