Abstract
From the cost models, full cost of diesel electricity generation including the bulk fuel purchase, delivery, and electricity generation at the three sites varied depending on the annual electricity demand; $0.66/kWh at 3300 MWh, $0.89/kWh at 1500 MWh, and $1.46/kWh at 1400 MWh, respectively. These costs compared well with actual customer rates at the two larger sites. Switching to methanol resulted in an increase of $0.046/kWh, $0.085/kWh, and $0.066/kWh, and dimethyl ether saw in an increase of $0.04/kWh, $0.11/kWh and $0.044/kWh, respectively, in the full cost of electricity. New bulk fuel storage projects increase the cost of electricity further between $0.05/kWh and $0.10/kWh. However, a $30/tonne CO2 penalty adds $0.08/kWh for diesel electricity generation, whereas bio-based methanol and DME would be exempt. In light of the potential socioeconomic benefits from switching to clean biofuels, as well as avoiding the enormous costs associated with the clean-up and economic losses due to a marine oil disaster, these clean fuel options seem reasonable as “transition technologies” toward renewable energy to replace diesel electricity generation in Canada's most remote northern communities.
