11. Voltage Harmonization Pilot Project

Electrical distribution systems in Canada are designed around a common set of voltage standards to ensure the reliable operation of electrical equipment within buildings. Since electrical substations often supply a large number of diverse facilities, a compromised voltage level that balances the needs of multiple buildings is typically deployed. As a result, facilities can experience fluctuating voltage levels in excess of what is required.

A “Voltage Harmonizer” monitors and controls electricity entering a facility and lowers its voltage to the minimum required level for reduced electricity costs. The benefits of Voltage Harmonizers were investigated at the Art Gallery of Windsor, 400 City Hall Square East, the Forest Glade Arena, and the Capri Pizza Recreation Complex. Among the five buildings, the 400 City Hall Square East facility presented the greatest overall annual savings of approximately $12,000 per year.

A pilot project based on the analysis is being considered in 2021.
