In June 2011, BC Hydro commenced implementation of its Smart Metering Program, which involved converting every residential property in British Columbia (BC) from legacy metering to wireless technology smart meters. This Smart Metering Program involves replacing existing electrical meters that are now becoming obsolete, with a comprehensive wireless smart metering system. In total, BC Hydro has installed 1.9 million smart meters to improve service and reliability for 4 million customers in the province.
