Overview
As an Electrical Design Engineer, you will lead the electrical design of HV and LV power distribution projects across the full project lifecycle — from feasibility and concept design through to detailed design, DNO approval, construction support, and commissioning.
Responsibilities
* Lead electrical design activities for HV/LV distribution networks including substations, underground cable routes, and overhead line interfaces
* Produce and review detailed electrical designs, calculations, specifications, schedules, protection studies, and drawings
* Develop compliant designs in accordance with DNO/IDNO standards, ENA G81, G99, and client specifications
* Undertake feasibility studies, demand assessments, and optioneering for new connections and network reinforcement
* Develop cost-effective, safe, and reliable electrical solutions through value engineering
* Provide technical support during construction, commissioning, and energisation phases
* HV Power, Protection & Earthing
* Design and specify HV/LV substations up to 132kV
* Develop protection schemes, discrimination studies, and interface with DNO protection requirements
* Carry out earthing studies, lightning protection design, and cable sizing calculations
* Produce single line diagrams, substation layouts, and cable routing drawings
* Review supplier and contractor technical submissions and FAT/SAT documentation
* DNO / ICP Interface & Approvals
* Manage the technical submission and approval process with DNO/IDNOs
* Ensure designs are fully compliant for adoption under G81 standards
