In a recent statement, Kyushu Electric Power has announced the temporary shutdown of the Sendai 1 nuclear reactor, starting June 14, and to implement preventive maintenance work. This process will take approximately three months and is part of the plant’s regular maintenance activities.
Scheduled maintenance of the Sendai 1 nuclear reactor
The reactor, located in Kagoshima Prefecture in southern Japan, will be shut down for routine maintenance work. According to the notice issued by the Japan Electric Power Exchange, the reactor is expected to begin test generation in the final stage of repairs on August 29. Kyushu Electric Power plans to complete the entire recovery process by September 25.
However, the absence of the Sendai 1 reactor will not negatively impact the Kyushu region’ s power supply during high summer demand, which generally extends from July to September. The company will continue to operate its other three nuclear reactors during this period to ensure a constant supply of energy.
On the other hand, Kyushu is estimated to maintain a power supply surplus of more than 13% during the months of July through September, well above the minimum 3% reserve needed to handle unforeseen emergencies such as an unexpected plant shutdown or an increase in peak electricity demand.
Nuclear capacity and LNG demand
The maintenance target is to expect Kyushu’s nuclear operating capacity during July through September to average 3,388 MW. This potential reduction in nuclear nuclear production could increase liquefied natural gas (LNG) demand by approximately 162,200 tons, equivalent to 2-3 standard large cargoes, during the quarter, assuming an average gas-fired generation efficiency of 50%.
