TOHOKU ELECTRIC POWER COMPANY, INCORPORATED TOHOKU ELECTRIC POWER CO., INC.

Electricity Supply & Demand Report for the 1st Half of FY2014 1. Electricity demand (See Table 1)
Electric power sold in the 1st half of FY2014 totaled 36,307 GWh, which was 98.9% year-on-year. While there were continuous post-quake reconstructions, decrease in air conditioning demand due to a warm spring and a cool summer and other factors lowered our electricity sales.
Sales by customer segment were as follows:
- Non-Specified Scale Demand (Excluding deregulated segment)
While there were continuous post-quake reconstructions, decrease in air conditioning demand due to a warm spring and a cool summer and other factors lowered power demand in the lighting (residential) sector, which was 96.7% year-on-year.
Non-specified scale demand in total was 96.9% of the previous fiscal year.
- Specified Scale Demand (Deregulated segment)
Although there were continuous post-quake reconstructions, decrease in air conditioning demand due to a warm spring and a cool summer and other factors lowered electric power sold for commercial use, which was 99.2% year-on-year. Overall power demand in the specified-scale sectors totaled 100.0% of the previous fiscal year.
In the industrial and other sectors, power demand mostly came from large-scale industrial customers, as described in the reference below.

- Large-scale industrial demand
While a post-quake reconstruction and a recovery of production continue, a low operating rate in some companies as well as an increase in the outputs of private generators lowered our large-scale industrial demand in total, which was 100.2% year-on-year.
Electricity generated and purchased in the 1st half of FY2014 totaled 39,201 GWh, 98.5% year-on-year, which fell below the performance of the previous year.
(Power generated by our own hydro power stations)
Even though a flow rate was down 2.8% year-on-year to 104.5%, a resumption of hydro power stations damaged by the torrential rain in Niigata and Fukushima increased our hydro power generation output, which totaled 4,625 GWh, an increase of 490 GWh year-on-year.
(Power generated by our own thermal power stations)
Because of an increase in hydro power generation output and a decrease in demand lowered our own thermal power generated output to 26,609 GWh, a decrease of 293 GWh year-on-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 inspections. Therefore, there was no output from nuclear power stations.
(Power generated by our own renewable power stations)
Differences of geothermal power stations' operations and other factors increased our renewable generated output to 439 GWh, an increase of 3 GWh year-on-year.
(Power purchased)
Differences of thermal power stations' operation of other companies and other factors decreased our power purchased from others to 11,262 GWh, a decrease of 1,211 GWh year-on-year.
