Solar & Storage
DTE Energy's 132-MW Fish Creek Solar Park, sited near Sheridan in Montcalm County, Michigan, is now feeding electrons to the grid — and it got there through an unusual funding mechanism. The $268 million project was entirely financed through DTE's MIGreenPower voluntary customer program, meaning ratepayers who opted into the program, rather than general rate base, underwrote construction. For developers watching how utilities green their portfolios without triggering rate case battles, the model matters: it shifts cost recovery from contested regulatory proceedings to willing subscribers. DTE says Fish Creek can power approximately 30,000 homes, adding meaningful utility-scale solar capacity to a state that has historically leaned on gas and nuclear. PV Tech. Read More: PV Tech.
Michigan had a busy energy week beyond solar. Energy Secretary Chris Wright visited the Palisades nuclear plant in Covert, a facility that shut down and is now in line to become the first U.S. nuclear plant to resume operations, backed by a $1.5 billion loan announced under the previous administration. The visit carried political overtones — it took place in a competitive House district — but the technical question for the grid is whether Palisades can actually restart, a feat no American reactor has accomplished. If it does, it would add significant baseload clean generation to a state simultaneously building out solar.
Across the supply chain, the post-OBBBA landscape is coming into sharper focus. After President Trump signed the legislation in 2025, restricting solar developers' access to Section 48E investment tax credits and limiting foreign entity involvement in projects claiming those credits, the industry responded with a massive safe-harboring push. Developers locked in roughly 200 GW of solar projects through 2025, PV Magazine reports. Supply chain dynamics have shifted toward domestic module production as developers try to maximize remaining tax credits, even at premium pricing. The long-term question is whether the safe-harbored pipeline can convert to built megawatts before expiration deadlines hit — a challenge given interconnection queues and permitting timelines that the industry was already struggling with before the policy shift.

On the manufacturing side, APA Solar is running facilities in northwest Ohio — in Ridgeville Corners and Bryan — producing foundations and racking for utility-scale solar projects. The company, which grew out of automotive supply chain expertise, makes driven piles, screw piles, helical piles, and ballasted foundation systems. With domestic content requirements increasingly driving procurement decisions under the new tax credit regime, suppliers like APA that can stamp "Made in America" on structural components are positioned to capture business that might otherwise go offshore.

Battery storage, meanwhile, continues to prove its worth on the grid. A Rocky Mountain Institute report released this week found that utility-scale batteries delivered 6–19% of California's electricity during peak demand events and now run at capacity factors similar to gas peaker plants. The analysis covered multiple regions including Texas and California and concluded that batteries are saving grid operators hundreds of millions of dollars annually while improving reliability. For storage investors, the RMI data offers a compelling counterpoint to skeptics who question whether batteries can perform as reliably as gas peakers — the answer, increasingly, is yes.
FranklinWH is extending the distributed side of the storage equation. The company announced new virtual power plant partnerships with Alliant Energy in Iowa and Entergy Louisiana in Louisiana, deploying residential energy storage systems that can be aggregated and dispatched as grid resources. These VPP programs are small individually but represent a growing trend: utilities treating rooftop batteries not as isolated customer assets but as dispatchable fleet capacity. Energy Storage News.

Policy & Markets
The DOE's $5.1 billion loan closure for Alliant Energy is the week's biggest financing story — and also one of the most complex. As Power Magazine reported, the federally guaranteed package covers not just battery energy storage but also natural gas generation and power plant upgrades across Iowa and Wisconsin. That blend mirrors a tension running through federal energy policy right now: even programs designed to accelerate the energy transition are financing significant new gas capacity. The lower-cost federal financing gives Alliant a capital advantage over peers raising debt at market rates, which could shape competitive dynamics across the Upper Midwest.

On Capitol Hill, permitting reform legislation is generating heat from both flanks. A key Democrat warned that the permitting bill could create a "gold rush for gas" by streamlining approvals in ways that disproportionately benefit fossil fuel infrastructure rather than renewable energy projects, Axios reported. Separately, Senate backers of the bill are trying to build a large vote margin to send a political signal to the House, where passage is less certain. For solar and wind developers, the outcome matters directly: permitting timelines remain one of the biggest bottlenecks for turning interconnection queue positions into operational projects.

State-level regulatory fights are drawing political attention, too. In Arizona, Democrats are targeting utility commission seats as rising electricity costs give them a campaign issue, according to Inside Climate News. Commission composition can determine everything from rate structures to renewable portfolio standards — making these races consequential for developers with projects in the state's pipeline. In Nevada, NV Energy's proposed daily demand charge has prompted questions about who is funding advertising campaigns in support of the rate structure, a fight that could influence how rooftop solar and distributed storage economics pencil out for residential customers.

LOOKING AHEAD
- Permitting Reform Vote Count: Senate leadership is pushing for a large bipartisan margin on the permitting bill to pressure the House, where the legislation's fate — and its implications for renewable energy project timelines — remains uncertain.
- Palisades Nuclear Restart Timeline: Energy Secretary Wright's visit to the shuttered Michigan plant keeps the spotlight on whether the $1.5 billion federal loan can deliver the first-ever restart of a U.S. nuclear reactor, a decision with implications for baseload clean energy in the Midwest.
- Arizona Corporation Commission Races: With elections approaching, the composition of Arizona's utility regulatory body could shift, potentially reshaping rate design and renewable energy procurement rules in one of the country's strongest solar markets.
TODAY'S QUICK ANSWERS
Q: What does the 200 GW safe-harbor rush mean for solar project timelines over the next two years?
A: Developers locked in tax credit eligibility for roughly 200 GW of solar after the OBBBA restricted Section 48E credits, but safe-harboring only preserves the financial incentive — it doesn't solve interconnection queues, permitting delays, or equipment procurement. The real test is conversion rate: how many of those megawatts get built before safe-harbor windows expire. Developers with secured land, grid positions, and domestic module supply contracts are best positioned; those still waiting on interconnection studies face a ticking clock.
Q: Why should storage developers pay attention to the RMI battery performance data?
A: The finding that batteries supplied 6–19% of California's peak electricity and match gas peaker capacity factors gives storage advocates hard numbers for regulatory proceedings and financing conversations. Lenders and utility procurement teams have historically discounted battery reliability relative to gas; data showing comparable performance erodes that discount, potentially lowering cost of capital for storage projects and strengthening their position in competitive solicitations.
Q: What's at stake for clean energy in the permitting reform debate?
A: The central risk is asymmetry — if the bill streamlines permitting in ways that primarily accelerate gas infrastructure while offering less relief for renewables, it could widen the competitive gap at a moment when solar and wind developers are already navigating tighter tax credit rules. Developers should watch the final legislative text for how environmental review timelines, transmission siting authority, and categorical exclusions are structured across fuel types.
THE BOTTOM LINE: Federal dollars are flowing to both gas and clean energy through the Alliant loan and safe-harbored solar credits, but the permitting reform fight on Capitol Hill will determine which technology can actually get built faster — and that race is far from settled.
