In a significant shift for South Korea’s renewable energy landscape, major foreign investors are pulling out of the country’s offshore wind market, raising tough questions about the future of green energy development in the region. Over the past several years, global giants like Corio Generation—a subsidiary of Australia-based Macquarie Asset Management—Norway’s Equinor, and even the UK’s Shell have either scaled back their ambitions or exited altogether, citing a tangle of regulatory headaches, profitability woes, and persistent local resistance.
According to industry reports from M-Economy News and Namdo News, the most recent and high-profile departure came on March 31, 2026, when all employees of Corio Generation’s Korean branch, including CEO Choi Woo-jin, resigned en masse. This move effectively marked the completion of Corio’s withdrawal from the Korean offshore wind market—a decision that had been brewing for months. The company had initially announced an ambitious 1.3 trillion KRW investment plan in 2023, hoping to ride the wave of the Yoon Suk-yeol administration’s push for renewable energy. But the reality on the ground proved far less promising.
“Macquarie Asset Management has decided to wind down its offshore wind power business,” a Corio Generation spokesperson explained, as reported by M-Economy News. Despite having lined up a series of high-profile projects—including the 96 MW Dadaepo Offshore Wind Power project near Busan, a 600 MW fixed offshore wind farm near Maenggol Island in Jindo County, and a 500 MW floating wind project near Geomundo in Yeosu—Corio is now seeking buyers for its stakes. The Dadaepo project had even been selected in early 2025 as part of a public-led fixed offshore wind initiative, with construction just around the corner, but these plans have now been thrown into uncertainty.
Corio’s retreat is hardly an isolated case. The Norwegian state-owned energy giant Equinor, once a key player in Ulsan’s “Firefly” floating offshore wind project, has found itself sidelined after failing to secure a renewable energy certificate (REC) contract. This failure has led to a two-year ban on participating in domestic energy auctions, effectively stalling the project. Meanwhile, Singapore’s Equis is reportedly negotiating the sale of its Anma Offshore Wind project to Copenhagen Infrastructure Partners, hampered by unresolved military consultation issues with South Korea’s Ministry of National Defense.
Even Shell, the UK-based energy powerhouse, has pulled out of the Munmu Wind floating offshore wind project in Ulsan, selling its entire stake and leaving the field to others. The pattern is clear: foreign capital, once seen as the engine that would drive South Korea’s offshore wind boom, is now heading for the exits.
What’s driving this exodus? The answer, according to industry insiders interviewed by Namdo News, is a toxic mix of rising costs and regulatory gridlock. “The global offshore wind industry has deteriorated rapidly due to inflation-driven increases in material and construction costs, high interest rates raising capital costs, and supply chain instability,” one industry source told the paper. When Corio first entered the Korean market seven or eight years ago, the development cost per turbine was about 5 billion KRW. Today, that figure has ballooned to at least 8 billion KRW, squeezing profit margins to the breaking point.
South Korea’s unique regulatory environment hasn’t helped. Projects often face fierce local opposition, especially from fishing communities worried about their livelihoods. Add to that the thorny issues of military operation zones, shipping lanes, and a labyrinthine permitting process involving multiple government agencies, and it’s no wonder that some projects have languished for more than six years without breaking ground. “From the perspective of foreign companies, it’s hard to understand or endure that Korean projects started seven or eight years ago haven’t even begun construction, while projects in Taiwan or Japan that started later are already up and running,” the same industry insider remarked.
The government has tried to respond, most notably with the recent enactment of the Offshore Wind Power Special Act. This law aims to streamline project approvals and shift the industry towards a government-led site planning model, with the hope of shortening notoriously long preparation periods. However, the law won’t come into force for another year, and its immediate impact on existing projects—already bogged down by permit, local acceptance, and grid connection issues—is expected to be limited.
Some officials and experts see a silver lining in this foreign exodus. Park Sook-hee, head of South Jeolla Province’s Offshore Wind Industry Division, told Namdo News, “With the enactment of the Offshore Wind Power Special Act, the government will take the lead in developing wind farms. So, when foreign companies leave, we can simply convert those areas to government-led planned sites. We’re not too worried.” She added that large-scale foreign developers, those working on 1-2 GW projects, are less likely to withdraw and may even benefit from the opportunity to secure scarce transmission capacity as public projects ramp up.
Yet, skepticism remains about whether these opportunities will be enough to offset the loss of foreign expertise and capital. The Korean market’s challenges—long project timelines, uncertain profitability, and a sometimes-hostile regulatory climate—are not easily solved. Even as the government doubles down on its renewable energy ambitions, the ground reality is that investment is drying up, and the sector is at a crossroads.
For now, the fate of South Korea’s offshore wind industry hangs in the balance. The government’s new legal framework may eventually smooth the way for more public-led development, but the immediate future looks rocky. As foreign investors pack up and leave, the question remains: will Korea’s homegrown efforts be enough to fill the void, or will the country’s green ambitions stall just as they were picking up speed?
Only time—and perhaps a few bold policy moves—will tell whether South Korea can turn this moment of uncertainty into a new era of renewable energy leadership.
