Overview We are looking for a Grid Connection Engineer to support the construction and delivery of utility-scale solar PV projects across the UK. Unlike development-focused roles, this position is dedicated to ensuring that grid connection requirements are successfully implemented during construction and that all works meet DNO specifications, grid codes, and project quality standards. You will act as the technical interface between our construction team, ICPs, DNOs, and commissioning engineers to ensure the project is grid-ready and energised safely and on time. Your mission - Coordinate with the DNO/ICP during all construction-related stages of the grid connection process. - Review and validate detailed designs, drawings, SLDs, and protection schemes delivered by ICPs or subcontractors. - Ensure that all grid connection requirements (G99, G100, protection settings, metering schemes) are fully incorporated into construction works. - Provide technical oversight on HV/MV installations, including substations, switchgear, cables, and transformers. - Monitor construction progress against grid connection milestones and ensure readiness for inspections and energisation. - Review method statements, RAMS, and commissioning plans related to grid works. - Attend DNO/ICP meetings, site inspections, and witness tests as required. - Validate as-built documentation and ensure alignment with the approved connection design. - Support the commissioning team during grid compliance testing and energisation activities. - Ensure all works comply with UK electrical standards, DNO policies, and project specifications. Your profile - Degree in Electrical Engineering or related field. - Experience working on the construction of utility-scale solar PV, HV substations, or large electrical infrastructure. - Strong understanding of DNO/ICP processes and construction requirements for grid connections in the UK. - Familiarity with G99/G100, protection coordination, HV/LV installation standards, and grid compliance documentation. - Ability to interpret technical drawings, SLDs, installation specs, and test reports. - Strong communication and coordination skills with contractors, DNOs, and engineering teams. - Comfortable working on active construction sites across the UK. Desirable - Experience with solar PV, inverters, and HV substations. - Knowledge of G99 commissioning and grid compliance testing. - HV authorisation (DNO or private network). - Experience working with plant controllers (PPC), reactive power systems, or hybrid PV+BESS connections. What we offer - Independent work in a committed team - Work in a growing, international company with a start-up mentality - Open and friendly working atmosphere - Flexitime model with core working hours unsolicited application

Overview We are seeking a Commissioning Engineer specialising in utility-scale solar PV projects. This role focuses exclusively on the construction, testing, energisation, and handover phases of solar farms. You will ensure that all electrical systems are installed correctly, tested safely, and commissioned in accordance with project specifications, UK regulations, and DNO requirements. You will work closely with EPC contractors, HV specialists, ICPs, and internal engineering teams to deliver fully operational, grid-compliant solar PV plants. Your mission - Review design packages, installation standards, and commissioning procedures for compliance with project and DNO requirements. - Inspect installation quality for PV arrays, inverters, combiner boxes, transformers, switchgear, cables, and SCADA systems. - Ensure all equipment is installed according to UK electrical standards, OEM manuals, and safety regulations. - Verify HV/MV installation readiness for energisation, including substations, RMUs, switchgear, and protection systems. - Lead onsite commissioning activities for all solar electrical systems, including string testing, IV curve testing, inverter commissioning, HV/MV cable tests, transformer tests, protection relay testing, and SCADA validation. - Coordinate with DNOs/ICPs for energisation, witnessed tests, and grid compliance (G99). - Identify, troubleshoot, and resolve commissioning issues such as communication faults, inverter trips, protection issues, and performance deviations. - Validate system performance, including PR, voltage regulation, reactive power capability, and plant controller operation. - Ensure successful completion of G99 commissioning tests and all DNO‑required checks. - Produce commissioning documentation, test reports, redlines, and handover packages. - Support PAC/FAC milestones and close out punch‑list items. Your profile Skills & Qualifications - Degree or vocational qualification in Electrical Engineering, Renewable Energy, or similar. - Hands-on experience commissioning utility-scale solar PV or large electrical infrastructure. - Strong understanding of HV/LV systems, electrical protection, inverter technology, and solar plant controls. - Ability to read and interpret technical drawings, I/O lists, functional diagrams, and protection settings. - Comfortable working on active construction sites and performing field-based troubleshooting. - Strong communication skills and ability to coordinate with EPCs, ICPs, OEMs, and internal stakeholders. Desirable - Experience with G99 commissioning and DNO witnessing processes. - HV authorisation (DNO or private network). - Familiarity with OMICRON/Megger test kits. - Experience with hybrid PV + BESS commissioning. - Experience with SCADA systems, networking, fiber optics, and data acquisition.
