South Korea's 2040 power demand forecast up 7-11% from previous estimates

The Hankyoreh reports on a critical juncture for South Korea's energy future. The Ministry of Trade, Industry and Energy, along with the 12th Electricity Supply and Demand Plan Committee, has released preliminary projections for 2040, indicating a substantial rise in national electricity consumption and peak demand. This upward revision, 7-11% higher than previous estimates, signals a significant challenge in securing adequate power generation and transmission infrastructure over the next 15 years.

The core of this increased demand stems from the accelerating pace of electrification across various sectors, from transportation to industrial processes. Furthermore, the rapid proliferation of AI data centers and the continued expansion of the semiconductor industry are major contributors. While these sectors represent technological advancement and economic growth, they place immense pressure on the nation's power grid. The committee's breakdown reveals that electrification alone accounts for a substantial portion of the projected additional demand, underscoring the transition away from fossil fuels towards electricity as a primary energy source.

“

Although additional demand in the electrification sector has increased significantly, fossil fuel demand has also decreased considerably, so overall energy demand is decreasing. The problem is, what will be used to produce the electricity resulting from electrification? We need to rapidly increase production from renewable energy, not conventional production using nuclear power, LNG, or coal. In addition, we should consider increasing electricity rates to help reduce power demand and increase consumer-side power generation (BTM).

Discussions are already underway regarding how to meet this burgeoning demand. Experts like Lim Jae-min of the Energy Transition Forum emphasize the need for a rapid increase in renewable energy sources, such as solar and wind power, to supplement traditional generation methods like nuclear, LNG, and coal. He also suggests exploring electricity pricing mechanisms that encourage demand reduction and the growth of distributed energy resources. This highlights a key debate within South Korea: balancing the need for increased energy supply with the urgent imperative to transition to sustainable, renewable sources.

Kim Gyu-won, a senior reporter at The Hankyoreh, points out the spatial implications of these projections. The concentration of increased demand in areas with data centers and semiconductor industries raises questions about regional development and infrastructure investment. He advocates for a decentralized energy system, suggesting that relocating these industries to provincial areas could not only reduce the immense costs associated with national grid expansion but also accelerate the adoption of regional renewable energy. This approach could mitigate social conflicts arising from centralized infrastructure and foster more equitable development across the country. From our perspective, this is not just about megawatts and gigawatts; it's about shaping a sustainable and equitable energy landscape for all Koreans.

The committee plans to establish regional demand forecasts linked to the grid plan. Looking at the current forecast, the location of data centers and semiconductor industries, where additional demand is concentrated, seems important. If these industries are relocated to provincial areas, a significant portion of the 78 trillion won in grid costs can be reduced, and provincial renewable energy generation can be rapidly increased. The power grid can also be made more efficient with a decentralized system rather than a centralized one, reducing social conflict. Regional electricity demand plans should be established in this direction.
