Hokkaido Electric Power will not be able to provide stable power supply in the winter unless the nuclear power plants are restarted nightly Ali announced

In the summer of this year, the electric power company in each region will lack supply reserve for demandCall for energy conservation cooperation, 10% in the Kansai Electric Power Company and Kyushu Electric Power Company, 7% in the Hokkaido Electric Power Company, and 5% in the Shikoku Electric Power Company as power saving targets.

So far, power saving has been effective in all areas, but according to the information Hokkaido Electric Power announced on July 31, this year'sWinter power supply and demandIf there is no chance of restarting the currently stopped Night Nuclear Power Plant, it is impossible to secure the minimum necessary reserve ratio for operation and there is a risk that stable power supply will not be possible.

HEPCO: On electricity supply and demand in this winter

According to Hokkaido Electric Power Co., this summer measures such as adjusting the repair timing of the power generation equipment to secure stable supply, extending the operation time of the pipeline so that the fuel of the thermal power plant can be delivered for 24 hours He said he was working on it. On the other hand, in consideration of the maximum demand in FY 2010, which was extremely hot, in order to have supply reserve capacity of 150,000 kW (equivalent to 3%) for supply capacity of 4.48 million kW, we requested more than 7% power saving It was.

As a result, the average demand from June to July is 240,000 kW compared with FY2011, which is 360,000 kW lower than in FY2010.


However, the demand of Hokkaido's electricity demand has increased since November,It will peak in the year from December to FebruaryThat place. Honshu uses peak air conditioners in the summer but in Hokkaido, the demand for heating is large, on the contrary.

In addition, if it is summer, you can shift the peak by stopping the factory operation in the daytime, but in the winter it is cold so snow melting is necessary on the night to heat up, so the peak I can not shift it. The peak itself is also about 700,000 kW higher than in the summer.

Supply power of January 2013 estimated by Hokkaido Electric Power Co. is 5.84 million kW. Even this, the supply capacity of the hydropower and thermal power supply has been increased by 1 million kW due to the supply power of the summer, but compared with the January 2012 (6.5 million kW) Night Nuclear Power Plant Unit 3 was operating It will decrease by 660,000 kW.

As a countermeasure against this shortage, we are currently considering deferral of inspections of multiple power plants by special measures, but even though the supply reserve ratio from December to February still falls below 2%, which is the minimum necessary 3% It is said that there is a possibility.

In addition to the above, we plan to suspend unplanned power generation facilitiesHokkaido-Honshu interconnection equipmentAlthough it seems that it is possible to stop such as Northern Electric Power Co., it seems to work on countermeasures such as additional installation of emergency installation power supply and further procurement of fuel, but if nuclear power plants do not operate again, this winter will be tough, is summarized .
