TODAY'S LEAD: Michigan's massive 1,332 MW battery storage approval is now being paired with a landmark 12 GWh iron-air battery deal from Form Energy to power AI data centers, signaling that the explosive growth of artificial intelligence is fast becoming the dominant force reshaping America's energy storage buildout. Meanwhile, record-breaking 2025 solar and storage deployment numbers are landing just as federal policy uncertainty clouds the outlook for the years ahead.

Solar & Storage

The numbers from 2025 are now official, and they are staggering. U.S. small-scale solar installations reached a record 1.9 GW in the fourth quarter of last year, according to new federal data analyzed by PV Magazine USA. Distributed solar represented 15% of all new national power capacity in the quarter, driven in part by homeowners and businesses rushing to lock in the Section 25D residential tax credit before its scheduled phase-down. For the full year, solar accounted for a commanding 78% of the 46 GW of new generating capacity added to the American grid, with 15 GW of energy storage deployed alongside it.

But that record-setting momentum now faces a murkier road ahead. A new Wood Mackenzie analysis reported by Utility Dive projects that U.S. energy storage deployment could reach 52 GW by 2031 — yet cautions that uncertainty around load growth forecasts and the Trump administration's evolving posture on battery material sourcing and federal incentives could significantly alter that trajectory. The report highlights a tension now rippling through the industry: banner deployment years are running headlong into policy ambiguity that makes long-term planning treacherous.

That ambiguity, however, hasn't slowed the project pipeline this week. In Hawaii, the Public Utilities Commission approved AES Hawai'i's Kaawanui Solar project on Kaua'i, a 43 MW solar array paired with 172 MWh of battery storage that will power roughly 16,000 homes and supply 17.5% of the island's electricity, according to Solar Builder. Over its 25-year lifespan, the project is expected to offset 2.3 million metric tons of carbon emissions — a significant step for a state that remains uniquely dependent on imported fossil fuels and uniquely motivated to break that dependence.

On the mainland, Georgia Power broke ground on a 260 MW battery energy storage system in Jefferson County, designed to discharge over a four-hour period and bolster grid reliability across the state, as Solar Builder reports. The project, expected online in 2027, reflects the Southeast's accelerating pivot toward grid-scale storage to manage rising electricity demand — much of it driven by data centers and industrial load growth — while integrating growing renewable generation. This development comes just days after Arevon broke ground on its $600 million Cormorant storage facility in California, underscoring how battery buildouts are now a coast-to-coast phenomenon.

Perhaps the most consequential storage story, though, involves the intersection of artificial intelligence and long-duration energy storage. Michigan's Public Service Commission approval of six battery projects totaling 1,332 MW — first reported Monday — now includes a striking detail: Form Energy has signed a 12 GWh supply agreement to deploy its iron-air battery technology at new U.S. AI data centers, according to Energy-Storage.News. Among Michigan's approved projects is a 332 MW system specifically supporting an Oracle data center. The sheer scale of Form Energy's deal — iron-air batteries that can discharge for 100 hours at a fraction of lithium-ion's cost — signals that the data center boom is pulling entirely new storage technologies into commercial deployment far faster than many analysts anticipated.

On the residential storage front, New York homeowners are now positioned to earn financial incentives through NYSERDA and utility-run virtual power plant programs for installing home batteries. CleanTechnica reports that National Grid's ConnectedSolutions and Orange & Rockland Utilities' Smart Savers programs are paying residents to enroll their battery systems, effectively turning home storage into dispatchable grid assets. Meanwhile, Bluetti unveiled its new EnergyPro 13K system, a 13.2 kW residential battery compatible with both new and existing solar installations, further expanding consumer options in a market that is quickly maturing, per Solar Power World.

Wind Energy

Vestas secured a 135 MW turbine order for a U.S. project, according to reNEWS, a deal that adds to the Danish manufacturer's American onshore wind portfolio at a time when domestic wind development has been under sustained political pressure. While details on the project's specific location remain sparse, the order is a concrete sign that utility-scale onshore wind deals continue to close despite the broader headwinds facing the sector under the Trump administration.

