Background of Study• There’s a big gap between electrification rate in urban and that in rural area inCambodia• Two main targets in terms of energy access• By 2020, all the villages are electrified• By 2030, 70% of households are connected to grid-quality network• What is the most suitable solution for the unconnected households?

JASTIP Phase 1 in Cambodia (WP2)
1. 2017 Starting QOL (Quality of Life) survey in Kampong Cham Province andKampong Speu Province under the JASTIP WP2 activity (Rural Electrificationstudy).
• The objective is to study on the impacts in villagers’ lifestyle and economic condition“before and after” their electrification by different RE implementation schemes andregion, countries.
è Develop suitable hardware and software for rural community and policy assessment
2. 2018 “Innovative DC grid for improving the quality of life of rural area inCambodia” (JASTIP-net)• The objective is to introduce an innovative dc grid taking energy from an associationof solar home systems for supplying to a small number of households.
3. 2019 “Deployment of a low-cost device for estimating energy production from aPV system in faulty conditions for a remote rural health care center” (JASTIP-net)• The objective is to design a tool which enable the prediction of energy production
from a PV system in both normal and abnormal operating conditions.

Survey Questionnaire
Wisconsin QoL indicators (M.A. Becker,
2014)• General satisfaction level• Economic well-being• Psychological well being• Physical well-being• Social well-being• Occupation

Energy consumption• Electricity appliances• Time of use• Duration of use• Cooking method
External conditions• Transportation• Schools• Hospitals

Examples of Survey’s results

Summary of Key Findings and Recommendations
Key Findings• Electrification did not translate directly into a substantial increase in income or workingtime• The installed capacity plays a very important role in the improvement of QoL• There’s no significant difference in terms of electrification whether the power source isfrom grid-extension or stand-alone• A period of time is generally required for the villagers to adapt and discover the potentialof electricity to improve their QoL further

Key Recommendations• A more focus on electrifying income-generation activities• Electricity serving community service should be prioritized such as health center, school,
agricultural activities, clean water• Innovative business model should be introduced in order to accelerate the electricity
access rate of households in rural areas• Further analysis on the sustainability of the system needs to be performed whenselecting the electrification scheme (stand-alone or grid extension or hybrid)• Further investigation for a longer-term observation and wider geographical area

Benefits and Expectation of the Project
Benefits of the project• Though the budget is limited, the project paved the way for new research possibility anda wider research network among ASEAN• QOL study is an example of multidisciplinary research, electrical engineering and social
science. Many students have been involved in this study.
• The subject is very much relevant to the country’s context. Hope it can contributes to thechoice decision of technological solutions to local society

Expectation from the projects in JASTIP Phase 2••••More experience sharing among ASEAN countries who have similar conditions
Research students mobility among ASEAN countries
Join supervision of research students
Co-production of scientific material
