This study evaluates the impact of energy outages and in-house power generators on capacity utilization among approximately 12,000 African firms. Energy outages and in-house power generators are measured by the days that firm experienced energy outages and the share of self-generated electricity as a proportion of total electricity consumed, respectively. We further construct quantile dummies based on outage days and the self-generated electricity share. The estimation results depend on the measurement of these key variables and whether the joint impact of energy outages and in-house power generators is accounted for. For example, only in the model that include outage days, the self-generated electricity share, and the interaction term between them, both outage days and the joint impact are found to be significant. This study provides a comprehensive assessment of the effects of power outages and generator ownership on capacity utilization, offering valuable managerial and policy insights.

能源中断、内部发电机和产能利用率：非洲制造业的案例

本研究评估了大约 12,000 家非洲公司的能源中断和内部发电机对产能利用率的影响。能源中断和内部发电厂分别通过公司经历能源中断的天数和自发电占总消耗电力的比例来衡量。我们根据停电天数和自发电份额进一步构建分位数虚拟人。估算结果取决于这些关键变量的测量，以及是否考虑了能源中断和内部发电机的共同影响。例如，只有在包含停电天数、自发电份额以及它们之间的交互项的模型中，才发现停电天数和联合影响都很重要。本研究全面评估了停电和发电机所有权对容量利用率的影响，提供了有价值的管理和政策见解。
