State of the Nordic Power System (Click 'Table' for more information): http://driftsdata.statnett.no/Web/map/snpscustom http://driftsdata.statnett.no/Web/map/snpscustom The data seem to be a few minutes old, and doesn't have history (which would be nice).

It's interesting to see all the export/import flows, like exporting to Germany yet importing from DenmRk. I guess it's due to price sifferences?

  The imports and export are changing all the time, depending on the production or demand of each country, to keep the production and consumption in balance. It's sometimes easier/faster to import power when you need it (when there is a demand spike) than start your own generators to match the demand with internal production. Then when the other country has a demand spike, you pay them back with your production. In many cases no actual money change hands, these are kept as "power debts" that will be paid later. It can also be easier/cheaper to import power for one point near the border than transport it from farther production facilities.

  The price differences are less important there rather than the total system balance - locations of supply and demand, and the exact current amount of supply and demand at each location at each moment. In a connected power system, if power 'needs' to get from A to B, it won't only flow through the direct connection, but along the longer loops as well, which often creates 'transit'. For example, in that map from NO5 to SE5 through Denmark, and from NO1 to NO3 through Sweden. This is normal and pretty much unavoidable - it's more efficient to optimize the flows to reduce total system losses, and then just try to bill everyone fairly. You can't simply set a specific flow amount (well, you can force it to 0) to some country and keeep it there without mucking up the rest of the system, unless high voltage DC links are used to connect separate power systems.
