Brazil can reach 7 GW in storage by 2035
Projections from the Energy Research Company (EPE), shared during the Absolar Storage Leaders event, depend on a stable legal framework and regulatory progress. Authorities and stakeholders in the electricity sector highlight the role of batteries in reducing costs, ensuring energy security, and expanding renewable energy.
Europe: AccelerateEU supports a 200 GW storage target, but omits financing mechanism
The European Commission’s AccelerateEU energy crisis plan endorses a 200 GW battery storage target for 2030 but proposes no dedicated financing mechanism to reach it, according to SolarPower Europe (SPE), which is calling for a separate EU-wide auction funded by emissions trading revenues.
Germany may curtail preferential treatment of large battery storage facilities near substations
The recently introduced preferential treatment for large battery storage facilities within a 200-meter radius of substations may soon be scaled back under the next amendment to the building code. At a minimum, lawmakers are considering tightening the eligible zone by introducing a minimum setback of 100 meters, effectively limiting the preferential treatment to projects located within a narrower band of 100 to 200 meters around substations.
Long-duration battery storage can contribute to security of supply more cost-effectively than gas-fired power plants, LCP Delta finds
LCP Delta has conducted a study analyzing the potential contribution of long-duration battery storage to security of supply within capacity tenders in Germany, including an economic comparison with gas-fired power plants and the resulting costs to the public. However, the authors explicitly note that they are not advocating for a complete phase-out of new gas-fired power plants.
