ENERGY GENERATION & RECOVERY 

 

Indication of management commitment (e.g., standard operating procedures; board/executive 
management renewable energy conversion policy, including quantitative goals developed and 
shared with stakeholders)   

 

Internal energy sources evaluated (e.g., biogas, hydropower, heat in wastewater), and/or 
renewable energy sources evaluated on an ongoing basis (e.g., solar, wind, co-digestion)  

 

Recovery of digester gas in a combined heat and power (CHP) system, and boilers in place (for 
process and building heating)   

 

Conversion of digester biogas to electricity and heat, and/or transportation fuel Yes   

 

Solar panels, wind turbines, heat recovery, in conduit hydro, and/or hydroelectric power 
generation systems installed  

Annacis Island Wastewater Treatment Plant Co-Generation System Upgrade: replace existing four, 804 
kW co-gen engines with four, 1.9 MW co-gen engines to improve biogas utilization. Estimated increase 
in electricity generation of 20,000 MWh/year. To be completed in 2018. 

Iona Island Wastewater Treatment Plant Flared Biogas Utilization: use of all biogas for co-generation 
applications. Estimated savings of 3,166,000 kWh/year (CAD $380,000/year).  Completed in 2016. 

Lulu Island Wastewater Treatment Plant Flared Biogas Utilization:  

Installation of infrastructure to purify and sell biogas to local natural gas supplier under established 
contract. Estimated savings of 9,700,000 kWh/year (CAD $625,000/year). To be completed in 2018. 

Gilbert Trunk Sewage Heat Recovery: construction of a diversion chamber and associated infrastructure 
to divert sewage from new Gilbert Trunk Sewer near Richmond Olympic Oval for the purposes of heat 
extraction. Estimated savings of 35,000,000 kWh/year in collaboration with the City of Richmond.  To be 
completed in 2024. 

Lions Gate Secondary Wastewater Treatment Plant Effluent Heat Recovery: Developed business case for 
recovering heat from effluent at new facility, to be sold to local district energy system. This upgrade 
allows for 20% less energy consumption, and an 80% reduction in CO2 emissions /year as compared to 
similar wastewater treatment plants in Canada (based on benchmarking data from the National Water 
and Wastewater Benchmarking Institute). Estimated savings of 40,100,000 kWh/year once completed in 
2040. 

Metro Vancouver has committed CAD $4 million in funding to establish the first North American 
Thermal Hydrolysis Processing pilot unit at the Annacis Island Wastewater Treatment Plant, which will 
be used to convert wastewater sludge into mostly biocrude, some biogas and CO2, with practically zero 
solids output.  The biocrude can be upgraded to higher-value transportation fuels such as biodiesel or 
biojet fuel.
