Interval Meters

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

PowerLens Business


PowerLens Business is Toronto Hydro’s new online customer portal for accessing interval metering data. The new portal will replace the existing MV-Web and make 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.

Existing Toronto Hydro interval metering customers with MV-Web accounts will be transitioned to PowerLens Business beginning in September.

You’ll receive an e-mail in the coming weeks that details next steps on how to register for PowerLens Business

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.



MV Web

Existing Toronto Hydro interval metering customers with MV-Web accounts have now been transitioned to PowerLens Business. All customers must register for a PowerLens Business account by March 31, 2018 to continue to access their data. Historical data currently in MV-Web will also need to be saved by this date.
