South Korea's Energy Transition Amid the Iran Crisis

In response to the ongoing Iran crisis, South Korea is accelerating its transition to renewable energy, exemplified by the solar initiative in Guyang-ri, a village south-east of Seoul. This one-megawatt solar installation generates approximately 10 million won ($6,800) monthly, funding communal meals and local welfare projects. The village's chief, Jeon Joo-young, emphasizes that the solar revenue fosters community bonds, contrasting the previous lack of infrastructure. This project is part of a broader government initiative to establish 2,500 "solar income villages" by 2030, with a target of 700 villages for this year alone.

President Lee Jae Myung has framed the energy transition as crucial for national security, given that over 90% of South Korea's energy is imported, primarily through the Strait of Hormuz. The government aims to generate 20% of its electricity from renewables by 2030 and phase out coal by 2040. A supplementary budget of 500 billion won has been allocated to support this transition, alongside 400 billion won in low-interest loans for solar projects in other villages.

Despite these ambitious goals, South Korea's renewable energy programs face significant challenges. The electricity grid, particularly in the southern regions where solar and wind development is concentrated, is nearing capacity limits. Many renewable projects are stalled due to the grid's inability to accommodate additional capacity. Energy economist Hong Jong Ho notes that the Korea Electric Power Corporation (Kepco) maintains artificially low electricity prices, which discourages investment in renewable infrastructure. This long-standing practice has led to public resistance to the costs associated with transitioning to renewable energy.

Moreover, South Korea's reliance on Chinese supply chains for solar panels poses additional risks. The government has introduced measures to promote domestic solar module production and carbon footprint certification for imports, but critics argue these efforts are insufficient.

The Iran crisis has exacerbated South Korea's economic vulnerabilities, with the OECD lowering the country's growth forecast by 0.4 percentage points—the largest reduction among major economies. The nation, heavily dependent on energy imports, faces a "triple shock" of high inflation, elevated interest rates, and a declining won. As of late March 2026, 26 South Korean vessels were stranded in the Persian Gulf, disrupting critical supply lines for raw materials and fuel.

The government has responded with emergency measures, including a $17 billion supplemental budget and fuel price caps for the first time since 1997. However, these actions have raised concerns about the sustainability of the energy transition, as significant funds are still directed toward absorbing fossil fuel price hikes.

Environmental groups, such as Solutions for Our Climate, acknowledge the government's intent to accelerate the energy transition but express skepticism about its execution. Gahee Han from the group highlights the contradiction of a government suppressing energy prices while urging conservation. The ongoing reliance on coal and nuclear energy, alongside delayed plant closures, raises questions about the government's commitment to transformative change.

The future of South Korea's energy landscape hinges on whether the government can navigate these challenges effectively. The current geopolitical crisis presents an opportunity for significant reform, but the institutional mindset that favors fossil fuel stability remains a barrier to progress.
