State Grid Puts into Operation Two Power Transmission Projects in Brazil

The SUL2 transmission project of CPFL Energia S.A. (“CPFL”), a listed company holding company of State Grid Corporation of China (State Grid) in Brazil, and the Luziania substation expansion project of State Grid Brazil Holding S.A. (SGBH) were recently put into operation. The two projects provide power supply respectively to Rio Grande do Sul and Federal District of Brasilia, two of the companys’ major operating regions in Brazil, significantly improving the stability of regional power supply and promoting local economic development.

In December 2018, CPFL participated in the No. 004 transmission auction held by the ANEEL, and successfully won the bids for two projects, namely section 5 (SUL1) and 11 (SUL2). The SUL2 transmission project is located in Rio Grande do Sul and started construction in February 2020. It includes two new 230 kV substations, 66 km of 230 kV single-circuit transmission lines, 8 km of 230 kV single-circuit underground cables and the expansion of a 230 kV substation. On March 11, Brazil’s National Electrical System Operator (ONS) confirmed that the entire project entered into commercial operation, which was the last one of all the transmission concessions won by CPFL in 2018.

The Luziania substation is located in the state of Goiás in central Brazil, with a voltage level of 500 kV. Its expansion project started construction in February 2022, including a new bus reactor with a capacity of 135 MVar and the expansion of corresponding bays. On March 13, the project was put into commercial operation, 68 days ahead of ANEEL’s schedule. It was the first infrastructure project put into operation by SGBH this year, laying a good foundation for the company to complete the annual construction plan.

During the construction of the above projects, CPFL and SGBH managed the cost control well, overcame the impact of the sharp price increase of related equipment and raw materials in Brazil, and completed the construction within the approved budget. The two companies also recorded “zero-accident” by rationally optimizing the project plans, effectively deploying construction resources, and focusing on on-site quality and safety control.

State Grid will continue to support CPFL and SGBH in summarizing project construction experience, steadily advancing the annual construction plan, and ensuring that follow-up projects will be put into operation on schedule. (Source: State Grid International Development Co., Ltd.)
