The Cost of a Premium.

On July 8, 2026, Judge Ryan T. Holte of the United States Court of Federal Claims issued the long-awaited decision on remand in Alta Wind I Owner Lessor C v. United States (Nos. 13-402 et al. (Fed. Cl. July 8, 2026) (Holte, J.)). The opinion closes — for now — a dispute over how to measure the “eligible basis” of the largest wind-energy complex in North America for purposes of the Section 1603 cash-grant program. Commentators have called the reasoning “perplexing,” and in places it is. But underneath the perplexity sits a durable planning lesson that reaches far beyond wind turbines, and far beyond the now-expired grant program: you cannot conjure tax basis out of a purchase price. You have to substantiate it, cost by cost, and the difference between the two is where the money is lost.

This is a tax-developments note, not an asset-protection essay. The lesson here is a discipline of documentation and valuation. But it rhymes with the theme this series returns to again and again — that the strongest planning is the planning that was built and papered before anyone needed it to hold, and that improvised, results-driven characterization invites a court to unwind it.

Section 1603 of the American Recovery and Reinvestment Act of 2009 (Pub. L. No. 111-5, § 1603) let developers of renewable-energy property take, in lieu of the investment tax credit under Section 48, a cash grant from Treasury equal to thirty percent of the property’s eligible basis. Eligible basis, in turn, tracked the cost basis of the “specified energy property” — the tangible, depreciable generating equipment — under ordinary income-tax principles. The grant, like the credit it substituted for, rewarded investment in tangible property. It did not reward the purchase of contracts, permits, development rights, or goodwill.

That distinction is the whole case. When the Alta Wind projects in California’s Tehachapi region were sold and leased back, the buyers paid a great deal — Terra-Gen’s claimed expenditure ran to roughly $2.3 billion — and they allocated the overwhelming majority of it, between 93 and 97 percent, to the grant-eligible generating equipment (Norton Rose Fulbright, Tax Basis Issues: Alta Wind Round Three). On that basis they applied for more than $703 million in grants. Treasury paid $495 million, having concluded that a meaningful slice of the purchase price bought something other than turbines: power-purchase agreements, going-concern value, and intangible development rights that no grant would ever touch. The owners sued for the roughly $206 million shortfall.

The question never changed: how much of what a buyer paid is basis in tangible property, and how much is something else? The answers did.

In the first round, the Court of Federal Claims sided largely with the taxpayers, valuing the property by reference to the price paid in arm’s-length sales and declining to break the purchase price apart. In 2018, the Federal Circuit reversed and remanded (Alta Wind I Owner-Lessor C v. United States, 897 F.3d 1365 (Fed. Cir. 2018)), holding that these were “applicable asset acquisitions” and that the trial court had erred in refusing to apply the residual method of Section 1060. Section 1060 is not optional. Where a group of assets is transferred and goodwill or going-concern value “could under any circumstances attach,” the buyer must spread the purchase price across a seven-class waterfall, with tangible personal property in the middle classes and intangibles, goodwill, and going-concern value at the bottom. The Federal Circuit told the trial court to do exactly that — and, critically, to distinguish “turn-key value,” which travels with the tangible assets, from goodwill and other intangibles, which do not.

The July 8, 2026 opinion is the answer to that mandate. And it is a genuinely mixed result — which is precisely why it defies a tidy headline.

Judge Holte rejected the taxpayers’ valuation engine and much of the Government’s, then built basis back up cost by cost. Several holdings matter for planners:

The income method loses; the cost method wins. The taxpayers had relied on a discounted-cash-flow model — valuing the equipment by the future revenue it would generate, a stream that necessarily included the anticipated Section 1603 grant itself. The court refused this, finding it circular: the anticipated grant value, the court reasoned, “is not strictly attributable to tax benefits flowing from the eligible assets, but instead akin to a Class VI intangible” (Ed Zollars, Current Federal Tax Developments, July 11, 2026). In other words, you cannot inflate the tangible basis with the value of the grant you are trying to compute from that basis. The court adopted a modified replacement-cost approach instead — asking what a buyer would have to spend to build the same facility — on the intuitive premise that “the cost to build a wind farm is the same regardless of whether there is an intermediate transaction transferring the wind farm from party A to B” (Norton Rose Fulbright, Alta Wind Round Three).

