District Energy System
The biomass-based District Energy System (DES) provides economic and environmental benefits to the City of Prince George. The system takes what was previously considered waste heat from the Lakeland sawmill and transfers it through insulated piping. The DES reduces more than 1,900 tonnes of greenhouse gases per year and currently heats many key buildings in downtown Prince George including:
- City Hall
- The RCMP Building
- The Law Courts
- The Prince George Public Library
- The Prince George Conference and Civic Centre
- The Four Seasons Pool
- The Wood Innovation and Design Centre
- The Two Rivers Art Gallery
- Plaza 400
GENERAL BENEFITS
- Reduces particulate emissions in the city air shed.
- Helps the City and its customers meet greenhouse gas reduction goals.
- Reduces the City's reliance on non-renewable fossil fuels.
- Helps position Prince George as a leader in bioenergy application.
- Helps with energy security and stability.
- Keeps energy-related funds in the community.
- Helps with downtown renewal.
- Generates non-tax revenue for the City.

ECONOMIC BENEFITS
- Provides energy price certainty.
- Generates new non-tax revenue.
- Reduces carbon tax payments.
- Avoids capital costs for future facility upgrades.
- Strengthens industry sustainability through partnerships.
- Is an attraction for businesses.
- Ensures energy dollars remain in our community.
ENVIRONMENTAL BENEFITS
- Reduces total net particulate matter by 100.7 tonnes per year.
- Reduces total greenhouse gas reduction by 1,868 tonnes per year.
- Supports forestry - the mainstay of the local economy - and is more cost-effective to implement than any other potential renewable energy sources.
Biomass
City Council approved the next steps towards developing a wood fibre-based downtown district energy system on June 7, 2010. This system will provide carbon-neutral green energy to buildings in downtown Prince George.
Peaking Backup Energy Centre
The Peaking Backup Energy Centre was completed in 2012 and houses the City's distribution pumps and peaking backup natural gas-fired boilers. These provide hot water to the District during times when Lakeland Mills is shut down for routine maintenance or during very cold weather when there is high demand for heat.
Distribution Piping System
The Distribution Piping System (DPS) from Lakeland Sawmill to the Energy Centre, City Hall, Civic Centre, Coliseum, Art Gallery, and the Four Seasons Pool was completed May 2012 and each building contains Energy Transfer Stations. The City now provides space heating and domestic hot water to these buildings with water heated from the Lakeland Mills energy system. This system burns sawmill residues (woody biomass) with greater efficiency and reduced emissions.
