A live, street-level view of power outages in France.

Open the live map →

International context: Enedis operates most of the public electricity distribution network in mainland France. The application uses French network terminology: HTA means medium voltage and BT means low voltage. The interface is in French because the service covers French outage data; the project documentation is in English.

Enedis publishes current outage information, but affected locations are primarily presented as address labels and are not always easy to understand spatially. This project turns those public reports into an interactive map:

1. Find the communes intersecting the visible map area.
2. Retrieve their current Enedis outage reports.
3. Normalize and deduplicate the affected street names.
4. Geocode those streets and match them to OpenStreetMap geometry.
5. Draw the complete affected street segments with MapLibre GL.

The result is a fast way to answer a simple question: which streets around me are currently reported as affected?

• Street-level visualization rather than isolated address markers.
• Viewport-based loading for every commune visible on the map.
• Progressive results so useful data appears before the entire area finishes loading.
• Incident categories for HTA incidents, planned HTA work, and BT incidents.
• Search and filters synchronized with map selection and street details.
• Mobile-first navigation with a full-screen map and collapsible results sheet.
• Resilient caching that can serve retained data when an upstream service is temporarily unavailable.

             Workers KV cache

External requests pass through provider-specific Durable Objects for
rate budgets, concurrency limits, request coalescing, and timeouts.

The public API only accepts bounded map viewports and returns at most six communes per signed page. Visitors complete one managed Turnstile check, then use a short-lived signed session for progressive requests. This limits scraping and protects both upstream services and operating costs without placing a challenge in front of every page request.

For the complete design, see Architecture and data flow.

Requires Bun 1.3.9.

bun install --frozen-lockfile
cp .dev.vars.example .dev.vars
bun run dev

Open http://127.0.0.1:5173. The example environment uses Cloudflare's official test-only Turnstile keys; never use them in production. Local KV and Durable Object state are stored under .wrangler/.

Deployment requires Wrangler authentication and the Cloudflare resources described in the operations guide.

• API reference — sessions, viewport pagination, response fields, headers, and errors.
• Development guide — local setup, configuration, tests, and repository structure.
• Operations guide — deployment, rollback, observability, and troubleshooting.

• Enedis — public outage reports.
• IGN API Carto — French commune boundaries.
• GeoPF and API Adresse — French address and street geocoding.
• OpenStreetMap via Overpass — street geometry.
• OpenFreeMap — base-map tiles and style.

OpenStreetMap data is available under the ODbL. Individual upstream services remain subject to their own terms and availability.

This is an experimental, unofficial project. It is not affiliated with or endorsed by Enedis and must not be used as an emergency or authoritative network-status service.
