Pay your bill on time, get money back—if the habit sticks
Em um país onde o furto de energia e a inadimplência corroem silenciosamente o sistema elétrico, a Aneel autorizou nesta semana um experimento que aposta na reciprocidade em vez da punição: pague sua conta em dia e receba dinheiro de volta. A distribuidora Light, com 18 milhões de reais em jogo e dez mil consumidores cariocas como participantes, inaugura um modelo de sandbox regulatório que reconhece uma verdade antiga — que o cumprimento das regras, quando recompensado, pode alcançar onde a fiscalização sozinha não chega.
- O furto de energia e a inadimplência crônica sangram as finanças da Light e encarecem a conta de quem paga corretamente, criando uma injustiça sistêmica difícil de desfazer.
- A aprovação da Aneel abre uma janela de três anos para testar se incentivos financeiros — cashback e tarifas fixas mensais — conseguem mudar comportamentos arraigados em comunidades do Rio de Janeiro.
- Dois grupos distintos entram no programa: os bons pagadores, que ganham previsibilidade e recompensa, e os ex-irregulares que se regularizaram, apostando que a segunda chance pode consolidar a mudança.
- A tarifa fixa é a aposta mais ousada: ao eliminar a surpresa da conta alta, remove-se um dos principais pretextos para o não pagamento e cria-se um novo contrato de confiança entre distribuidora e consumidor.
- Se o piloto funcionar, outras distribuidoras poderão replicar o modelo; se fracassar, a Light absorve o custo — e o sistema aprende sem comprometer o restante do mercado.
A Aneel aprovou nesta terça-feira, 24 de setembro, o programa piloto da Light que oferece cashback a consumidores residenciais no Rio de Janeiro que pagarem suas contas em dia. O experimento, com duração de três anos, envolve dez mil domicílios e um investimento de até 24 milhões de reais entre regulador e empresa.
O problema que a iniciativa tenta resolver é antigo: a Light perde receita tanto pela inadimplência quanto pelo furto de energia — o chamado "gato" —, práticas que distorcem o mercado e oneram quem cumpre suas obrigações. A lógica do programa é inverter essa equação oferecendo vantagens concretas em vez de apenas punições.
Os participantes serão divididos em dois grupos. O primeiro reúne clientes que já pagam regularmente; o segundo, consumidores que tiveram irregularidades nos últimos dois anos, mas que normalizaram sua situação. Ambos receberão uma tarifa fixa mensal — o mesmo valor independentemente do consumo — e recompensas em cashback pela pontualidade.
A tarifa fixa é o elemento mais inovador: ao garantir previsibilidade, ela elimina o choque de contas sazonais elevadas, um dos argumentos mais usados para justificar o não pagamento. A Light terá a obrigação de explicar claramente as regras antes da adesão e de detalhar o modelo nas faturas.
O programa opera dentro de um sandbox regulatório, mecanismo que permite à distribuidora funcionar sob regras tarifárias diferentes das convencionais por tempo limitado, com o objetivo explícito de testar inovações. Caso os resultados sejam positivos, outras distribuidoras poderão adotar modelos semelhantes. Caso contrário, o ônus recai sobre a empresa. Os próximos três anos dirão se a reciprocidade é, de fato, mais eficaz do que a coerção.
Brazil's energy regulator gave the green light this week to an experiment that sounds simple enough: pay your electric bill on time, get money back. The Aneel, the country's national electricity agency, approved Light's pilot program on Tuesday, September 24th, betting that ten thousand residential customers in Rio de Janeiro will change their behavior if the company sweetens the deal.
The problem Light is trying to solve is old and stubborn. Across its service territory, the utility bleeds money from two directions at once: customers who don't pay their bills, and customers who steal electricity outright—the "gato," the illegal tap into the grid that has become almost a way of life in certain neighborhoods. These twin drains on the system cost the company dearly and distort the market for everyone else. So Aneel approved a three-year test to see if incentives might work where enforcement alone has not.
The mechanics are straightforward. Light will spend eighteen million reais on the program, with the company itself kicking in up to six million more. Ten thousand households will be divided into two groups. The first consists of customers who already pay regularly—the utility's reliable base. They'll get a fixed monthly bill that doesn't fluctuate with consumption, plus a cashback reward for staying current. The second group is trickier: these are people caught doing something irregular in the past two years—stealing power, tampering with meters, whatever—but who have since gotten straight. They also get the fixed billing model.
The fixed-rate approach is the real innovation here. Instead of a bill that rises and falls with how much electricity you use, these customers will know exactly what they owe each month. For the utility, this creates predictability too. And Aneel sees another benefit: the fixed rate removes one excuse people use for not paying—the shock of a high bill in summer or winter. If you know it's always the same, you can budget for it.
Light will have to be transparent about the rules. The company must explain the different billing structure to participants before they enroll, and the invoices themselves will need to clearly show how the payment system works. There's no room for confusion or hidden terms.
What makes this experiment significant is its legal wrapper. Aneel approved it under what's called a "regulatory sandbox"—a framework that lets a utility operate under different tariff rules than everyone else for a limited time, specifically to test whether an innovation actually works. If Light's pilot succeeds, other distributors can ask to run similar programs. If it fails, the company absorbs the loss and the system reverts to normal. It's a controlled way to learn.
The stakes are real. Energy theft and non-payment are not small problems in Brazil. They distort prices for customers who do pay, they strain utility finances, and they signal that the system itself is fragile. Whether a cashback and a fixed bill can change that calculus—whether people will stay honest and current because they're getting something back—will become clear over the next three years. The test begins now.

La Conversación del Hearth Otra perspectiva de la historia
Why does Light think money back will work when enforcement hasn't?
Because enforcement alone assumes people are rational actors with full information. Most aren't. A person in a favela stealing power isn't doing it because they're defiant—they're doing it because the official bill is unaffordable and unpredictable. A fixed rate removes the shock. Cashback removes the feeling that the system is rigged against them.
But won't people just game it? Sign up for the incentive, collect the cashback, then stop paying?
That's the test. Aneel is betting that once you've been regular for a while, the habit sticks. And the company can always cut people off if they default. But the real insight is that Light is trying to move upstream—to prevent the theft and non-payment before it starts, not punish it after.
Why divide the program into two groups?
The first group—regular payers—they're the control. They prove the model works for people who already have the capacity to pay. The second group is the real experiment. These are people who were caught stealing or not paying but have since reformed. If they stay regular under this system, it proves the incentive works on the people who need it most.
What happens after three years?
That depends on the data. If the default rate drops significantly and theft stays down, Aneel will probably let other utilities try it. If it doesn't work, Light eats the cost and the program ends. Either way, Brazil learns something about whether you can buy compliance.
Is eighteen million reais a lot of money for this?
For a utility the size of Light, it's not enormous. But it's real skin in the game. The company is betting that preventing future losses is worth the upfront cost. That's the whole logic of the sandbox—you invest now to prove the model works, then scale it if it does.
