We review towards zero and zero carbon remote community energy systems using wind and solar electricity generation combined with battery and thermal energy storage systems. Systems are modelled in the context of the Xeni Gwet’in First Nation Community located in the Nemiah Valley in British Columbia, Canada. The community has a population of 200 residents, most of whom are connected to the local microgrid. The goal of this research was to (1) investigate how low-cost thermal energy storage impacts the levelized cost of energy of these systems, and (2) assess the sensitivity of unmet energy capacity of the system at varying storage costs. Electrical and thermal load profiles for the community were developed and determined to average a combined annual load of 2 GWh with a peak of 900 kW. A model of the proposed system was built in HOMER Pro® and sensitivity analysis of PV, wind, and hybridized energy storage costs was conducted. Results indicate that as wind and PV costs are projected to decrease, minimizing the levelized cost of energy of the energy system is less dependent on thermal energy storage cost.; this correlation decreases as unmet capacity increases. Moreover, the analysis suggests that these systems yield greater than 70% curtailment of solar and wind energy, regardless of energy storage costs.
