More than HK$ 1.2 Million in Estimated Annual Electricity Savings
10 Capacitor Banks Installed to Stabilise and Control the Power Flow
Over 15 Years’ Experience in Power Quality Check Ups
Improving Efficiency at the Popular Metroplaza Mall
Metroplaza in Kwai Fong is one of Hong Kong’s liveliest shopping malls with more than 200 outlets and a floor space of 540,000 square feet. CLPe carried out a power quality check-up service on its electricity supply system which prepared the way for significant improvements.
In a series of recommendations and cost estimates, engineers from CLPe proposed installing capacitor banks to stabilise and control the power flow. Metroplaza accepted the recommendations and 10 capacitor banks were then installed by CLPe , resulting in a considerable reduction in electricity costs.
Challenges and Solutions
-
Examining the System during Shopping Hours
The assessment by CLPe was carried out while the shopping mall was in full operation, meaning engineers had to take care not to disturb its normal service and operations. The team of experts drew on their in-depth knowledge and more than 15 years of experience in power quality measurement to complete the assessment without any disruption to shoppers.

Explaining the Investment
A power quality check-up is only the first step to understanding the health condition of a power supply system. What is more important is the follow-up enhancement measures. After the check-up work at Metroplaza was completed, CLPe made recommendations to enhance the efficiency of the system, carrying out simulations based on data to support the recommendation and allow Metroplaza to visualise the positive impact and anticipate a realistic pay-back period, which is around two years on average.
Value Created for the Customer

Saving in Electricity Costs
After the installation of the capacitor banks, the power factor at Metroplaza was significantly improved which reduced the maximum demand charge of its electricity bills. Metroplaza will achieve an estimated saving in energy costs of HK$1.2 million a year.
