Interval Meters

Welcome to Toronto Hydro-Electric System's customer accessible interval metered data system.


PowerLens Business is Toronto Hydro’s new online customer portal for accessing interval metering data. The new portal makes it easier to monitor your energy usage and access metering data. It will also provide you with the ability to determine how your facility or facilities use energy, compare electricity usage or demand across multiple locations, and view your minimum, maximum and average demand.


Please note: PowerLens Business only applies if you have interval metering. You can determine whether or not this applies to you by checking page 2 of your Toronto Hydro-Electric System bill. If the first row has a column labelled "Peak kW 7:00-19:00" between Demand kW & Demand KVA, please proceed to register for PowerLens Business.
