The City has mandated the installation of renewable energy systems on all City buildings, where feasible, by 2020. Over the past 20 years, more than 50 renewable energy systems have been installed on City buildings and properties.

Renewable Energy Policy for City Buildings

Over the past 20 years, more than 50 renewable energy systems have been installed on City buildings and properties. Using solar photovoltaic (PV), solar thermal, geothermal and biomass, these and future systems will support the City’s environmental, energy security and economic goals.

Over 100 rooftop solar photovoltaic (PV) systems, totaling 9MW have been installed on City-owned buildings, generating clean energy and revenue.

Installing solar PV systems supports two key goals of the Corporate Real Estate Management Net Zero Carbon Plan:

  • 37MW of renewable energy to be installed on City owned facilities by 2030
  • Net-zero emissions in City-owned facilities by 2040

The City continues to install rooftop solar PV systems to generate electricity and offset a portion of the City’s hydro bill.

The City’s first solar PV and energy storage project was installed at Toronto Paramedic Services Station 46. The system offsets a portion of the site’s electricity consumption and provides back-up power in the event of a power outage.

The system comprises of:

  • 10 kW of solar capacity on the south-facing wall and rooftop
  • 27kWhr of stored energy in two Tesla Powerwall batteries

Excess electricity generated by the site is exported to the grid. The City is looking to install similar projects in other City owned buildings. This will help meet the TransformTO Net-Zero Strategy target of 37MW of renewables by 2030.
