Feasibility Study of Renewable Energy Supply for Out door Campus University Surabaya, Trawas, Indonesia

This paper describe a feasibility study of different renewable energy supply systems for the Ubaya Training Center (UTC) in Indonesia.Various combinations of renewable energy sources and electrical loads have been compared in order to find the best financially viable solution.The potential of wind, hydro and solar energy has been assessed as possible sources of energy. None of the assessed system combinations reached payback within the assumed lifetime of 30 years.A solar powered, grid connected partial power supply for the UTC building complex and an off grid solar powered water pumping system show almost idential financial performance curves and also show best financial viability.
