  • Thank you for this opportunity to present to you today. I’ve been asked to share with you about the Community Energy Association – who we are and our role in furthering integrated action on energy sustainability at the community level. We are BC-based inter-agency collaboration since 1994, incorporated in 2003 as a charitable non-profit. We’ve been promoting community energy planning in BC for over 15 years. First a caution around our name: In BC, we often use our acronym, CEA, but I realize this can be confusing, especially in national gatherings, in light of the Canadian Electricity Assn – one of the Quest sponsors! My apologies in advance for the CEA acronym on some of my slides.
  • CEA is a collaboration of many agencies … UBCM, PIBC, energy and transit providers, and recently individual local governments. We now are inviting local governments to join, to help provide leadership across the province. Opinions in this presentation are that of the presenter only and doe not necessarily reflect each member.
  • Challenges at the community level – 100 year decisions, planning for the ‘old future’ or the ‘new future’ All the changes are within the lifespan of the assets that we’re making decisions on today
  • A boom in interest in DH systems around BC 3 existing community systems Revelstoke and North Vancouver the first community owned systems in BC At least 10 more under serious consideration

    Growing Interest in DE Around BC
  • 6. Work Completed
    • The Community Energy Association (CEA) conducted a district energy prefeasibility study of Township of Langley in March – April 2009.
    • A district energy prefeasibility study is an initial survey of district energy options within the Township, in order to determine the potential scope of district energy
    • CEA conducted a review of existing and projected energy demands across the Township, a review of potential energy sources , a visit to potential district energy sites, interviews with key people, a discussion with a panel of experts and identification of best project opportunities
  • 7. Designing for District Renewable Heat
    • Encouraging mixed-use higher density urban development;
    • Reducing the energy input required for a given level of service;
    • Matching the type of energy with its use;
    • Managing surplus heat across applications and sectors;
    • Avoiding waste by converting to energy;
    • Integrating on-site renewable sources of energy;
    • Use of grid energy as a resource to optimize the overall system and ensure reliability
  • 8. District Heat Opportunities
    • Applying filters of density, variability, and availability…
    • 4 areas where the heat demand looks promising for renewable district energy
  • 9. Energy Everywhere
    • Different energy options for different areas…matching the source and system to the local availability and need
    • Distributed building-scale renewable heat, not inter-connected but widely deployed
  • 10. Poor Not a good candidate unless site floorspace density increases Rabtherm, sewage lift station New Fair Poor Carvolth potential urban village Possible Compact, single-use, near large sewage lift station. More nearby heat demand opportunities likely needed to justify a DE system Sewage lift station New Poor Good Potential high density Willowbrook development Possible Energy density for space heating and hot water seems too low, although some individual buildings may show an opportunity Wastewater treatment plant Existing Good Poor Northwest Langley Industrial Area Good Mixed-use high density town centre redevelopment. New nearby large lift station about to be built should be designed to be “heat recovery ready” Sewage lift station, & possibly ice arena waste heat, OR wood pellets New Fair Good Downtown Aldergrove potential densification Good Compact, mixed-use, next to large private ice arena Ice arena waste heat with borehole, OR geoexchange New Fair Good Colossus potential mixed-use development Good High demand, new construction, new large sewer line nearby Potential combination of Rabtherm, vertical loop geoexchange, & wood pellets New Fair Good Yorkson Town Centre Good Institutional core of demand with carbon neutral requirement, few buildings to connect up Vertical loop geoexchange Existing Good Good Murrayville Core including hospital lands Overall Notes Best Heat Source Type Heat Stability Heat Density Location
  • 11. Recommendations
    • Approve the development of a Murrayville core district energy implementation plan by staff and/or consultants as a first step towards a Murrayville district energy pilot project
    • Ensure Community Energy and Emissions Plan specifically supports district energy in high-potential areas and building-scale renewable heat in low density areas
    • Allocate budget to proceed with a feasibility study for the Murrayville site including further analysis of ownership / governance options
    • Contact BC Hydro and Terasen regarding financial support for the study
  • 12. Going Further - Recommendations
    • Review policies to support building-scale renewable energy in low-density areas
    • Investigate greenhouse and anaerobic digestion opportunities
    • Provide training opportunities for developers on renewable heat opportunities
  • 13. Thank you
