Renewable energy integration into community energy systems: A case study of new urban residential development

The objective of this study is to propose a systematic framework for renewable energy integration in community development. A scenario-based study was conducted for an upcoming neighbourhood in Okanagan, British Columbia (BC), Canada. Scenarios were assessed based on the life cycle cost (LCC) and GHG emission reduction. The scenarios were then compared based on costs and benefits to key stakeholders. Results of this study revealed that a higher share of renewable sources in the energy mix does not necessarily reduce LCC or GHG emissions. The benefits which can be achieved via incorporating renewables to the regional energy mix varies, depending on the existing energy sources in the mix. Therefore, regional power grid mix influences the feasibility and acceptability of RE integration at a given location. Developers should be aware of the optimal investment level which could be fully or partially recovered by premium home prices. The government should promote this practice via various incentives such as tax credits, grants etc. Findings of this research would mainly inform urban developers in renewable energy planning and local government in formulating climate action policies.
