Trump's bulk-power equipment ban threatens to deepen America's transformer crisis
KEY DEVELOPMENTS
- Equipment Ban Expected to Worsen Transformer Shortage: Executive Order 14420 restricts foreign-made power transformers, inverters, and battery energy storage systems from the U.S. bulk-power system, primarily targeting Chinese manufacturers. The ban lands at a moment when transformer lead times already stretch beyond two years for some utilities. (PV Magazine USA) Read More: PV Magazine USA.
- BloombergNEF: Storage Delays and Cancellations Likely: An August 26 Trump executive order and related Treasury guidance on foreign entities are expected to significantly disrupt battery and inverter supply chains, causing delays and cancellations across the energy storage sector.

Solar & Storage
The twin blows from the Trump administration's grid-equipment policies dominated the day. Executive Order 14420, which restricts foreign-made high-voltage hardware from the U.S. bulk-power system, targets power transformers, inverters, and battery energy storage systems, with Chinese manufacturers bearing the brunt. Separately, BloombergNEF warned that the August 26 executive order and accompanying Treasury guidance on foreign entities will cause significant disruptions to battery and inverter supply chains used in energy storage projects. For developers with storage projects in interconnection queues, the message is blunt: procurement timelines just got longer and less certain. Read More: targets power transformers, inverters, and battery energy storage systems, cause significant disruptions.
The practical stakes are enormous. The U.S. already faces a well-documented transformer shortage, with utilities waiting years for delivery of large power transformers. Layering import restrictions on top of that backlog could slow not just clean energy interconnection but the broader grid buildout that data centers, industrial facilities, and electrification all depend on. Storage developers who source cells, modules, or power-conversion equipment from Chinese suppliers now face a dual squeeze — tariffs that were already raising costs and an outright ban that may eliminate some procurement options entirely.
On the project front, Encore Renewable Energy brought a 2.25 MW solar array online on a capped landfill in Derry, New Hampshire. The project is projected to save Derry taxpayers roughly $4 million in electricity costs over 25 years — a template for municipalities sitting on closed landfills that generate maintenance costs but no revenue. In Illinois, the Obama Foundation signed on as an anchor tenant for community solar projects developed by Reactivate, a deal structured to bring renewable energy access to the Obama Presidential Center in Chicago and to open subscriptions for low-to-moderate income households and small businesses. Anchor tenancy from a high-profile institutional offtaker can improve project bankability — a useful signal for the state's community solar market.

In the industry's supply chain, solar tracker manufacturer ARRAY Technologies acquired Affordable Wire Management, a provider of wiring and balance-of-system solutions for utility-scale solar and energy storage. The deal fits a broader pattern of tracker and racking companies expanding into adjacent BOS categories to offer developers a more integrated package — and, perhaps, to capture margin that tightening equipment-import rules could erode elsewhere.

Wind Energy
California's offshore wind ambitions took another hit. State officials announced plans to sue over a Trump administration deal that allowed RWE to exit its 1.6 GW offshore wind lease off northern California. The lawsuit opens a second legal front: just yesterday, California filed suit over the separate cancellation of the 2 GW Golden State Wind project and its $150 million lease buyout. Together, the two disputes put 3.6 GW of planned Pacific offshore capacity in legal limbo and signal that the state government intends to fight lease exits in court rather than accept them as fait accompli. For offshore wind developers still holding federal leases, the litigation creates a new layer of uncertainty — walking away may not be cost-free. Read More: sue over a Trump administration deal.
Onshore, Xcel Energy ran into a roadblock at the Colorado Supreme Court. The utility had sought expedited condemnation of a 550-foot strip of ranchland in Cheyenne County to route a transmission line connecting two wind farms to a substation. The court said no. The ruling doesn't kill the project, but it forces Xcel into a longer legal process and demonstrates the friction that even modest right-of-way disputes can add to wind interconnection timelines in Colorado.

Policy & Markets
New Jersey became the latest state to remove barriers to small-scale residential solar. Governor Mikie Sherrill signed the Garden State Balcony Solar Act, which lets residents install portable, plug-in solar devices up to 1,200 watts without permits or utility approval. Critically, the law bars landlords and municipalities from blocking the installations — a provision aimed squarely at renters who have historically been locked out of rooftop solar. The 1,200-watt cap keeps systems small enough to plug into a standard outlet, but for a renter in a sunny apartment, that can meaningfully dent a monthly electricity bill. Read More: without permits or utility approval.
California's legislature kept busy on the distributed-energy front as well. One bill advancing through the statehouse would allow remote inspections for residential solar and energy storage systems, a measure that could shorten the weeks-long wait for in-person inspectors that plagues many rooftop installations. Separately, virtual power plant legislation now awaits Governor Newsom's signature. If signed, those VPP bills could reshape how aggregated distributed resources participate in the state's grid — a market that Octopus Energy US is betting on after completing its investment in Uplight, a distributed energy resource flexibility platform. Read More: allow remote inspections, awaits Governor Newsom's signature.
In Wisconsin, Milwaukee residents and environmental activists pushed back against We Energies' proposed rate increase. Opponents cited concerns about ratepayer funding for data center infrastructure and criticized the state's lag in renewable energy development. The fight echoes a nationwide tension: utilities are asking regulators to approve capital spending tied to surging data center load, while consumer advocates question whether residential customers should shoulder those costs.

LOOKING AHEAD
- California Offshore Wind Litigation: With lawsuits now filed or planned over both the Golden State Wind and RWE lease exits — totaling 3.6 GW — watch for the federal government's response and any ripple effects on remaining Pacific lease holders.
- Newsom's VPP Decision: California's virtual power plant bills sit on the governor's desk. A signature would create a framework for aggregating distributed batteries, EVs, and solar into grid resources — a potentially large market for DER platform companies.
- Storage Supply Chain Fallout: BloombergNEF's warning about project delays and cancellations from the Trump administration's equipment and foreign-entity rules will sharpen as developers reassess procurement strategies and project economics heading into Q4.
TODAY'S QUICK ANSWERS
Q: What should storage developers do now about the bulk-power equipment ban and foreign-entity guidance?
A: Audit your supply chain immediately. Executive Order 14420 and the Treasury's foreign-entity rules create overlapping restrictions on Chinese-made transformers, inverters, and battery systems. Projects that haven't locked in domestic or allied-nation sourcing for key components face the real possibility of delays or cancellations, according to BloombergNEF's assessment. Developers with projects nearing financial close should pressure-test whether their equipment suppliers can deliver compliant hardware on the original timeline.
Q: Why does California's second offshore wind lawsuit matter beyond the state's borders?
A: Because it establishes that exiting a federal lease may trigger state legal action — not just federal penalties. If California can impose costs on departing leaseholders through litigation, it changes the risk calculus for any developer considering abandoning offshore wind leases nationwide. With 3.6 GW now in dispute on the Pacific coast alone, the outcome could determine whether lease exits become routine or legally fraught.
Q: Does New Jersey's balcony solar law signal a trend other states will follow?
A: The 1,200-watt, no-permit model directly addresses two persistent barriers — renter exclusion and permitting delays — that frustrate residential solar adoption everywhere. The provision blocking landlords and municipalities from interfering is the key innovation. States with large renter populations and high electricity prices are the most likely to replicate it, though utilities will push back if plug-in systems grow large enough to affect distribution planning.
THE BOTTOM LINE: The Trump administration's equipment restrictions are compounding an already strained grid-hardware supply chain, and developers who haven't diversified procurement away from Chinese suppliers are running out of runway.
