INGENIEUR Malaysian Rural School Electrification Programme using Solar PV-Diesel Hybrid System By Dr Abdul Muhaimin Mahmud Electrical Engineering Branch, Public Works Department Alternative energy technology has been used widely in Rural Electrification Programmes (REPs) all over the world for many years. Renewable energy sources, such as solar, wind and biomass, are the preferred choices given the abundant resources available on site and the sophistication of the technologies involved. Combinations of two or more of the resources, together with an energy storage system and occasionally a conventional energy generator, create a hybrid system, which is reliable and durable. In Malaysia, solar photovoltaic (PV) based systems, implemented on a large scale, can provide round-the-clock electricity services for areas that are inaccessible by the electricity grid network. One of Malaysia’s REP initiatives is a solar PV-diesel hybrid system for 160 schools in rural Sabah. This article provides an overview of the programme, challenges in implementing the initiatives and how it benefits the educational environment in rural areas. R enewable energy technology has long been used as an alternative stand-alone electricity power supply for rural and remote areas that are not connected to an electricity grid network. More than 1.4 billion people still live in areas without electricity, mostly in South Asia and Sub-Saharan Africa [1]. Meanwhile, almost 1.2 billion will still be without electricity by 2030 [2]. It is unlikely that an area without electricity can be developed economically, as it is an important factor in modernisation. In rural areas, 6 50 VOL - SEPTEMBER 2017 VOL 71 55 JULY JUNE 2013 geographical conditions, the smallness of village sizes and the remoteness of the locations mean that the extension of an electricity grid network is considered to be expensive, uneconomical and not attractive as an investment, either by the Government or the private sector. Rural Electrification Programmes (REP) encompass the process, plans, programmes and initiatives overseen by the Government, the private sector, and institutions or organisations in the name of fighting poverty, enhancing economic growth and balancing out the development between urban and rural areas. People and communities can embrace modern civilisation if electricity is made available because it can benefit their lifestyle by improving health, education, the economy and technology [3]. Renewable energy sources, such as solar, wind and biomass, are the preferred choices given the abundant resources available on site and the sophistication of the technologies involved. Combinations of two or more of the resources, together with an energy storage system and occasionally a conventional energy generator, create a hybrid system, which is reliable and durable. Among all the renewable energy technologies that are available, the solar PV system is a popular option in off-grid rural areas [4]. In Malaysia, solar photovoltaic (PV) based systems, implemented on a large scale, can provide round-the-clock electricity services for areas that are inaccessible by the electricity grid network. One of Malaysia’s REP initiatives was a
