Norway (where I'm from) is somewhat complex, because the country is divided into five regions, and the northernmost regions have poor transfer capability to the southern regions.

The southern regions, however, have quite good transfer capacity to export (to European countries), so those regions often have to compete with export prices.

What this means, is that the prices can vary significantly withing Norway. While we up in northern Norway paid around $0.0005 / kWh last summer, my relatives south paid something like $0.3-$0.4 / kWh. It's been a pretty big deal for the past years.

Our energy production is almost purely hydro, with wind and solar as very distant second and third source. All our LNG is more or less sold off to Europe.
