ANEEL clears 645 MW of Basic Grid access for Casa dos Ventos hydrogen at Pecém

Until now, Casa dos Ventos' green hydrogen project at Pecém had an estimated budget but no authorization to connect to the Basic Grid. Diário do Nordeste records the change and the projection of R$ 25 billion, with the investment not yet formalized.

ANEEL Order No. 4,249/2026, reported by pv magazine Brasil on 11/11/2026, authorizes Pecém VDB 1 to access the Basic Grid at the Pecém III 500 kV Substation, in Caucaia, with contracted demand of 645 MW starting in December 2028. It is the first green hydrogen project with this authorization in the SIN, Brazil's interconnected system. Four other units of the complex, Pecém VDB 2 to 5, await the ONS Permanent Access Opinion.

With the connection point of the first unit defined, two fronts remain open: the formalization of the investment and the ONS opinion on the other four units. The first depends on the company and its partners. The second depends on the operator.

December 2028 now organizes the schedule of the first unit. The grid is no longer its open question. The opinion on the others is the next milestone to watch.
