Electrical Design Engineer - HV/LV (BESS / Grid Connection)
📍 Location: Olney, MK46
💼 Type: Contract
💰 Salary: £180 - £240 a day - Open to discussion
About the Role
We are seeking a highly capable Electrical Design Engineer to support the delivery of a major energy infrastructure project, with a strong focus on Battery Energy Storage Systems (BESS) and grid integration.
You will be responsible for delivering electrical design work from concept through to construction and commissioning, working across both low voltage (LV) and high voltage (HV) systems up to 33kV. A key aspect of the role will involve designing how BESS assets connect into the wider transmission network (up to 400kV).
This is an excellent opportunity to gain exposure to grid-scale energy projects and contribute across the full project lifecycle.
Key Responsibilities
Deliver LV and HV electrical designs (up to 33kV) from concept through to detailed design and commissioning
Produce high-quality designdeliverables including:
Electrical layouts
Cable schedules
Lighting and HLV designs
Support the integration of complex systems, including:
Battery systems
Inverters
SCADA
Switchgear
Ensure compliance with UK standards and design governance processes
Contribute to grid connection design for large-scale BESS projects
Key Requirements
Strong background in HV/LV electrical design, ideally up to 33kV
Experience working on BESS, renewable energy, or grid connection projects
Proven ability to deliver technical design outputs and documentation
Experience integrating multiple electrical systems within complex infrastructure projects
Good understanding of UK industry standards and design processes
Desirable Experience
Experience interfacing with National Grid or transmission network operators
Background in large-scale infrastructure or complex energy projects
Exposure to grid-scale BESS or renewable energy developments
Why Apply?
Work on a high-profile, technically complex energy project
Gain hands-on exposure to grid-scale BESS and transmission connections
Be involved across the full project lifecycle - from design through to delivery
Join a forward-thinking team at the forefront of the energy transitionIf you're a technically strong electrical design engineer with experience in HV systems and energy infrastructure, we'd love to hear from you.
