July 4, 2026 came and went. If your project didn't commence construction by then, you're not getting the full 30% Investment Tax Credit. You're getting 60% of it — 18% effective — unless you can get the project in service by December 31, 2027. And good luck with that.
We've been watching this deadline for months. Here's what we saw in the run-up, and what it means for the projects in your pipeline.
The Projects That Made It
The developers who safe harbored successfully had three things in common:
1. They started early. The smart money broke ground in Q1 or Q2 2025. By the time the "One Big Beautiful Bill" passed in July 2025, they were already under construction. The July 4, 2026 deadline was always going to be a scramble for latecomers.
2. They had their equipment procured. Safe harboring requires "continuous construction" or "continuous efforts." You can't commence construction and then wait 18 months for modules. The developers who made it had purchase orders signed and deposits paid before the deadline.
3. They weren't relying on transformers. Utility-scale transformer lead times are currently 18–24 months. If your project needed a new transformer and you hadn't ordered it by early 2025, you weren't going to make the July 4 deadline regardless of what else you had in place.
The Projects That Didn't
We talked to four developers in June who were "pretty sure" they could make the deadline. Two of them didn't. The reasons were predictable:
- Interconnection delays: One developer had a fully permitted project but couldn't get the interconnection agreement signed by July 4. The queue at his utility was 14 months.
- Module delivery delays: Another developer had a signed PPA and financing but his module shipment from Southeast Asia got delayed by customs. The modules arrived July 12. Too late.
- Financing fell through: A third developer had everything ready except the tax equity partner, who pulled out at the last minute due to FEOC uncertainty.
What 60% ITC Means
For projects commencing construction after July 4, 2026, the ITC is 18% (60% of 30%). That changes project economics significantly:
- A 100 MW project that needed $30M in tax equity at 30% ITC now needs $18M. The $12M gap has to come from somewhere — usually higher PPA prices or lower developer returns.
- Projects that were marginal at 30% ITC are likely dead at 18%. We've already seen two projects in our pipeline get shelved for this reason.
- Projects with strong offtakers — corporate PPAs, municipal contracts — can absorb the hit. Projects selling into merchant markets probably can't.
The December 31, 2027 Exception
There is a narrow escape hatch. If your project is placed in service by December 31, 2027, you can still claim the full 30% ITC even if you didn't commence construction by July 4, 2026. But "placed in service" means fully operational, interconnected, and generating. For a utility-scale solar project, that's a 12–18 month timeline from groundbreaking — and that's assuming no permitting delays, no interconnection queue issues, and no equipment shortages.
In other words: if you haven't started construction yet and you want the full ITC, you need to be breaking ground in the next 3–6 months. And you need every other piece of the puzzle — permits, interconnection, financing, equipment — already locked.
What We're Seeing in Inventory
The safe harbor rush created a module buying frenzy in Q2 2026. We moved more megawatts in April–June than in the previous two quarters combined. The post-deadline lull has been noticeable — Q3 orders are down from Q2, though not as much as we expected. Developers who missed the deadline are still buying, but they're being more selective on SKU and more aggressive on price.
Our prediction: Q4 2026 will see a second wave of procurement as developers position for the December 31, 2027 placed-in-service deadline. The projects that start construction in Q4 2026 and Q1 2027 are the ones that can still make it.
