Tokyo, April 12 (Jiji Press)–The electricity supply situation in Japan will be the tightest since fiscal 2012 in February next year if the winter is severely cold, the industry ministry said Tuesday.


The “reserve ratio,” which indicates the margin of electricity supply capacity over demand, will fall below 3 pct, the minimum level required for stable supply, in January and February in seven regions, including Tokyo, the ministry said.


From July to September, the reserve ratio will be 3 pct or higher in all regions even if the heat is severe, the ministry said.


But the ratio is estimated at minus 1.7 pct in January and minus 1.5 pct in February in the Tokyo region under a severely cold weather.


The ratio is forecast to range between 2.2 pct and 2.5 pct during the winter period in the remaining six regions.


In the face of the severe outlook, the ministry will take steps to increase electricity supply, including inviting applications for additional supply.


Japan has announced plans to phase out Russian coal imports as part of sanctions on Moscow over its invasion of Ukraine, a setback for thermal power plans that play a key role in addressing tight electricity supply.


It is unclear whether Japan can supply electricity stably by reducing its dependency on Russian coal and finding a substitute supplier.
