Pathways towards a defossilated sustainable power system for West Africa
within the time horizon of 2015–2050 is researched, by applying linear
optimisation modelling to determine the cost optimal generation mix to
meet the demand based on assumed costs and technologies in 5-year
intervals. Six scenarios were developed, which aimed at examining the
impact of various policy constraints such as cross-border electricity
trade and greenhouse gas emissions costs. Solar PV emerges as the prime
source of West Africa’s future power system, supplying about 81–85% of
the demand in the Best Policy Scenarios for 2050. The resulting
optimisation suggests that the costs of electricity could fall from 70
€/MWh in 2015 to 36 €/MWh in 2050 with interconnection, and to 41 €/MWh
without interconnection in the Best Policy Scenarios by 2050. Whereas,
the levelised cost of electricity without greenhouse emission costs in
the Current Policy Scenario is 70 €/MWh. Results of the optimisation
indicate that a fully renewables based power system is the least-cost,
least-GHG emitting and most job-rich option for West Africa. This study
is the first of its kind study for the West African power sector from a
long-term perspective.
