The minute
- President Lula signed PL 278/2026 on September 15, creating the Regime Especial de Tributação para Serviços de Datacenter (Redata), a special tax regime for datacenter services in Brazil.
- A Senate drafting amendment replaced the requirement for “clean” or “renewable” energy sources with “renewable or low-emission” sources, opening a path for natural gas to qualify for the tax benefits.
- The regulatory decree is expected to be published the same day, but an interministerial portaria will still need to define the technical parameters for what counts as low emission, with options ranging from excluding gas entirely to accepting it with carbon offset mechanisms.
Why it matters: Brazil is positioning itself as a destination for hyperscale datacenter investment, but the Redata’s real impact depends on a regulatory detail that is still being fought over inside the government. Whether natural gas qualifies as “low emission” will shape which energy sources supply new datacenter loads, and that outcome will redirect billions in infrastructure investment toward either gas pipelines or renewable generation and battery storage.
Who wins and who loses
The lines in this dispute are clearly drawn. On one side, northeastern states like Pernambuco and Sergipe, along with gas distributors, pushed to include natural gas. These states have gas infrastructure and see datacenters as anchor demand for their energy assets. For gas distributors, datacenter loads represent a new, steady revenue stream that could justify pipeline expansion.
On the other side, wind energy developers and battery storage companies see gas inclusion as a direct threat to their market share. Their concern is concrete: if datacenter operators can meet the Redata’s energy requirements by burning gas (even with “low emission” labeling), the incentive to contract new renewable generation or invest in storage diminishes. For an industry that has built its business case around Brazil’s growing electricity demand, losing the datacenter segment to gas would be a material setback.
What is still undecided
The signing ceremony closed the legislative chapter, but the regulatory chapter is wide open. According to Rafael Dubeux, special advisor to the Finance Minister, the definition of “low carbon” is still under active debate within the government. The Finance Ministry’s position is adversarial: a source involved in the policy design from the start told the eixos news agency that they “will fight to the end to block gas.” The Ministry of Mines and Energy, by contrast, told the same outlet that gas is certain to be included.
The resolution will come through an interministerial portaria that must establish technical parameters. Three scenarios are on the table: full exclusion of natural gas, full inclusion, or conditional inclusion tied to compensation mechanisms such as carbon credit purchases, use of biomethane blending, or carbon capture and storage (CCS) technology. A fourth possibility discussed is limiting gas to backup use only, for instance during grid outages. Until this portaria is published, no datacenter project can know with certainty whether its energy supply strategy qualifies for the tax benefits.
What this means for datacenter operators in practice
For companies planning datacenter investments in Brazil, the Redata offers a dedicated tax regime after roughly eighteen months of legislative uncertainty. The regime was first announced in April 2025 as a provisional measure (medida provisória), which expired without a Senate vote. It returned as a regular bill and was finally approved by the Senate on September 1. Congress also passed PLP 74/2026 on September 3, removing budgetary restrictions that would have prevented the tax incentives from being effectively granted within the 2026 fiscal year.
The practical question for any operator now is energy sourcing. A project powered entirely by wind or solar faces no regulatory risk under the Redata. A project that relies on gas, whether for baseload or backup, faces uncertainty until the interministerial portaria defines the boundaries. Operators in the northeast, where gas infrastructure is more developed but renewable resources are also abundant, face the sharpest version of this trade-off. The regulatory outcome will likely influence site selection, power purchase agreements, and capital allocation decisions for projects that are already in planning stages.
