The Impact of Sub-Metering on Condominium Electricity Demand

Working Papers from University of Toronto, Department of Economics

Abstract: Growing concern about the environmental effects of electricity generation is renewing demands for electricity conservation and efficient usage. With a substantial fraction of the population insulated from energy price signals in bulk-metered apartment and condominium buildings, some jurisdictions are considering mandatory metering of individual suites. This study analyses data from a Toronto condominium building to assess the impacts of suite (or sub-) metering. We estimate the aggregate reduction in electricity usage arising from sub-metering to be about 20%. Financial savings to residents are much smaller. We analyze large variations across units in electricity consumption after sub-metering finding that unit characteristics explain much but not all of this variation. We perform both private and public cost-benefit analyses of sub-metering and find that the social net benefits depend strongly on the value assigned to externalities from generation and that net social benefits may often be positive when private benefits to the residents are negative.
