As renewable energy integration increases, so does the need for faster and optimized substation engineering, designing, installation, and commissioning. With supply chain constraints growing, EPENAM offers unmatched solutions for EPCs, contractors, and installers. Recently, we provided secondary engineering services to a major EPC in the UK for their BESS power evacuation loop-in-loop-out substation. The Bramely BESS features a 132 kV substation with three line bays: two line-in-line-out with the utility grid and one towards the BESS transformer.
Key Issues
Renewable integrations have necessitated smaller power evacuation substations that do not fit traditional EPCs and installers’ financial models. Hiring new resources incurs high overhead costs and liabilities, with limited future vertical utilization options. Engaging existing resources for these substations increases operating costs and risks bottlenecks for concurrent larger projects. Bramely faced a similar issue, where HVTD Ltd. sought a cost-effective solution for a complete secondary design and engineering package for their 132 kV BESS substation.
Solution
- GA – Genral Arrangment
- LA – List of Apparatus
- CD – Circuit Diagrams
- WD – Wiring Diagrams
The panel engineering included relay and control panels, metering panels, marshalling kiosks, CT and VT boxes, and other allied services. These panels featured protection relays from major vendors including Siemens, GE, and Arteche. Major protections included:
- Main line differential using Siemens 7SL86
- Backup protection using GE MiCOM Agile P145
- Busbar protection using Siemens 7UT86
Additionally, we provided detailed cable core sheets, cable schedules, and cable block diagrams. We also provided interfacing documents for vendor equipment to ease the interfacing process. This included:
- Circuit Breakers
- Earth Switches
- Disconnectors
- CTs and VTs
Conclusion
EPENAM’s highly cost-effective one-stop solution, powered by our experienced offshore resources, enabled HVTD to complete the project well within time and budget, increasing their margins. The quality of the report, timely delivery, and project handling were acknowledged by the customer.
