Massive fire at South Korean energy storage facility exposes safety risks amid renewable push

A massive fire broke out at an energy storage system (ESS) facility in Gangjin, South Jeolla, in March 2025. Despite a rapid response from 123 firefighters and 31 fire engines, the blaze could not be contained. This incident follows a long history of ESS fires in South Korea, raising concerns about safety as the country pushes for more renewable energy.

The first major ESS fire in South Korea occurred in Gochang, North Jeolla, in August 2017. That incident destroyed 3,852 battery modules worth over 10 billion won ($6.4 million) in just 10 hours. Since then, 30 more ESS fires have been reported across the country over two years and five months, causing nearly 89 billion won in damages.

ESS facilities play a crucial role in renewable energy by balancing the unpredictable supply from solar and wind power. However, lithium-ion batteries, commonly used in these systems, have a critical flaw: a thin separator membrane that can fail, leading to thermal runaway and fires. The Ministry of Climate, Energy and Environment has ambitious plans to expand solar and wind capacity to 100 gigawatts by 2030. It also aims to increase renewable electricity generation to over 30 percent by 2035, with a projected investment of 268 trillion won.

The latest fire in Gangjin highlights ongoing safety challenges for ESS facilities. As South Korea accelerates its renewable energy expansion, ensuring the stability of energy storage systems remains a key issue. The ministry’s targets depend on addressing these risks effectively.
