Inside the P.E.I. energy systems plant, converting waste to energy
The P.E.I. Energy Systems facility has saved more than 300 million litres of fuel oil and 1.6 million cubic meters of landfill space — enough to fill the equivalent of 89 football fields 10 meters deep — over its 40 years of operation in Charlottetown. David Godkin, general manager of Enwave's facility in Charlottetown, says the P.E.I. Energy Systems plant also produces electricity for its internal use and can provide enough energy on the grid to power about 65 small family homes for a year. The plant uses municipal waste, wood and light oil to produce and distribute hot water and steam thermal energy for more than 145 buildings in the city. On May 27, Godkin gave The Guardian a tour around the P.E.I. Energy Systems facility. Processing waste and creating thermal energy locally allows P.E.I. to displace imported oil and reduces greenhouse gases, he said. 'It significantly reduces the amount of landfill space that is required on an Island where space is limited,' Godkin said. The plant plays a key role in the Island's waste management strategy by diverting residual black cart waste, Godkin said. 'Roadside waste collection is delivered to the plant for processing, where it is received and stored on the receiving floor. Operators then mix the waste to achieve a consistent energy content suitable for combustion,' he said. The composition of the black cart waste that arrives at P.E.I. Energy Systems facility demonstrates that Islanders generally support and follow the Waste Watch program when it comes to sorting, Godkin said, though the plant does have the ability to further separate the contents. 'While the plant was built years ago to accept mixed waste, adjustments have been made so that it presently anticipates and handles sorted residual waste materials after the compostable, recyclable, and other 'special disposal' items have been separated out,' he said. The waste is then fed into three combustion units on a timed basis to maintain control over the secondary combustion temperature, Godkin said. 'This process, known as two-stage starved-air combustion, involves both a primary and secondary combustion zone,' he said. Hot gases from the secondary combustion chambers are ducted to a heat recovery boiler, which generates high-pressure steam. Godkin said that the steam is used to produce electricity and hot water and can also be sent directly to the Queen Elizabeth Hospital for use in heating, cooling, domestic hot water and sterilization. 'After passing through the heat recovery system, the gases are further cooled via two economizers before entering the flue gas treatment system,' he said. Enwave has recently announced plans to expand, constructing a new plant that will be capable of processing up to 49,000 tonnes of waste. That's almost twice the capacity of the existing plant, Godkin said. 'The plant will include a new combustion system with improved efficiency and heat recovery, as well as a new emissions control system,' he said. The new plant will also generate high-pressure steam for electricity, hot water for district heating, and steam for the QEH, providing up to 85 per cent of the fuel input requirements of the system, Godkin added. 'The new plant will be a showcase for waste-to-energy and district energy in Canada,' he said. The facility is set to be in operation by 2028.

City under pressure to retrofit four buildings losing connection to district steam heating
The City of London has less than a year and a half to replace that heating/cooling systems in four downtown buildings. According to a report to the Infrastructure and Corporate Services Committee (ICSC), Enwave Energy Corporation, previously London District Energy, has notified city hall of their intent to cease operating most of the medium-pressure steam line in the downtown core by October 31, 2026. In additional to privately owned buildings in the affected area, the steam line services City Hall, the Central Branch of the London Public Library, Centennial Hall, and Museum London. 'The City will need to transition the heating system from a centralized supply of steam to an in-building heating source for affected facilities,' reads the report. Currently, Enwave is investigating if installing temporary boilers would create redundancy and reliability during the notice period until October 2026. 052325_steam line enwave London city hall newcombe Boundaries of steam line to be decommissioned by Enwave (Source: City of London) There is interest from Enwave to install a temporary boiler system along Wellington Street adjacent to the City Hall property, but there are concerns about the noise impacts on the area. A second location near the western terminus of the steam line along Queens Avenue is also under consideration by Enwave. Meanwhile, city staff are considering the feasibility of options to provide heat and humidification to the four buildings. 'Based on our experience, it is likely the total cost to address this issue will exceed $5 million for all affected buildings,' the report warns. 052325_steam line enwave London city hall newcombe London city hall (Daryl Newcombe/CTV News London) Council will have to determine a source of funding to cover the cost of retrofitting the buildings. 'Investigations into feasible options to provide heat and humidification will need to be completed and engineered designs completed before costs or potential impacts to affected facilities can be determined,' the report concludes. 052325_steam line enwave London city hall newcombe Centennial Hall (Daryl Newcombe/CTV News London)

