The UTE William Arjona thermal power plant, located in Campo Grande, has secured the green light from Aneel to operate indefinitely, consolidating its position in the sector after years of temporary contracts.
The National Electric Energy Agency (Aneel) has formalized a significant regulatory change for UTE William Arjona, a plant controlled by Delta Geração. With the presentation of a long-term natural gas supply contract signed with Galp Energia Brasil, the facility no longer relies on periodic renewals to maintain its activities.
The legal certainty of the enterprise, which operates in Campo Grande (MS), was reinforced by aligning fuel supply with the Capacity Reserve Contract (CRCap). The new agreement guarantees supply until mid-2041, ending a cycle of uncertainty that had persisted since 2021, when the plant began depending on successive authorizations for energy dispatch.
Stability and Operational History
The plant, which stood out as a winner of the first Capacity Reserve Auction held in late 2021, plays a strategic role in the national electric system. Delta Geração‘s recent history shows a continuous effort to make the plant viable:
The new contractual configuration, validated by the regulatory agency, represents a milestone for the sustainability of the operation, overcoming the limitations of the temporary fuel contracts that governed the unit in recent years.
This stability is a fundamental step for the company, which had already obtained authorization from the Monitoring Committee for the Electric Sector (CMSE) to advance the start of its supply in 2025, demonstrating the generator’s commitment to keeping the plant available to meet load when requested.
Resumption in Minas Gerais
While the thermal plant in Mato Grosso do Sul celebrates the reduction in red tape, the hydroelectric generation sector also reports progress in asset recovery. Cemig has received approval to restart generating unit UG3 at UHE Paciência, located in Matias Barbosa (MG).
This unit is part of a group of generators that had been out of operation due to the severe impacts of flooding in Minas Gerais. The storms caused flooding in the powerhouse and compromised essential equipment, such as generators and auxiliary systems. With this release, UHE Paciência recovers most of its installed capacity, restoring the normalcy required for the plant’s operation.
