Toronto Hydro-Electric System is expanding the Energy-Axis System that it began testing in 2004. Toronto Hydro-Electric System selected Elster Electricity's EnergyAxis System after piloting a variety of technologies and completing a competitive bidding process. The system enables Toronto Hydro-Electric System to collect hourly interval and time-of-use metering data on electricity consumption from apartments, townhouses and single-family residences. The system also has a two-way-controlled mesh network, which has the ability to penetrate most meter rooms, parking decks and foliage in a dense urban environment.

Toronto Hydro-Electric System is committed to fulfilling its obligations under the government of Ontario's Smart Meter Initiative, which is designed to help meet electricity demand challenges in the province. The government of Ontario has established targets for the installation of 800,000 smart electricity meters by Dec. 31, 2007, and the installation of smart electricity meters for all of the more than 4.5 million Ontario electricity consumers by Dec. 31, 2010.
