Opportunity overview
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.
