Abstract

Following the f^aster plan on electric power development in Vietnam No. ViPl Vietnam will face the lack of

energy resourses for generation electricity by 2015. However, nee husk in the central of Mekong Deila

Region has not been used efficiently The purpose of this paper is to find an optimal plan of using nee husk

as a fuel for energy development through a general planning model.

The results show that, if using redundant nee husk for generation electricity and steam which is used la

factory m industrial zones (IZs), it meets 7.1% of total electric demand of the city, and total stream demanS

of Tra Woe and Thot Not IZ. These results prove that using effectiveily rice husk as fuel will bring a fiigli

economic efficiency.

1. Introduction

According to the Master plan of energy No,

VU (2011) of the EVN, the energy demand for is 80.9

million TOE m 2020, 103.1 million TOE m 2025. It

is remarkable that Viemam will lack power sources

firom 2015 [1]. As the energy demand increases, the

cost, energy security and environmental issues

become urgent, which affect directly the sustainable

development of the domeshc economy.

In the recent 30 years ago, the world is

looking for alternative clean energy sources rather

than fossil fuels which are becoming exhausted and

causing environmental pollution In Vietnam, a

country of agriculture, there is a large potential

source of biomass. In particular, Vietnam is the

second largest rice exporter in the world, it is

estimated that the annual emission of rice husk from

milling factories is about 7.5 million tons, but only 3

million tons are used, of which 50% is concentrated

in the Mekong Delta [2]. Furthermore, the use of rice

husk as fuel to generate electricity and steam has

been proven to be cost competitive with fossil fuels

[3]. The problem of redundant husk sources is

onginated from the lack of efficient strategy of the

planning of rice husk for each region and sector.

The objective of the paper is, through the

planning model, to find the optunal plan of using rice

husk fuel sources for energy development in general,

and to apply lo center of South-Western Region -

Can Tho city.

Parameters studied are generation capacity

and the rate of energy/steam generation of energy

plants. Research methods include data statistics and

analysis (nee husk and energy needs in the past and

prediction of the future). Based on the linear planning

model with regards to the minimum transportation

cost of husk to select locations, capacities and

generation rate of the power plant.
