TOKYO: Japan plans to temporarily relax restrictions on coal fired power plants as it grapples with an energy shortage triggered by the ongoing Middle East conflict, a government official confirmed on Friday.

The move will allow older and less efficient coal-fired plants to operate at full capacity for one year starting from the new fiscal year in April. Previously, power suppliers were required to limit the operating rate of such plants to 50% due to their high carbon emissions.

▶Japan to temporarily lift coal power plant curbs over Hormuz crisishttps://t.co/9yAGQCaDxQ

An official from Japan’s industry ministry said the proposal would be formally presented at an expert panel meeting later in the day. The decision reflects growing pressure on energy systems as global fuel supplies remain disrupted.
The crisis stems largely from tensions in the Middle East, where Iran has partially restricted traffic through the Strait of Hormuz, a critical route for global energy shipments. The disruption has significantly affected oil and gas flows, pushing countries to rely more heavily on alternative energy sources.
Japan, which depends on thermal power plants for about 70% of its electricity, uses coal as a major fuel source. While much of its oil imports come from the Middle East, the country sources nearly 80% of its coal from Australia and Indonesia, ensuring a relatively stable supply.
Other Asian economies are taking similar steps. South Korea is considering lifting caps on coal power while boosting nuclear energy production, and Philippines aims to increase coal output to stabilise electricity prices.

In addition to boosting coal use, Japan has begun releasing more of its strategic oil reserves to manage supply disruptions. The temporary policy shift highlights the difficult balance between energy security and environmental commitments as the crisis continues.
