Job Description

Energy Marshal – New-Build Data Centre Location: Netherlands Sector: Mission Critical / Data Centre Project: New-Build Data Centre Discipline: Electrical / Commissioning / Energy Isolation Role Overview We are looking for an experienced Energy Marshal to support the construction and commissioning of a large-scale new-build data centre in the Netherlands. The Energy Marshal will provide oversight and governance of site energisation, de-energisation, electrical isolation and hazardous-energy activities. The role will work closely with the Construction, Commissioning, Electrical and HSE teams to ensure electrical systems can be safely energised and that isolation and Lock Out / Tag Out (LOTO) processes are correctly implemented. The position requires strong practical knowledge of MV/HV/LV electrical distribution, electrical switching, isolation procedures and commissioning within data centres or other mission-critical environments. Key Responsibilities Oversee and coordinate energisation, de-energisation, isolation and switching activities during construction and commissioning. Ensure effective implementation of the project's Energy Isolation and LOTO programme. Review energisation plans, switching schedules, Method Statements/MOPs, risk assessments/JHAs, permits and isolation procedures. Verify electrical systems are ready and appropriately controlled before energisation. Review and audit contractor and subcontractor compliance with project electrical-safety requirements. Coordinate energy-isolation activities between the General Contractor, commissioning teams, electrical contractors, HSE and operations stakeholders. Review single-line diagrams (SLDs) and electrical-system configurations to understand sources of energy, system redundancy and isolation requirements. Support safe commissioning and energisation of systems including MV/HV/LV distribution, transformers, switchgear, UPS, generators and associated electrical infrastructure. Maintain robust control of multiple sources of hazardous energy during construction and commissioning. Participate in pre-energisation reviews and readiness assessments. Monitor site practices and intervene where energisation or isolation activities do not meet the required safety standards. Support investigation and close-out of issues relating to electrical safety, switching, LOTO and energisation. Experience & Qualifications Electrical Engineering qualification, electrical trade qualification or equivalent relevant technical background. Strong experience in data centre construction and/or commissioning, ideally on hyperscale or large mission-critical projects. Demonstrable experience with MV/HV switching, energisation and electrical isolation. Strong practical understanding of LOTO / Control of Hazardous Energy. Knowledge and practical experience relevant to NEN 3140 and/or NEN 3840. Previous responsibilities as an Energy Marshal, Authorised Person, Senior Authorised Person, Switching Engineer, HV Commissioning Engineer or equivalent would be highly advantageous. Ability to interpret SLDs, electrical distribution architecture, switching sequences and system redundancies. Understanding of arc-flash risks and electrical-safety controls. Experience working alongside General Contractors, electrical subcontractors, commissioning teams and HSE teams. Strong communication skills with the confidence to challenge unsafe conditions or activities. Comfortable working in a fast-paced construction environment with multiple systems progressing through energisation simultaneously.

Core Responsibilities

Oversee and coordinate electrical energisation, de-energisation, switching, isolation, and LOTO activities during construction and commissioning. Review plans and system readiness, coordinate contractors and project teams, audit safety compliance, and intervene or support investigations when electrical safety requirements are not met.

Requirements

Requires an electrical engineering, trade, or equivalent technical background and strong experience in data centre or other mission-critical construction or commissioning. Candidates should have practical MV/HV switching and isolation experience, knowledge of LOTO and NEN 3140 and/or NEN 3840, and the ability to interpret electrical diagrams and challenge unsafe practices.
