Pickering, November 12, 2021 – A new microgrid community in west Pickering is giving new homeowners more choice and control over their electricity production and consumption.

The coordinated use of solar panels, electric vehicle chargers, and energy storage will let homeowners save money and reduce emissions while demonstrating how microgrids can defer investments in traditional electricity infrastructure.

The Independent System Electricity Operator (IESO), Opus One Solutions, Elexicon Energy and Marshall Homes have partnered to create the Altona Towns community of 27 homes that comprise a fully integrated microgrid. With about 35,000 new residential homes built in Ontario each year, the project will demonstrate how microgrids can benefit homeowners while reducing the amount of electricity needed from the grid, helping make the provincial electricity system more affordable for all Ontarians.

Many communities across Ontario are increasingly looking at emerging technologies in the electricity sector to achieve economic and environmental goals. Funded in part by the IESO’s Grid Innovation Fund this project will demonstrate how communities, local hydro companies and developers can work together to create cleaner and more energy-efficient housing developments.

For residents living in the microgrid community, the use of solar panels and battery storage will allow them to reduce energy costs by supplying their own power needs. It also can provide another option to improve the resiliency of the local electricity grid when faced with extreme weather, providing backup power if there is an outage.

Insights and lessons learned from this pilot will help inform future system planning.
