Treaty Oak Clean Energy has agreed to buy a 250 MW solar and storage project from Galehead Development. It is the second time in less than a year that Treaty Oak has bought from Galehead in the same market. Both companies also share a backer. That combination makes this less a one-off acquisition than a supply line.
Key takeaways
- Treaty Oak Clean Energy announced on 16 January 2024 that it had agreed to acquire a 250 MW solar and storage project in the US from Galehead Development, with the deal value undisclosed.
- Treaty Oak's 250 MW Galehead project is late-stage and under development, with commercial operations expected in the first half of 2026.
- Based on the location in Treaty Oak's press release, Enerdatics understands that the 250 MW Galehead solar and storage project is located in Texas, with Treaty Oak describing MISO-South as a priority market.
- Treaty Oak previously acquired two solar and storage projects totalling 465 MW in MISO-South from Galehead Development in March 2023, expected to reach commercial operations in the first half of 2025.
- Macquarie Asset Management's Green Investment Group acquired Treaty Oak Clean Energy in December 2022 and invested in Galehead Development in July 2022.
What is Treaty Oak buying from Galehead?
Treaty Oak is buying a late-stage project, which means it has moved well past the early site and permitting work but has not yet started construction. Leap records it as 250 MW of utility-scale solar paired with storage, with commercial operations expected in the first half of 2026.
Late-stage projects sit at a useful point for a buyer that wants to build. Much of the development risk has been retired, yet the buyer still controls construction, procurement and final financing. Treaty Oak describes its growth model as a mix of greenfield development and acquisitions, and late-stage purchases fill the gap between the two.
The deal also includes a joint investment in ReAcre, Galehead's land conservation initiative. The same feature appeared in Treaty Oak's first Galehead purchase in March 2023. Its repeat suggests the conservation element is part of how the two companies work together rather than a detail of one deal.
Why does Treaty Oak keep buying from the same developer?
Because repeat buying from one developer lowers the cost of each deal. The first transaction, in March 2023, covered two solar and storage projects totalling 465 MW in MISO-South. Ten months later, Treaty Oak returned for a third project. Across the two deals, Treaty Oak has agreed to buy 715 MW from Galehead.
Each repeat transaction can reuse what the first one built. Legal templates, due diligence processes and working relationships carry over. The buyer knows how the developer prepares projects. The developer knows what the buyer will pay for.
Galehead has a deep pool to draw from. It holds a 1.3 GW development pipeline in MISO-South markets and, according to Leap, a track record of more than 6 GW of development asset sales across US energy markets. For Treaty Oak, that makes Galehead a source of future deals as well as past ones.
How does Macquarie connect buyer and seller?
Through ownership on both sides. Macquarie Asset Management's Green Investment Group, known as GIG, invested in Galehead Development in July 2022. Five months later, in December 2022, it acquired Treaty Oak Clean Energy.
That gives Macquarie a stake in both the developer that sells projects and the platform that buys them. The arrangement is not unusual in infrastructure investing, where a sponsor may back a developer to originate projects and an operator to build and own them. It does, however, mean that the price agreed between Treaty Oak and Galehead is set between two companies with a shared backer, and it was not disclosed.
The timing is consistent with that structure. Treaty Oak's first Galehead purchase came about three months after GIG acquired Treaty Oak. The second followed within a year. Leap's records do not say whether the deals were run as competitive processes.
Treaty Oak has since moved projects in the region into construction. Its later $410 million financing for the 185 MW Beekman solar project in Louisiana shows the kind of capital stack it uses once a project is ready to build, as covered in Treaty Oak's Beekman solar financing.
Where exactly is the project?
Leap's record carries a hedge here. Based on the location given in Treaty Oak's press release, Enerdatics understands that the 250 MW project is located in Texas. The same announcement describes the project as offering opportunities to partner with communities and energy consumers in MISO-South, which Treaty Oak calls a priority market because of robust market fundamentals.
MISO-South is the southern region of the Midcontinent Independent System Operator, the grid operator covering much of the central US. Most of Texas sits in a different grid, ERCOT, so the location matters for how the project would sell its power. The record does not resolve which market the project will connect to, and this analysis does not assume one.
Enerdatics' data shows how little pricing surfaces in this segment. Leap records 53 development-stage US solar transactions tagged to MISO and announced in 2023 and 2024. Only 6 yield a developer premium, with a median of $0.13 million per MW. Of the 18 tagged as late-stage, just 3 carry a developer premium, at a median of $0.05 million per MW. Neither of Treaty Oak's Galehead deals has a disclosed value, so neither appears in those figures.
What does the deal signal for MISO-South solar?
It signals that platform buyers are locking up development supply through relationships rather than one-off auctions. A buyer that can return to the same developer for successive projects gains a predictable pipeline in a market where late-stage assets are sought after.
That fits the wider pattern in MISO. Buyers have been moving capital toward permitted, late-development projects with a visible route to construction, as Qualitas Energy's Illinois purchase showed in MISO's shift toward de-risked development assets.
The question is pricing. With shared ownership and no disclosed values, it is hard to tell whether repeat deals between affiliated companies clear at market levels. The 465 MW from the first deal was due to reach operation in the first half of 2025, a year ahead of this project. Its progress is the best guide to whether the relationship delivers.
