The Powerstar team were invited to conduct a site survey to analyse and present the guaranteed savings that the hotel would achieve from the installation of a Powerstar voltage optimisation system.

Powerstar voltage optimisation was chosen to be installed into 9 properties in the PH portfolio.


After a site evaluation and load analysis, the Powerstar team identified that the most effective Powerstar system to match the electrical profile of the site, resulting in quantifiable savings.

Due to it’s unique design Powerstar also provides total phase balancing and also filters harmonics from the supply.

Along with the energy reduction and financial savings, the hotel is benefiting from increased lifespan of electrical equipment due to reducing the over voltage supplied to appliances.

  • Annual financial savings: £16,522


“We worked closely with Powerstar to identify the best options for energy saving within our portfolio. We are extremely happy with savings on all of the installations and the service received.”
