What is being bought

Scottish Hydro Electric Power Distribution plc and Southern Electric Power Distribution plc (SSEN) intends to establish a multi-supplier Framework Agreement for the supply, delivery to site, off-loading onto prepared foundations, installation, preparation for service and commissioning of medium power oil immersed three-phase double-wound primary transformers. The transformers will operate at primary voltages of 33kV, 22kV and 11kV, with power ratings ranging from approximately 1.5MVA to 20/40MVA. Each transformer shall be designed to operate as part of a parallel supply scheme and be capable of carrying full rated load continuously in the event of the loss of a partner transformer. Transformers shall also be capable of operating under reverse power flow conditions. The scope includes all associated equipment required to provide a fully operational installation, including, but not limited to: Cooling systems Tap changers Control and monitoring equipment Transformer protection interfaces Initial oil fill Installation and commissioning services As part of the procurement, SSEN intends to adopt a standardised and modular transformer design philosophy to support a "design once, build many" approach. The objective is to reduce design variation, improve manufacturing efficiency, enhance security of supply and support long-term network investment requirements.

Comparable-procurement analytics

Benchmarked against retained Find a Tender procedures with CPV division 31. The category anchor is Transformers (31170000); this is a deliberately broad market comparator. The comparison is shown at several levels rather than pretending one company or region is always the best benchmark.

Comparison setProceduresReported bids per procedureNamed award suppliersPrice evidence

“Reported bids” is an official aggregate, sometimes reported per lot; it is the closest available competition measure. “Named award suppliers” are winners, not all applicants.

Price-outcome signal

Not enough comparable procedures currently publish both a GBP tender value and a usable lowest-valid-bid value to calculate a responsible price-reduction benchmark. Tenderline deliberately does not infer a saving from named award suppliers or from missing award values.

Transformers shall also be capable of operating under reverse power flow conditions. \nThe scope includes all associated equipment required to provide a fully operational installation, including, but not limited to: \nCooling systems \nTap changers \nControl and monitoring equipment \nTransformer protection interfaces \nInitial oil fill \nInstallation and commissioning services \nAs part of the procurement, SSEN intends to adopt a standardised and modular transformer design philosophy to support a \"design once, build many\" approach. The objective is to reduce design variation, improve manufacturing efficiency, enhance security of supply and support long-term network investment requirements.",
