Copeland Borough Council


Copeland Borough Council is extremely passionate about sustainability and encourages individuals and communities to contribute to the environments’ sustainability rather than its deterioration.

By means of making their own contribution to the environments’ sustainability, Copeland Borough Council turned to Powerstar to implement voltage optimisation into their sustainability management scheme.


Formed in 1974, Copeland Borough Council in Cumbria is based in the most north-western county in England.

Cumbria boasts some impressive statistics, such as having the lowest crime levels in the England, having the deepest lake (Wastwater), and the highest mountain (Scafell Pike). One further statistic which the Council aims to be known for is their dedication to improving the carbon footprint of Cumbria.


The Council’s voltage was being supplied at 243V, in line with the average voltage throughout the UK. The council was actively researching voltage optimisation systems to determine the best option for their site.

It was important for the council to source a reliable and secure system that could demonstrate high efficiency and low failure rates over a high number of local authority installations.

Powerstar, a UK manufactured system, with proven results in head to head trials against competitors and with over 4,500 installations worldwide provided the ideal system for the council.


The Powerstar team delivers a turnkey solution and adopts an acclaimed project led approach to ensure optimum savings are achieved for each site.

After a full site survey, it was determined that the installation of Powerstar’s unique voltage optimisation unit would reduce the Council’s incoming voltage by 7.3% to 225V.

By reducing voltage levels, Powerstar lowers the operating temperatures of motors thus, in addition to energy savings, also decreases the power consumption from a given building, effectively extending the life of electrical components and reducing maintenance costs.


The installation of Powerstar at Copeland Borough Council will produce an energy saving of 59,760 kWh per annum, and as a result of this, 32.6 tonnes of carbon dioxide will be saved each year. This annual saving is the equivalent to the CO2 produced in driving 98 thousand miles in a car or heating a home for 5 years.

Such a saving will most certainly gain Copeland Borough Council recognition of their sustainability management methods, and continued efforts to reduce their carbon footprint.

Councillor Allan Holliday, portfolio holder for the environment and sustainability said:

“The voltage optimisation system is a great example of a change that we can make which helps the environment and save money without any effect on the services we provide. By making this change, we can reduce the amount of energy we use in the building, yet still operate all of the same technology and systems that we currently use.”
