Battery Adoption Grows, But Spain’s Self-Consumption Expansion Slows

Spain added 327 MWh of new battery storage for self-consumption in 2024, a 34% slowdown from 2023. However, 26% of new residential installations now include batteries (110 MWh), with cumulative capacity hitting 2.2 GWh.

Key Trends:

✔️ Business demand rising: Companies seek lower energy costs and market price insulation.

✔️ Regulatory advances: New laws expanded collective self-consumption and surplus energy compensation.

✔️ Industry demands: UNEF urges tariff reforms, faster permits (up to 500 kW), and clearer storage rules.

Declining Solar-Only Installations:

Residential: ▼14% (Q1 2025)
Commercial: ▼17%
Industrial: ▼20%
Next Steps: Spain must simplify regulations and incentivize storage to revive growth.
