Floating solar panels on a water treatment plant
Around every two years, the city of Windsor measures its greenhouse gas emissions and analyzes them with the aim of reducing them. In 2017, it was found that 38% of the city’s carbon footprint was due to wastewater treatment facilities.
To mitigate the impact of the sewage treatment plant, the city of Windsor aimed to install solar panels to make the facilities almost energy self-sufficient (at 95%) and thereby reduce the city’s carbon footprint. However, it faced a dilemma: there was a lack of available land in Windsor to install as many solar panels.
On the other hand, the water treatment pond, which collects the treated, filtered, and disinfected water, offered an available surface area to accommodate floating solar panels.
The journey with Ciel & Terre and Laketricity could begin. After two years of project development, construction, and installation, the floating solar panels were able to generate electricity for the sewage treatment plant.
