Industry giants are always among the first big business models to adapt to the ever-changing requirements for greener, more sustainable energy consumption.

When it comes to the cereal industry there is a no bigger name than Kelloggs, and with that comes no bigger need than to improve their environmental performance. By looking into how they continuously adapt to ongoing greenhouse gas emissions, reduction of energy and water use and their commitment to safe deposit of waste to landfill sites, Kelloggs choose to become the industry leader in green solutions to their processes.

So upon calling on Positive Energy Solutions to fulfill their drive for a greener economy, they chose to continue their legacy of excellent service to the planet.

First Steps

The first step for Kellogs was to survey their existing facility in order to identify key actions to implement to reduce their vast energy consumption.

Upon surveying their site and its processes, it was revealed that requirements in voltage optimization would greatly reduce the energy consumption from the Manchester-based facility with a goal to greatly reduce the considerable costs involved in the daily running of the entire factory.

Bringing in the Team

What was ideally required was a single optimiser solution, and with Positive Energy Solutions being the only supplier able to provide such a product, the team were contacted to provide an adequate solution.

By implementing data logging, our team was able to accurately measure consumption and provide baseline figures. Over the course of this process, it was revealed that the Manchester site was suffering from larger loading swings which were found to be totally unsuitable for the most standard forms of fixed voltage optimisation.

Implementing our EMP optimisers, we managed to optimise the voltage utilising a singular piece of equipment, or a localised area or building. This allowed them to be fixed with variable outputs with or without power factor correction if required.

For this special project, our team designed and developed a stabilized voltage tracker optimiser to work on the specific issues whilst achieving the maximum possible energy saving. After installing the unit, further data logging was undertaken to measure the total savings to the company.


The Implementation of the power optimizer has managed to save the cereal giant a huge reduction in energy consumption per year to the tune of 463, 176 KWh for a reduction on
costs to the total per annum of £40, 226.84.

On top of that result is the total reduction of CO2 emissions per annum of 243 tonnes.

The total cost of the project was a figure of £ 71,061.52 with a payback period of just under two years at 21.2 months.

Kelloggs has continued to be at the forefront of green energy adoption since the project and the ECO-MAX system have helped them to achieve 7-8% energy savings on average on top of their £40k savings per year.
