AI Data Center Power Tracker

A public, sourced map of the largest AI data center projects in the world: where they are being built, how much power they need, and where that power comes from.

AI is turning data centers into some of the largest new electricity loads on the grid. The facts about each project are scattered across press releases, utility filings and local news. This tracker collects them in one place and links every number to its source.

Live site: https://avishagminnes.github.io/ai-dc-power-tracker/

What it shows

• Map of every project, sized by planned power and coloured by status (announced, under construction, operating).
• Summary figures: planned gigawatts, how much is already being built or running, and how many projects plan their own on-site power.
• Charts of planned power by power source (grid, natural gas, nuclear, solar…) and by country.
• Searchable table with filters, project details, sources, and CSV/JSON download.
• Changelog of every addition and change, so readers can see what is new.

How the data is collected

1. Once a week, the /update-tracker Claude Code skill (.claude/skills/update-tracker/SKILL.md) searches recent news, company announcements and utility filings for new projects and status changes.
2. It records only facts confirmed in a source it opened, following the rules in CLAUDE.md. Unknown values stay empty, never estimated.
3. scripts/validate.mjs checks every record (required fields, allowed values, coordinates, dates, at least one source per project), and with --check-links it finds dead source links.
4. Every change is logged in data/changelog.json and shown on the site.

Data

• data/projects.json: one record per project. The format is described in CLAUDE.md.
• data/changelog.json: every change, newest first.

Planned power is the full-build figure announced by the developer. Some sources give total facility power and others IT load; each record says which. Locations are approximate unless the exact site is public.
