Hydro-Solar systems have the hydro and the solar power technologies working together in synchronized mode. These systems are designed to take full advantage of the abundant renewable energy resources available all year round. In the Nigerian environment, the solar component of the hybrid plant works at peak during the dry seasons while the hydro component of the plant works at peak during the wet/rainy season.
Hybrid Engine & Solar plants have gas engines and solar power plants working in synchronized mode. The aim of the solution is to provide appreciable fuel cost savings during the sunny periods of the day. The solar systems are designed to bear most of the load during the sunny periods while the engines are placed on standby to gradually take on the electric load as the sunlight intensity reduces and vice versa.
