ABSTRACT: 1) The paper examines the relationship between electricity demand
and climate/non-climate related factors using statistical regression analysis. 2)
It focuses on the environmental, demographic, policy (energy pricing) and
technological factors as the main factors affecting the consumption pattern in Jordan. 3)
The paper also presents the variations occurred in the electricity demand over
the period 1994-2008. The variations that are observed during the period of
study are: Shifting of the peak load occurrence from evening to morning period,
Modification in the annual daily load curve especially in winter season,
Variation in relationship between space temperature and demand especially in
winter, and dramatic increase in electric generation after year 2003. The shift
in peak load from evening to morning period is mainly due to technological
factor as a result of wide use of the air conditions in houses, services and
government offices for cooling in summer instead of ordinary air fans. The
variations in consumption pattern between 2000 and 2007 are mainly associated
with economic, social and demographic factors. The high demand at lower space
temperature is governed by introducing new appliances for heating in winter as
a result of low electricity pricing comparing with gasoline price. The dramatic
increase in electric generation after 2003 is probably due to demographic
factors as a result of high growth of population after the Gulf war II. 4) The
correlation between the daily maximum loads in morning and evening periods with
the differential temperature (ΔT) above 20?C threshold in summer and below 15?C
threshold in winter, shows pronounced changes in 2007 compared with year 2000.
The regression tests show that a decrease of 1?C below 15?C threshold in winter
1) increases the morning demand by only 2 MW/?C in 2000 and 16.7 MW/?C in 2007,
2) decreases the evening peak by ?2.6 MW/1?C in 2000 and increases the evening
peak by 22.9 MW/1?C in 2007. Results show that the demographic, technological,
environmental and national energy pricing factors play a vital rule in consumption
pattern in Jordan. Moreover, the paper reveals that planners and decision
makers should be careful when applying new tariff in the developing countries
such as Jordan.
