This study analyzes the technical and economic effects of reducing the power limit for defining free customers in Chile: from five hundred kilowatts to one hundred kilowatts. First, the current regulation is reviewed to set the basis of the analysis. An international comparison with similar countries in the region is also presented as background. The analysis focuses on the impact on the electrical system, customer tariffs, and the national grid operator (Coordinador Eléctrico Nacional). The results show that (i) distribution companies would forgo estimated revenues of around four hundred million dollars if the limit is reduced to one hundred kilowatts by two thousand twenty-eight and all eligible customers opt to enter the free energy market, (ii) free customers could reduce their monthly bills by between twenty-one point one percent and thirty-five point seven percent compared to current bills, and (iii) the national grid operator will face the challenge of managing around one million sixty thousand five hundred three new contracts, which translates into an estimated demand of approximately four point five terawatthours per year.
