Brazil’s Retail Electricity Market Opening Exposes Credit and Liquidity Risks, Study Warns
A study of Brazil’s expanding retail electricity market finds high payment delinquency and customer churn, raising concerns over consumer protection and the need for stricter regulatory oversight.
Brazil’s planned retail electricity market opening faces significant credit and liquidity risks, according to a new study tracking 88,000 consumer units in subscription-based solar generation schemes.
The research, led by Guilherme Susteras and Alexandre Bueno using data from Wattio and Abrasel, found a 17% average monthly payment delinquency rate and 4% monthly customer churn from January 2025 to May 2026. Annualized, this churn equates to more than 40% turnover in the customer base, raising red flags about financial sustainability for market participants.
Under Brazil’s current timeline, industrial and commercial consumers will be able to migrate to the free market from November 25, 2027, with residential customers following a year later. The study’s findings suggest that many electricity retailers may struggle to manage cash flow and credit risk in such a competitive environment.
The study highlights that elevated delinquency rates could undermine retailers’ liquidity, while high churn increases customer acquisition costs and operational complexity. Excessive contracting by retailers could also expose them to volatility in Brazil’s short-term electricity market, amplifying systemic risk.
The report points to information asymmetry as a further challenge, with some consumers potentially misunderstanding contract terms or underestimating risks, especially in novel models like distributed solar generation. Average annual discounts for these schemes reached 17%, rising to 19% in 2026, which may encourage switching but complicate long-term planning for providers.
For Europe-based investors and policymakers, Brazil’s experience offers a cautionary example as electricity markets liberalize globally. The risks identified—ranging from retailer bankruptcies to reliance on suppliers of last resort—underscore the need for robust regulatory oversight and effective consumer protection frameworks.
Opportunities exist for improved credit assessment and liquidity management, according to consultancy Allez Estratégia. Enhanced governance and transparency could stabilize the sector, while targeted consumer education initiatives may help close information gaps and strengthen market confidence.
