HASI has put $143 million into a 605 MW portfolio of AES solar and storage assets. Divide one by the other and the deal prices at $0.24 million per MW, the lowest figure among priced US distributed solar transactions Enerdatics records across 2023 and 2024. Yet AES did not sell the assets. It still owns and operates every one of them.
Key takeaways
- HASI, formerly Hannon Armstrong, announced on 4 January 2024 a structured equity investment in a 605 MW portfolio of operational solar and solar-plus-storage assets developed, owned and operated by AES, under an agreement signed on 22 December 2023.
- The HASI investment in the AES solar portfolio was not priced at announcement; Enerdatics identified the value as $143 million, a figure AES Renewables later stated as the total consideration in its 2024 annual report.
- The AES portfolio comprises more than 200 operational projects, primarily community solar and commercial and industrial solar, across seven power markets and 11 US states, with more than 30 percent of capacity paired with battery storage.
- Power from the AES portfolio is sold to investment-grade corporate, utility and municipal offtakers under contracts with a weighted average remaining life of 16 years.
- Among nine priced operational US distributed solar deals Enerdatics records from 2023 to 2024, the median value is $1.15 million per MW, and the HASI and AES transaction, at $0.24 million per MW, is the lowest.
What did HASI actually buy?
A contracted share of the portfolio's economics, not the portfolio itself. Structured equity is an investment that sits in the ownership structure of an asset but whose returns are set by negotiated terms rather than by a simple percentage of the whole. The investor puts in capital and receives a defined claim on cash flows. The sponsor keeps control.
That is exactly the split Leap records here. After the investment, AES continues to own and operate the assets. HASI provides capital and receives returns from the portfolio's contracted revenue. Leap does not record what share of the portfolio's cash flows HASI's investment buys, and neither company disclosed one.
That missing number matters more than the headline figure. When a buyer takes a known minority stake, the price can be grossed up to an implied value for 100 percent of the assets. Here there is nothing to gross up with, so the $143 million can only be read as the cost of a slice of unknown size.
Why does $0.24 million per MW not mean the assets were cheap?
Because the numerator and the denominator measure different things. The $143 million buys part of the economics. The 605 MW is the whole portfolio. Dividing one by the other produces a figure that looks like a market low but is closer to an arithmetic mismatch.
A rough check shows the scale of the gap. At the slice median of $1.15 million per MW, the full 605 MW would imply a value of around $696 million. HASI's payment is about a fifth of that. That does not mean HASI holds a fifth of the portfolio, because structured equity rarely maps onto a clean ownership percentage. It does show that the payment is sized as a slice and should be compared with other slices, not with outright acquisitions.
The way the price surfaced reinforces the point. The deal value was not disclosed when the investment was announced. Enerdatics identified it, and AES Renewables confirmed the total consideration of $143 million in its 2024 annual report, close to a year after signing.
Why would AES sell cash flows rather than assets?
Because it wants the capital without giving up the platform. Leap records that the investment will free up capital for AES to develop and build new clean energy projects in the US. Selling the assets outright would also raise capital, but it would hand operation and the long-term relationship with offtakers to someone else.
The relationship between the two companies made this route straightforward. HASI and AES have a six-year partnership that included a previous equity investment by HASI in a utility-scale solar and wind portfolio. A repeat investor already understands the sponsor's assets, contracts and reporting, which shortens diligence and makes a bespoke structure easier to agree.
For HASI, the attraction is the opposite side of the same trade. It gets exposure to long-dated contracted cash flows across hundreds of small projects without having to run them.
What makes these contracts worth paying for?
Their length, their counterparties and their spread. A weighted average remaining contract life of 16 years means most of the revenue is fixed well into the 2030s. Enerdatics understands that the offtakers' credit ratings range from Aaa to Baa3 on Moody's scale, which is the band normally described as investment grade.
The spread matters too. More than 200 projects across seven power markets and 11 states means no single grid, regulator or customer dominates the cash flows. Community solar, in which many households or businesses subscribe to a share of one project's output, adds a further layer of diversification. That kind of granular, contracted income is why community solar capital is often priced in ways that a simple per MW figure misreads.
Enerdatics' data shows how thin the priced evidence is. Enerdatics records 42 operational US distributed solar transactions announced in 2023 and 2024, and only nine carry a value that can be expressed per MW. Across those nine the median is $1.15 million per MW, the interquartile range runs from $0.83 million to $1.40 million, and the full range from $0.24 million to $2.12 million. The two closest in size to the AES portfolio are a 600 MW deal at $250 million, or $0.42 million per MW, in November 2023, and a 340 MW deal at $145 million, or $0.43 million per MW, in December 2024.
What does the deal signal for US community solar capital?
It signals that sponsors are recycling capital through structures that keep ownership in place. HASI is an investor built for that kind of arrangement, and the AES transaction shows the template applied to a large operating portfolio of small projects. The seller funds its pipeline. The investor buys contracted yield. Operations do not change hands.
It also signals a disclosure problem for anyone benchmarking the sector. Most transactions in this market carry no price, and some of those that do are structured investments rather than acquisitions. A low per MW figure in this segment should prompt a question about what was bought before it is used as a comparable.
