HVPS - Power System Engineering

Power System Engineering

High Voltage Power Services (HVPS) deliver fully engineered and intelligent High Voltage design solutions that integrate utility supply, on-site generation, and standby/emergency systems into a coordinated, compliant, and future-ready electrical network.

From initial concept and network selection through to detailed studies and commissioning support, we ensure your infrastructure is safe, compliant, optimised, and built for operational resilience.

Utility Network Selection & Point of Connection Strategy

We assess and define the most suitable network configuration for your development, including:

  • Incoming supply voltage level selection (11kV / 33kV)
  • Radial, ring main, or dual-fed configurations
  • Firm capacity and redundancy requirements (N, N+1, 2N)
  • Point of Connection (POC) evaluation
  • Load growth modelling and future expansion planning
  • Coordination with DNO / IDNO / ICP stakeholders

Our approach ensures the selected topology balances resilience, capital cost, operational efficiency, and long-term scalability.

Site Overlay & Integrated Power Architecture

We develop a coordinated site-wide electrical overlay that integrates:

  • HV and LV distribution architecture
  • Substation positioning and segregation
  • Transformer sizing and redundancy philosophy
  • Protection zoning and discrimination boundaries
  • Critical load segregation strategies
  • Phasing strategy for multi-stage developments

This ensures seamless interaction between utility supply, on-site infrastructure, and critical systems.

Standby & Emergency Power Integration

We design and model fully integrated standby and emergency power systems, including:

  • Generator sizing and dynamic load acceptance studies
  • Paralleling and synchronisation schemes
  • Automatic Transfer Switching (ATS) strategies
  • UPS integration for critical loads
  • Black-start capability and restoration sequencing
  • Load shedding and prioritisation schemes
  • Resilience modelling under fault and outage conditions

We ensure compliance with relevant standards while delivering practical, operationally robust solutions that maintain business continuity.

Detailed Power System Engineering Studies

Our analytical capability validates performance and compliance across the full network:

  • BS EN 60909 Fault Level Analysis – Verification of equipment ratings and short-circuit resilience
  • Protection Coordination & Selectivity Studies – Optimised discrimination and minimised disruption
  • IEEE 1584-2018 Arc Flash Assessment – Incident energy analysis and PPE categorisation
  • BS EN 50522 Earthing Design & Review – Safe touch and step voltage performance

We identify non-compliances, operational risks, and areas of concern — and provide clear, prioritised improvement strategies.

Technical Due Diligence & Future Capacity Planning

  • Infrastructure appraisal and compliance gap analysis
  • Asset risk and resilience evaluation
  • Future network capacity modelling
  • Load growth forecasting
  • Reinforcement and upgrade strategies
  • Integration readiness for renewables and energy storage
