Solar & Storage

The clean energy market is navigating a complex landscape of policy uncertainty and robust private investment. Today, Jupiter Power, a significant U.S. battery energy storage system developer, announced it secured a substantial $500 million corporate credit facility. This funding directly supports the accelerated development of its battery storage projects across the nation, an essential move to stabilize a grid increasingly reliant on intermittent renewables.

This infusion of capital for grid-scale storage comes as another battery player, Redwood Energy, closed its Series E financing round, raising $425 million with notable participation from Google. Redwood plans to use these funds to dramatically expand its U.S. energy storage recycling division, a crucial step towards building a more circular and resilient domestic supply chain for batteries.

Despite this surge in storage investment, solar project economics face headwinds. North American solar Power Purchase Agreement (PPA) prices increased for the second consecutive quarter in Q4 2025. This rise is attributed to ongoing policy changes, a shifting tax credit landscape, continued tariff uncertainties, and persistent permitting hurdles. While wind PPA prices saw a slight decrease, the upward trend in solar PPAs adds a layer of uncertainty for developers like Primergy Solar and Avantus, potentially compressing margins.

On the residential and community solar front, California, Florida, and Texas are seeing expansion from U.S. startup Terra Energy, which offers subscription-based rooftop solar panel services aiming for up to 50% savings on electricity bills. This model could unlock new markets by lowering the upfront cost barrier for homeowners. Concurrently, solar streetlight provider Streetleaf has partnered with homebuilder Lennar Homes for a national rollout of its off-grid LED streetlights in new community developments. This collaboration highlights the growing integration of distributed solar solutions into new infrastructure. Read More: CleanTechnica, PV Magazine USA.

These grassroots solar efforts gain traction amidst a multi-state legislative push for plug-in solar. Legislation allowing plug-in solar devices up to 1,200 watts without utility permission has been introduced in at least 24 U.S. states. Advocates for California's "Plug Into the Sun Act" hope to replicate Utah's success and spur nationwide market growth, potentially boosting U.S. solar manufacturing. This movement could be significant for companies catering to residential and small commercial sectors. Read More: PV Magazine USA.

Wind Energy

The Trump administration has restarted a critical permitting process directly impacting the development of utility-scale wind farms within the United States. This move, reported by , signals an attempt to reassert federal control over renewable energy project procedures, contrasting with judicial decisions that have challenged the administration's prior efforts to slow clean energy. This development follows a federal judge’s recent decision to overturn the administration's stop-work order on the Vineyard Wind project in Massachusetts, highlighting a contentious push-and-pull over wind development even as federal policy signals mixed messages. Developers like Atlantic Power and Invenergy must closely monitor these evolving federal procedures. Read More: Heatmap News.

Policy & Markets

A federal judge delivered a significant legal setback to the Trump administration's agenda by ruling that a Department of Energy (DOE) panel formed to question established climate science was unlawful. This panel's report had been a linchpin in the administration's initiative to roll back regulations on climate pollution. The ruling, reported by the , directly challenges the legal underpinnings of the administration's current environmental policy stance, casting doubt on the legitimacy of future deregulation efforts. Politico further notes the "awkward situation" this creates for President Trump, whose past actions on environmental regulations are under scrutiny as he campaigns on deregulation.

This judicial intervention underscores the deep divisions and legal battles defining clean energy policy in 2026. Simultaneously, grid operators are grappling with strain exacerbated by increasing demand. PJM, a major U.S. grid operator, is now considering enlisting backup generation from data centers and other large energy consumers to avert blackouts during extreme weather. This pragmatic move highlights the immediate challenges of grid reliability and the growing role of large loads in grid management. Read More: Utility Dive.

Interconnection reform remains a critical bottleneck. New Hampshire is attempting to streamline its outdated solar interconnection procedures, which have severely hampered solar deployment, with the ambition of creating a nationwide model. This initiative seeks to address regulatory roadblocks that have made connecting solar projects to the grid more difficult than in neighboring states, and could provide a blueprint for other states like Texas and California struggling with grid queue backlogs.

Globally, China's polysilicon output is expected to drop by 15% in January due to production cuts. This will impact wafer prices, which are falling, though cell and module prices remain stable. While this primarily affects the global supply chain, U.S. developers relying on imported modules or components need to monitor these shifts closely, especially given ongoing tariff and trade policy uncertainties. Read More: PV Magazine.

LOOKING AHEAD

• Federal Climate Policy: Expect further legal challenges to the Trump administration's environmental deregulation efforts following today's DOE panel ruling.
• Interconnection Reform: Watch New Hampshire's efforts closely as it attempts to establish a replicable model for nationwide solar interconnection reform.
• Solar PPA Volatility: Monitor Q1 2026 solar PPA pricing for continued upward trends, signaling sustained market pressure from policy and supply chain factors.

THE BOTTOM LINE: Legal pushback on federal deregulation coupled with rising solar PPA costs signals a challenging, yet highly capitalized, U.S. clean energy market demanding increased agility from developers and investors.
