The survival of any organization in a highly competitive environment depends on its ability to provide the best service quality to its existing customers as the quality of service is a key factor in the success of any organization. Though a stable supply of enough energy is a must for industrialization, Ethiopia’s growing industrial sector has come with an unprecedented rise in power demand. Despite the introduction of quality improvement programs and several customer care packages in the past, service quality gaps are still enduring in EEPCo.The study has the objective of assessing industrial customers’ satisfaction on service quality using SERVQUAL model. It also addresses the problems of quality gaps through the survey done at EEPCo, South Addis Ababa Region Industrial customers. The study was conducted using a descriptive survey method where the respondents were industrial customers and frontline managers. The sample size was 333 industrial customers and these were selected using simple random sampling technique. Front line managers were selected through purposive sampling. Moreover, structured questionnaires and interviews are tools used to gather relevant information and statistical tools like percentage, tables and charts are used to analyze the data. The study shows performance of EEPCo in providing quality service to its industrial customers is not in a situation to meet their expectations. In all dimensions of the SERVQUAL; tangibles, reliability, responsiveness, empathy, and assurance, it’s found that there is a negative gap between service expectations and service perceptions.Therefore, the Corporation should come up with an appropriate service delivery standards, proper complaint handling mechanisms, relevant training for its employees, and strengthening decision making power of employees.
