This paper used the Slack-based efficiency data envelopment analysis model (DEA) to assess the efficiency of electrical distribution regions (EDRs) in Ghana, using Electricity Company of Ghana as a case study, an analysis that had not been previously conducted on the ECG. Results showed that the efficiency dipped drastically in 2013, but improved from 2014 to 2016, stagnating in 2017 and dropping further in 2018. The consistency of the estimations was ensured by establishing the production frontier's form, variable returns to scale.
