**By Brazil Stock Guide –** The renewal of natural gas distribution concessions in Rio de Janeiro must be conducted with **full transparency, broad public participation and strict legal certainty**, according to the **Brazilian Institute of Oil, Gas and Biofuels (IBP)**, as the issue gains clear political overtones.

State regulator **Agenersa** is set to weigh the future of concessions held by **CEG** and **CEG Rio**, while the Rio de Janeiro government moves to define the outcome by **February**, a timeline that coincides with mounting electoral pressure.

**Strategic asset, electoral backdrop**
The concessions, awarded in **1997** for a **30-year term** and expiring in **July 2027**, cover gas distribution to roughly **one million consumers** and could inject **billions of reais** into state coffers. The debate unfolds against the backdrop of Brazil’s **2026 elections**. Governor **Cláudio Castro (PL)** is expected to seek a **Senate seat**, heightening sensitivity around any decision that could affect **tariffs, public revenues and long-term infrastructure contracts**.

**Renew or re-tender**
The state government hired **Fundação Getulio Vargas (FGV)** to prepare technical studies assessing whether extending the existing contracts with Spain’s **Naturgy** or launching a **new bidding process** would be more advantageous. Officials are reviewing the **economic valuation of the concessions**, the treatment of **non-amortized assets** and the **legal robustness** of each option, with the stated goal of maximizing value for the state while limiting future litigation risks.

**Transparency under strain**
According to **IBP**, election-year dynamics increase the risk of **rushed or opaque decisions**. The institute argues that any move on the concessions should be preceded by **robust public hearings** and **full disclosure of technical, economic and contractual information**. State lawmakers have echoed those concerns, warning that an **automatic renewal in an electoral year** could undermine transparency, while a **new tender** could offer clearer commitments on investments, financial targets and returns to the state.

**Legal and tariff risks**
The process is further complicated by an ongoing review by the **Rio de Janeiro State Court of Accounts (TCE-RJ)** into the legality of the renewal procedure. At the same time, **tariff impacts** remain politically sensitive. State officials have publicly stated that any decision must avoid **sharp increases** that could hurt **industrial competitiveness** or weigh on **household gas bills** — a critical issue ahead of the elections.

IBP maintains that the final decision must align with **Brazil’s Gas Law (Law No. 14,134/2021)**, based on **updated data** and **credible investment plans**. In a context where **political incentives are clearly in play**, the institute argues that only a **transparent, technically sound and legally solid process** can preserve **regulatory credibility**, reduce **judicial risk** and ensure long-term stability for **Rio de Janeiro’s gas market**.
