In Italy, the day-ahead electricity market follows the rule of marginal price, over six physical zones.
Network congestion can produce different prices in different zones, i.e. the market splitting. This means that energy can have different value in the Nation.
By design, it was decided that consumer should pay the electricity at the same price wherever in Italy. This price is the PUN: Prezzo Unico Nazionale that means National Unique Price.
