Ontario-based utility PowerStream has launched a pilot solar storage program with Sunverge Energy -- to reduce overall power consumption in its service area by 535,440 MWh by 2020. The two companies will prompt adopting rooftop solar and energy storage systems to achieve the ambitious goal.
Rooftop solar panels and Sunverge systems that provide battery-stored power during periods of peak demand will be installed in 20 homes at the outset of the pilot program. All the units will be managed together by the utility to create a Virtual Power Plant (VPP) using Sunverge's cloud-based software. That will allow PowerStream to manage them as if they were a larger solar energy or energy storage facility, except the power will be distributed at the point of load. For those homeowners who choose to participate, the pilot project will not only save them money, it will provide them with greater control over their energy usage.
"This pilot project with Sunverge is a further testament to PowerStream's commitment to cost-effectively deliver cleaner and more reliable power to our 375,000 customers," said Maurizio Bevilacqua, PowerStream Board Chair and Mayor of the City of Vaughan. “The Sunverge systems will allow us to use rooftop-generated solar power more efficiently and reward our customers through significant bill savings."
Ontario closed its last coal plant in 2014 and is now one of the top 5 North American solar markets. In Canada, more than 99% of solar power is generated in Ontario. It is expected to see stronger demand to rooftop solar systems and energy storage systems in the state.
PowerStream's Sunverge systems feature 11.4-kWh batteries, power electronics, and multiple energy inputs in a UL-certified appliance that is controlled by cloud-based software. Installed in a small footprint at individual homes, the batteries will provide additional capacity during periods of peak demand, and reliable backup power during outages. Customers will be able to use more of the power they generate from rooftop solar and rely less on power from the grid, which will translate into significant cost savings under Ontario's new proposed net metering program.