Hefty retrofit bill likely as Enwave plans shut down of more London steam lines
Moving impacted city buildings off steam heat comes with likely $5M price tag: report Image | London District Energy says portions of their steam system thst serve London's downtown core will be decommissioned. Caption: London District Energy says portions of their steam system that serves London's downtown core will be decommissioned. (Andrew Lupton/CBC) The City of London will likely face millions in retrofitting costs as Enwave looks to decommission more of its downtown steam infrastructure, including a line which heats city hall. Enwave, which owns London District Energy (LDE), told the municipality at the end of April that it would shut down most of its medium-pressure steam lines downtown by Oct. 31, 2026. In a report to next week's infrastructure and corporate services committee meeting, city staff said the reason was that sections of the line were becoming increasingly unreliable despite regular maintenance and "could present safety concerns in the future." City councillors will vote to receive the report for information. The move will impact four city properties, including City Hall, Centennial Hall, the Central Library, and Museum London, the report said. Twelve customers overall will be affected, Enwave said on its website. The Centennial House apartment building will also be impacted. This follows the company's announcement last year that it will decommission a separate low-pressure steam line in the core. It's set to shut down by the end of this month, impacting 17 customers, including the Grand Theatre and the city-owned J. Allyn Taylor building at 267 Dundas St. Converting just the J. Allyn Taylor building from steam to in-building boilers cost at least $810,000, the city said. The Grand Theatre faced a similar estimate, and council voted in August to give the venue $400,000 from the Municipal Accommodation Tax fund to help offset the cost. "Based on our experience, it is likely the total cost to address this issue will exceed $5 million for all affected buildings," city staff write in the report. "As the work to provide an alternative to steam heating is unplanned and not included as part of the adopted 2024-2027 multi-year budget, a source of financing will need to be identified for council approval to support the cost of this work." Converting city hall from steam to hot water heating, or hydronic heating, would be difficult, the report says. Doing the same to Centennial Hall would be very difficult, as steam is used directly in the building's heating coils. City staff say Enwave is assessing the installation of temporary boilers during the notice period until October 2026. One could be located on the west side of city hall, which sits near the end of a steam line branch. Feasible options, timelines, and cost estimates will come after a detailed impact assessment. CBC News reached out to Enwave for comment but did not receive a response before publishing. Jones Entertainment Group, which manages Centennial Hall, referred questions to the city. In a statement on the LDE website, the company says it will work with impacted customers to assist in switching to alternative heating sources. The decommissioning process, it adds, will be structured to minimize customer inconvenience and maintain continuity of service. "We have made sure to provide impacted customers within each respective zone with ample notice to switch to alternative heating systems before the onset of the upcoming winter seasons," the statement says. The company says it's completing an analysis of the remainder of the network. "If our assessments highlight areas that pose safety and/or reliability risks, we will take the necessary actions to either upgrade or decommission those sections to uphold the safety, integrity and efficiency of our service delivery to customers," the LDE website reads. No members of city administration were available to comment Wednesday. "There's a high-pressure line. I do not necessarily foresee anything coming up in the future from that, from what Enwave has informed us," Ward 13 Coun. David Ferreira said Wednesday. He hesitated to comment further, as the city is still assessing impacts. Enwave and LDE provides chilled water for cooling and steam for heating to city hall, Centennial Hall, the Central Library, Museum London, RBC Place and the J. Allyn Taylor Building. The current service contract between the city and company dates to 1992. Previous figures on Enwave's website say it serves at least 60 customers, including St. Joseph's Hospital and University Hospital, and operates 10 kilometres of steam pipes. It also operates three kilometres of chilled water pipes, which will not be impacted.
