| Abstract | This study was performed to determine how to achieve energy efficiency in the urban
residential sector with a pilot demand-side management program for the electric system of
Laos (Vientiane). The demand-side option chosen is the use of efficient lighting appliances in
household sector. Residential lighting load shape is modeled based on customer behavior.
Electricity consumed by lighting contributed 21 % of total electricity use in the surveyed
households. About 60 % of total lighting load in this sector was traditional fluorescent lamps ,
while incandescents accounted for 40%. Therefore, using more efficient lighting technology
available was considered a major area where electricity as well as dollar could be saved.
The survey in the selected urban area of Laos was conducted for analysis of lighting
load shapes. The results showed that demand-side management options like use of both
efficient fluorescent lamp and ballast is the highest foreign currency gain and decreased the
system peak load by 4.28%. Most of the residential customers consume less than 200 kWh per
month of electricity. The low electricity tariff of that consumption level is not interesting from
customer's perspective. At a tariff of 25 kips I kWh , replacing one incandescent would result
in a present value savings of 4,354 over 5 years. These savings are probably not enough to
attract consumer participation at the current domestic tariff. The utility should purchase bulk
volume of efficient lighting appliances and make cost recovery through the Automatic Price
Mechanism.
Cost- benefit analysis was performed in order to depict the electricity savings and net
foreign currency gain that could be realized from exporting saved energy at the time -of-day
peak tariff of US 5.8 c I kWh. |
