This paper investigated the impact of electricity service quality on the performance of manufacturing companies in Nigeria. Members of the Manufacturers Association of Nigeria (MAN) are the target participants. Data was collected using questionnaire survey from managers, owner-managers and the CEOs of manufacturing companies. Out of 600 distributed questionnaires, 319 were returned and 313 were found useful for analysis. The data was analyzed using PLS-SEM and the result shows positive effect for all the exogenous latent variables (electricity service quality) on endogenous latent variable (organizational performance) with exception of one factor (tangibility). This study contributes to literature on the use of service quality dimensions on electricity service. It also serves as guides for policy makers to pursue policies that enhance electricity service. The research limits itself to manufacturing firms that depend on service companies for electricity supply.
