  • Coordinate with the grid development team and act as the key interface with DNOs and TOs through construction.
  • Review detailed design submissions from contractors and manage technical RFIs.
  • Support testing and commissioning, coordinating teams and contractors to safely energise and hand over assets to Asset Operations.
  • Assist the Project Manager with inputs to schedules, risk registers and budgets.
  • Support the Senior Project Engineer in reviewing operations and maintenance documentation.
  • Support electrical due diligence for projects [Employer hidden] is acquiring.
  • Review transmission and distribution connection offers, assessing risks and delivery timelines.
  • Liaise with developers, TOs and DNOs to understand connection status and delivery programmes.
  • Review single line diagrams (SLDs) and general arrangement drawings prepared by developers to ensure technical suitability.

Skills, Knowledge and Expertise

  • Electrical Engineering degree (or equivalent) with 5+ years’ experience in the GB electricity industry in a technical or grid-focused role.
  • Strong commercial awareness and a solid understanding of grid connections across both transmission and distribution networks, as well as the wider project development lifecycle.
  • Understanding of the fundamentals of design of a BESS asset.
  • Good understanding of the G99 end-to-end process, including supporting projects through the pre-commissioning compliance process, and familiarity with Grid Code and CUSC requirements.
