Operating in the electricity distribution sector, this tender falls under the services category, with a focus on utilities. The process is currently at the tender stage and follows an open procedure with a contract value of £1,440,000. Interested parties have until 6th June 2025, at 12:00 PM BST to submit their bids electronically in English. The procurement process includes a framework agreement and is above the threshold for significant tenders, indicating the importance of this initiative to improve network reliability amidst asynchronous generation sources. This tender represents a notable opportunity for businesses specialising in network management and those equipped to offer advanced solutions for electrical stability. Ideal candidates include medium to small-sized enterprises that focus on innovative energy solutions and have the capability to deliver high-quality services, as the evaluation criteria balance quality (60%) and price (40%). Companies that can provide distinctive approaches to managing energy networks during outages and fault conditions are particularly well-suited. The contract runs from 1st August 2025 to 31st December 2030, with potential extensions for two additional years, offering long-term growth and development potential for successful bidders within the UK energy sector. ## Notice Scottish and Southern Electricity Networks (SSEN) build and operate networks to best meet customer needs using the most efficient and flexible techniques possible. To do this, we have introduced Flexibility to help manage our network in the optimal way. The primary use case for Flexibility Services has been the economically efficient deferral of network reinforcements to manage thermal constraints. A Stability Service is a different kind of Flexibility Service that does not fall under the typical standard flexibility services as it provides network stability as opposed to managing a thermally overloaded network asset. Network stability has historically been provided by synchronous generators such as gas turbines; however, in regions where more asynchronous generation is present, network stability becomes problematic. This is due to the lack of an inherent capability to provide stability in intermittent generators such as wind farms. The Western Isles network is an example of a region where we need an alternative source of stability during planned outages and fault conditions. To address this requirement, SSEN are tendering for the provision of a Stability Flexibility Service for the Western Isles.
