Electrical Engineer (High Voltage) – Grid Interface Design & Commissioning
Job Type: Permanent / Full-Time
Industry: Renewable Energy / Battery Storage
About the Role
On behalf of our client—a leading innovator in the Battery Energy Storage sector—we are seeking a skilled High Voltage Electrical Engineer to join their growing engineering team. This is a fantastic opportunity to work on cutting-edge grid-scale energy storage projects that are shaping the future of clean energy.
The successful candidate will be responsible for the design, integration, and commissioning of high voltage grid interfaces for BESS installations across the UK and Europe. You’ll play a key role in ensuring compliance with grid codes and utility standards while supporting the delivery of technically robust and commercially viable energy storage solutions.
Key Responsibilities
* Design high voltage electrical systems for grid connection (33kV and above), including single-line diagrams, protection schemes, and earthing systems.
* Specify and select HV equipment such as transformers, switchgear, and protection relays.
* Conduct power system studies (load flow, short circuit, protection coordination).
* Interface with DNOs/TSOs to secure grid connections and ensure regulatory compliance.
* Lead or support commissioning activities including FAT, SAT, and energisation.
* Collaborate with internal teams and external contractors to ensure seamless project delivery.
Candidate Profile
Essential:
* Degree-qualified in Electrical Engineering or related discipline.
* 5+ years’ experience in HV electrical design and commissioning, ideally within renewables or grid infrastructure.
* Strong understanding of UK grid codes and interconnection standards.
* Proficient in electrical design software (e.g., ETAP, PowerFactory, AutoCAD).
* Experience with HV testing, SCADA systems, and protection relays.
Desirable:
* Chartered Engineer status or working towards it.
* Experience with BESS or inverter-based technologies.
* Familiarity with international standards (IEC, IEEE).