Developer profit is real basis — if you can price it. Having chosen a cost approach, the court did not limit the taxpayers to bare construction costs. A buyer replacing the facility would have to pay a developer’s profit margin, and that margin is capitalizable. The court rejected the Government’s 9.03 percent figure as merely a weighted average cost of capital dressed up as a profit markup, and instead allowed market-derived developer profit of 15 percent on Alta I and 20 percent on the remaining five projects, drawn from the contemporaneous placed-in-service appraisals.

Some costs go in; some intangibles come out. The court capitalized interest during construction (~$48.1 million) under Section 263A(f), and permitted the $100.5 million Oak Creek development fee paid to buy out a co-developer as a capitalizable developer cost. But it segregated out, as grant-ineligible intangibles, the master power-purchase agreement, roughly $157 million of development rights, and residual going-concern value and goodwill under Sections 1060 and 197.

Turn-key value: zero, on these facts. This is the holding most likely to surprise. The Federal Circuit had said turn-key value belongs with the tangible assets. But on remand the court found that these contractors — not the developer — bore the turn-key risk, and had already priced it into their construction contracts. Adding a separate turn-key premium would double-count. So the court allowed no additional turn-key value.

Net the pieces together and the practical effect, as several observers noted, is modest: the decision is “unlikely to have much effect in practice” (Norton Rose Fulbright). A premium paid to a tax-equity partnership or downstream buyer does not, by itself, manufacture ITC or grant basis. What it does is send everyone back to their cost-segregation reports.

The label is fair in one respect. In endorsing the cost approach, the court also, in earlier remand analysis, treated the anticipated grant as a Class VI intangible — a characterization critics find hard to square with either the statute or ordinary valuation practice, and one the court never fully defines (Troutman Pepper Locke, Court Issues Perplexing Decision in Alta Wind). Taken to its logical end, the reasoning could sweep in any revenue stream. That is the perplexity.

But the discomfort is at the edges. The spine of the decision is orthodox and, for planners, clarifying: basis in tangible property is a cost concept, proven from the ground up, not a price concept inferred from what a motivated buyer was willing to pay. Strip away the wind-specific facts and the ruling is a master class in what a court will and will not credit when a taxpayer’s basis is challenged.

For clients and their advisors — whether the credit at issue is the old Section 1603 grant, today’s investment and production credits, or any deal where purchase price must be spread across tangible and intangible assets — Alta Wind distills to four disciplines.

1. Basis is substantiated, not asserted. The single most influential piece of evidence in the case was a contemporaneous cost-segregation study with a documented audit trail — over a thousand hours of vouching direct and indirect costs. A number pulled off a closing statement, unallocated and unaudited, is exposed to reallocation under the Section 1060 waterfall. The time to build that record is when the asset is placed in service, not when the examiner calls.

2. Section 1060 is mandatory in a business acquisition — plan the allocation, don’t inherit it. Where an acquisition sweeps up tangible property and contracts, permits, or goodwill, the residual method controls whether the taxpayer likes it or not. Sophisticated parties negotiate and paper the allocation at closing, backed by an appraisal, rather than leaving a court to impose one years later — usually less favorably.

3. Do not compute a tax benefit from a basis that already includes the benefit. The circularity that sank the DCF model is a recurring trap. Valuations that feed anticipated credits, grants, or subsidies back into the tangible basis they are supposed to measure will not persuade. Keep the incentive on the intangible side of the ledger where it belongs.

4. Isolate the intangibles yourself — before the Government does. Development rights, offtake agreements, permits, and goodwill are real value, but they are grant- and credit-ineligible. Identifying and pricing them in a contemporaneous appraisal is not a concession; it is what makes the remaining, tangible allocation defensible. A structure that pretends the intangibles do not exist invites a court to find that everything is intangible.

That fourth point is where this tax note meets the abiding theme of this series. In asset protection, the improvised, self-serving transfer made under the shadow of a claim becomes evidence rather than protection. In tax, the improvised, self-serving allocation — everything to the tangible asset, nothing to the contracts — becomes an invitation to reallocation. In both worlds, the discipline is the same: characterize honestly and contemporaneously, document it while there is nothing to prove, and let the record do the work when the challenge comes.

Alta Wind is, on its surface, a fight about turbines and a grant program that no longer takes applications. Read for its method, it is about something permanent: the gap between what you paid and what you can prove, and the cost of not closing it in advance.
