Demand Side Management of Household’s Lighting Considering Energy Use and Customer Preference: a Preliminary Study

Abstract— This paper presents electricity utilization and saving potential assessment for residential
lighting demand side management program. The assessment involves combined Baseline Energy Use
method and Analytic Hierarchy Process which represent technical and customer preference approaches,
respectively. Residential lighting load curve and lamps’ share of ownership are estimated based on the
first method whereas selected lamp energy saving strategy is obtained using Analytic Hierarchy Process.
The selected research area is on the residential sector of Surabaya, which is the second largest city in
Indonesia and involving 762,248 households represented by 384 households as survey participant. From
the analysis, the city’s annual electricity consumption from lamps utilization in residential sector is
estimated around 1,747 GWh. As two mostly selected saving strategies, simultaneously applying Peak
Clipping in terms of switching off selected existing lamp during peak hours and Energy Efficiency in
terms of existing lamps replacement with energy efficient ones would achieve annual electricity saving
around 476 GWh. Moreover, around 40.8 MW peak load reduction would be potentially reached or
around 7.7% reduction on Surabaya distribution system’s peak load.
