Abstract:
The potential of energy saving by the implementation of a voluntary appliance energy
labeling program in Sri Lanka was studied by analyzing the appliance market and the
system load profiles. End use load profiles for 2006 were derived from the Load Research
findings and energy statistics published by Ceylon Electricity Board and Energy
Conservation Fund. Air-conditioners, Lighting, Motors, Refrigerators and Fans were
identified as potential end uses for energy labeling. The market distribution of efficiencies
and prices were gathered for the identified end uses and the existing market picture was
modeled. Average efficiency level of appliances in the present market was calculated.
Market transformation anticipated by implementation of a voluntary Energy Labelling
Program was established under a hypothesis consists of a set of assumptions bases on
incremental cost associated with the decision of purchasing a more efficient appliance,
pay back period of the additional investment, market penetration of labels, consumer
preference on making use of energy efficiency and other related factors. Anticipated
market pattern after the implementation of Energy Labelling was modeled based on the
market transformation and the average efficiency level of appliances in the transformed
market was estimated.
Overall improvement of the average efficiency for each identified appliance was estimated
and the energy and demand saving due to that was calculated. It was found that
implementation of an voluntary energy labeling program for above identified appliance
would result in an annual energy saving of 217.8 GWh and system peak demand reduction
of 47.6 MW. Over 9 million US$ and can be saved annually by the energy saving while
assuring 60 million US$ avoided capital investment due to the peak demand chipping by
47.6 MW.
