Our team of experienced electrical and power system engineers use ETAP and SKM modelling software to construct a digital twin replica of your electrical network in order to optimise the design, monitoring, control, and automation of your power system.

Depending on the outcomes or information you require we can conduct any number of the specialised studies we offer.

  • Load Flow & Short Circuit Analysis
  • Protection Device Coordination
  • Unit Protection
  • Harmonic Analysis
  • Transformer Inrush
  • Transient Stability
  • Arc Flash Analysis
  • Feasibility Studies
  • Reliability Analysis
  • Grid Connection Studies
  • Power Management

Our work is conducted in line with IEC and other appropriate standards. Combining our network modelling software, SKM, ETAP or DIgSILENT and the experience of our team allows us to provide clients with bespoke analysis solutions.

Our work doesn’t stop once we issue you with your report. We can act as Project Managers for the implementation of a protection setting upgrade program. Our project management service includes:

  • Verifying the settings on site match what is currently recommended in the power system report.
  • Engaging with electrical contractors to perform injection testing of circuit breaker trip units and verifying results.
  • Developing a system to track and manage all electrical protection settings from that point forward, including a maintenance mode settings program.
  • Cater for any retrofit projects / system upgrades, recording when settings are implemented, keeping the live electrical model upto date.


Our arc flash study is based on the regulations and recommendations set out in the IEEE 1584 standards.  The purpose of the study is to identify the maximum incident energy and arc flash boundary at every point of the network. Understanding the magnitude of the hazard is a key starting point when preparing control measures to protect workers. Our experience and expertise with arc flash studies and related works is widely recognised in Ireland, the UK and internationally and we are used across multiple industries.


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 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 operate 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.


The configuration of the electrical distribution system changes over time to meet the needs of the various generation, manufacturing and operating processes. The alteration of an electrical distribution system configuration results in the operating characteristics and specification of the network changing.
For new and expanding facilities it is necessary to determine the predicted electrical load growth rate and investigate suitable connection points for future loads. Identifying suitable locations in the electrical network can be utilised for connection of electrical loads, identifying weak points, spare capacity and prediction of energy loss. This will allow the creation of a technically feasible strategy for the successful expansion of the network.


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


Transformer differential protection is a popular choice for protecting critical transformers in power systems, especially when high sensitivity is required to detect internal faults at an early stage. It’s commonly used in substations and industrial facilities to safeguard transformers and maintain power system reliability. The benefits of Differential protection are:

  • It can detect even small fault currents and, therefore, provides better protection against incipient (early-stage) faults within the transformer. This sensitivity is particularly useful for detecting winding faults and incipient problems that might develop into more severe issues if left undetected.
  • Once the relay detects a fault or an abnormal condition, it sends a trip signal to the circuit breaker to disconnect the transformer from the system. This rapid tripping helps prevent further damage to the transformer and minimizes system disturbances.

Calculating the potential arc flash risk at the 15MW wind farms 20KV and 690V equipment.

case study

PepsiCo sought to make their production plant in Cork a centre of excellence, where industry best practices were exercised to be used as a benchmark for their other locations. We carried out a review of the electrical distribution network on site for reliability and safety and to address any issues found.

grid connection
case study

Working directly with a global multinational data center client we were able to develop comprehensive power system models in order to ensure they were compliant with local TSO grid connection requirements.

feasibility study
case study

A client needed a diesel generator that could be connected to the existing electrical distribution network to ensure that production could continue on the loss of mains power supply. The feasibility study also included the front-end design of the upgraded network.
