Operating Margin Drivers
AES CORP · 2026-11-03 · Importance 58 · Surprise 56 · In source text
Consolidated operating margin increased $247 million, or 34%, in the third quarter of 2026 and $685 million, or 42%, for the first nine months compared with 2025. Renewables margin growth reflected higher spot sales and prices in Colombia amid El Niño-related unfavorable hydrological conditions, relatively favorable hydrology at the AES Chivor basin, and U.S. development services. Utilities margins benefited from higher retail rates, including AES Ohio’s 2024 DRC Settlement, and higher demand; Energy Infrastructure benefited from higher spot energy and capacity sales and prices. Lower contract sales volume, chiefly from the expiration of the Maritza PPA in Bulgaria, and higher depreciation partially offset the nine-month increase.
Key facts
- AES consolidated operating margin increased $685 million, or 42%, in the first nine months of 2026, primarily due to U.S. development services and Colombia spot sales, higher AES Ohio rates, and higher Energy Infrastructure spot-market sales and prices; lower Maritza contract sales volume and higher depreciation partly offset the increase. source
