Paraguay: Itaipu Binacional has received equipment manufactured by WEG for the expansion of the Right Bank Substation, located on the Paraguayan side of the Itaipu hydroelectric plant complex. The contract, signed in partnership with a local contractor, includes products aimed at meeting the energy demand and reinforcing the company’s commitment to sustainability by using a vegetable oil transformer. This choice reduces the environmental impact when compared to mineral oil, as it is biodegradable and comes from natural sources.
This project is part of the expansion of Sector 1 of the Right Bank Substation, 66 and 23 kV Yard, intended to adjust the energy supply for feeding the Auxiliary Services of the Itaipu Hydroelectric Plant complex. The equipment was delivered in the second half of 2024.
The scope of the equipment manufactured and supplied by WEG includes a vegetable oil transformer (66/23 kV, 10 MVA), a dry-type transformer (23/13.8 kV, 5 MVA), vegetable oil insulated pedestal auxiliary transformers (23000/220 V, 75 kVA), a tripolar switch (72.5 kV, 1250 A, 25 kA), and a complete SPCS system with panel supply. The first vegetable oil insulated transformer to be used by Itaipu is a highlight of the supply. The technology was developed from a comprehensive study carried out by Itaipu’s Technical Directory, which evaluated both technical and environmental aspects. Vegetable oil has a higher flash point, which means increased operational safety, and it is a renewable and less environmentally impactful alternative.
In addition to the equipment manufactured by WEG, other equipment and components complete the supply: lightning arresters, Hybrid Compact Module, Medium Voltage Cubicles, and peripheral components like low-voltage electrical panels, fire detection and suppression system with nebulized water, complete air conditioning system for the new building, etc., all under WEG’s management.
