In parallel, the liquidation of renewables, cogeneration and waste amounted to 4,431 million euros, of which the majority was financed from the electrical system and a small part through the General State Budgets.
On the other hand, the CNMC also published the second liquidation of the electrical system corresponding to February, which reflected a much larger temporary deficit, of 909.37 million euros. In that month, revenues were 1,453 million compared to costs of 2,362 million, leaving the coverage ratio at just 57.15%.
Regarding the gas sector, the fifth settlement corresponding to the period between October 2025 and February 2026 showed an increase in income of 10.5%, up to 896 million euros. Gas demand grew 7% year-on-year, driven especially by large consumers and some domestic segments.
