The MME (Ministry of Mines and Energy) authorized UTE William Arjona to bring forward the start of its capacity reserve energy contract by almost a year.
Starting this month, the natural gas-fired power plant will contribute to the country's electricity supply security. Originally, the contract, signed at the 1st Capacity Reserve Auction of 2021, stipulated that supply would begin in July 2026.
With an installed capacity of 177 MW, the plant, located in Campo Grande, Mato Grosso do Sul, will initially operate four generating units, adding an additional 150 MW to the system. A fifth unit is expected to come online by the end of February 2026.
Acquired by the Delta Energia group in 2019, the thermoelectric plant underwent extensive modernization and resumed operations in 2021, a year marked by the water crisis that led the government to hold an emergency auction. In the 2021 LARcap, the plant secured a 15-year supply contract, scheduled to expire on June 20, 2041.
"By bringing forward the William Arjona TPP, we are able to contribute to the country's energy security and stability. We believe in the balance between intermittent and dispatchable sources as a way to provide operational reliability for the expansion of a sector essential to Brazil's development," says Lourival Teixeira, president of Delta Geração.
The ONS (National System Operator) has indicated the need to activate thermoelectric plants in the second half of the year, especially to guarantee power in the early evening, when demand increases and the supply of intermittent renewable sources decreases.
