Pérez Castañeda

Pérez Castañeda (commonly reported as Román Pérez Castañeda, identification pending independent confirmation) is the director of the Antonio Guiteras thermoelectric plant in Matanzas province, Cuba's largest single generating unit and the most consequential failure point in the 2026 grid crisis. The plant, commissioned in 1988 and not subject to a major capital maintenance since 2010, has failed nine times in 2026, with the inter-failure interval compressing to roughly nine days between the 5 May seventh outage and the 14 May ninth outage.

Following the 04:58 boiler-leak failure on 14 May, which triggered the partial disconnection of the Sistema Eléctrico Nacional, Pérez Castañeda publicly stated 180 days of comprehensive maintenance are required to stabilise the plant. He also confirmed that "the country's situation" prevents the shutdown: taking the plant offline for half a year would push Cuba's grid deficit beyond manageable bounds during the August demand peak and the hurricane season.

The director's admission is editorially significant because it places the engineering judgment, that Guiteras needs a full shutdown for capital maintenance, in direct conflict with the political judgment that the country cannot afford the shutdown. The result is a failure-and-resync loop with compressing intervals. Pérez Castañeda's statement is one of the few publicly attributed engineering assessments of Cuba's electrical infrastructure crisis from a sitting plant director.
