District Energy Strategy
Shaping a Sustainable, Renewable Energy Future
Surrey’s district energy strategy is being developed over three phases of growth:
- Initially, temporary energy centres are installed in multiple areas within City Centre.
- As demand for heat energy grows, temporary centres are replaced with permanent centralized energy centres, like the West Village Energy Centre.
- Further investment will take place to integrate the use of large-scale renewable energy sources.
Low Carbon, Long-Term Vision
District energy is an essential component of the City of Surrey’s plan to reduce GHG emissions in new in buildings in support of the City’s 2019 Climate Emergency Declaration and the Official Community Plan target of net-zero GHG emissions by 2050.
Integrated Hot Water District Energy System
The long-term vision includes an integrated hot water district energy system covering the entire City Centre area. Over time, this will include multiple energy centres with a range of low-carbon renewable energy sources, including geothermal energy, biomass from local clean wood waste, waste heat from various sources, and renewable natural gas from the Surrey Biofuel Facility.
Surrey City Energy is currently in the planning phases of a new facility that will use heat pumps to extract waste heat from the sewer system to heat the water in the district energy network. This facility is expected to come online in the next five years. Sewer heat recovery is an abundant, emission-free, and local energy source that can supply up to 70% of heating requirements in City Centre and reduce 480,000 tonnes GHG emissions.

Surrey City Energy has a 30-year plan to build out its City Centre network. It will include three high density nodes, centered around existing rapid transit stations (Surrey Central, King George and Gateway). A separate district energy network will be constructed at each node, and eventually all three networks will be connected to create an integrated system.
