An analysis of the Ghanaian power generation sector using an optimization model
Abstract
The Ghana power sector has faced several challenges in the area of supply-demand balances alongside electricity tariffregulations, in particular during the past decade. This has had direct consequences on its ability to meet increasing demand.Other issues are expected to arise in the future, such as the introduction of carbon tax and a move to renewables to reduceatmospheric emissions. This paper addresses these issues through creating scenarios and making comparisons, whichprovide ideas on how these situations might affect the generation mix and the cost of generation. To this end a shortruncomputable model of the Ghana power generation system was developed to analyze those scenarios. The model isdeveloped in the General Algebraic Modelling System (GAMS) as a Linear Programming problem.References
