The Nordic Grid Screensaver

The Nordic Grid screensaver shows live production and consumption for each country in the interconnected Nordic power system — Norway, Sweden, Finland and Denmark, with the Baltic states attached — in megawatts. It runs in the browser with nothing to install; press ESC to exit.

How the The Nordic Grid screensaver works

The saver reads Statnett's operational data feed, refreshed through this site's pipeline.

No account and no key: the request goes straight from your browser, or from this site's own refreshed copy of the feed where the source does not permit browser access.

Values are drawn on a canvas that resizes with the window, so it works on a laptop or a wall display.

If the source is unreachable the saver says so on screen rather than showing stale numbers as though they were current.

A worked example

Each country appears twice, once for production and once for consumption, with bars scaled against the largest figure. Norway's production is almost entirely hydro, Sweden's is hydro and nuclear, and Denmark's swings with the wind. Statnett returns each series as a positional array with country labels held separately, so the pipeline zips the two together — read either alone and the numbers belong to nobody.

Settings & tips

Frequently asked questions

Why are these countries treated as one system?
Because they are synchronously interconnected and trade continuously through a shared day-ahead market. Electrically and commercially the Nordic region behaves much more like one grid than four.
Why does production not match consumption?
Because the difference flows across borders. A country producing more than it consumes is exporting the surplus, and the net exchange figures in the same feed account for it.
Is this real data?
Yes. It comes from Statnett's operational data feed, refreshed through this site's pipeline. Nothing is invented or simulated, and if the source cannot be reached the saver reports that instead of drawing something plausible.
Does it cost anything or need an account?
No. Every screensaver here is free, runs in the browser and needs no sign-up. This one uses a public API that requires no key.
