BASELINE ENERGY USE BASED RESIDENTIAL LIGHTING LOAD CURVE ESTIMATION: A CASE OF SURABAYA

Residential lighting is one of important appliances that, in total, consume large amount of electricity. Establishment of
residential lighting load curve is therefore prominent as the curve will be useful for any further analysis. Nevertheless, it
is difficult to develop residential lighting load curve when the residential energy consumption is measured using
conventional metering or other power monitoring device. This paper presents estimation of residential lighting load
curve using Baseline Energy Use method. A survey has been conducted to collect relevant data of lighting utilization in
Surabaya. Important findings from the survey include determination of number of each lamp type, average number of
lamps per household, total number of lamps in households, and average daily operating hours. Considering a 96.2
share of ownership which consist of incandescent, fluorescent, and compact fluorescent lamp, it is found from the
analysis that the lighting peak load is occured at 7 PM with average wattage per household of 100.1 W. Meanwhile,
residential sector’s lighting peak load is reached 76.3 MW. In addition, no coincidence found when the lighting load
curve compared to the adjusted system loading curve.
