Korean Tech Firms Directly Procure Renewable Energy for AI Data Centers

A significant and encouraging shift is underway in South Korea's IT sector, with major companies actively pursuing direct procurement of renewable energy to power their energy-intensive AI data centers. This proactive approach is driven by a dual objective: achieving the ambitious 'RE100' (Renewable Energy 100%) target and, crucially, lowering the long-term operational costs associated with these power-hungry facilities. This development is particularly noteworthy as it addresses the escalating electricity demands of the burgeoning AI industry while simultaneously accelerating the nation's transition to cleaner energy sources.

Naver's recent move marks a pioneering milestone. The company has entered into a power purchase agreement (PPA) with GS Wind Power and acquired a 30% stake in a wind farm in Yeongyang County, North Gyeongsang Province. This signifies the first instance of a domestic RE100 member directly investing in renewable energy generation to secure electricity supply. Under this agreement, Naver will receive power for its data centers in Chuncheon and Sejong for the next 25 years. This direct investment model offers a stable, long-term power supply for corporations and guarantees a consistent buyer for renewable energy developers, fostering a more robust green energy market.

Kakao has also embraced this trend, utilizing solar power for its data center in Ansan since early this year. The critical need for massive and stable power supplies for AI data centers is underscored by the fact that South Korea currently operates over 160 data centers, with more than 70 under construction. The PPA model not only ensures corporate energy security but also promotes the actual expansion of renewable energy capacity, moving beyond mere carbon credit purchases. This direct engagement is vital for accelerating the domestic renewable energy transition.

While PPAs may currently be 10-20% more expensive than industrial electricity rates from Korea Electric Power Corporation (KEPCO), and involve separate transmission fees, the economic landscape is rapidly shifting. With KEPCO's industrial electricity rates expected to rise annually and renewable energy costs continuing to fall, price competitiveness is anticipated to equalize within the next five to ten years. Furthermore, the imperative to transition to renewable energy is not merely a future aspiration but an immediate necessity. The government's updated electricity supply plan projects a significant increase in domestic power consumption over the next 15 years, largely driven by data centers and semiconductor factories. In an era of volatile fossil fuel markets, as evidenced by recent geopolitical tensions, and increasing international pressure through mechanisms like the EU's Carbon Border Adjustment Mechanism (CBAM) and global customer demands for carbon reduction, securing a stable supply of renewable energy is paramount for both economic sustainability and international competitiveness.
