Introduction to the RE100 Initiative
On July 10, a significant plan was introduced to create special legislation aimed at developing industrial complexes and energy cities powered entirely by renewable energy. This initiative, known as “RE100,” represents the first comprehensive industrial policy under the current administration. The goal is to establish manufacturing hubs in regions with abundant solar and wind resources, such as South Jeolla Province and Ulsan. These areas will be equipped to operate solely on renewable energy, which is expected to reduce the concentration of electricity demand in the Seoul metropolitan area and provide a foundation for revitalizing local economies.
Strategic Goals and National Policy Alignment
The RE100 initiative aligns with the president’s core national policy goals of achieving an “energy transition” and “balanced regional development.” It reflects a broader strategy to shift towards sustainable energy sources while addressing economic disparities across different regions. As global corporations increasingly demand that their suppliers meet RE100 commitments—requiring the use of 100 percent renewable energy—South Korean exporters must adapt to maintain their competitiveness in the international market.
Legislative and Financial Challenges
To support this initiative, the government plans to pass the special law within the year. President Lee has also instructed officials to review a range of incentives for participating companies, including substantial reductions in electricity rates. However, one of the central challenges is whether the government can supply renewable energy at competitive prices. The generation cost for renewables remains significantly higher than other sources, posing a financial challenge for both the government and energy providers.
As of May, Korea Electric Power Corporation (KEPCO) was purchasing solar power at 130.5 won per kilowatt-hour (kWh) and wind power at 123.6 won per kWh—both about 1.5 times more expensive than nuclear power, which costs 80 won per kWh. Energy experts warn that this price disparity could lead to electricity rate increases or further strain KEPCO’s already fragile financial position.
Financial Strain on KEPCO
With debt levels exceeding 200 trillion won, any continued obligation to sell electricity below cost would deepen the utility’s deficits. Recent amendments to the Commercial Act, which reinforce fiduciary duties to shareholders, have intensified the dilemma for KEPCO. As of the end of March, KEPCO’s debt stood at 206.8 trillion won ($148 billion). The company spent 4.67 trillion won ($3.3 billion) on interest payments in 2024 and has already paid 1.12 trillion won in the first quarter of 2025.
Despite returning to profitability in 2024 for the first time in four years—with an operating profit of 3.2 trillion won ($2.3 billion)—KEPCO posted an additional 1.9 trillion won ($1.4 billion) in operating profit during the first quarter of 2025. However, its accumulated losses still exceed 30 trillion won ($21 billion).
Infrastructure and Shareholder Concerns
If the government proceeds with RE100 industrial complexes, KEPCO is likely to face significant cost burdens. The company has previously recorded major deficits due in part to the high costs of renewable energy procurement. In addition, the construction of a large-scale power transmission network will be essential, as most renewable power plants are located in provincial areas while electricity demand remains concentrated in the capital.
Analysts anticipate that KEPCO will also be responsible for funding this infrastructure expansion. The Lee administration’s recent revision to the Commercial Act adds further pressure. The law, now in effect, holds corporations to stricter shareholder accountability. With individual investors holding 36.83 percent of KEPCO’s shares, the company is likely to face growing shareholder resistance if RE100-related costs worsen its financial standing.
Investor Reactions and Economic Implications
While KEPCO’s stock price, which fell below 20,000 won earlier this year, had rebounded to the 37,000-won range in early July, it has since declined following the RE100 announcement, reflecting investor concerns over the potential financial impact.
Experts acknowledge that RE100 industrial complexes are a necessary response to alleviate the capital region’s electricity concentration and address regional economic imbalances. However, they point out that the initiative still lacks public consensus and a detailed fiscal roadmap. Yoo Seung-hoon, a professor at Seoul National University of Science and Technology, emphasized the need for a structured approach to avoid placing excessive burden on KEPCO. He proposed financing support for tenant companies through the electric power industry basis fund or having local governments reinvest a portion of increased tax revenue generated from business attraction into the industrial complexes.
