Tax credit confusion is the real deadline problem for US solar and wind developers

The date that matters most is not a policy announcement but a calendar entry: the end of 2027. "Those credits go away if your project isn't placed into service by the end of 2027," said Heather Cooper, a partner at the law firm McDermott Will & Schulte. She spoke at a Canary Media Forum reported by Canary Media on 3 November.

The forum was titled "Hold onto Your Tax Credits: How to Get Ahead of the 2027 Deadline." Intersolar & Energy Storage North America sponsored it. It brought together a tax attorney, a project developer, a procurement specialist and a manufacturer. Its subject was less the deadline itself than the uncertainty around who still qualifies.

That uncertainty has a legislative origin. The One Big Beautiful Bill Act, signed in July 2025, sharply shortened the timeline for wind and solar projects to claim the investment tax credit and production tax credit. It also tightened the requirements to qualify, Canary Media reports. The law gave projects one year to begin construction to keep eligibility, a countdown that ended on 4 July 2026. Projects that met that date generally have four calendar years after construction began to be placed in service. For projects started this year, that means the end of 2030.

On paper those are hard dates. In practice the definitions do the work. The Internal Revenue Service lists five factors it weighs when deciding whether a project is in service. They include permits and licences, completed critical preoperation tests and synchronisation with the grid. Because the agency evaluates them case by case, Cooper said a project does not necessarily have to satisfy all five. That makes certainty hard to come by. Beginning construction is similarly elastic. Under IRS rules a developer can qualify by performing significant physical work on or off site. A developer can also qualify by paying or incurring at least 5 percent of total project costs, often through module or equipment purchases.

Old certainties, then a shorter runway

The contrast with 2022 is stark. When Congress passed the Inflation Reduction Act in August 2022, developers got what Canary Media describes as long-term certainty: a decade of reliable access to the ITC and PTC. One analysis cited by the outlet projected an additional 155 gigawatts of solar and wind capacity by 2030 and more than $270 billion in additional investment. The OBBBA was expected to crush clean-energy growth. Canary Media notes it did not, but its most immediate effect was confusion over access, duration and requirements.

Developers who appear to have missed the 4 July cutoff may still have options. Cooper said reviewing what was done before that date can matter. That includes smaller equipment contracts, tracked internal costs or early site work. The forum's practical advice points the same way: document the record rather than rely on a single filing date.

Transport funding shows a parallel squeeze. The Bipartisan Infrastructure Law's $36.8 billion in advance appropriations for transportation expired on 30 September 2026. A short-term extension to 11 December 2026 does not include those guaranteed dollars, according to a CleanTechnica piece republished from NRDC on 2 November. The same article cites an update to the Senate Commerce Committee's Chopping Block report on 27 October 2026, led by Ranking Member Cantwell. That update assesses state-by-state harm if the funding is not renewed. The House BUILD America 250 Act proposal released in May would cut all advanced appropriations and reduce transportation funding by almost 50 percent against current law, the article says.

Capital keeps moving elsewhere

Other regional technology bets are advancing on clearer terms. LG CNS said on Monday that it had completed a 30MW AI data centre in Jakarta. It is the first AI data centre built for an overseas client by a South Korean company. LG CNS plans to expand across Asia-Pacific, including Malaysia, Thailand, Vietnam, the Philippines and Japan, Light Reading reported on 2 November. KMG commissioned the facility, a joint venture between Indonesia's Sinar Mas Group and Korea Investment Real Asset Management. It sits under a contract worth 100 billion Korean won (US$74.52 million). It has 46,281 square metres of floor area, can house more than 100,000 servers and supports more than 300 kilowatts per rack. A next phase is designed to take total capacity to 400MW.

"Completing the AI data center in Indonesia is a meaningful achievement, demonstrating our ability to bring the expertise we have developed in Korea to overseas customers," LG CNS CEO Hyun Shin-kyoon said, according to The Korea Times, as quoted by Light Reading. Yoo Ki-woong, vice president of the company's AI and cloud business division, told The Elec that the Jakarta facility was fully leased before completion.

In Abu Dhabi, OpenAI signed agreements spanning energy, government and investment on Monday, CNBC reported on 2 November. ADNOC and G42 agreed to deploy OpenAI frontier technology across ADNOC's operations. Mubadala and Inception42 signed an agreement on AI for investment analysis. Inception42 and OpenAI signed a five-year agreement covering government, enterprise and education. CNBC also reported that OpenAI is seeking to raise up to $20 billion in a new round co-led by UAE investors.

Public money is moving too, at smaller scale. Sandia National Laboratories was selected for $3.38 million in Department of Energy funding to develop analytical tools for next-generation reactor fuels. The award is part of the up to $50 million HORNIG programme run by ARPA-E, HPCwire reported on 2 November. DOE Under Secretary for Nuclear Security Brandon Williams announced it at a news conference in Albuquerque on Friday.

Back in tax credits, the deadline is fixed but the qualifying test is not. That gap, rather than the date, is what developers are being told to plan around.
