Scottish Hydro Electric Power Distribution plc and Southern Electric Power Distribution plc (SSEN) intends to establish multi-supplier Framework Agreements for the design, manufacture, testing, supply and delivery of 11kV indoor metal-enclosed primary switchgear for use across the SSEN Distribution network. The Framework will support asset replacement, network reinforcement, customer connections and strategic investment programmes throughout the remainder of ED2, ED3 and the early years of ED4. Current planning assumptions indicate forecast demand of approximately 2,600 switchgear panels over the anticipated Framework lifecycle, although these volumes are indicative only and no minimum volume or value of work is guaranteed. The procurement is structured across four lots: Lot 1: Conventional CT/VT Fixed-Pattern Switchgear Lot 2: LPIT-Enabled Fixed-Pattern Switchgear Lot 3: Conventional CT/VT Withdrawable Switchgear Lot 4: LPIT-Enabled Withdrawable Switchgear The Framework will support SSEN's wider switchgear standardisation strategy, intended to improve affordability, manufacturing efficiency, security of supply, supply-chain resilience, lead-time performance and whole-life asset value through increased standardisation and product rationalisation. Fixed-pattern switchgear remains SSEN's preferred architecture and is expected to account for the majority of Framework demand. Dedicated withdrawable lots have been included to support specific project requirements and future network investment needs. The scope may include, but is not limited to: - 11kV indoor metal-enclosed primary switchgear; - fixed-pattern and withdrawable switchgear assemblies; - conventional CT/VT and LPIT-enabled instrument transformer solutions; - protection and control interfaces; - manufacturer testing and certification; - technical support and engineering assistance; - installation and commissioning support services; - training, warranty and after-sales support; - spare parts and lifecycle support; and - associated software, firmware, cyber-security support and obsolescence management activities where applicable. Applicants may apply for one, multiple or all lots. Framework appointments and subsequent call-off opportunities will be awarded in accordance with the procurement documents.

Design, manufacture, testing, supply and delivery of 11kV indoor metal-enclosed fixed-pattern primary switchgear incorporating conventional current transformer (CT) and voltage transformer (VT) technology. The scope may include associated equipment, technical support, testing, certification, training, warranty, spare parts and lifecycle support services. Renewal: The initial Framework term will be used until 30th June 2035 with the option of 2 x 1 year extension terms.

Design, manufacture, testing, supply and delivery of 11kV indoor metal-enclosed fixed-pattern primary switchgear incorporating low power instrument transformer (LPIT) technology. The scope may include associated equipment, technical support, testing, certification, training, warranty, spare parts, lifecycle support and activities associated with product approval and deployment. Renewal: The initial Framework term will be used until 30th June 2035 with the option of 2 x 1 year extension terms.

Competitive flexible procedure

Utilities

Suppliers will be appointed to the Framework following completion of the competitive procurement process described within the procurement documents. The Framework is anticipated to comprise four lots covering: • Lot 1 – Conventional CT/VT Fixed-Pattern Switchgear • Lot 2 – LPIT-Enabled Fixed-Pattern Switchgear • Lot 3 – Conventional CT/VT Withdrawable Switchgear • Lot 4 – LPIT-Enabled Withdrawable Switchgear Suppliers may apply for one, multiple or all lots. Framework appointments will be made separately for each lot. Framework awards will be made to the suppliers submitting the most advantageous tenders in accordance with the evaluation methodology detailed within the procurement documents. Public contracts may be awarded either directly or following a competitive selection process between the suppliers appointed to the relevant lot, in accordance with the Framework Agreement. Prices may be established through supplier framework pricing schedules, agreed pricing mechanisms, project-specific quotations and/or further competition, as detailed within the Invitation to Tender and Framework documentation. SSEN currently anticipates appointing multiple suppliers to each lot, although the final number of framework suppliers appointed to each lot will be determined through the procurement process and may vary by lot.
