INTRODUCTION AND SCOPE OF WORK 1.1. Objectives of the Project The development objectives of the proposed Rural Energy II Project are to assist the Govemment of Vietnam to alleviate poverty in the rural areas by providing basic infrastructure service such as electricity and access to general services, for improving living conditions and productivity. The Project will assist the Government of Vietnam to implement I its national objective of providing electricity to about 12 million rural households through: - An effective strategy for rural electrification with special focus on provision of energy to the remote mountainous areas; I - Rehabilitating, upgrading and expanding the rural power system in order to meet the demand for power supply for future socio-economic development; - Strengthening reliability and quality of power networks, reduce voltage and electricity losses on the grid, lower rural consumption price, improve businesses efficiency and rural power management ability of local power management boards; 3 - Refurbishment of the existing rural power network to increase reliability and quality of supply, including reduction of technical and non-technical losses; this Project incorporates 19 communes in 6 districts (Muong Khuong, Van Ban, Si Ma Cai, Sa I Pa, Bat Xat and Bac Ha) of Lao Cai province. - Extension of existing power networks to supply additional households; - Assisting local District and Commune committees to improve power system I management processes and improve business efficiency, to provide electricity reliably, safely and at reasonably cost; - Review rural power management models, to establish power management units of legal standing, with economic independence and the managerial/technical skills to operate effectively and profitably, repaying loaned funds; I - Expanding the use of renewable energy for the off-grid systems to serve the rural load inthe remote and isolated areas, where feasible and economically practicable; 1.2. NEED FOR PROJECT INVESTMENT I Based on the forecast data on economic development, power demand, the current situation of the existing power distribution network of the Project's commune. The existing distribution network is degraded, not synchronous. Power losses are very high. The alignmeunt of power lines is not well designed. Many types of poles are existed in the network. The alignment of power lines is not well designed. There are also many types of X electricity meters. In the past in order to save money, the distribution lies were created to go across gardens, ponds etc. The conductor is overhead type and not covered by any insulating materials, so it cause a lot of risk on safety to local people. The Project is planned to implemented in order to: - Improve the quality of the existing distribution network in the Project's communes. l - Increase the safety management of the distribution network; - Reduce power losses; 2 I - Increase electricity supply for the Project's communes; l - Change the form for management model of rural power network; - Gradually modernize the distribution power network. * 1.2. Commune selection criteria 1.2.1. General criteria * To be voluntary participants in the Project and understand requirements and regulations of World Bank and the Government of Vietnam to carry out RE II I Project; * To be willing to convert the communes power management model to legal local distribution units to control LV networks; * To have potential for economic development; * To have an acceptable capital recovery rate; * Revenue from power business can cover management, operation and funding costs. 1 1.2.2. Criteria for selection of communes for rehabilitation * Power losses exceeds 20%; aged power networks degraded and require 3 refurbishment; * Power demand is substantial (over 500 households); * Power demand for industrial production is substantial (over 20%); 1 * Number of electrified communes over 80%; * Average power consumption rate power household in substantial; estimated 3 annually 500 kWh/household. 1.2.3. Criteria for communes to be connected 3 * Number of households connected to power network is Provincial communes is bellow the average (60%); * Customers are able to pay cost of connection and subsequent power bills; I * Communes have potential for development in agriculture, forestry and handicraft, which would be enhanced if electrified; * * Communes in the poorest communes list; * Communes in the assistance program of World Bank. l * Communes are ready to adopt the management model of power network.
