Solar & Storage

The SRP-NextEra deal dwarfs nearly every clean energy procurement agreement on record and delivers a clear market signal: even in a political environment where federal renewable incentives face uncertainty, utilities are making enormous long-term bets on solar and storage economics. Under the , NextEra will build 3,000 MW of solar generation and 1,000 MW of battery storage across multiple Arizona sites through 2027. The storage component is explicitly designed to manage evening peak demand — a persistent challenge in the desert Southwest — and reduce SRP's dependence on natural gas peaker plants. The deal underpins SRP's commitment to retire its remaining coal fleet by 2032, a timeline that now has contractual teeth behind it. Read More: power purchase agreement.

The Arizona mega-deal is the headline, but the pipeline beneath it is filling fast across multiple states. In West Texas a 140-MWDC utility-scale project in Snyder, has begun installation under developer Levona Renewables with financial backing from Energea. The project will use single-axis trackers and is expected to generate roughly 317 GWh annually — enough to make it a meaningful contributor to ERCOT's solar fleet. Texas remains the nation's most prolific solar market by installation volume, and Iron Spur's construction start suggests that developer confidence in the state's merchant and contracted power markets remains strong even as interconnection queues strain grid operators.

Meanwhile, the agrivoltaics movement is gaining sophistication and scale. In Illinois, the state's Shines program — which has now approved a staggering 3.6 GW of capacity — spotlighted the in Pontiac as a model for dual-use development. The 5-MWac community solar installation, which energized in February 2025, uses bifacial panels on 42 acres alongside livestock grazing and pollinator habitat, producing over 10,000 MWh annually. Illinois Shines has now approved 171 agrivoltaics projects, making the state a national laboratory for designs that ease the farmland-versus-solar tension that has stalled projects elsewhere.

That same dual-use philosophy is being pushed further in Tennessee, where at the Christiana Solar Ranch. The system integrates rotational cattle grazing directly with utility-scale solar arrays, supplying renewable power to Middle Tennessee Electric through a long-term PPA. Together, the Illinois and Tennessee developments suggest that agrivoltaics is graduating from niche pilot projects to a scalable strategy for overcoming local land-use opposition — a critical bottleneck in states across the Midwest and Southeast where county-level solar bans have proliferated.

On the storage side, Kansas delivered a significant win when Wyandotte County approved , a 300 MW battery system that will rank among the largest in the state. The Sierra Club and allied groups applauded the decision, framing it as a step toward grid reliability without new fossil fuel generation. This development comes as the domestic storage technology landscape itself is shifting: , announced it will pivot to manufacturing sodium-ion batteries designed by startup Alsym Energy. Sodium-ion chemistry avoids the lithium and cobalt supply chains that have created geopolitical and cost vulnerabilities, and the move positions ESS to serve a grid storage market increasingly hungry for alternatives. Separately, toward commercialization in the U.S., driven by data centers' insatiable demand for continuous, reliable power — a theme that is rapidly becoming the dominant demand driver for both storage and generation investments.

Wind Energy

No major U.S. wind project announcements emerged today, but the sector's story continues to be shaped by the broader forces covered in recent briefings — including the Democratic investigation into the Trump-TotalEnergies offshore wind deal reported earlier this week, and the Senate standoff over permitting reform that could directly affect onshore and offshore wind timelines. Developers and investors are watching those political dynamics closely heading into the summer construction season.

Policy & Markets

The most consequential policy development today sits at the intersection of energy and industrial policy. for its Georgia EV production facility — set to begin operations in 2028 — represents a striking outcome given the Trump administration's vocal opposition to EV mandates and its moves to roll back tailpipe emissions standards. The loan, which was originally structured under the Biden-era DOE lending program, appears to have survived internal administration review, suggesting that even skeptics of EV policy are reluctant to kill deals that create domestic manufacturing jobs in politically important states. Georgia, with its growing role as an EV and battery manufacturing hub, adds political weight to the decision. Read More: Rivian's $4.5 billion Department of Energy loan.

In Wyoming, the federal licensing of — backed by Bill Gates and positioned as the first advanced reactor built in the U.S. this century — received bipartisan celebration. The project aligns with the Trump administration's stated support for nuclear energy as part of an "all of the above" strategy, and Wyoming officials framed the approval as the beginning of a "nuclear renaissance." The reactor's construction is now underway, and its success or failure will likely shape federal appetite for licensing additional advanced designs. This comes on the heels of Iowa's nuclear tax breaks for reactor restarts, reported earlier this week, suggesting growing state-level momentum for nuclear across the heartland.

Out West, to resolve the long-running Colorado River water allocation dispute. While primarily a water management story, the implications for energy are significant: hydroelectric generation at Lake Mead and other facilities has been curtailed by drought for years, and any reallocation framework will directly affect the availability of firm, dispatchable clean power across the desert Southwest — the same region where SRP is now banking on 4 GW of solar and storage to replace coal. Read More: Lower Basin states including Nevada issued a new proposal.

On the international front, the financial distress of Chinese solar giants , both reporting significant losses, could have ripple effects for U.S. developers. Margin pressure in China's module sector may accelerate price declines for panels — a boon for American project economics — but could also trigger trade enforcement actions if dumping allegations resurface under the current administration's aggressive trade posture.

LOOKING AHEAD

• Arizona Solar Buildout Timeline: With the SRP-NextEra 4 GW deal signed, watch for specific site announcements and interconnection filings across Arizona in the coming weeks — the 2027 completion target leaves an extraordinarily tight construction window.
• Senate Permitting Reform Standoff: Democratic senators' threat to block bipartisan permitting legislation over the administration's renewables freeze remains unresolved; expect movement or escalation when the Senate reconvenes next week.
• Ohio Renewable Energy Ban Referendum: Richland County voters are approaching a May ballot decision on reversing a wind and solar ban, a bellwether for local energy politics across the Midwest.

THE BOTTOM LINE: The SRP-NextEra 4 GW deal, Kansas's 300 MW storage approval, and Rivian's DOE loan survival collectively demonstrate that market fundamentals and contractual momentum are overpowering political headwinds — the clean energy buildout is now too large, too distributed, and too economically compelling to reverse.
