Renewable Energy

Rooftop Solar Array

On-site solar generation continues to be an important part of the City’s renewable energy portfolio, providing 6% of all electricity used by municipal buildings in FY22. While the City continues to install solar panels on municipal buildings, space constraints require procuring off-site renewables in order to obtain a 100% renewable electricity supply. Buying renewable energy is the most significant action the City can take in the short term to reduce its emissions. Furthermore, buying from a new, yet to be built, system will have the greatest impact in reducing dependence on fossil fuels.

To this end, Public Works is co-leading a cross-departmental initiative to procure a 100% renewable electricity supply for City operations. The City is actively evaluating proposals to procure from new renewable energy development projects that are expected to come online in the next two to three years. The City is reviewing proposals for financial feasibility, climate, environmental and social impacts and other key factors to ensure optimal outcomes.
