A team of engineers’ new oil recycling process is expected to help a network power operator save around £32 million.
Electricity North West is the only network operator with a dedicated oil reprocessing plant in the UK.
The facility recycles 1.5 million litres of oil – enough to fill four swimming pools every year – which is the used to insulate and cool transformers.
The new oil recycling process is being used to extend the life of high voltage transformers which provide power to thousands of local homes and businesses as well as keep costs down for consumers.
Project Manager Paul Marshall said: “Transformers are essential parts of power networks that change the voltage of electricity so that it can be safely delivered to homes and businesses.
“Research shows that recycling the oil they use in this way can extend the life of a transformer by 10-15 years. This new approach will save around £32 million over the next six years – savings which will help the environment and help keep bills down for our customers.”
