Solar power in sunny weeks, wind power in overcast weeks and hydro power in rainy weeks means electricity costs in Portugal and Spain have been incredibly low over the last year.
Newspapers here have been running articles saying the way the market works will make further investment and maintenance difficult because power generators are barely being paid.
