National Rational and Efficient Energy Use Programme (PRONUREE)
Policy measure

As part of the National Rational and Efficient Energy Use Programme (PRONUREE) with the objective to improve energy efficiency in the various sectors that consume electrical energy, a simple initiative was implemented in Argentina in 2007 to reduce energy demand. (ECLAC, 2010)


The initiative introduced distinguished summer-and winter-time, whereby the sun would rise and set one hour later than before. The effect of the change in time on electrical consumption was measured in spring 2008.

To evaluate the impact of the change on energy consumption and peak power demand, the average demand for the period (1 January through mid-March 2008) was compared with the consumption during that period of the preceding year, adjusting 2007 demand for representative average growth. The study examined demand on all electrical distributors in the various distribution regions, except for demand from the major users.

The effect on energy consumption and peak power demand was calculated, comparing real 2008 values with the corresponding 2007 values adjusted for average growth during the period. This approach provided a relatively simple way of evaluating the overall impact in each region, although more variables play a role in the levels measured. (ECLAC, 2010)

No identified challenges.

The change from GMT-3 to GMT-2 moved sunrise and sunset to a later hour, which led to changes in consumption as a result of lighting needs around sunrise and sunset. The total savings from all districts in average MW was 82 MW for the average savings and 432 MW for  peak energy savings.  (ECLAC, 2010)
