Energy Site Survey

Energy Site SurveyPowerstar provide a free of charge, no obligation site survey for clients who wish to determine the most effective method to reduce electricity consumption on their site.

In addition, we also offer a Power Quality audit and evaluation service to clients to help identify current and potential Power Quality issues and specify the solutions available to rectify these.

The Powerstar site survey is split into three parts:

1) Installation evaluation

The installation section of the survey will look at space restrictions and circuit protection. The information from this part of the survey will be assessed to provide the client with a detailed cost for installation and to inform them where the best location is to position the Powerstar voltage optimisation system on site in order to make the best energy savings.

2) Determine the voltage profile on site

By analysing the on-site voltage profile of a site it enables the correct voltage optimisation system to be specified and the correct optimisation settings to be identified.  A minimum of six spot readings are taken on site to determine where the lowest voltage occurs, the voltage drop on the supply and if there are any voltage issues on the supply.

3) Non-eligible load breakdown

The non-eligible load breakdown identifies the loads within a site that will benefit from reduced electricity consumption following installation of a Powerstar voltage optimisation system and loads within a site that will not benefit from reduced electricity consumption from voltage optimisation.

The non-eligible loads are detailed to the client in the proposal and taken into consideration, along with the voltage optimisation setting, when calculating a kWh energy saving percentage. This percentage is used to calculate the payback period and Return on Investment percentage for the client.





    October 2016: Powering energy savings in South Africa

      Powerstar South Africa, a distributor for market leading energy storage and voltage optimisation brand Powerstar, is currently saving Pick n Pay, South Africa’s second largest supermarket chain store on average over 8% in electricity costs across two of its stores. The company, which is enjoying its largest period of growth since entering the market
