With the end of daylight saving time at midnight on Saturday ( 15 ) , when clocks will be delayed by one hour in the states of South , Southeast and Midwest regions , the country will have saved £ 405 million in 120 days the validity of the measure , first instituted in the summer of 1931/1932 .

DST ends on Sunday
The measure took effect on 20 October last year and led to a reduction of approximately 4.1% of the energy demand from end of the two systems . This percentage, 4.3% was saved in Subsystem South , and 4.1 % in the Southeast / Midwest .
Data on the behavior of the National Interconnected System ( SIN ) , the duration of daylight , were released this afternoon ( 14 ) by the National System Operator ( ONS ) and point to a reduction in demand for electricity the peak time of the order of 2,565 megawatts ( MW ) , with 1,915 MW in Subsystem Southeast / Midwest and 650 MW in South Subsystem
The National System Operator reported that in the case of subsystem Southeast / Midwest , the reduction amounts to approximately 50 % of the load at peak hours in the city of Rio de Janeiro ( 6.4 million inhabitants ) , or twice the load at peak hours of Brasilia ( 2.6 million inhabitants ) . In the South, representing 75 % of the load at peak hours of Curitiba ( 1.8 million inhabitants ) .
ONS , however , the main benefit of daylight " was increased operational safety due to reduced shipments in the transmission network , which provided greater operational flexibility to perform maintenance on equipment ."
Of the total U.S. $ 405 million savings , gains related to the avoided cost with thermal generation to preserve the safety standards of the system resulted in economic benefits of U.S. $ 125 million , with only the reduction of thermal generation in the period outubro/2013 the fevereiro/2014 .
Additional $ 280 million related to the cost savings were avoided by reducing the value of the expected load to the tip of the National Interconnected System of 2,565 MW , which would have to have been met by thermal generation.
The figures also show that reducing average power of 295 MW represents 0.5 % of the load of the subsystems involved , of which 220 MW correspond to subsystem Southeast / Midwest and South Subsystem 75 MW , equivalent to 8 % of monthly consumption of the city of Rio de Janeiro and 14 % of the monthly consumption of Curitiba , respectively.
