Unilever’s food production site in Purfleet, Essex has cut its lighting energy consumption by 40% by replacing fluorescent lamps with low-energy equivalents.

Reportedly the biggest margarine factory in the world, Unilever’s Purfleet facility produces Stork, Flora and Bertolli.

T5 fluorescent lighting was chosen as a cost-effective way to improve energy efficiency. To minimise disruption to the busy production schedule, a retrofit solution slotted the lamps into the existing fittings. A plug-in converter Save It Easy from Energys Group enabled 5,160 old-style fluorescent lamps to be replaced with new-generation T5 equivalents.

As a result, Unilever’s Purfleet site is set to slash its lighting energy consumption by 40%, saving 529,476kWh of electricity every year – an estimated cost saving of £60,370 a year, as well as making an annual carbon saving of 284.34t of carbon dioxide.

“The substantial cost savings netted by Unilever as a result of the lighting upgrade mean the project is set to pay for itself in just one year and nine months,”​ says Energys’ md Kevin Cox.
