RENOLIT Cramlington Ltd


RENOLIT Cramlington Ltd is an international leader in the manufacture of high quality plastic films and related products for technical applications.

The site at Cramlington currently employs around 280 people.


RENOLIT Cramlington Ltd actively look for ways to reduce their energy consumption and adopt technologies that are economically and ecologically viable.

Good sustainability practices are shared across the group with the objective of continuously bettering energy management at the core. By implementing energy efficient practices they have already reduced their energy consumption.

Voltage optimisation was identified as a viable technology to help them achieve further efficiencies, and Powerstar were invited to assess the company’s energy consumption levels and recommend a guaranteed energy management solution which could deliver the desired environmental benefits.


During the evaluation and load analysis of their site in Northumberland, the average voltage was recorded at 238V with the maximum reaching as high as 243V.

As the voltage on site was high but relatively stable the Powerstar team recommended the installation of Powerstar LITE’s across their estate to optimise their supplies.

The first install in early 2016 produced reductions to the annual consumption of 11.7% and provided further reductions to their CO2 emissions by 361.89 tonnes – sizeable contributions to help the business achieve the European Commissions ambitious 2020 eco targets.


The second installation took place in late 2016 with guaranteed savings of 6.2%.

  • Annual consumption saving: 11.7%
  • Annual CO2 savings: 361.89 tonnes
  • Payback: 2.2 years
  • Voltage reduced by: 15V
  • Guaranteed savings: 6.2%
  • Voltage reduced by: 12.5V
