Holiday Inn Hotel , Chester

Powerdown220 were contacted as a potential supplier, and it emerged that Powerdown were the only company that could supply a single solution to handle all of the specific site issues. Data logging allowed us to measure consumption and provide baseline figures. During this process it emerged that the site suffered from large voltage swings which made it unsuitable for standard forms of fixed voltage optimisation.


In this instance a three stage optimiser with power factor correction was designed to deal with the specific issues identified, and to achieve the maximum possible energy saving. The unit was installed and further data logging carried out to measure the savings.

The installation of the Staged Voltage Tracking Unit has mitigated the problems associated with large voltage fluctuations on site. Holiday Inn have seen a reduction in equipment failures, and associated replacement/maintenance costs as well as reduced electricity bills.

12.5% average energy savings achieved by the ECO-MAX, and savings of £5,837 per year, with a payback of 25 months