The offshore wind picture, meanwhile, may be brightening — at least from Wall Street's perspective. Bank of America upgraded its outlook on Ørsted, the world's largest offshore wind developer, citing what it described as diminishing regulatory risk for the company's U.S. projects, Utility Dive reports. The analyst note points to improved conditions for offshore wind development under recent policy shifts, a notable assessment given that the Trump administration has actively offered lease buyouts to offshore wind developers and has been broadly skeptical of the technology. Whether BofA's optimism reflects a genuine policy softening or simply a market recalibration after months of worst-case pricing remains to be seen, but the upgrade sent a positive signal to an industry that has been starved of them.

Policy & Markets

A federal judge in Nevada cleared a major legal hurdle for a proposed lithium-boron mine, ruling against conservation groups who argued the project threatened a rare wildflower species, the Seattle Times reports. The decision carries significance well beyond the mine site: lithium remains a critical bottleneck for the battery storage systems powering America's clean energy buildout, and the ruling aligns with the Trump administration's broader push to accelerate domestic critical mineral extraction. For storage developers watching the Wood Mackenzie forecast and worrying about supply chain constraints, this is a welcome development — even as environmentalists warn about the ecological trade-offs of mining in sensitive landscapes.

At the state level, the role of legislatures in driving the clean energy transition continues to grow. CleanTechnica highlights how state lawmakers are increasingly filling gaps left by federal policy uncertainty, with environmental policy leaders pointing to clean energy standards, permitting reforms, and incentive programs as the primary engines of deployment in the current political environment. With the Trump administration's posture on renewable energy incentives and the Inflation Reduction Act's tax credits still evolving, the state-federal dynamic has become perhaps the most important variable in determining how fast — and where — clean energy gets built in America.

LOOKING AHEAD

IRA Tax Credit Clarity: With Wood Mackenzie flagging federal policy as the key variable in its 52 GW storage forecast, all eyes are on congressional action and Treasury Department guidance on battery material sourcing requirements and the phase-down schedule for residential and commercial clean energy tax credits.
Data Center Demand Reshaping Grid Planning: Form Energy's 12 GWh deal and Michigan's Oracle-linked storage approval suggest utility commissions nationwide will face an accelerating wave of data center interconnection requests — watch for how grid operators in Virginia, Texas, and Georgia respond in coming weeks.
Offshore Wind Lease Decisions Loom: Following BofA's Ørsted upgrade and the Trump administration's expanded lease buyout offers, several developers face critical go/no-go decisions on East Coast projects in the second quarter that will define the sector's near-term trajectory.

Today's Quick Answers

Q: What does Form Energy's 12 GWh iron-air battery deal mean for the broader storage industry?

A: It marks the commercial arrival of long-duration storage at a scale previously reserved for lithium-ion. Iron-air batteries can discharge for up to 100 hours at significantly lower cost per kilowatt-hour, making them uniquely suited for the steady, around-the-clock power demands of AI data centers. If Form delivers on this agreement, expect other long-duration technologies — including compressed air and flow batteries — to attract similar large-scale offtake deals within 12 to 18 months.

Q: Why should developers pay attention to the tension between record 2025 deployment and the uncertain 2026-2031 forecast?

A: Because the tax credit phase-down that helped drive last year's 1.9 GW distributed solar record and 15 GW of storage deployment was a pull-forward effect — projects accelerated to capture expiring incentives. Wood Mackenzie's cautionary note suggests the industry could face a deployment air pocket if federal policy on IRA credits and battery material sourcing isn't clarified soon. Developers with shovel-ready projects should prioritize locking in interconnection agreements and offtake contracts now, before the policy picture gets muddier.

Q: What does Bank of America's Ørsted upgrade signal about offshore wind's political risk?

A: It suggests Wall Street is beginning to price in a floor for U.S. offshore wind rather than continued deterioration. While the Trump administration remains broadly skeptical, the lease buyout program may have paradoxically reduced uncertainty by giving developers a clear exit option — meaning the projects that remain in the pipeline are the ones with the strongest economics and state-level support. That said, no new federal offshore wind lease sales are expected this year, so near-term growth depends entirely on projects already permitted or under construction.

THE BOTTOM LINE: The explosive demand from AI data centers is pulling unprecedented volumes of battery storage — including entirely new technologies like iron-air — into the American grid at a pace that is outrunning federal policy, making state-level action and private offtake agreements the de facto engines of the U.S. clean energy buildout in 2026.
