About this market
Spain and Portugal form the MIBEL market and clear at the same price most of the time. Weak interconnection with France, around 3 percent of peak demand, frequently decouples the Iberian peninsula from the rest of Europe, so Spanish prices can sit far below or far above the continental level.
