Cummins Power Systems


Cummins Power Systems, a subsidiary of Cummins Inc., is a global leader dedicated to increasing the availability and reliability of electric power around the world. With more than 90 years of experience, its global network of distributors in more than 190 countries delivers innovative solutions for any power need – commercial, industrial, recreational, emergency and residential.

The Problem

Much like iESCo, Cummins Power Systems pride themselves on matching the right control technologies with their client’s power requirements. Power generator business Cummins are “committed to meeting or exceeding clean air standards worldwide”, meaning the reduction of carbon production, and of course cost are important.

Our Solution

iESCo installed powerPerfector iQ technology over the Christmas period to minimise disruption to the running of the site and the iQ was fully functioning in less than 8 hours due to preparation work prior to the shut-down.

The iQ is the fastest, most accurate and precise control technology on the market. The iQ has been designed in response to the increasing risk of greater supply volatility, phase imbalance and increased transients and harmonics due to the multiple renewable feeds onto the network.

The Results

To provide accurate savings analysis to Cummins a Power Quality Analyser (PQA) was installed upstream of the powerPerfector. The location of the PQA was important as to replicate the site meter, which does not see a change in voltage itself. Once the PQA was set up the iQ was programmed to cycle on and off every half an hour. This programme allowed Cummins to measure the impact by comparing the data throughout the day.

We observed an average change in power between the cycles of 9.22kW or 7.34%.

Savings were measured using a FLUKE power Quality Analyser to ensure 100% accuracy.


The Overview

  • 240,667 kWh Saved
  • £29,050 Saved


“Start to Finish, it has been an absolute pleasure working with iESCo throughout the project. The engineers are very thorough at all stages, planning, preparation and installation. The project team are fantastic demonstrating every positive aspect of customer care and delivering all information efficiently.”
