A Contract Test for Macaíba's Wind
Brazil's new data-centre tax law, Redata, asks companies to cover their electricity demand with renewable contracts — measured annually, not hourly. In a Northeast grid that curtailed 20 per cent of its wind and solar potential in 2026, that test proves ownership of clean megawatt-hours, not absorption of stranded ones. The forthcoming decree can require hourly metering data without narrowing the statute's scope.

Three jurisdictions have now worked through that sequence; no other Latin American legal system has.

Sunday Essay · Brazil's Sovereign AI Runs Through the Cell Tower
Brazil's sovereign-AI strategy is being built by a set of overlapping institutional decisions rather than by a chip fab or a frontier model: spectrum obligations attached to 700 MHz licences, a state-cloud intermediation layer at Serpro, Telefônica Brasil's portable OpenShift platform, and a CPQD-led public-services model. The coherence is architectural rather than planned, and the cell tower is its load-bearing unit.
