Equinor agreed in July 2023 to buy Rio Energy, a Brazilian wind and solar developer, from Denham Capital. Equinor's 2023 annual report later put the price at $350 million, and showed that only $82 million of it was paid for the shares. The rest went somewhere else, and so did the larger half of Rio Energy's operating fleet.
Key takeaways
- Equinor agreed on 21 July 2023 to acquire 100% of Brazilian renewables developer Rio Energy from Denham Capital, and the transaction completed on 6 November 2023.
- Equinor's 2023 annual report puts the total consideration for Rio Energy at $350 million, made up of $82 million in cash for the 100% stake and $268 million contributed to settle Rio Energy's external financing.
- Equinor took over the 223.25 MW Serra da Babilonia 1 onshore wind farm in Bahia, which began operating in 2018, plus about 0.6 GW of advanced-stage solar PV and about 1.2 GW of onshore wind and solar pipeline.
- Denham Capital kept about 1.1 GW of Rio Energy's assets, including about 0.5 GW of operating wind at Caetite, Itarema and Serra da Babilonia 3 and the 0.2 GW Caetite Norte wind project under construction.
- Across the roughly 2,023 MW Equinor acquired, the $350 million consideration equals about $0.17 million per MW.
What did Equinor actually buy from Denham Capital?
Equinor bought the company and a selected slice of its assets, not the whole portfolio. Before the deal, Rio Energy had about 830 MW in operation across three wind complexes and about 1.5 GW in development. The transaction split that portfolio in two.
Equinor got the corporate shell, the team of about 140 employees and its management, one operating wind farm and most of the development pipeline. Rio Energy continues as a wholly owned Equinor subsidiary and keeps advancing the projects it now holds.
Denham got to keep most of the operating fleet. Its retained 1.1 GW includes the bulk of the built wind capacity, the Caetite Norte project still under construction and about 0.4 GW of pipeline. Denham said it would set up a new management team for those assets and planned to bring them to market in 2025.
So the buyer took the platform and the growth, and the seller kept most of the cash flow. That is an unusual way to divide a developer, and it shapes how the price should be read.
Where did the other $268 million go?
It went to Rio Energy's lenders, not to Denham. Enterprise value is the price of a company's equity plus the debt that comes with it. When a buyer pays off a target's borrowings at closing, that money counts toward the deal value but never reaches the seller.
That is what happened here. Equinor paid $82 million in cash for 100% of the shares and contributed $268 million to settle Rio Energy's external financing. The headline $350 million is therefore an enterprise value, and more than three quarters of it cleared debt.
The figure was not in the deal announcement. Enerdatics identified the $350 million value even though neither party disclosed it in the transaction press release, and Equinor's 2023 annual report then confirmed it.
How much of the price does the operating wind farm explain?
Probably most of it. Serra da Babilonia 1 is the only operating asset Equinor received. It holds a 20-year PPA awarded in 2015 through Brazil's Chamber of Electric Energy Commercialization, the CCEE. A power purchase agreement, or PPA, is a long-term contract to sell a plant's output at an agreed price. Equinor's trading arm, Danske Commodities, will handle the power the farm generates.
Operating, contracted wind farms in Brazil have changed hands at prices around $1 million per MW in recent years. If the 223.25 MW farm were valued in the range set by those sales, it alone would account for between about $192 million and about $297 million. That is simple arithmetic on the comparables below, not an Enerdatics valuation of the asset.
On that reading, Equinor paid relatively little for the 1.8 GW of solar and wind it is still developing. That fits a pattern in development-stage deals. Pipeline is cheap because most early-stage projects never get built, and buyers pay mainly for what is operating or close to it.
Enerdatics' data shows how wide that gap is in Brazil. Across 32 Brazilian wind M&A transactions Enerdatics records from 2022 to 2024, only 12 carry a disclosed value. The priced sales of operating wind assets cluster between $0.86 million and $1.33 million per MW: AES acquired 456 MW from Cubico for $393.52 million in August 2022, Copel acquired 260.4 MW from EDP for $346.72 million in October 2022, and Statkraft acquired the 260 MW Jerusalem and Boqueirao farms from EDP for $320.2 million in August 2023. Development-stage wind sold for a fraction of that. AES paid $8.77 million for 305 MW from Renova Energia in January 2022, and ENGIE paid $53.6 million for 882 MW from PEC Energia in May 2022, both under $0.07 million per MW. Equinor's blended $0.17 million per MW sits between the two groups, which is what a deal mixing one operating farm with a large pipeline should look like.
What does the deal signal for Brazil's renewables market?
It signals that international buyers want Brazilian platforms with teams attached, not just megawatts. Equinor said the acquisition fits its strategy of growing onshore renewables in Brazil through regional companies with strong teams and projects. Keeping all 140 Rio Energy staff was part of the point. Enerdatics has also tracked how Equinor manages its other Brazil solar ties.
It also shows how financial sponsors exit. Denham did not sell everything at once. It sold the development engine to a strategic buyer that could fund it, kept the operating assets that produce steady income, and set them up for a separate sale. That is a common sequence as Brazilian buyers move toward full platform takeovers.
For Equinor, Rio Energy was one of several moves into new low-carbon businesses that year. A month later it bought into a Texas carbon storage hub, in the Bayou Bend CCS project.
The advisers were mostly on the sell side. Itau BBA and Bank of America Merrill Lynch Banco Multiplo advised Denham on financial terms, with Sidley Austin and Lefosse Advogados on legal terms. Mattos Filho acted as legal adviser to Equinor.
