SK launches South Korea's largest renewable energy firm, targets sixfold capacity expansion by 2031

SK Group is teaming up with private equity firm KKR to launch South Korea's largest renewable energy company, with plans to expand the combined entity's power capacity sixfold to 10 gigawatts by 2031.

SK announced Tuesday that it has signed an equity investment agreement with KKR-managed funds for an integrated renewable energy holding company. SK Innovation, SK Ecoplant and SK Discovery are currently selling their respective renewable energy assets to KKR through business and equity transfers. The integrated entity, tentatively named HoldCo, is set to officially launch by the end of this year.

KKR will hold a 51 percent stake in the new company, with SK retaining 49 percent. KKR will hold initial management control, though SK has left open the possibility of acquiring that control through future negotiations after joining as an equity investor.

KKR, which is co-investing in the venture, is widely regarded as one of the world's leading investors in renewable energy. The firm manages more than $100 billion in infrastructure assets and has invested more than $31 billion in renewable energy infrastructure since 2011.

The core rationale behind the consolidation is to bring together SK Group's scattered renewable energy operations under one roof, achieving economies of scale and operational efficiency at the same time. The new entity will cover the full spectrum of renewable power generation — solar, offshore and onshore wind, fuel cells and energy storage systems — excluding hydrogen. The move consolidates assets that had been subject to overlapping investment and fragmented management across affiliates.

The integrated entity currently operates about 1.7 GW of power capacity, which it plans to grow to 10 GW by 2031 — the largest scale in South Korea. That target capacity is enough to simultaneously power 100 large-scale data centers rated at 100 megawatts each without interruption. If achieved, the company is expected to become a key source of clean power for AI data centers and global semiconductor production lines.

The decision was driven by the need to improve investment efficiency in the renewable energy business. SK expects capacity scale-up and development of new power sources to require sustained large-scale investment. Relying solely on individual affiliates to raise funds through their own borrowing or share issuances would place a significant financial burden on each. SK concluded that co-investing with strategic capital partners was the more efficient alternative.

The partnership with KKR is also expected to generate business synergies. Through the investment, SK will be able to tap KKR's global renewable energy assets and network to identify overseas opportunities. Combined with cost reductions from consolidated equipment procurement and the benefits of scale, the integrated entity's profitability and competitiveness are expected to improve further.

"South Korea is one of the most attractive renewable energy markets in Asia, with robust corporate demand for clean power across semiconductors, data centers and manufacturing broadly," said Kim Yang-han, KKR's head of infrastructure for Northeast Asia. "Through this partnership, we will build a large-scale renewable energy platform capable of reliably meeting the high power demands of South Korea's industrial sector."

An SK official said the consolidation was "part of a preemptive portfolio rebalancing to strengthen the sustainability and competitiveness of the business," adding that the company would "combine KKR's financial firepower with SK's execution capabilities to meet rapidly growing clean energy demand and build a long-term, sustainable growth model."
