Solar & Storage
The Ohio Power Siting Board's request to the state Supreme Court amounts to a legal punt on one of the most closely watched solar permitting cases in the Midwest. Vesper Energy had appealed after the board denied a permit for a utility-scale solar project, and a ruling could have established binding precedent on how weighs local opposition against state energy policy when siting large arrays. Instead, the board wants the case tossed — leaving the current ad hoc permitting framework intact and developers guessing about which projects will survive the approval process. Read More: Ohio.
That legal limbo matters because the factual basis for blocking Ohio solar keeps getting thinner. A separate published today found solar installations occupy less than 0.17% of the state's prime farmland, a figure that undercuts the agricultural-loss argument central to most local opposition campaigns. The Frasier Solar project drew particular scrutiny, but even with it and every other permitted array included, the footprint is a statistical rounding error on Ohio's roughly 14 million acres of farmland. For developers with Ohio pipelines, the takeaway is that project risk in the state remains more political than empirical. Read More: Ohio Capital Journal analysis.
In California, the financing picture looks considerably clearer. Avantus closed $525 million in construction debt for Aratina 2, a utility-scale solar-plus-storage project that ranks among the largest single-asset clean energy financings of 2026 so far, according to. The deal signals continued lender appetite for paired solar-storage assets in California, where the state's aggressive procurement mandates and CAISO's duck-curve pricing dynamics make storage economics more bankable than in most other markets.

The storage pipeline is also diversifying beyond lithium-ion. Frontier Power USA selected four sites for 920 MWh of battery capacity using Eos zinc hybrid-cathode chemistry, manufactured domestically by Stella Energy Solutions. That follows yesterday's news that Peak Energy raised $80 million for a sodium-ion battery plant in Sacramento. Three other U.S. firms — Peak Energy, ESS Inc, and Unigrid — are pushing sodium-ion technology toward commercial deployment in both U.S. and European markets. Zinc and sodium chemistries avoid the lithium supply-chain risks and China dependencies that have dogged the dominant battery technology, a selling point that resonates with both the Trump administration's domestic-manufacturing emphasis and investors pricing in geopolitical risk.

Sunrun, meanwhile, is testing whether rooftop solar and home batteries can do more than feed the grid. The company launched a that uses its residential solar-plus-storage fleet for edge computing — essentially turning customer homes into tiny data centers. It is an early-stage bet, but if the economics hold, it could open a new revenue stream for residential solar operators competing against falling panel prices.

Wind Energy
ComEd's commissioning of two 345 kV substations in central Illinois is the kind of unglamorous grid work that determines whether wind projects actually get built. The substations in LaSalle and Woodford Counties of new wind capacity in a region where generation has outpaced transmission for years. With MISO's interconnection queue still measured in years for most applicants, dedicated substation builds that shortcut the bottleneck give wind developers in the Illinois wind corridor a concrete path to energization.

Internationally, Vestas acquired the 272 MW St Patricks Plains wind farm in Tasmania, with construction targeted for 2027. The deal does not directly affect U.S. markets but shows the Danish manufacturer doubling down on project ownership rather than just turbine sales — a business-model shift that U.S. wind developers and offtakers should track as Vestas competes for American projects.
Policy & Markets
Data centers are triggering a zoning revolt across multiple states. A Maryland county imposed a flat two-year moratorium on new data center construction, citing concerns that surging AI-driven electricity demand would raise rates for existing ratepayers and strain grid capacity. In , a county is after a property owner withdrew support for an AI data center proposal, while Michigan's Garfield Township planning commission recommended allowing zoning moratoriums in response to environmental and water-consumption concerns.

The pattern is now visible in at least three states simultaneously, and it matters for clean energy developers on both sides of the equation. Data centers have been the single largest driver of new corporate renewable energy procurement over the past 18 months. If local moratoriums slow their construction, offtake agreements for wind and solar projects could stall in tandem. But the moratoriums also reflect a real grid-capacity crunch — one that makes the case for accelerating both generation and transmission buildout.
On the federal front, the Trump administration's nuclear energy push is gaining definition. The that the administration's plans to advance nuclear power are moving forward, aided by recent technological developments that have made deployment targets more realistic. Nuclear remains the one clean energy technology with broad bipartisan support in Washington, and the administration has positioned it as a complement to — rather than a competitor with — natural gas in meeting baseload demand growth. For renewable energy developers, the practical question is whether nuclear funding draws from the same federal pot as clean energy incentives or expands the overall spending envelope.

LOOKING AHEAD
- Ohio Supreme Court Solar Decision: Whether the court grants the Ohio Power Siting Board's dismissal request or proceeds to rule on Vesper Energy's appeal will shape the permitting outlook for every utility-scale solar project in the state's pipeline.
- Data Center Moratorium Contagion: Watch for additional counties and townships — particularly in Virginia's data center corridor and Texas's ERCOT zone — to consider similar pauses as the Maryland, Montana, and Michigan actions draw national attention.
- Non-Lithium Battery Deployment Timelines: With Frontier Power's 920 MWh zinc project and Peak Energy's sodium-ion plant both advancing, the next milestone is firm construction start dates and utility offtake contracts that prove these chemistries can compete on delivered cost.
TODAY'S QUICK ANSWERS
Q: What does the Ohio siting board's legal maneuver mean for solar developers with Midwest pipelines?
A: It preserves uncertainty. Without a Supreme Court ruling, Ohio's utility-scale solar permitting process remains vulnerable to case-by-case political decisions rather than clear legal standards. Developers with active Ohio applications — and there are several gigawatts in the queue — should budget for longer timelines and more aggressive local opposition campaigns, since opponents now know the state won't face a precedent that constrains their objections.
Q: Why should clean energy investors pay attention to county-level data center moratoriums?
A: Data centers are behind the largest corporate renewable PPA volumes in the country right now. If moratoriums in Maryland, Montana, and Michigan spread to high-growth data center markets, the downstream effect hits solar and wind offtake — fewer data centers mean fewer long-term power contracts. Conversely, moratoriums driven by grid-capacity concerns strengthen the argument for new generation and transmission investment, potentially accelerating utility-scale procurement in adjacent regions.
Q: Can zinc and sodium-ion batteries realistically compete with lithium-ion at grid scale?
A: They're not trying to beat lithium-ion on every metric — they're targeting the niches where lithium struggles. Zinc and sodium chemistries offer longer duration, fewer supply-chain risks, and domestic manufacturing advantages. The 920 MWh Frontier Power deployment and Peak Energy's $80 million factory raise will produce the first real-world cost and performance data at meaningful scale, which is exactly what utility procurement teams need before they'll shift purchase orders.
THE BOTTOM LINE: Ohio's attempt to sidestep a landmark solar ruling, combined with data center moratoriums proliferating in three states, shows that local permitting and siting politics — not federal policy — remain the binding constraint on how fast clean energy actually gets built.
