svk.se (Swedish grid operator) is listing current statistics for energy production and has the category 'Not Specified':
> Unspecified production includes, for example, gas power, wave power and braking power. Production from plants with more than one production type and where these can not be separated is also included in this category.
Braking power refers to regenerative braking, energy that's put back on the grid from the electric trains. Presumably from the iron ore trains from up north.
Unfortunately it does not list exactly how much of the 'Not Specified' is from braking power alone. Generation in this category as we speak is 589 MW.
