Electricity in most developing countries is inefficient, erratic and unreliable. Recent research work on grid-connected hybrid system in developing countries have not considered frequent electricity outage hours per month experienced by consumers. Effort is made to address this critical factor and HOMER software was used to model an intermittent power grid integrated with a hybrid energy system. This shortcoming is addressed by assuming generator component in HOMER to run as grid. This is made possible after some modification to fuel content, minimum load capacity ratio and scheduling capacity of the generator. A city in Nigeria was used to demonstrate this approach, but it can be replicated for any location in developing countries where there is frequent electricity outage. Outcome of the model shows that integrating an intermittent power grid with a hybrid energy system offers a competitive cost of energy, reduction in noise pollution and improved use of renewable energy for electricity generation in developing countries.
