THAILAND is now facing energy crisis in both short-term and long-term, which can be seen by deficient of fossil fuel situation such as oil, coal, and gas. The energy prices gaming around the world leads to higher price and unpredictable fossil fuel prices in last 5 years (2003 - 2008). Moreover, Thailand has very low national fossil fuel resources and mainly relies on imported fossil fuel. In the electricity generation sector, natural gas, lignite, hydro power, and heavy fuel oil, share approximately 70%, 13%, 5% and 5%, respectively [1]. Alternative energy, such as biomass, wind, garbage, and solar powers are only 2% of total electricity generation and comparatively low to those countries in European Union. As a result, the Ministry of Energy has developed the Alternative Energy Development Policy and Planning for 15 years (2008-2022) with the target of increasing in alternative energy to 20% of overall energy consumption in Thailand by 2022, with 42 M ton of GHG [2]. Ministry of Energy, therefore, issues the energy compulsories in several ways as follows; 1. Enhance public participation in development of alternative energy utilizations. 2. Enlarge Clean Development Mechanism (CDM) by alternative energy used. 3. Expand green city concept and increase the alternative energy through community participation. 4. Develop technology and knowledge transfer mechanism for alternative energy used to community that diminishes the risk in alternative energy investment. According to the potential of micro hydro in Thailand, the micro hydro power plant is feasible to build and operate for rural area [3-4]. However, the appropriate designed micro hydro for rural electrification is needed to develop base on low cost system, acceptable efficiency, local materials using and do it yourself. This research presents the study to investigate the possibility of the stand-alone micro hydro for low-cost electricity production which can satisfy the energy
