The overcharging scandal prompted the resignation of former Energy Minister Diego Pardow, with Álvaro García assuming the position as biminister overseeing Energy and Economy. García emphasized the government’s commitment to automatic and comprehensive restitution of undue costs. Initial investigations revealed that the Comisión Nacional de Energía (CNE) had compounded tariff errors by applying both the Consumer Price Index (CPI) and a non-adjustable interest rate in tandem, thereby inflating prices. Transelec’s notification to CNE about asset overvaluation led to audits coordinated by the Coordinador Eléctrico Nacional and further regulatory scrutiny.
Authorities identified that several transmission companies lacked sufficient verification for their asset valuations, prompting demands for additional documentation and the initiation of similar audit procedures across the sector. Despite earlier tender processes to address these gaps, including a June 2025 bidding that was declared void and a subsequent successful one in November, uncertainties remain about the full extent of reimbursements pending audit conclusions. The Government has stated Transelec must reimburse any additional funds found to be charged incorrectly beyond current refunds.
This corrective measure marks a significant regulatory intervention aimed at restoring billing accuracy and consumer confidence in Chile’s electricity market, with ongoing oversight expected to reinforce transparency and compliance within the generation and transmission segments.
