Chile’s Competition Court Fines Metrogas About US$3.6 Million

On 12 August 2026, Chile's Competition Court, known as the Tribunal de Defensa de la Libre Competencia (TDLC), imposed a fine of approximately US$3.6 million on Metrogas, the country's largest natural-gas distributor. The tribunal ruled that Metrogas had abused its dominant position in the gas transport market by overcharging customers who had no alternative options.

The court ordered Metrogas to scrap the excessive pipeline charge, which related to the price of moving gas to a large power plant. This charge was deemed unreasonably high due to the company's significant market power. While overcharging itself is not illegal, it becomes problematic when a dominant company practices it on customers with limited alternatives.

Generadora Metropolitana, the company operating the Nueva Renca thermoelectric power plant, brought a private lawsuit against Metrogas after the transport charge increased sharply. The power plant relied heavily on Metrogas for its fuel delivery, making the price a crucial factor in its operations. The case was initiated by the power plant, not by any government watchdog.

Chilean courts impose fines in UTA, a unit that tracks inflation, rather than in fixed peso amounts. The 3,800 UTA fine translates to roughly CLP 3.2 billion or US$3.6 million at mid-August 2026 exchange rates. The money is paid to the Chilean state treasury, known as the Fisco, and does not go directly to the company that complained.

The TDLC's ruling aims not only to punish Metrogas but also to deter other dominant firms from abusing their power. Competition law exists to prevent large players from charging excessively and harming customers. By imposing the fine and ordering Metrogas to renegotiate a fairer transport charge, the tribunal sought to ensure a more equitable pricing structure in the gas market. The outcome of this ruling may lead to lower costs for households and businesses that rely on Metrogas for their energy needs.
