Solar & Storage

The global energy storage market achieved a significant milestone in 2025, with annual deployments exceeding 100 GW for the first time, signaling a pivotal shift in energy infrastructure worldwide. This surge, detailed in the Volta Foundation's 2025 Battery Report, confirms falling system costs and advancements in long-duration storage as primary drivers. The US continues to emerge as a dominant force in this expansion, with analysts predicting solar, wind, and storage will spearhead the nation's energy sector growth. Read More: PV Magazine, reNEWS.

Domestically, battery storage is not just growing, but strategically adapting to local energy needs and policies. North Carolina, once a leader in solar deployment, is now investigating battery integration to salvage its aging utility-scale solar farms, many of which face obsolescence due to state policy shifts. This pragmatic approach highlights the increasing importance of energy storage in extending the lifespan and viability of existing renewable assets. Read More: Canary Media.

Concurrently, the manufacturing base for solar components within the US continues to solidify, albeit with ongoing legal skirmishes. In South Carolina, a county court rejected a lawsuit attempting to halt the construction of Silfab Solar's crucial 1 GW PV module assembly plant in York County. This ruling clears the path for the C$150 million facility, underpinning efforts to onshore solar supply chains. Meanwhile, GameChange Solar, a Connecticut-based company recognized for its utility-scale solar trackers, has diversified its strategy by launching a new division focused entirely on distributed generation projects across the commercial, industrial, and community solar markets. This move is designed to capture IRA incentives and leverage its domestic supply chain for smaller-scale installations, suggesting a strategic pivot within the manufacturing sector to meet a broader range of solar demand.

Wind Energy

The offshore wind sector faces persistent headwinds, both figurative and literal. In a concerning development for the nascent American industry, Vineyard Wind has alerted courts to potential safety hazards stemming from ten incomplete turbines at its 806 MW Vineyard Wind 1 project. This revelation surfaces just as a court prepares to hear an injunction request against the project, indicating continued legal challenges and operational difficulties. These ongoing issues underscore the complex interplay of project execution, regulatory oversight, and community resistance that define America's offshore wind landscape.

Policy & Markets

In a move that sends shockwaves through humanitarian and environmental circles, the Department of Energy under the Trump Administration has cancelled a foundational solar program intended to bring distributed energy to low-income residents of Puerto Rico. This decision eliminates a critical support system for vulnerable communities still reeling from infrastructure destruction, casting a shadow over the administration's stated energy priorities.

States are increasingly asserting control over energy infrastructure, particularly as demand from new industries like data centers explodes. In Virginia, a state senator is driving legislation to confine future data center construction strictly to industrial zones, aiming to mitigate environmental impacts, escalating energy demand, and community resistance. This bill empowers localities to better manage the siting of these energy-intensive facilities, which are driving up land prices and straining grid capacity. Read More: Virginia Mercury.

Finally, a critical debate is intensifying within the Midcontinent region (MISO) regarding the financial implications of federal energy policy. State utility regulators are scrutinizing the necessity and cost allocation for "emergency" orders issued by the Department of Energy aimed at preventing power plant retirements. These regulators question the reliability benefits of such mandates and demand stakeholder review from FERC on who ultimately bears the cost, revealing a growing tension between federal intervention and regional planning. Read More: Utility Dive.

LOOKING AHEAD

• Virginia Data Center Legislation: Expect heated debate and lobbying efforts around the proposed Virginia bill to restrict data center siting, with significant implications for future development.
• MISO Cost Allocation: FERC's decision regarding cost allocation for DOE's emergency orders in MISO will set a precedent for future interventions into grid operations.
• Vineyard Wind Injunction: The court's ruling on the Vineyard Wind injunction request will determine the immediate future of the contentious offshore project and broader investor confidence.

THE BOTTOM LINE: Local policy battles and federal retrenchment are defining the American clean energy transition this month, even as global battery storage deployments accelerate past unprecedented milestones.
