The heavy rain that has reached the South and the improvement of the status of the region practically withdrew tanks risks of energy shortages in the Southeast. The capacity of the reservoirs in the region reached 2.5% this month. The chairman of the Energy Research Company (EPE), Mauricio Tolmasquin recalled in an interview with Brazil Agency, in June 2001, when rationing, the risk was 29.6%.
"The South has received heavy rain since early June, giving relief to the reservoirs in the region, after an unusual dry period during the summer. So we have to enjoy the rain in the South there to transfer the energy generated to Southeast, "said Tolmasquin. He said the Executive Summary of Monthly Operation Program, released by the National System Operator (ONS), for the period from 14 to 20 June, which significantly increased the estimates of rainfall for the South, improving the situation of the reservoirs this month .
The president of the SPC, there is no doubt that the hydrological conditions in the South have greatly improved the situation of the country in terms of the electricity supply. "It was important improvement. Today, we are in a state of tranquility. If longer before we considered that there was no supply problem, today we already sure you will not lack energy. The level of deficit is quite low, "he said.
Tolmasquin reminded that the country has in the beginning of the year, especially in February, the worst period in its history in terms of hydrology, much worse even than in 2001, the year of rationing. "In February 2001, the natural energy flowing, ie the flow of water that entered the reservoirs was 73% of the long-term average. Last February, this flow was only 39% of average - almost half of the water that entered in 2001, "he said.
According to him, however, despite having half the flow entered earlier this year, in late February reservoirs were nearly identical:. 35.1% in 2001 from 35.4% in 2014 "The difference today is the result of being structurally better than in 2001 ". The president explained that the SPC was precisely this "best soundness" of the National Integrated System has enabled the country through the time of shortages and the crisis arising from atypical drought. Tolmasquin also noted that between 1996 and 2000, the installed capacity grew by 24.6%, against a consumption increase of 26.5%.

ONS predicts more rain for South with index above average "At that time, consumption grew more than the installed capacity. Between 2001 and 2013, the installed capacity increased 72.4%, while consumption grew by only 50.8%.
Citing recent figures, the president of the company responsible for energy planning highlighted the diversification of the Brazilian energy matrix as fundamental to overcome the problems of lack of rain and significant drop in the reservoirs.
"In 2001, hydropower accounted for 82% of the generation capacity of existing energy while now, in early 2014, accounted for 65%. Moreover, the number of thermal capacity and power supply for them, which increased from 16% to 29% of the matrix. Not to mention the wind [from the wind], the park now accounts for 2% of the generation capacity. "
According to the president of the SPC, was also essential for overcoming the difficulties increasing the number of transmission lines. Between 1996 and 2002, were installed on average in the country, 1562 kilometers (km) of lines per year. Between 2003 and 2013, that figure more than doubled, increasing on average for 3710 km of lines annually. "And it has increased enormously exchange between regions."
To Tolmasquin in 2001 was no water left, but there was no energy transfer to the Southeast, "because the exchange capacity of the South to the region was only 2,600 megawatts (MW) and today is 5,800 MW.
The president of EPE admitted that with falling prices in the spot market (instant, immediate), the government could already start off some heat, but for the sake of safety, are opting to keep them connected to replenish the reservoirs and not be surprised. "Now, of course, persisting data, at some point it will be evaluated," and then begin to turn off the heat. We're still evaluating. "
Tolmasquin admitted that thermal and gas reservoirs in the North and South regions helped sustain the demand for energy in the worst moments. "The North and the South is that helped hold. And that's the beauty of our interconnected system - which is unique in the world. In a continental country, with distinctive hydrology and climate, there is a cooperative system in which a region better off can help each other. "
