Spain Self-Consumption Compensation (Excedentes)
Administered by Ministerio para la Transición Ecológica y el Reto Demográfico
About this program
Under Royal Decree 244/2019, Spanish households and businesses with solar self-consumption installations can receive financial compensation for surplus electricity exported to the grid. The compensation is applied as a credit on the electricity bill, offsetting the variable energy charges (but not fixed charges or taxes). The scheme supports both individual and collective (shared) self-consumption configurations, allowing apartment buildings and neighbouring properties to share a single solar installation. Spain's self-consumption regulations were significantly simplified in 2018-2019 after the repeal of the controversial 'sun tax' (impuesto al sol), making distributed solar economically viable.
Eligibility requirements
- Must have a grid-connected solar self-consumption installation
- System must be registered with the regional autonomous community
- Available for installations up to 100 kW for simplified compensation
- Must have a digital meter capable of recording bidirectional energy flow
- Surplus energy compensated at wholesale market price (monthly average)
- Compensation credited against variable energy charges on the electricity bill
- Cannot earn net income (compensation cannot exceed energy consumption charges)
- Collective self-consumption available for shared installations within 500m (2km in some regions)
