Business Overview
Central Puerto S.A. is an integrated Argentine energy company primarily engaged in electric power generation across thermal, hydroelectric, and renewable sources. The company’s revenue derives mainly from energy sales in the Wholesale Electricity Market (MEM), with segments spanning thermal power plants, hydroelectric concessions, and renewable projects including wind and solar farms.
Performance Analysis
In Q2 2025, Central Puerto reported adjusted EBITDA of $61.4 million, marking a 32% decrease from $89.9 million in Q1 2025 but a 35% increase year-over-year. The last twelve months’ adjusted EBITDA reached $309.9 million, 8% above full-year 2024. Revenues were $179.6 million, up 7% year-over-year but down 8% sequentially, reflecting lower generation volumes and the seasonality of spot capacity charges.
The quarter’s 4,372 GWh generation volume declined 24% sequentially and 12% year-over-year, primarily due to scheduled and unscheduled maintenance at key assets including the Central Costanera Mitsubishi combined cycle and the Central Puerto steam turbine 6. These maintenance activities increased operating expenses by approximately $18-20 million, negatively impacting margins. However, the maintenance was necessary to restore asset availability to targeted levels above 90%, supporting long-term operational efficiency.
- Volume and Revenue Pressure: Maintenance and seasonal spot market dynamics led to lower generation volumes and capacity charge revenues.
- Fuel Procurement Strategy: Self-managed fuel procurement added $18.4 million in revenue, partially offsetting volume declines.
- Capital Expenditure Focus: $102.4 million spent in H1 2025 mainly on capacity expansion projects nearing completion.
Overall, the quarter reflects a temporary operational setback amid ongoing growth investments and a regulatory environment adjusting to inflation and market reforms.
Executive Commentary
"We performed a big maintenance on the two boilers of the two GTs, which was extraordinary. We are not expecting to recover that money from the insurance company. But we put those boilers in good condition for the next 20 years, aiming for availability over 90 to 95 percent."
Enrique Terranio, Chief Financial Officer
"Our growth plan is already adding around 300 MW of installed capacity, with Brigadier López combined cycle and San Carlos Solar Farm nearing conclusion, and Alamitos Wind Farm in design phase."
Fernando Bonet, Chief Executive Officer
Strategic Positioning
1. Capacity Expansion Pipeline
Central Puerto is actively expanding installed capacity with nearly 300 MW under development. The Brigadier López combined cycle project adds 140 MW with an expected commercial operation date (COD) in Q4 2025. The San Carlos Solar project contributes 15 MW, also targeting year-end COD. The Alamitos Wind project, planned for 130 to 150 MW, is in the bidding phase with construction slated for early 2026, representing a strategic move into renewable energy growth.
2. Operational Efficiency and Asset Reliability
The company prioritized restoring asset availability through planned and extraordinary maintenance, notably at Central Costanera’s Mitsubishi combined cycle and Central Puerto’s steam turbine 6. Though costly and impacting short-term earnings, these efforts aim to secure long-term generation reliability and improved operational standards aligned with Central Puerto’s internal benchmarks.
3. Regulatory Environment and Market Reforms
Recent decrees and resolutions from the Argentine Energy Secretariat have introduced monthly inflation adjustments to spot prices and extended hydroelectric concessions, notably Piedra del Águila’s term until late 2025 with potential further extension. The government’s evolving approach to auctions for hydro, thermal, and battery storage capacity introduces uncertainty but also opportunities for market participation and revenue stabilization.
4. Financial Position and Capital Allocation
Central Puerto maintains a strong balance sheet with net leverage of 0.56 times last twelve months adjusted EBITDA. Capital expenditures of $102.4 million in H1 2025 were fully funded by operating cash flow, reflecting disciplined financial management. Remaining capex includes approximately $35-40 million for Brigadier López and $2-3 million for San Carlos, with potential early spending acceleration for Alamitos.
5. Fuel Procurement Flexibility
The company’s ability to self-manage fuel procurement under Resolution 21 has enhanced revenue by $18.4 million in Q2, partially offsetting volume declines. This strategic flexibility supports margin management amid volatile fuel markets and regulatory shifts.
