As temperatures crept higher and higher on two of Hong Kong’s hottest nights of the year, something extraordinary happened: Electricity use in hundreds of thousands of homes across the city fell to lower-than-usual levels.
Soaring heat usually means soaring air conditioner use. But in a month when Hong Kong saw its highest ever summer temperatures, 600,000 smart meter customers were invited to take part in CLP Power’s Energy-Saving Missions, and 70% of them actually reduced their consumption.
They were alerted through their CLP apps, or by SMS or email, to save energy in the peak demand hours of 6.30 pm to 8.30 pm and cut their demand by 60MW.
