HV Power Connections for Commercial Growth

Whether you’re increasing site demand, delivering a large-scale energy scheme, or powering high-capacity EV infrastructure, TriEnergi specialises in high-voltage (HV) grid connections designed for performance, resilience and future growth.

As a NERS-accredited Independent Connection Provider (ICP), we deliver fully compliant 11kV connections, new substations, transformer installations and contestable works — removing the complexity of dealing directly with Distribution Network Operators (DNOs) and providing seamless access to both low- and high-voltage networks.

From initial feasibility and capacity applications through to design, installation and energisation, we manage the entire HV connection process — ensuring faster delivery, scalable infrastructure and long-term network reliability.

Our HV (High Voltage) connections are specifically engineered for large‑scale operations that demand robust, high‑capacity infrastructure. Designed to support larger capacity installations, these connections provide the resilience and scalability required by EV rapid charging hubs, logistics businesses, and manufacturing sites.

  • EV rapid charging hubs: Delivering the power density needed to operate multiple DC fast chargers simultaneously, ensuring minimal downtime and maximum throughput for high‑traffic locations.
  • Logistics businesses: Supporting fleet electrification with dependable high‑capacity connections that keep vehicles charged and operations running smoothly.
  • Manufacturing sites: Providing stable, high‑load connections to integrate EV charging with existing industrial power demands, without compromising productivity.

By leveraging HV connections, clients benefit from:

  • Future‑proof scalability: Infrastructure designed to expand as demand grows.
  • Grid resilience: Secure, compliant connections that meet DNO/ICP standards.
  • Operational efficiency: Optimised load management and integration with renewable energy or battery storage systems.

This makes HV connections the ideal choice for organisations with complex, high‑demand energy requirements, ensuring long‑term reliability and alignment with sustainability goals.

We provide end‑to‑end support covering grid feasibility studies, DNO/IDNO approvals, power upgrade applications, and compliance management. Our expertise ensures that every project — from small commercial installations to large‑scale EV charging hubs — progresses smoothly through the regulatory process.

  • Grid feasibility: Early‑stage assessments to confirm capacity, identify constraints, and optimise connection strategy.
  • Approvals: Liaison with Distribution Network Operators (DNOs) to secure permissions and meet statutory requirements.
  • Connection applications: Managing the technical and administrative process of securing additional grid capacity where needed.
  • Ongoing support: Ensuring projects remain aligned with evolving standards, from initial design through energisation and operation.

By handling the complex regulatory and technical requirements, we reduce risk, accelerate timelines, and give clients confidence that their assets are connected safely, legally, and ready for long‑term operation.
