A hybrid power system uses a combination of renewables and reciprocating generators to generate electricity. The usage of renewables can significantly reduce the consumption of fuel and the amount of CO2 emissions released into the atmosphere.
The Republic of Kiribati, a small Pacific island, successfully uses a hybrid power system to reduce their diesel requirements by 227,000 litres per year. Their system also prevents around 627 tons of CO2 from being released into the atmosphere.
As with most Pacific islands, they originally used diesel generators to generate 100% of its electricity. But, in order to reduce the dependency on diesel imports a 500 kWp photovoltaic power plant was built and integrated into the Public Utilities Board’s electrical grid.
ComAp’s engineers then installed a hybrid control system to ensure a consistent level of power is generated between the two sources. So when the sun goes down the diesel generators pick up the slack and the lights stay on.
