Electricity Supply & Demand Report for December 2012 1. Electricity demand (See Table 1)
Electric power sold in December totaled 6,728 GWh, which was 103.2% as compared with the same period of the previous year. This was because of a rebound in sales after the impact of the Great East Japan Earthquake and the lower temperature, resulting in a higher demand for heating. It exceeded the results of the previous year for 10 consecutive months.
Electric power sold in the previous year was significantly decreased by the Great East Japan Earthquake, so for your information, the comparison of the year before last year is also shown in Table 1.
- Non-Specified Scale Demand (Excluding deregulated segment)
Due to a demand for earthquake disaster reconstruction and a higher demand for heating because of the lower temperature, power demand in the lighting (residential) sector was 104.8% as compared with the same period of the previous year, and which exceeded the result of the previous year for 5 consecutive months.
Non-specified scale demand in total was 105.1% of the same period of the previous year.
- Specified Scale Demand (Deregulated segment)
Due to a rebound in sales after the impact of the Great East Japan Earthquake and a higher demand for heating because of the lower temperature, electric power sold for commercial use was 107.0%
year-on-year. It exceeded the results of the previous year for 10 consecutive months.
Overall power demand in the specified-scale sectors totaled 101.9% of the same period of the previous year.
In the industrial and other sectors, power demand mostly came from large-scale industrial customers, as described in the reference below.
[Reference]
- Large-scale industrial demand
Large-scale industrial demand in total was 98.9% year-on-year. Due to a low operating rate mainly at export-oriented companies by the slowdown in overseas economy, large-scale industrial demand fell behind the performance of the previous year for 2 consecutive months.
Electricity generated and purchased in December totaled 8,018 GWh, 102.5% as compared with the same period of the previous year, and it has exceeded the performance of the previous year for 11 consecutive months.
Electricity generated and purchased in the previous year was significantly decreased by the Great East Japan Earthquake, so for your information, the comparison of the year before the last year is also shown in Table 2.
(Power generated by our own hydro power stations) The flow rate was 72.8% during this period.
Since hydro power stations had been shut down last year because of the heavy rainfall in Niigata and Fukushima, hydropower generation totaled 406 GWh, an increase of 3 GWh from the same period of the previous year.
(Power generated by our own thermal power stations)
Due to the increase of the purchased power, generated output totaled 5,289 GWh, an increase of 137
GWh from the same period of the previous year.
(Power generated by our own nuclear power stations)
All units of Onagawa nuclear power station and unit 1 of Higashidori nuclear power station have been shut down because of regular inspection, so there was no nuclear power generation.
(Power generated by our own renewable power stations)
Since operation of geothermal power stations was different from that of the same period of the previous year, generated output totaled 64 GWh, a decrease of 36 GWh, year-on-year.
(Power purchased)
Due to shutdown of power stations caused by the Great East Japan Earthquake last year, total power purchased from others totaled 2,481 GWh, an increase of 497 GWh from the same period of the previous year.
