Key takeaway

A Brazilian court froze grid awards at Replan while the regulator rules on Pahlavan's old contracts.

Pahlavan, a data-centre developer with three projects in the São Paulo town of Paulínia, went to court on 6 October, while Brazil's first grid-access round was still open, to keep the larger capacity its earlier contracts covered. A judge at the Tribunal Regional Federal da 1ª Região (TRF-1, a federal appeals court) gave the regulator, the Agência Nacional de Energia Elétrica (ANEEL), 48 hours to rule on Pahlavan's injunction requests⁠¹.

The order said that until ANEEL ruled, winners of this year's first access season could not be awarded a connection at the Replan substation, where Pahlavan sought its connections, and capacity matching Pahlavan's requests could not be committed. The judge said his order grants no priority, reserves no capacity and authorises no contract. No ANEEL decision had been published by 17 October.

Pahlavan's projects were set up under the access rules that came before the new policy. They already held every paper that system asked for: a ministry ordinance, ANEEL authorisations, access opinions (the grid operator's technical sign-off that a connection is feasible) and signed transmission-use contracts (the agreements to pay for using the grid). Each Paulínia project was to step up from 71 MW to 157 MW of grid use in 2029. The national grid operator, the Operador Nacional do Sistema Elétrico (ONS), found that 86 MW step unviable under the new policy.

The same regulator cleared Scala Data Centers' AI City campus onto the grid in September. The minister promised developers more predictability from the new policy; a developer holding signed contracts under the earlier rules has so far got the reverse.

Deep Analysis

In plain English

Pahlavan is a company building three data centres at Paulínia, near São Paulo. Under Brazil's older grid rules it got signed contracts promising more electricity from 2029. Brazil then changed the rules, and the grid operator said the extra power could not be delivered. Pahlavan went to court. The judge did not take sides. He told Brazil's electricity regulator to decide quickly, and held back some capacity awards until it does.

Deep Analysis

Root Causes

Brazil changed its transmission-access rules while projects authorised under the earlier system still had capacity scheduled to arrive years later. The new policy did not settle what happens to signed contracts whose larger step-ups fall after the switch.

The grid operator's finding that the 86 MW step is unviable reflects physical congestion around Paulínia, home to Petrobras's Replan refinery. A contract can promise capacity the network can no longer deliver once other loads have connected.

What could happen next?

Precedent
The regulator's ruling will show whether contracts signed under the earlier access rules protect future capacity step-ups.
Short term · Assessed
Risk
A ruling for Pahlavan would remove a block of capacity larger than the first round from future competitive allocation.
Medium term · Suggested
Consequence
Other holders of earlier-rule contracts may bring similar injunction requests.
Short term · Suggested

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: Spain cut support for existing renewable plants retroactively in 2013 and 2014, after investors had built under the earlier regime. Foreign investors brought dozens of Energy Charter Treaty claims, and Spain lost the first award, Eiser Infrastructure v Spain, in 2017.

Counter-parallel: Germany's 2014 reform of its Renewable Energy Sources Act cut support for new installations but kept the existing feed-in tariffs for plants already running. Grandfathering kept the change largely out of the courts, at the price of a slower transition.

Across Pahlavan's three Paulínia projects, the disputed step-ups add up to 258 MW, more than the 228 MW the whole first access round allocated. If a court or the regulator restored them, a block larger than the round itself would leave the pool the new policy shares out.

For investors, the immediate cost is delay at Replan, where awards are on hold. The structural cost is a question every lender now asks of Brazilian grid contracts: whether a signed contract secures future capacity or only current use.

Consensus view: The Tribunal Regional Federal da 1ª Região drew its order narrowly: it grants no priority, reserves no capacity and authorises no contract. Courts that frame relief this way usually return the merits to the regulator, so the decisive ruling will come from the Agência Nacional de Energia Elétrica rather than from the bench.

Counter-view: Pahlavan's case rests on Article 5 of Brazil's 1988 Federal Constitution, which bars new law from harming acquired rights or a perfected legal act. A signed transmission-use contract issued under the earlier rules is the kind of instrument that clause protects, which gives the developer a stronger hand than a simple queue position would.

Key tension: Whether a transmission-use contract signed under the earlier rules counts as an acquired right to the 2029 step-up, or only to the 71 MW already in use.

Brazil judge freezes Replan grid awards

A developer holding every permit the old access system asked for is testing in court whether Brazil's new allocation rules can take that capacity away.

Different Perspectives

Nexus Core Systems

Hired FiveNines Group, in a deal announced on 8 October, for early design, feasibility and permit work on a 20 MW AI data centre near Casablanca. It is the first named site of a planned 180 MW programme, still at concept design.

MC Digital Realty

Began building the 24 MW KIX15 data centre in Osaka Prefecture on 7 October, due to open in the fourth quarter of 2028. The joint venture of Digital Realty and Mitsubishi Corporation says it will then run 10 data centres in Japan with about 220 MW of IT capacity.

KT Cloud

Said on 7 October that it and Hyundai Engineering will build a 50 MW AI data centre at Cheongna, Incheon, from the fourth quarter of 2026. Completion is due in the first quarter of 2030, part of KT Cloud's target of more than 1 GW of AI capacity by 2031.

Town of Trebbin

Said on 7 October that work has begun on two data-centre buildings and a substation under building permits already granted. The operating permit under the Federal Immission Control Act is still with Brandenburg's environment agency, so the town postponed its public presentation.

Óscar López, Digital Transformation minister

Said in Madrid on 8 October that he hopes to approve the data-centre royal decree shortly, with urgent processing to reach the cabinet before the 29 November election. He said the final text will take the more than 600 submissions into account, without saying what changes.

Hydro-Québec

Defended its proposed Tarif CD before the Régie de l'énergie du Québec from 1 to 9 October, a rate for data centres of 5 MW or more that adds a premium when peak demand stays below 60% of forecast. Industrial consumers filed their own wording for the clause on who the rate covers.
