Actis has paid $100 million for Argo Energy, a four-year-old South Korean solar developer, in its first investment in the country's renewable energy sector. The platform counts 110 MW of projects in operation or advanced development. Enerdatics understands that only about 6 MW of that is running.
Key takeaways
- Actis announced on 27 March 2024 that it had acquired Argo Energy, a solar power platform based in Seoul, for a consideration of $100 million, its first investment in South Korea's renewable energy sector.
- Argo Energy has 110 MW of solar projects in operation or advanced development, and Enerdatics understands from the seller's website that about 6 MW is operational and 104 MW is under development.
- Actis aims to own 100 percent of Argo Energy and targets a contracted portfolio of more than 400 MW in the coming years, with power sold under corporate PPAs.
- The $100 million Actis paid for Argo Energy equals about $0.91 million per MW across the 110 MW portfolio, or about $0.25 million per MW across the 400 MW target.
- Enerdatics records only two South Korean solar M&A transactions from January 2023 to June 2025: Actis' purchase of Argo Energy and BlackRock's $78 million follow-on investment in Brite Energy Partners.
What does Argo Energy actually own?
Mostly projects that are still to be built. Argo was established in 2020 and works in small utility-scale and rooftop solar in Korea. It has four lines of business: developing solar projects with local developers and landowners, acquiring solar assets at any stage, rooftop generation and agricultural solar, where panels share land with farming.
The operating fleet is small. Enerdatics understands, based on the seller's website, that about 6 MW is operational. The examples Leap records are a 2.2 MW farm in Bonghwa, operating since December 2022, and two 0.4 MW farms in Andong and Gimcheon that started in 2022.
The pipeline carries the weight. Enerdatics understands that 104 MW is under development, including a 32 MW farm in Ulsan expected to operate in the fourth quarter of 2024, a 16 MW farm in Bonghwa expected in the fourth quarter of 2025, and a 14 MW farm in Taean expected in the second quarter of 2026. On those figures, about 95 percent of the 110 MW had not yet been built when Actis bought in.
What is Actis paying for at $100 million?
A route into a market, more than a set of assets. Leap stores the deal at $0.91 million per MW, which divides the price by the full 110 MW. That figure treats the whole 110 MW as if it were generating, and most of it is not. Measured against the roughly 6 MW Enerdatics understands to be running, the price works out at more than $16 million per operating MW, a figure that only makes sense if the pipeline is what is being bought.
The more useful denominator is the target. Actis says it aims to grow Argo's contracted portfolio to more than 400 MW. Across that figure the price falls to about $0.25 million per MW. The gap between the two numbers is what Actis is betting on: that a local team with land relationships and a development record can turn a small fleet into a platform four times its size.
The route to market supports that. Argo sells power through corporate PPAs, long-term contracts with companies that want renewable electricity. That gives each new project a buyer before construction rather than relying on wholesale prices. Actis has said it intends to own 100 percent of the platform, which keeps the build-out under one owner.
Actis has built and sold a platform before, as with BTE Renewables, the African wind and solar platform it agreed to sell to ENGIE and Meridiam. Argo fits its Asia Climate Strategy, which Actis describes as aimed at accelerating the climate transition and reducing carbon emissions in Asia.
Enerdatics' data shows 30 South Korean renewable energy M&A records from January 2023 to June 2025. Twenty-two of them are joint ventures or development partnerships, mostly in offshore wind and hydrogen. Only seven carry a disclosed value. Solar accounts for two: Actis' $100 million purchase of Argo Energy and BlackRock's $78 million investment in Brite Energy Partners in July 2024, its fourth investment in that Korean solar producer. The Brite deal was growth capital for a company that already operates more than 300 solar plants, so it is not a like-for-like comparison. That leaves Argo as the only disclosed price for control of a Korean solar platform in the period.
The other priced Korean deals are offshore wind development stakes, and they sit at a fraction of Argo's per MW figure once grossed up to 100 percent. BP's 55 percent of four projects totalling 6 GW for $70 million implies about $0.02 million per MW. B.Grimm's 49 percent of a 740 MW portfolio for $61.03 million implies about $0.17 million per MW. Those are seabed and permits, years from revenue. Argo's price reflects projects much closer to construction, with a contracting model already in use.
What does the deal signal for Korean solar?
It shows that foreign capital entering Korean solar is buying teams, not megawatts. The Korean solar assets in these records are small. Brite Energy Partners operates more than 300 plants, and the examples Leap lists range from 2.7 MW to 13.5 MW. Argo's development projects run from 14 MW to 32 MW. A foreign investor would struggle to assemble that kind of portfolio from abroad without a local developer that already has the land, the permits and the relationships.
It also shows how thin the price evidence is. With two solar deals in two and a half years, and one of them a follow-on growth round, any benchmark for Korean solar rests on Argo alone. The market has also attracted project-level capital, such as the financing for the Shinan salt farm solar project, but corporate deals remain rare.
The test is the build-out. If the Ulsan, Bonghwa and Taean projects reach operation on schedule, Argo's operating fleet would grow from about 6 MW to more than 60 MW. That would bring the price per operating MW down sharply and show whether Actis paid for the pipeline at the right time.
