The 16 January 2026 Resolution revises the valley tariff period consumption requirement for high-consumption customer classification, setting that at least 46% of energy must be consumed during such a period in at least two of the three preceding years (Art. 3.2.b of Royal Decree 1106/2020). This requirement applies as a condition for access to the category, following a temporary suspension during the cost adjustment mechanism established in Royal Decree-Law 10/2022 (transitional provision four).
Electricity consumers who wish to apply for the high-energy-consumption category must verify their consumption during the valley tariff period, as it is now required that at least 46% of their annual consumption takes place during this period across two out of the three previous years. Businesses and individuals with high energy demand should review their consumption records to meet the new threshold. Energy advisors should update their recommendations and verification procedures for customers applying for this category.
