EFW Private Wire — Concept Studies
A series of Concept Studies for 2x sites for private wire Energy From Waste plants
The challenge
Vital Energi was developing several sites to receive an alternative private-wire supply from nearby energy-from-waste (EfW) plants. Aurora was tasked with developing the initial concepts and assessing loadflow, short circuit levels, protection impacts, automatic changeover operation, break-before-make or make-before-break transition requirements, UPS behaviour and LV backup arrangements.
What Aurora did
We carried out a full concept study for each site, ensuring that the scheme was ready to progress and that many of the usual pitfalls were addressed before gate approval. This included the impact of the alternate supply on the network voltage profile and fault levels under different operating modes, how the break-before-make transition would affect site operations and continuity of supply, post-transfer re-energisation of the network transformers, and constructability of the overall scheme.
