Abstract: 

One of the policies for managing the spread of demand for electric energy during the day is use of Daylight Savings Time (DST). To reduce energy consumption and the peak load, the Iranian government moves the official clock forward one hour in the first month of each year and moves it back in the 7th month of the year. In 2006 the Government decided not to change the official clock.
Incidentally the country experienced five times more blackouts in that year compared to the previous year. In this paper we apply Panel Data Analysis to the 16 electric companies operating in Iran to study the impact of DST on the total electricity consumption. We used an Iterated Seemingly Unrelated Regressions (ISUR) technique to estimate energy demand for the first six months of the years 2005 to 2008. The results of this investigation show that DST by shifting electricity use in evening hours to midnight and daybreak reduces the peak load and achieves a more even use of electric energy. However, our findings show that implementation DST increases the total electricity demand in Iran.
