Compañía de Alumbrado Eléctrico de San Salvador, S.A. de C.V. (CAESS)

—

What it is

CAESS was organised on 17 November 1890 under the laws of El Salvador — making it one of the oldest power companies in Central America. It was born at the initiative of a group of Salvadorans with the purpose of distributing and commercialising electrical energy.

Its core job is to distribute electricity to municipalities and urban districts in San Salvador, Chalatenango, Cabañas and Cuscatlán. Today it serves more than 653,000 customers across approximately 4,637 km² of urban, rural, commercial and industrial territory.

CAESS also owns approximately 98.28% of Distribuidora Eléctrica de Usulután, S.A. de C.V. (“DEUSEM”), another power distributor, and files consolidated accounts that include that subsidiary.

Together with its sibling distributors CLESA and EEO, the AES El Salvador group serves about 80% of the national electricity market and supplies more than one million customers.

Who owns it

CAESS is a subsidiary of AES Empresa Eléctrica de El Salvador, Ltda. de C.V., which is in turn a subsidiary of The AES Corporation — the ultimate controlling entity — and the company operates under AES group accounting and management policies.

About 24.89% of CAESS shares trade on the Bolsa de Valores de El Salvador, making it a public company, while AES holds the remaining ~75.11%.

The parent itself is now mid-transaction: AES Corporation has reached a definitive agreement to be acquired by a private-equity consortium led by Global Infrastructure Partners (GIP) — BlackRock’s infrastructure platform — and EQT Infrastructure, in a deal valued at approximately $33.4 billion including debt. This puts critical energy assets across Latin America, including El Salvador’s distribution network, under the control of those investment funds.

Who runs it

Not published: the individual names of CAESS’s board directors, president/CEO and CFO are not disclosed in the BVES issuer directory (bolsadevalores.com.sv, issuer ID 55) or in the SSF’s public filings registry in an extractable form at the time of research. El Salvador’s Ley del Mercado de Valores (Art.

75) requires listed issuers to publish periodic financial statements and material events; governance disclosures at director-name level are handled through the BVES’s “Junta Directiva” tab, which did not return detailed data in the searches conducted. The AES El Salvador group manages all four distribution companies — CAESS, CLESA, EEO and DEUSEM — under a shared corporate governance structure, with group-level management information published at aes-elsalvador.com.

The money, in plain words

In the first half of 2025, the AES El Salvador group’s combined revenues from power distribution reached $533.8M — a year-on-year rise of 8% — with CAESS generating 51% of that total, AES CLESA 28% and EEO 21%. That puts CAESS’s half-year revenue at roughly $272M and an annualised rate of approximately $545M (our calculation, proportional share of H1 2025 group revenues).

Of the group’s energy sales, 44% comes from residential customers, 23% from industry, 18% from commerce and 13% from government sales. At the full-year 2024 close, the group’s operating cash-flow proxy — the money the business generates before interest and tax — reached $186M, growing 18% year-on-year, driven by higher revenues.

The debt load is meaningful: the ratio of total debt to total assets stood at 65.0% at December 2024 (down from 66.7% at end-2023), of which roughly half is financial debt, mostly long-term. Even so, the group’s ability to cover its interest bill comfortably — the EBIT-to-interest-expense ratio was 4.9 times — and its debt-to-EBITDA of 2.1 times suggest the financial burden is manageable.

Not published: standalone FY2024 revenue, net profit, net margin and return on equity for CAESS as a separate legal entity are not available in an extractable form from the BVES filings page (bolsadevalores.com.sv/emisores/ID=55) or the SSF regulator (ssf.gob.sv) at the time of research. The semi-annual Q2 2024 balance sheet filed with BVES shows dividends payable of $10.1M and short-term borrowings of $54.8M but does not reproduce the income statement in the search-accessible text.

The above group-level ratios are drawn from the Moodys Local El Salvador rating report of April 2025, which covers CAESS, CLESA and EEO consolidated as “AES El Salvador.”

What it is doing now

In October 2023, CAESS, AES CLESA and EEO jointly launched a securitisation programme of up to $315M, placing approximately $146.5M by December 2024. The proceeds are being used to repay the group’s syndicated bank loan early, gradually shifting the debt mix from bank credit to capital-market instruments.

By mid-2025, the group’s operating cash generation had dipped 10% year-on-year to $92M for the first half, though interest coverage remained solid at 3.9 times and the debt-to-operating-cash ratio held at 2.2 times. Capital spending — the money flowing into grid upgrades — runs at $40–50M per year, with a focus on digitalisation and smart-grid projects.

In El Salvador, electricity tariffs are set not by the company but by the national energy regulator SIGET and the Dirección General de Energía, Hidrocarburos y Minas; during 2026 those authorities have held rates stable despite international energy-price swings.

What to watch

• The AES Corp sale. The $33.4B acquisition of AES Corporation by a consortium of BlackRock’s GIP and EQT Infrastructure would make CAESS’s ultimate parent a private entity. The critical moment for El Salvador will come when the new consortium decides its regional strategy — a future divestiture of Latin American assets could put CAESS’s ownership up for grabs again.
• Tariff cycle. CAESS earns regulated rates; any future review by SIGET could move revenue sharply up or down without management being able to respond.
• Debt maturation. The group’s syndicated bank loan carries a floating rate indexed to three-month SOFR plus 5%, with staggered maturities running through 2027. Rising dollar interest rates feed directly into funding costs.
• Disclosure quality. For a listed company, the public availability of standalone annual revenue and net-profit figures is thin; investors seeking a precise picture currently rely on group-level rating reports rather than issuer filings.
