Renewable Energy Weekly — 2026-09-14
Global renewable energy investment continues to accelerate, with BloombergNEF reporting $327.5bn invested in the first half of 2026, driven by a record $25bn into co-located solar and storage. In the US, the SunZia project, touted as the largest in history, is now fully operational, delivering more power than the Hoover Dam. Meanwhile, Latvia’s Latvenergo is expanding its Baltic battery storage and solar push alongside wind acquisitions.

Top Stories
SunZia Wind Project Fully Operational
- What happened: The SunZia Wind project in New Mexico, developed by Pattern Energy Group, has come online. It is described as the largest renewable energy project in US history.
- Why it matters: This milestone marks a significant achievement for the US energy transition, demonstrating the viability of massive-scale wind and transmission infrastructure. The project exports power to Arizona and California, enhancing grid reliability in the Southwest.
- Scale: 3,500 MW capacity (3,650 MW mentioned in some reports, but "largest" context confirms high GW scale), $11 billion investment.

US Deploys 19.2 GW of Solar in H1 2026
- What happened: The US deployed 19.2 GW of new utility-scale solar capacity in the first half of 2026. Q2 alone saw 11.4 GW installed.
- Why it matters: Despite growth constraints, the US remains on track to install a record 86,000 MW of new utility-scale electric generating capacity in 2026, with 93% from solar, wind, and storage. Solar is predicted to account for 51% of this new capacity.
- Scale: 19.2 GW added in H1; projected 86 GW total new capacity for 2026.
