Top Stories
South Africa Opens R161.2 Billion Renewable Energy Investment Pipeline
- What happened: South Africa's renewable energy sector is attracting approximately R161.2 billion (roughly USD 8.7 billion) in investment commitments through 2030, driven by private power purchase agreements (PPAs), solar and wind projects, and energy storage systems.
- Why it matters: This marks a significant shift toward private-sector renewable energy development in South Africa, addressing energy security challenges and positioning the country as a major renewable energy hub in Africa. The investment wave reflects growing global confidence in solar and storage economics.
- Scale: R161.2 billion investment through 2030 across multiple technology types
IEA Reports Record 108 GW of Global Battery Storage Additions in 2025
- What happened: The International Energy Agency (IEA) released data showing a record 108 GW of battery energy storage system (BESS) additions globally in 2025, marking a massive acceleration in energy storage deployment.
- Why it matters: Battery storage is becoming critical to grid stability as solar and wind capacity expands. This milestone demonstrates that storage is no longer a bottleneck for renewable energy integration and confirms economics favor large-scale deployment.
- Scale: 108 GW of new battery storage capacity added in 2025 globally
US Q1 2026: Solar and Storage Lead Clean Power Additions with 6.4 GW
- What happened: The US added 6.4 GW of utility-scale solar, wind, and storage capacity in Q1 2026, with solar and battery storage accounting for more than 90% of new clean power additions. Wind capacity in the pipeline remained stagnant at 28 GW, while offshore wind declined 33.3% to 10 GW.
- Why it matters: This data shows a decisive shift away from wind toward faster-to-deploy solar and storage technologies. Many projects remain under construction and are expected to reach commercial operation dates (COD) later in 2026, potentially driving another wave of capacity additions.
- Scale: 6.4 GW added in Q1 2026; solar and storage comprise >90% of additions
