Prezado(a) Senhor(a), Em continuidade ao processo de divulga\u00e7\u00e3o de informa\u00e7\u00f5es a respeito da opera\u00e7\u00e3o dos reservat\u00f3rios da Bacia do Rio S\u00e3o Francisco, conforme tratativas entre Eletrobras Chesf e o Operador Nacional do Sistema El\u00e9trico \u2013 ONS, comunicadas na 1\u00aa Reuni\u00e3o de Acompanhamento das Condi\u00e7\u00f5es de Opera\u00e7\u00e3o do Sistema H\u00eddrico do Rio S\u00e3o Francisco, ocorrida na data 10\/01\/2023, daremos continuidade ao processo de eleva\u00e7\u00e3o gradual das deflu\u00eancias para os reservat\u00f3rios de Sobradinho e Xing\u00f3. Desta forma, objetivando seguir as curvas de volume de espera, apresentamos a programa\u00e7\u00e3o da citada eleva\u00e7\u00e3o para os reservat\u00f3rios de Sobradinho e Xing\u00f3 para o patamar de 4.000 m\u00b3\/s, a partir de 13\/01\/2023, sexta-feira, devendo permanecer no citado patamar at\u00e9 nova reavalia\u00e7\u00e3o:<\/p>\n

Destacamos que os valores acima indicados correspondem \u00e0 deflu\u00eancia total, podendo ser turbinada e\/ou vertida, a depender da necessidade de atendimento ao Sistema Interligado Nacional \u2013 SIN, conforme procedimento de otimiza\u00e7\u00e3o energ\u00e9tica envolvendo as diversas regi\u00f5es do Pa\u00eds, coordenado pelo ONS.<\/p>\n

Destacamos ainda que a situa\u00e7\u00e3o hidrol\u00f3gica est\u00e1 sendo permanentemente avaliada, podendo haver altera\u00e7\u00f5es nestes valores em fun\u00e7\u00e3o da evolu\u00e7\u00e3o das chuvas e vaz\u00f5es na Bacia do Rio S\u00e3o Francisco.<\/p>\n

Caso as altera\u00e7\u00f5es na programa\u00e7\u00e3o de deflu\u00eancias se configurem, ser\u00e3o previamente comunicadas, com o horizonte que as ferramentas dispon\u00edveis possibilitam.<\/p>\n

Ressalta-se que a vaz\u00e3o m\u00e1xima de 4.000 m\u00b3\/s n\u00e3o deve extrapolar a calha principal do Rio S\u00e3o Francisco e corresponde \u00e0 metade do valor da descarga de restri\u00e7\u00e3o no trecho de Sobradinho at\u00e9 a Foz, qual seja 8.000 m\u00b3\/s.<\/p>\n

A opera\u00e7\u00e3o que est\u00e1 sendo realizada segue os padr\u00f5es estabelecidos pelas regras, diretrizes e restri\u00e7\u00f5es vigentes, em especial, para o controle de cheias.<\/p>\n

Carta Circular-SOO-004\/2023, de 10\/01\/2022 – 2\/2 Classifica\u00e7\u00e3o do documento:<\/p>\n

P\u00fablico \u00c9 fundamental chamar aten\u00e7\u00e3o para a import\u00e2ncia da n\u00e3o ocupa\u00e7\u00e3o de \u00e1reas ribeirinhas situadas na calha principal do rio, haja vista o per\u00edodo \u00famido em curso e a possibilidade de eleva\u00e7\u00e3o das vaz\u00f5es para valores acima de 4.000 m\u00b3\/s, a depender da evolu\u00e7\u00e3o do quadro de chuvas na Bacia.<\/p>\n

Informamos que as altera\u00e7\u00f5es de vaz\u00e3o ser\u00e3o comunicadas tamb\u00e9m atrav\u00e9s de mensagem SMS.<\/p>\n

Solicitamos a V.Sa. a ampla divulga\u00e7\u00e3o junto \u00e0s comunidades ribeirinhas.<\/p>\n
