National Grid Ventures (NGV) is a newly formed global part of NG plc. Our role and influence includes providing security of supply, reducing customer’s bills through our interconnectors, and providing accurate and safe metering services, so it’s essential that it’s continually evolving, advancing and improving. Furthermore, the business is growing, with currently an additional three electrical interconnectors being at either design or build phase.

About the role

NGV High Voltage Direct Current (HVDC) Interconnectors link to other countries’ transmission systems to increase the diversity and security of energy supplies, facilitate competition in the European market and help the transition to a low carbon energy sector by integrating renewable sources.
We already link Great Britain with France and Great Britain with The Netherlands. We have three more in the development linking Great Britain with Norway, Belgium and another with France.

Each interconnector has a dedicated operational team who design, construct, operate and maintain the interconnector. At the Converter station the AC power is converted to DC power at High voltage and a HVDC team typically consists of craftsperson’s, craft attendants, technicians, various engineering roles and a Team Leader.

As an Advanced Apprentice HVDC Engineer you will be based at one of the converter stations, currently in Kent, Hampshire, or Northumberland. You will assist with ensuring the continued safe and reliable operation of the HVDC interconnectors through being part of the construction, commissioning and maintenance of assets within the converter station, identifying the requirement to replace existing plant and equipment and providing technical support.
