Energy – Japan Considers Temporary Expansion of Coal Power Use Amid Fuel Uncertainty
Energy – Japan is preparing to ease restrictions on coal-fired power generation as authorities respond to mounting concerns over energy security linked to geopolitical tensions in the Middle East. The move, discussed and approved by a government-appointed expert panel, reflects growing uncertainty surrounding fuel imports, particularly liquefied natural gas.
Government Moves to Strengthen Energy Stability
During a recent policy meeting, officials from the industry ministry highlighted the increasing risks associated with fuel procurement. They pointed to disruptions in global supply chains and rising prices as key factors driving the decision. According to the ministry, boosting coal power usage is seen as a necessary step to maintain a stable electricity supply in the near term.
The proposal allows for expanded operations at coal-fired power plants, including older facilities that had previously been limited due to environmental concerns. Authorities believe this temporary adjustment will help bridge potential gaps in energy availability.
Relaxation of Operational Limits
Until now, Japan had capped the operating capacity of coal-based thermal power plants at 50 percent, mainly to curb carbon emissions. Under the revised plan, these limits will be lifted for a one-year period starting from the new fiscal year in April. This includes permitting full utilization of less efficient plants that were previously restricted.
Officials estimate that this measure could significantly reduce reliance on liquefied natural gas, potentially saving around 500,000 tons of LNG during the period. The move is being framed as an emergency response rather than a long-term policy shift.
Heavy Dependence on Imported Energy
Japan’s energy mix remains heavily dependent on thermal power, which accounts for roughly 70 percent of total electricity generation. Coal and LNG each contribute about 30 percent to this share, while oil makes up a smaller portion.
The country relies heavily on imports to meet its energy needs. More than 90 percent of its oil supply comes from the Middle East, making it particularly vulnerable to disruptions in that region. Additionally, around 10 percent of LNG imports also originate from Middle Eastern sources.
Coal imports, however, are more diversified, with nearly 80 percent sourced from Australia and Indonesia. This relative stability in coal supply is one of the reasons the government is turning to it as a short-term solution.
Regional Shift Towards Coal Usage
Japan’s decision aligns with a broader trend across Asia, where several countries are increasing reliance on coal to offset uncertainties in gas supplies. The ongoing conflict in the Middle East has impacted critical energy routes, including the Strait of Hormuz, leading to concerns over supply continuity.
Other nations in the region have taken similar steps. South Korea is considering lifting restrictions on coal power generation while also enhancing nuclear output. Meanwhile, the Philippines is planning to boost coal-based electricity production to manage rising energy costs.
Strategic Reserves and Future Outlook
In addition to adjusting power generation policies, Japan has also begun releasing portions of its strategic oil reserves to mitigate supply challenges. This step underscores the seriousness of the situation and the government’s intent to ensure uninterrupted energy access.
While the increased use of coal may raise environmental concerns, officials emphasize that the measure is temporary and driven by immediate necessity. The government is expected to continue monitoring global energy markets and adjust its strategy accordingly.
The decision reflects the delicate balance Japan must maintain between energy security and environmental commitments, particularly during periods of global instability
