Squamish Neighbourhood Energy Utility:Final Feasibility Presentation Prepared for: District of Squamish and Project Sponsors Prepared by: Compass Resource Management Ltd. June 15, 2010
Study Overview • Demand forecast (five target areas) • Analysis of business as usual (BAU) • Screening of many supply options • Detailed analysis of short-listed scenarios • Area A + expansion scenarios (Waterfront and Oceanfront) • Biomass, ocean heat, and natural gas co-generation • Staging and sensitivity analysis
Supply Screening – Shortlist • Biomass • Abundant local resource • One of lowest cost options in screening and greatest GHG emission reductions • Ocean Heat • Potentially slightly higher cost than GX but more available resource • Best heat pump option for this location • Some further optimization may be possible with cooling service to commercial loads • Natural gas cogeneration • BC Hydro is interested in systems which also produce electricity • Best commercial electricity production option at this scale. • Natural gas cogeneration is a stepping stone to biogas cogeneration • GHG emissions depend on whether we use provincial perspective or regional trade perspective.
Summary Results – Base Case No Grants, Private Financing, Property Taxes Included
Summary Results - Grant Requirements Grant required to achieve competitive rates and target return on investment. Municipal financing scenario assumes 100% debt financing and no property taxes.
Summary Results – Conclusions • All options require some level of grants to achieve competitiveness and break-even requirements. • Biomass is least cost option in all demand scenarios and has the highest total GHG emission reductions and greatest reliance on local resources. • All options exhibit economies of scale. Competitiveness increases as total system size increases. Securing a large service area is critical to success. • Under a municipal financing model and excluding property taxes, the larger biomass system starts to approach BAU costs, even before taking into account grants.
Possible Optimizations (Design Phase) • Solar DHW • Alternate siting of energy centre • Multiple energy centres • Distribution layout • Actual sizing and staging of capital items • Specific technology / vendor selection
Key Implementation Risks for District Energy • Securing loads • Marketing • Relationship building • Policy / bylaw support • Minimizing installed capital costs • Technology selection • Coordination with other infrastructure • Competitive tendering • Performance contracting • Phasing of equipment relative to loads • Just in time capital where possible • Build in flexibility • Optimize staging and siting • Ensuring optimal building performance • Developer design document • Design and commissioning support • Retrofit support
District Policy Role • Establishing target core service area boundaries • Cultivating community support • Developing measures to promote/require interconnection • Establishing commitment to interconnect municipal buildings • Creating mechanisms to support efficient planning/installation of linear infrastructure • Establishing policies and programs to encourage/facilitate access to energy resources • Facilitating the selection of site(s) for energy center(s) • Establishing policies for property taxes and franchise fees
