Abstract

This paper focuses on evaluation of micro hydropower plant (MHPP) that applies overall equipment effectiveness (OEE) method. MHPP are used on the rural electrification and does not necessarily supply electricity to the PLN grid. They are utilized in isolated and off-grid systems for decentralized electrification. Some identified issues or problems are the results of insufficient site assessment, poor quality of power plant facilities and electro-mechanical equipment, controller equipment and inadequate operation and maintenance. To determine performance of MHPP is done the evaluation using OEE method especially some of the MHP in districts South Solok. The first step is observing the real condition of MHPP to find technical or non technical of primary and secondary data. The data are classified according to wich needed by OEE method. It has three main components such as availability, performance and quality. There are seven MHP as the research object. The results are obtained an availability average i.e. 68%, performance average i.e. 52% and quality average 67%. These achievements shown the MHPP production only reached a value of OEE i.e. 38%. Therefore, the production in the standard of the Japan Institute of Plant Maintenance (JIPM) is a bad class. The strong issues or problems of MHPP that found are management 17,2%, control systems 7,3%, turbine 10,6%, generator 32,7% and transmission 31,9%. Management includes costumer payment, skill of the operator and maintenance. Generators are major contributors to the problem because there are many MHPP does not have automatic control equipment.
