Techno-economic opportunities for integration of renewable energy into the Saskatchewan energy system using EnergyPLAN

Many renewable energy opportunities exist but scientific gaps remain on the techno-economic feasibility of a transition, especially when systems are considered holistically across all energy sectors. The purpose of this study is to investigate the efficacy of Smart Energy Systems using renewable energy compared to carbon capture and storage technologies. These decarbonization strategies are investigated through a case study in Saskatchewan, Canada. The study uses EnergyPLAN for modelling the energy system and considers the transportation, heating, industrial and electrical sectors. The analysis demonstrates that a Smart Energy System and renewable energy is feasible and preferred based on energy system efficiency, carbon dioxide emissions and costs. A transition has been shown to reduce annual carbon dioxide emissions by 52 % and total annualized system costs by 20 % with further reductions achieved by increasing the capacity for interprovincial trading. • A Smart Energy System in Saskatchewan would make contributions to decarbonization. • The existing Saskatchewan energy system can integrate additional renewable energy. • Interprovincial cooperation can further optimise the energy system. • A reduction in grid stabilizing units enhances renewable energy supply. • A Smart Energy System can reduce CO 2 emissions by 52 % and system costs by 20 %.
