When Ferrovial announced its first renewable energy investment in the United States, a 257 MW solar project in Leon County, Texas, it named neither the seller nor the price. Enerdatics identified both at the time. Ferrovial's own annual report later confirmed them. The price is small enough to look like a mistake, and the reason it is not says a lot about how Texas solar changes hands.
Key takeaways
- Ferrovial acquired a 257 MWdc solar project in Leon County, Texas, recorded by Enerdatics on 1 May 2024, as Ferrovial Energy's first renewable energy investment in the United States.
- Ferrovial's annual report shows that its subsidiary Ferrovial Energy US LLC acquired 100 percent of Misae Solar IV, LLC, the project company owned by Misae Energy, for $14.3 million (EUR 13.8 million).
- Enerdatics identified Misae Energy as the seller and the deal value at about $14 million before any public disclosure by the buyer or seller, a finding later confirmed by Ferrovial's annual report.
- The Leon County solar plant was set to begin construction in the quarter the deal was announced with power generation from 2026, and is expected to produce about 475 GWh of electricity a year.
- Ferrovial described its first US renewable investment as totalling $72 million, and its agreement covers the construction and operation of the Leon County project.
What did $14.3 million actually buy?
It bought a project company, not a power plant. Misae Solar IV, LLC is a special purpose vehicle: a company set up to hold one project's land rights, permits, grid connection application and contracts, so that the whole bundle can be sold by transferring the shares. Ferrovial bought all of it.
The project was ready to build at the time of the deal. Ready-to-build means the development work is done: the site is secured, permits are in hand and the project can start construction. What it does not include is any steel in the ground. That is why the price looks so low against the size. At $14.3 million for 257 MW, Ferrovial paid about $0.056 million per MW, or roughly $55,600 per MW, for the right to build.
A figure like that is called a developer premium: the amount a buyer pays the original developer for taking a project through the risky early stages, separate from the cost of building it.
Why is the $72 million figure so different?
Because it measures something else. Ferrovial framed its first US renewable investment as totalling $72 million, while the annual report puts the price of the project company at $14.3 million. The share purchase is about a fifth of the stated total. The record does not break down what the remaining amount covers, and Enerdatics does not assume it.
The gap between the two numbers is the useful lesson. A headline investment figure and a transaction price answer different questions. The first tells you what a company plans to commit. The second tells you what the seller received. Only the second can be compared with other acquisitions.
The full cost of building a project like this is much larger than either. Enerdatics has covered two Texas utility-scale solar builds financed the same year: Primergy's Ash Creek loan, at about $1.44 million of debt per MWac, and the $1.09 billion package behind Vesper's Hornet Solar, at about $1.82 million per MWac. Development rights are a small slice of what a finished Texas solar plant costs.
Why did the price take so long to surface?
Because nobody had to publish it. Ferrovial's press release covered the project, the location and the expected output. It did not name Misae Energy or give a value. Enerdatics identified the seller and a deal value of about $14 million at the time, despite no public disclosure by either party. The annual report published later confirmed the figure at $14.3 million.
That pattern is common in US development-stage solar. Often, small developers sell project companies to larger builders, and the price only appears if the buyer's own reporting requires it.
Enerdatics' data shows 22 solar transactions involving under-development projects in Texas between January 2023 and June 2025, of which seven carry a disclosed value. Across the seven deals where a developer premium can be calculated, the median is about $0.05 million per MW, ranging from $0.04 million to $0.08 million. Ferrovial's $0.056 million per MW sits right at that median. Among ready-to-build projects alone, the three priced premiums run from $0.06 million to $0.08 million per MW, which places Ferrovial at the low end. A comparable 260 MW Texas project sold in July 2024 for $12.49 million, about $0.05 million per MW.
What does the deal signal for Texas solar M&A?
It signals that development-stage Texas solar trades at a narrow and fairly stable price for development rights. Seven priced premiums falling between $0.04 million and $0.08 million per MW over two and a half years suggests a market where buyers and sellers broadly agree on what permitting and grid positions are worth.
It also signals who the buyers are. Ferrovial is an infrastructure and construction group, and its agreement covers both building and operating the Leon County plant. The record notes that Ferrovial is also constructing a 72 MW solar plant with a 60 MW battery in Houston for X-Elio. A buyer that builds plants for others has a reason to own some itself: it captures the construction work and the long-term returns.
For small developers like Misae Energy, the model is clear. Take projects to ready-to-build, sell the project company, and leave construction risk to a larger balance sheet. For analysts, the lesson is to separate the purchase price from the investment headline. Ferrovial's $72 million and $14.3 million describe the same project. Only one of them is a deal value.
