28-A Blackout Timeline

A timeline of the April 28, 2025 Iberian Peninsula blackout, built from the official post-mortem.

Archived — built for the moment, not maintained.

When the Spanish Government published its official report on the blackout that hit Spain and Portugal, it landed as a dense technical PDF — thorough, but not something you’d hand a curious reader. ENTSO-E, Europe’s grid operator association, published its own independent analysis around the same time. I pulled the event sequence out of both and turned it into a timeline you can actually scroll through.

What it does

  • Chronological timeline of the events that led to and followed the blackout, sourced from the official report
  • Spanish and English, light and dark mode
  • Statically pre-rendered for a fast, zero-loading-state first view

How it’s built

React 19 + TypeScript, MUI, i18next, and SWR, statically pre-rendered with vite-react-ssg so Spanish content is fully indexable out of the box.

  • SEO-first SSG — the app ships pre-rendered HTML with JSON-LD structured data (WebSite, Event, BreadcrumbList schemas), hreflang alternates, and an auto-updated sitemap
  • Full i18n — Spanish and English throughout, with SSR-safe guards so language and theme never break the static build
