Solar & Storage
The Midwest keeps stacking utility-scale solar capacity. One day after the Ohio Power Siting Board's permit approval made headlines, developer Savion's Oak Run Solar project — 800 MW of solar paired with 300 MW of battery storage in Madison County — now has a clear path to construction after a protracted legal fight. The project, which will be Ohio's largest solar installation, includes an agrivoltaics component and will deliver power into the PJM Interconnection grid. For developers watching PJM's congested queue, the permit signals that large-scale solar-plus-storage can still survive local opposition in a state where energy prices have surged 34% since 2022, as Solar Builder reported.

Across the state line, NorthStar Clean Energy wrapped construction on a 120 MW solar plant in Oceana County, Michigan. And in Illinois, PureSky Energy brought its McLean 1 Community Solar project online — the company's first Illinois installation — dedicated entirely to income-eligible households, according to Solar Power World. Community solar for low-income subscribers remains one of the few segments with strong bipartisan support, though its economics still depend on state incentive structures that vary widely.

The storage sector, meanwhile, is throwing around serious capital. GridStor's $220 million financing close for the 100 MW / 400 MWh White Tank project in Arizona adds to a wave of standalone battery deals that have accelerated even as policy headwinds mount. RMI's new analysis quantifies the tension: the sector is growing at roughly 30% annually, propelled by declining battery costs and the value storage provides to local grids, but tariffs on imported components, evolving Treasury regulations on tax credit transferability, and White House restrictions on foreign-made electrical equipment are all tightening the operating environment. For project sponsors lining up financing today, the question is whether that 30% clip holds through 2027 or whether the drag factors compound.
The data center boom is adding another variable. In Arkansas, Google's planned $4 billion data center in West Memphis involves Entergy as the utility partner and a "Fair Share Plus" cost structure. Google would contribute $526 million toward the Cypress Solar project and $190 million for transmission upgrades, but concerns are mounting over how the remaining costs are allocated — and whether the deal also locks in fossil fuel expansion alongside the solar buildout. Separately, a Trump adviser told Axios that ratepayer protection must be part of any permitting deal tied to AI infrastructure — a signal that even within the administration, the cost-shift question around hyperscale loads is registering politically. Read More: concerns are mounting, Axios.
Trina Storage is trying to meet data center demand from a different angle, unveiling the Elementa Hybrid Genset, which pairs gas generation with battery storage to serve AI data centers that face grid interconnection wait times of five to seven years in regions like Virginia, according to Energy Storage News. The product is a bet that behind-the-meter hybrid systems become the default bridge for power-hungry facilities that cannot wait for grid upgrades. Long-duration storage, too, is angling for a piece of the action: Hydrostor's Willow Rock advanced compressed air energy storage project in California is being watched as a test of whether A-CAES technology can achieve commercial viability outside China, where conventional CAES has so far been the only market to scale.

On the residential side, Pila Energy launched home battery storage in New York City, including a pilot with Brooklyn SolarWorks pairing rooftop solar with plug-in battery systems and a community program for group savings, Solar Power World reported. The timing matters: Con Edison's ongoing interconnection disputes with storage developers, covered in yesterday's briefing, have slowed community-scale battery deployment across the city, potentially making home-level systems a more accessible entry point for New Yorkers seeking backup power.

Wind Energy
The biggest clean energy story of the day is the lawsuit filed by the attorneys general of New York and California to block the Trump administration's cancellation of offshore wind leases and projects. The legal challenge — reported by the Seattle Times — escalates a conflict that has hung over the industry since the administration moved against federal offshore wind approvals. For developers with billions already sunk into East and West Coast projects, the suit is now the most consequential pending legal action in U.S. renewable energy. Its outcome will determine whether canceled lease agreements can be reinstated and, more broadly, whether the federal government can unilaterally void competitive lease sales after developers have committed capital. Read More: Seattle Times.
The filing comes just days after Ørsted completed installation of the final turbine at the 704 MW Revolution Wind array off the New England coast — proof that projects far enough along in construction can still cross the finish line. But for anything earlier in the pipeline, the legal trajectory of this suit will shape investment decisions for years.
Policy & Markets
U.S.-China tensions are adding a layer of complexity to clean energy finance. Nathan Picarsic of Horizon Advisory, speaking at an industry summit in California, discussed how transferability of tax credits and geopolitical friction are reshaping how battery storage and renewable projects get financed, according to Energy Storage News. The transferability mechanism — which allows project developers to sell tax credits to unrelated corporate buyers — has become a critical financing tool. But uncertainty around Treasury's implementation rules, combined with potential restrictions on Chinese-origin battery components, is pushing sponsors to restructure deals and seek domestic supply chain commitments that can be more expensive. Read More: Energy Storage News.
That dynamic maps directly onto the broader storage picture RMI described: a sector growing at 30% that faces a genuine question about whether policy friction will slow the money or merely reroute it. Developers sourcing from non-Chinese manufacturers may find tax credit eligibility smoother, but at higher hardware costs. Those sticking with Chinese suppliers risk regulatory complications but keep per-unit costs lower. Neither path is clean.
LOOKING AHEAD
- Offshore Wind Litigation Timeline: The New York and California lawsuit against the Trump administration's lease cancellations will move through federal court in the coming months — watch for early procedural rulings that could signal whether temporary injunctions are in play.
- Oak Run Solar Construction Start: With the Ohio Power Siting Board permit now final, Savion's 800 MW Oak Run project enters its pre-construction phase; any remaining county-level challenges or interconnection hurdles in PJM will determine the actual timeline.
- Data Center Cost Allocation Fights: The Google-Entergy deal in Arkansas and the Trump adviser's comments on AI ratepayer protections suggest state utility commissions will face increasing pressure to define who pays for hyperscale load growth — expect filings in multiple jurisdictions before year's end.
TODAY'S QUICK ANSWERS
Q: What does the New York–California offshore wind lawsuit mean for developers with capital already committed to lease areas?
A: It's the most direct legal challenge yet to the administration's authority to cancel competitive lease sales retroactively. If the courts issue an injunction or ultimately reverse the cancellations, developers could recover lease rights and resume permitting. If the suits fail, those investments are likely written off — and no new federal offshore wind leasing is probable during this administration. The case will be watched as a test of executive power over energy development on the outer continental shelf.
Q: Can battery storage maintain 30% annual growth with tariffs and regulatory headwinds mounting?
A: RMI's data says yes for now, because falling cell costs and grid-level demand — especially from states with storage mandates and from data center developers — are outpacing the drag from tariffs and Treasury rule uncertainty. But the balance could tip if restrictions on foreign-made electrical components tighten further or if tax credit transferability rules become harder to navigate. Developers should model scenarios where hardware costs rise 10–15% from supply chain shifts and test whether project returns still clear their hurdles.
Q: Why should clean energy executives pay attention to the Google-Entergy deal in Arkansas?
A: Because it's becoming a template — and a warning. Google's $526 million toward the Cypress Solar project and $190 million for transmission show how hyperscale customers can drive renewable buildout. But the ratepayer backlash over residual cost allocation signals that utilities and commissions will demand tighter cost-sharing frameworks. Any developer planning to serve data center load through a utility partnership should expect public scrutiny of who benefits and who pays.
THE BOTTOM LINE: The offshore wind fight has moved from executive action to the courts, storage capital keeps flowing even as policy friction builds, and the data center power grab is forcing every state to decide who picks up the tab — three fronts that will define clean energy investment risk through 2027.
