Thirty-five thousand generating stations on a globe you can spin, sized by what they produce and coloured by what they burn. Filter to hydro and the world’s steep rivers appear; filter to a gigawatt and see how little is left.
Turn everything off but hydro. The Rhine, the Yangtze, the Parana and the Western Ghats appear as lines of light — because a hydro station needs falling water, and falling water follows terrain.
The Koyna chain shows up clearly on the Sahyadri scarp.
Fewer than two hundred worldwide, against ten thousand solar farms — yet the nuclear circles are bigger, because a single reactor site carries what hundreds of solar farms do.
Drag the size filter up to 1 GW and watch what is left standing.
Solar is the most numerous fuel in the database and barely existed at utility scale when many of these plants were built. Rajasthan, Gujarat, the Mojave and Xinjiang are the obvious places it landed.
Circles are sized by the square root of capacity, so the area you see is proportional to the megawatts.
What this is, and what it is not. The data is the World Resources Institute’s Global Power Plant Database, under CC BY 4.0 — 34,936 stations and 5,707 GW, every one with a checked position. It is a snapshot rather than a live feed, and it under-counts small and recent plants everywhere: rooftop solar is absent by design, and a station commissioned since the last release will not be here. Capacity is nameplate, meaning what a station can produce flat out, which is a very different number from what it actually produces — a coal station runs most of the year and a solar farm about a fifth of it, so comparing two circles compares what they could do rather than what they did.
Older Indian survey and revenue records sit on the Everest spheroid, not WGS 84. Treating one as the other puts everything a few hundred metres out — enough to move a plot boundary onto a neighbour.
Kalianpur 1880, 1937 and 1975, the India zone grids, UTM zones 42N to 47N on both WGS 84 and Indian datums, and the WGS 84 state systems.
Paste a column straight out of a spreadsheet. Anything after the first two values is carried through as a label, and the result downloads as CSV.
The arithmetic runs in your browser with proj4. No coordinate is transmitted, logged or stored anywhere.
WGS 84 and Web Mercator, UTM zones 42N to 47N on both WGS 84 and Indian datums, the Kalianpur India zone grids, and the WGS 84 state systems including Maharashtra. Each is listed with its EPSG code so you can check it against your source.
Transformations use the standard seven-parameter shifts published for each datum. Between Everest-based Indian datums and WGS 84 the difference is a few hundred metres, so using the wrong one is immediately obvious on the map preview.
Yes. Switch to the bulk tab and paste a column. Comma, tab, semicolon or space separated all work, and anything after the first two values is kept as a label. Download the result as CSV.
Easting or longitude on the left, northing or latitude on the right. The labels change with the system you pick, so you never have to remember. Bulk mode has a swap option.
No. Everything runs in your browser using proj4, so no coordinate ever leaves your device.
Free, no sign-up, no file size limit — and your data never leaves your machine.
