How Naturgy compares

Naturgy is NOT the same entity as Red Electrica (Redeia), the separate company that operates Spain's national electricity transmission grid; Naturgy is a comercializadora, not the grid operator. Naturgy is also distinct from Iberdrola and Endesa, the two other large Spanish electricity and gas suppliers it competes against for household customers, and was known as Gas Natural Fenosa before its 2018 rebrand.
