US Solar and Battery Storage Surge Continues Amid Policy Uncertainty
Utility-scale solar leads electricity generation growth in 2025, expanding by 33% over 2024, with new solar projects making up more than half of the year’s added capacity; battery storage is also booming, with 10 GW deployed across the Midwest and central US, enough to power 9.4 million homes and save $25 billion in energy costs[4][3]. However, the US is rapidly curtailing renewable subsidies and increasing trade barriers, raising concerns about the pace of future wind and solar development after 2026[1].
Renewables Hit Record Grid Share, With 77.9% in Some Regions
Renewable energy reached a record 77.9% share of electricity generation in key US markets this week, driven by the rapid expansion of solar and wind and strong grid integration efforts[5]. This milestone highlights the accelerating transition away from fossil fuels, particularly as natural gas generation declines due to high fuel prices and increased competition from renewables[4].
Data Center and Cleantech Demand Drive New Grid Modernization Initiatives
Soaring electricity demand from data centers, AI, and cleantech manufacturing is outpacing supply, prompting new investments in grid infrastructure and renewables to bridge a projected 57 GW resource gap by 2030[2]. Utilities are responding by repurposing brownfield sites for new capacity and accelerating the deployment of advanced storage and grid modernization technologies[2].
Major US Solar Policy Changes Take Effect, Including New ITC Guidance and Net Metering Battles
September 2025 sees significant US solar policy shifts, including updated IRS guidance on the Investment Tax Credit (ITC), the imposition of new tariffs, and contentious state-level debates over net metering and storage incentives[10]. These regulatory changes are creating both challenges and opportunities for solar developers and consumers this fall[10].
Australia Approves 100th Renewable Energy Project Under Labor Government
The Australian government announced approval of its 100th renewable energy project since 2022, marking a major milestone in national efforts to accelerate clean energy deployment and grid decarbonization[7]. This achievement underscores Australia’s ongoing commitment to renewable energy expansion and regulatory streamlining for project approvals
