wtf is gb-power-dashboard?

The GB Power Dashboard is a single-page web app that shows real, up to date information about the Great Britain electricity market, built to look and feel like a professional commodity trading terminal. It pulls only public data through an automated pipeline and shows it live, updated daily, without any styling that hides how much of what you see is measured fact versus estimate. Every number the app displays is labeled either as an observed reading from a real data source or as an estimate, so nothing pretends to be more certain than it is. You can view the finished dashboard through a hosted link with nothing to install, or you can run your own copy locally. Running your own copy means cloning the repository, running a single Python script that builds the full dataset and every other output the dashboard needs, then serving the app folder with a simple local web server and opening it in a browser. The setup only needs Python 3.10 or newer and one small library called certifi. The app itself is plain HTML, CSS, and JavaScript with a bundled charting library, so there is no build step and no other dependencies to install. One feature works differently from the rest: an optional overnight summary panel written by Claude, Anthropic's AI coding assistant, using the day's published data. This is switched off by default and only turns on if you explicitly set a flag in your local configuration, and it draws on your own Claude subscription rather than a separate paid API key. Running it daily costs a small, measured amount each month. Everything else in the dashboard, including a year of market data, price and generation charts, and coverage of seven European market zones, needs no subscription or account of any kind and uses only free, public data sources. This project would suit energy analysts, students of power markets, or anyone curious about how electricity is priced and generated in Great Britain who wants a transparent, always up to date reference rather than a one time report. The data comes from sources like the Elexon Insights API, the ENTSO-E Transparency Platform, and other public UK energy data portals, each documented with its update frequency and licensing terms.
