Omnia Projects were engaged to provide Front-End Engineering Design (FEED) support for a new 275kV cable circuit, enabling a 300MW Battery Energy Storage System (BESS) connection to the National Grid Electricity Transmission (NGET) network at Stalybridge 275kV Substation.
FEED’s deliverables
- The scope of Omnia Projects’ HV cable design team included:
- Identification of a feasible cable route following cable route walk.
- Confirmation of existing services crossing along the cable route based on the route walk, the hazard plans and the GPR survey information.
- Ampacity calculations utilising CYMCAP software for worse case or summer vs. winter load and installation parameters when provided.
- Multiple HV cable crossings assessments, i.e. 4x 275kV cable circuits crossings, 4x 132kV cable circuits crossings and 2x 25kV cable circuits crossings utilising CYMCAP cable crossing module or based on worst case assumptions.
- Cable sizing and specification following the thermal assessment of all scenarios.
- Production of associated 400kV cable route layout, cable crossings & typical sections.
