Electricity Supply & Demand Report for June 2014 1. Electricity demand (See Table 1)
Electric power sales in June totaled 5,745 GWh, which was 99.8% as compared with the same period of the previous year. The sales were below the results of the previous year for two consecutive months due to our customers' power-saving efforts and other factors, even though a post-quake reconstruction continued.
Sales by customer segment were as follows:
- Non-Specified Scale Demand (Excluding deregulated segment)
While the post-quake reconstruction continued, power demand in the lighting (residential) sector was
98.7% year-on-year due to our customers' power-saving efforts and other factors, and which fell below the results of the previous year for two consecutive months.
Non-specified scale demand in total was 98.6% year-on-year.
- Specified Scale Demand (Deregulated segment)
Thanks to the continuing recovery trend in demand, electric power sold for commercial use was 100.9% year-on-year. Overall power demand in the specified-scale sectors totaled 100.4% 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
Despite a high operating rate by the post-quake reconstruction, a lower production in some industrial sectors and operation of private power generation, large-scale industrial demand in total was 100.1% year-on-year.
Electricity generated and purchased in June totaled 6,333 GWh, 99.9% as compared with the same period of the previous year.
(Power generated by our own hydro power stations)
Our hydro power generation output totaled 825 GWh, an increase of 156 GWh from the same period last year, due to the high flow rate, 115.1%, and a resumption of hydro power stations damaged by the torrential rain in Niigata and Fukushima
(Power generated by our own thermal power stations)
Due to a decrease in power receiving from other company's thermal power stations, power generated at our own thermal power plants totaled 4,353 GWh, an increase of 183GWh from the same period last 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, an increase of 6 GWh, year-on-year.
(Power purchased)
Since operation of thermal power station of other companies was different from that of the same period of the previous year, total power purchased from others totaled 1,748 GWh, a decrease of 390 GWh from the same period of the previous year.
