What We Do

The design process includes:

HPE has extensive experience of providing designs for electrical networks (Utility and Private Wire) from 400kV to Low Voltage.

  • Fault Level and Load Flow Studies
  • The Specification of Switchgear
  • The Specification of Protection and Control schemes
  • The Sizing of Current Transformers
  • Cable Sizing
  • Sizing of Battery Charges
  • The Design of Substation Housings and Foundations
  • Interfacing to SCADA Systems
  • Protection Grading Studies
  • Cable Route and Trench Profile Drawings
  • Legal Drawings depicting New Easements and Leases

Correct operation of circuit breakers during instances of network faults will minimise the extent of an outage, damage to cabling and switchgear and possible injury to personnel.
Using the NEPLAN software we provide fault level and protection discrimination studies for new and existing networks.
Existing Networks
The Electricity at Work Regulations places various requirements on duty holders in relation to electrical systems. Having an up to date protection study is relevant to various regulations to maintain a safe system.
A Protection Study Audit will ensure the protection system operates as required during fault conditions.


We pride ourselves in the production of efficient and economical designs, which consider the safety of people, equipment, livestock and the environment.

At HPE we work seamlessly between disciplines allowing the earthing design to be completed in concurrence with the structural, civil and electrical designs. This results in an earthing system which considers all aspects of the design and allows for a timely and cost effective delivery.


Therefore a safe, resilient and secure electrical power network is critical to minimise interruptions, damage and losses.

With our broad range of knowledge and experience of electrical power systems we offer the following services:

  • Electrical Network Design
  • Protection Studies for new and existing networks
  • Earthing Measurements, Earthing System Design and Testing
  • Power System Studies e.g. Load Flow, Short Circuit Calculations, Transient Stability Studies, Harmonic Studies


Using the NEPLAN software we provide a comprehensive range of power system studies:

  • Load Flow and Fault Level studies
  • Sizing of Harmonic Filters
  • Transient Stability Analysis
  • Motor Starting calculations
