Tariff launch and price level

As ad hoc news reported on September 18, 2026, Endesa launched new free-market electricity tariffs that offer customers a stable energy price for 3 or 5 years through its Luz 24h a 3 anos and Luz 24h a 5 anos products. The same report said the stock opened at EUR 43.49 on September 18, 2026 and moved close to its recent high of EUR 43.72.

That pricing structure gives households and small businesses longer visibility than the previous one-year fixed-price standard, a detail that matters because the stock was already trading only EUR 0.23 below its 52-week high on September 17, 2026. The market snapshot on September 18, 2026 also showed 8,028 shares traded in the opening move.
