Brazil approves first co-located solar and battery project

Why it matters: Aneel’s decision lets Brazil’s first 5 MWh solar‑storage system serve utilities, shaving peak‑hour costs by up to 10%.
- Aneel grants approval for a 5 MWh battery co‑located with a solar farm, setting a first‑ever regulatory precedent in Brazil.
- Solar‑Battery Project will be the country’s inaugural integrated storage system, enabling dispatchable solar power during peak demand.
- Brazilian utilities can now reference this model to add storage to existing solar assets, potentially lowering operating costs.
Brazil’s energy regulator Aneel has approved the nation’s first solar plant paired with a 5 MWh battery, establishing a regulatory template for co‑located storage and accelerating the country’s renewable rollout.
