The Short Version
The claim is rooted in a real April 2010 incident in which Venezuela's state electricity company, Corpoelec, blamed an iguana for a power outage in Anzoátegui — but it overstates both the certainty and the scope. No independent source verified the iguana as the actual cause; the attribution is widely characterized as political scapegoating for systemic grid failures. The documented outage affected "10 sectors," not the entire state, making the unqualified phrasing materially misleading.
