How Iberdrola compares

Iberdrola is NOT the same entity as Red Electrica (Redeia), the separate company that operates Spain's national electricity transmission grid; Iberdrola is a comercializadora and generator, not the grid operator. Iberdrola is also distinct from Endesa, which is majority owned by Italy's Enel group, and from Naturgy, a separate Spanish electricity and gas supplier, both of which compete directly with Iberdrola for household customers.
