    ANDE can now interconnect the three hydroelectric power plants

    December 8, 2022 - CE Noticias Financieras


      Yesterday, the National Electricity Administration's (Eccande) Contingency Control Scheme, which will allow the safe integration of the National Interconnected System with the hydroelectric power plants of Itaipu, Acaray and Yacyretá, was put into operation.

      It was held in the central control room of the ANDE system, in the presence of the President of the Republic, Mario Abdo Benítez, who was accompanied by the Paraguayan general director of Itaipú, Manuel María Cáceres, and the head of ANDE, Félix Sosa.

      According to the authorities, the implementation of the contingency control scheme in ANDE is important to give greater reliability to the Paraguayan electricity system and, above all, to the users, said the head of the state-owned electricity company. "It is a historic day for the Paraguayan electricity sector, the result of the joint and coordinated work between ANDE, Itaipu and Yacyretá, aiming at a better service for the national market and regional electricity integration", Sosa emphasized.

      He also assured that the Paraguayan electricity system is now integrated and recalled that last year 34 cuts had to be made in the system for the transfer of electricity load from one hydroelectric power plant to another, which, as of today, will no longer be repeated after the commissioning of Eccande.

      Likewise, the head of ANDE stated that the Paraguayan power system is currently able to withstand the maximum consumption peak and highlighted the optimization of generation in hydroelectric power plants, where, in case of surplus, load transfers can be carried out automatically.

      Sosa also referred that -despite the efforts- there could be some inconveniences at the electric power distribution level; however, they would be minimal compared to other years. "It is in that area where we are currently focused, making major investments," he said.

      Another aspect to highlight is that, with the entry into operation of this system, Paraguay is interconnecting with the countries of the region, i.e. with Brazil, Argentina and Uruguay. "We are already in technical conditions so that tomorrow the electrical systems can be integrated and any negotiation of energy sales can be carried out through these networks", said the ANDE head.

      In order to achieve the synchronized operation of the National Interconnected System (SIN), it was necessary to install and put into service a modern and powerful platform for protection, control and real-time monitoring of the electric system, which constitutes a state-of-the-art technological solution, thus safeguarding the operational safety of the entire electric grid.

      On the other hand, in Itaipu the project required the activation, for the first time since its construction, of the power system stabilizers in the 50 Hz generators.
