Since 2001, we have been advising our customers on how best to manage their power systems to meet the demands of the processes it supplies. Working together, our engineers can integrate into your organisation and develop solutions to solve your most technical needs. Our specialised studies can ensure you continue to deliver this quality power supply now and long into the future.

Some of our most popular solutions include:

  • Power Quality
  • Harmonic Filtering
  • Arc Flash Analysis
  • Protective Device Coordination
  • Grid Compliance
  • Load Flow & Short Circuit
  • Feasibility Studies
  • Safety Training


Modern power electronics are susceptible to power supply variations, some can be addressed with a simple fix while others require a more complex design solution. At Premium Power, we strive to project manage your power quality issues all the way from identification through to solution. Our three main areas of expertise in relation to power quality are power quality surveys, power quality monitoring and power quality solutions.


We can assist your business with grid compliance and dynamic modelling when connecting to the grid. We also help with updating networks, and specialise in ensuring wind farms/renewable generation are grid compliant.
We conduct grid compliance studies using the industry recognised software packages. We do this through:

  • RoCoF studies
  • Load flow and reactive power curves
  • Fault ride through studies
  • Frequency response and dynamic analysis
  • System modeling and data capture
  • Harmonic studies of network and generation technologies
  • P28 voltage dip and flicker studies


Isolating faulty components in a power system will help prevent serious power faults. The purpose of a protective device coordination (PDC) study is to model, assess and produce recommendations that will ensure as far as possible so that in the event of a fault the protection device closest will operate first, thus limiting downtime to this part of the system.

In order to ensure these protective devices operating in the correct sequence we look at the characteristic curves of breakers and fuses and ensure that they do not overlap inappropriately. Having completed this analysis we may propose adjustments to the settings of the circuit breakers and the types of fuses. It is possible at this stage we might include an electrical safety perspective.

PDC studies are an invaluable exercise in ensuring an electrical system operates to the required standard of reliability. Any electrical system will over time face new demands and requirements. Any significant changes to a site may impact on the behavior of protection coordination and need further analysis and adjustments.

Arc Flash Hazards & Risk Assessment for Gas Turbine Power Station
The Challenge

This plant had a corporate requirement to assess arc flash hazards. Compliance with technical company standards was required with respect to specific corporate methodology. The facility required electrical risk assessments to be produced to ensure work is carried out in a safe manner and electrical safety training was required for operative staff.

The Solution

We delivered a comprehensive arc flash report detailing the incident energy levels at all the locations in the plant using SKM power tools software package. All of the electrical equipment at various voltage bands were assessed under a range of different switching scenarios for their short circuit withstand capability. Task and location-specific risk assessments were produced to the highest standards. A full electrical safety training programme was rolled out among operators.

ESB power quality
case study
ESB Networks - Grid Power Quality Solution
The Challenge

ESB Networks is the Distribution System Operator in the Republic of Ireland. They needed help supplying and supporting a country wide power quality and power monitoring solution. 10 years on and we are still maintaining and managing the network, which of this size has presented unique communication and configuration challenges.

The Solution

We integrated a large number of metering devices into the PMS. This gave us the ability to measure and monitor EN50160 and grid code compliance across a huge number of sites. We have supported ESB Networks in customising the system to address many challenges.
In recent years the dramatic increase in penetration of renewable energy has placed new and challenging demands on ESB Networks. In 2012 we worked together to write a software system that would allow powerful reporting and analytics of the network. This software solution was delivered on time and within budget and has been expanded since to include the monitoring of many advanced grid performance attributes.

case study
Kinsale Energy Ltd - Electrical Safety & Maintenance Review
The Challenge

Kinsale Energy Ltd wished to improve its overall system of safety at its offshore and onshore gas facilities to meet corporate requirements and update standard operating procedures. In Ireland, work offshore is governed by the Safety, Health and Welfare (Offshore Installations) Act, 1987 which specifically states that an offshore installation must have its facilities, equipment and materials maintained to protect persons employed on the installation against dangers arising in relation to their work. The project presented its own challenges due to its location at two platforms 50km at sea on the west coast of Cork – all travel to the site was via helicopter. As part of the prerequisite operating procedures, all our team underwent Helicopter Underwater Escape Training (HUET) which involved completing simulated escapes under water and engineers wore survival suits while travelling to Kinsale Energy platforms.

The Solution

As part of the study, prospective arc flash incident energies were calculated at all electrical panels. Electrical task-based risk assessments completed by us identified the hazards. Recommendations made within the risk assessments were used to further develop the system documentation and procedures. Staff were then trained in risk management when working on energised electrical panels and learned how to reduce the likelihood of accidents occurring.
Labels identifying the worst-case incident energies were printed and attached to all electrical panels. Having completed the arc flash awareness training, employees are now competent to interpret the information contained on these labels and determine the level of risk faced when completing a task. Staff now know to introduce mitigation techniques to reduce the likelihood of an accident occurring and select appropriate PPE to protect them in the event of an arc flash incident.

earthing study
case study
Earthing Study - Gas Terminal Co. Mayo
The Challenge

The Terminal was constructed on an excavated bog. The majority of the terminal site was constructed on bedrock which is not conducive to a suitable earthing system. Earth grids were therefore installed in bog soils adjacent to the terminal site but at a distance away from switchrooms. We had to determine if the earth grids would create dangerous touch and step voltages during electrical faults.

The Solution

We conducted a detailed analysis of the earthing grids at the terminal site. A software simulation was developed that reflected the characteristics of the soil and the copper conductors placed in the ground at the terminal site. The software model was utilised to analyse the touch and step voltages that would be observed during faults.
