ANP Decision Maintains Regulatory Pressure on Petrobras, Requires Action Plan for UTGCA Adjustment, and Revives Debate on Investments, Natural Gas Quality, and Pre-Salt Rules in São Paulo
On December 29, 2025, the board of the National Agency of Petroleum, Natural Gas and Biofuels (ANP) rejected the reconsideration request made by Petrobras and maintained the requirement for an action plan to adjust the Caraguatatuba Gas Treatment Unit (UTGCA), located in São Paulo, to regulatory specifications for supplying natural gas.
According to a report published by Eixos Agency, the decision was made in an extraordinary meeting and reinforces the regulatory stance of the agency regarding compliance with technical standards in the sector. The plan must be submitted by February 21, a necessary condition for the temporary renewal of the special authorization that allows the unit to operate outside the parameters required by current regulation.
ANP Decision Reinforces Requirements for UTGCA
The ANP’s understanding increases pressure on investments in pre-salt gas treatment, while signaling greater institutional rigor for the entire market.

The ANP fully followed the recommendation from the technical areas when denying the appeal filed by Petrobras, maintaining the determination that UTGCA submit a structured plan that allows the supply of natural gas in accordance with regulatory specifications.
The rapporteur for the process, director Pietro Mendes, highlighted that insufficient evidence was presented to prove definitive technical or economic infeasibility for adjusting the unit. According to him, the situation reflects a business choice to postpone investments, rather than an unavoidable structural limitation.
The agency believes that strategic decisions cannot override industry rules, especially in a market undergoing opening and regulatory maturation.
ANP Rejects Suspension of Natural Gas Classification
In addition to the reconsideration request, Petrobras requested the suspension of Article 4 of special authorization No. 713/2025, which explicitly classifies as non-compliant the natural gas coming from UTGCA. The request was denied by ANP on the grounds of lack of “just fear of damage difficult or uncertain to repair”.
For the agency, regulatory classification serves an essential function of transparency and publicity, allowing market agents to have full knowledge of the characteristics of the offered product.
The decision reinforces that regulation should not be used as a tool for contractual shielding, but rather as a mechanism for information and market balance.
Regulatory Transparency and Petrobras’s Position
During the analysis of the process, the rapporteur highlighted that Petrobras itself acknowledges that the interchangeability parameters of natural gas were respected, ensuring no operational impacts for transporters and end consumers.
According to Pietro Mendes, if there is no proven technical impact, classification as non-compliant should not lead to the contractual effects alleged by the company. For the ANP, the request sought to create a regulatory shield against potential future liabilities, regardless of the occurrence of damages. The agency’s understanding strengthens legal certainty, by clearly separating the regulatory sphere from the contractual sphere.
Special Authorization and Technical Limits of UTGCA
The UTGCA has been operating since 2020 based on special authorizations that allow the offering of natural gas with a minimum methane content of 80%, below the regulatory limit of 85% set by the ANP. These authorizations have always been exceptional and temporary.
The submission of an action plan became a condition for the renewal of the authorization for up to eight months. For the agency, the prolonged maintenance of this exceptional regime compromises regulatory predictability and creates distortions in the market. Continuous exceptions weaken the competitive environment, especially in a sector seeking greater transparency and predictability.
Petrobras, Pre-Salt, and Change in Natural Gas Profile
Petrobras asserts that the UTGCA was originally designed to process post-salt gas, with a composition different from that currently predominant. Today, the unit primarily operates with gas associated with the pre-salt, which has a higher content of heavy hydrocarbons.
This change in feedstock profile requires relevant technical adjustments. However, the ANP claims that the company has not conclusively proven the technical or economic impossibility of adjusting the unit for the regular supply of natural gas within the specifications. The agency understands that production evolution requires updating assets, and that this cost is part of business risk.
Cancellation of Petrobras’s UTGCA Modernization Project
In 2020, Petrobras canceled the modernization project of UTGCA, citing economic-financial infeasibility. According to information in the regulatory process, the project is currently undergoing preliminary reassessment.
For the ANP, the cancellation of the project does not, by itself, prove the definitive impossibility of adjustment. The agency maintains that investment decisions are part of business strategy and do not justify the permanent non-compliance with the supply standards of natural gas. The case highlights the conflict between adaptation costs and regulatory requirements, especially in older assets.
Impacts of ANP’s Decision on Investments
The decision increases pressure on Petrobras at a time of reorganization of the strategy for the gas market. Adjusting the UTGCA may require significant investments, impacting timelines, budget, and capital allocation.
At the same time, the positioning of the ANP sends a clear signal to the market that the rules will be applied uniformly, regardless of the operator. This reduces competitive asymmetries and strengthens institutional credibility. Regulatory predictability is seen as a key factor in attracting new players to the gas sector.
Reflections on the Natural Gas Market in São Paulo
São Paulo concentrates one of the largest industrial demands for natural gas in the country. Any uncertainty in supply or product quality directly impacts the energy planning of industries, distributors, and free consumers.
The requirement for adjusting UTGCA aims to ensure that the offered gas is fully aligned with technical standards, reducing operational and contractual risks along the chain. The decision prioritizes system reliability, even if it entails additional costs in the short term.
What Does the Decision Reveal About the Future of the Sector?
The rejection of Petrobras‘ appeal by the ANP evidences a movement to strengthen institutional regulation of natural gas in Brazil. By requiring an action plan for UTGCA, the agency reaffirms that exceptional authorizations cannot become permanent.
This episode also signals that changes in production profile, such as a greater participation of pre-salt, require compatible technical responses. For the market, the message is clear: compliance with the rules is an essential condition for stability and expansion of the energy sector.
