Heat from household waste

As the adage goes, one person’s trash is another’s treasure. Our Prince Edward Island district energy plant converts municipal solid waste and biomass (scrap wood from forest harvesting operations) to energy. Not only does this dramatically reduce the volume of waste that ends up in landfill on the island, it’s a clean, low-carbon energy solution. The added flexibility to easily switch between fuel types also enhances reliability and helps control costs.


Queen Elizabeth Hospital

Reliability at the island’s largest hospital

With round-the-clock patient care, hospitals and other health care facilities depend on reliable energy. At the Queen Elizabeth Hospital in Charlottetown, Enwave’s district energy system supplies heat, hot water, humidification and equipment sterilization, keeping critical systems running smoothly and energy costs predictable.

Enwave helps create comfortable environments for students and staff at the University of Prince Edward Island’s campus. District energy is more reliable and cost-effective, especially for energy-intensive buildings like the Chi-Wan Young Sports Centre, a massive facility with swimming pools, ice rinks, a cafeteria, day care and fitness center.

The environmental benefits of district energy add up, with lower emissions that maintain air quality and a 90% reduction in municipal landfilling volume.

145 buildings served – and counting

  • Operating for more than 30 years on Prince Edward Island
  • 113,400 kilograms-per-hour capacity
  • Fueled by biomass, municipal waste and fuel oil (for backup and flexibility during peak times)
  • C$30 million upgrade, with funding from the Government of Canada’s Low Carbon Economy Fund, will include a larger furnace, heat recovery boiler and air pollution controls
  • Once expanded, will divert an additional 23,000 metric tons of waste from landfill and reduce fuel oil consumption from 20% to less than 5%
