High Voltage Electrical Network

Turnbull were contracted to support Hinkley Point C in complying with their environmental permits, to reduce the number of diesel generators on site.

The 11KV electrical network, designed and built by Turnbull, will power multiple operations and equipment across the Hinkley Point C site, including office blocks and Tunnel Boring Machines. Turnbull are providing their distribution network operator services from a local distributor.

We provided a robust, compliant and commercially acceptable proposal for the works and have since successfully demonstrated buildability and programme acceleration. We have also installed a number of additional substations and the provision of accessible crane power.

This project demonstrates a successful collaboration of all of our key service offerings:

  • Design - Engaging very early in the process to ensure the successful delivery
  • Build - Implementing the design phase on the ground
  • Operate and Maintain - Our internal Electrical, Mechanical and Instrument Team play an integral part in ensuring the systems are running and maintained without interruption

We are extremely proud to have delivered to date, all works Lost Time Injury (LTI) free. In addition, Turnbull have also:

  • Provided a racking solution to save on civils construction
  • Sequenced work to minimise outages eliminating disruption to end users
  • Integrated in-house relationships with the Senior Authorised Person Team
  • Maintained close interaction with our Tier Two supply chain partners
  • Challenged philosophy for best practices

"Your understanding of all the systems here at HPC are second to none, no corners are cut under any circumstances and a professional and patient manner is always maintained by you and the team. The quality of work undertaken by the installation team is again fantastic and the attention to details in what they deliver has been noticed by all."
