Enel Chile S. A. engages in the generation and distribution of electricity in Chile through its subsidiaries. The company operates a diversified generation portfolio that includes hydroelectric, wind, solar, geothermal, thermal and battery storage facilities, with a total net installed capacity of 8,904 megawatts as of December 31, 2025. Its distribution business delivers power to approximately 2.2 million residential, commercial, industrial and other customers within a 2,105 square kilometre concession area covering 33 municipalities in the Santiago Metropolitan Region.

Enel Chile S. A. generates revenue primarily from the sale of electricity to regulated and unregulated customers and from participation in the wholesale power market. In 2025, the generation segment contributed $3,283 million in revenue, the distribution segment contributed $1,784 million, and other non‑electricity activities accounted for approximately one percent of total revenue. Revenue is derived from electricity sales under long‑term contracts, spot market transactions and regulated tariffs applied to distribution customers.

The company operates through the following segments: Electricity Generation and Electricity Distribution.

• Electricity Generation: This segment produces electricity from a mix of renewable sources and thermal plants, operates 76 power plants across Chile and sells output to distribution companies, large industrial users and the spot market, while also participating in capacity auctions and long‑term supply tenders.

• Electricity Distribution: This segment manages the concession‑based network that delivers electricity to end users, maintains over 18,000 kilometres of medium and low voltage lines, provides service to approximately 2.2 million customers and earns revenue through regulated tariffs that recover electricity purchase costs, transmission charges and a value‑added distribution component.

Enel Chile S. A. holds a leading position in the Chilean electricity sector, representing about 22 percent of the national interconnected system’s installed capacity and ranking as the largest electricity commercialization company in the country. Its competitive advantages stem from a balanced renewable‑heavy portfolio, access to liquefied natural gas terminals for flexible thermal generation and a regulated distribution franchise that serves a dense urban load centre.

The generation segment’s top customers include CGE (Compañía General de Electricidad S. A.) and Enel Distribución Chile, each accounting for ten percent or more of the segment’s ordinary revenues in 2025. The distribution segment serves residential, commercial, industrial and other customers, primarily municipalities, within the Santiago Metropolitan Region, with no individual customer disclosed as material to the segment’s revenue.
