State Grid commissions two power transmission projects in Brazil

The SUL2 transmission project of CPFL Energia, a company controlled by the State Grid Corporation of China in Brazil, and the expansion project of the Luziânia substation of State Grid Brazil Holding SA (SGBH) recently came into operation.

The two projects provide power supply respectively to Rio Grande do Sul and the Federal District of Brasilia, two of the company’s main operating regions in Brazil, significantly improving the stability of regional power supply and promoting local economic development.

In December 2018, CPFL successfully won the tenders for two projects, namely section 5 (SUL1) and section 11 (SUL2). The SUL2 transmission project is located in Rio Grande do Sul and construction began 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 one 230 kV substation.

On March 11, the National Operator of the Electric System (ONS) of Brazil confirmed the entry into commercial operation of the entire project, which was the last of all the transmission concessions won by CPFL in 2018.

China and Brazil bet on more trade and investment projects

The Luziânia substation is located in the state of Goiás, in central Brazil, with a voltage level of 500 kV. Its expansion project began construction in February 2022, including a new rod reactor with a capacity of 135 MVar and the expansion of the corresponding bays.

On March 13, the project entered commercial operation, 68 days ahead of 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 mentioned projects, CPFL and SGBH managed cost control well, overcame the impact of the sharp increase in the prices of equipment and related raw materials in Brazil, and completed the construction within the approved budget.

The two companies also recorded “zero accidents” by rationally optimizing project plans, effectively deploying construction resources, and focusing on quality control and on-site safety.

As reported in a statementState Grid will continue to support CPFL and SGBH in synthesizing project construction experience, steadily advancing the annual construction plan, and ensuring follow-up projects come online on schedule.
