Tohoku Electric Power : Electricity Supply & Demand Report for April 2014

TOHOKU ELECTRIC POWER CO., INC.

May 28, 2014

Electric power sold in April totaled 6,327 GWh, which was 101.3% as compared with the same period of the previous year despite higher temperature resulting in low demand for heating. This was because of a post-quake reconstruction, a recovery in production in large industrial sector and a longer period of meter reading than the previous year. It exceeded the results of the previous year for 3 consecutive months.
Sales by customer segment were as follows.
- Non-Specified Scale Demand (Excluding deregulated segment)
Despite higher temperature resulting in low demand for heating, due to a post-quake reconstruction and a longer period of meter reading than the previous year, power demand in the lighting (residential) sector was 100.9% as compared with the same period of the previous year, and which exceeded the result of the previous year for the first time in 2 months.
Non-specified scale demand in total was 101.2% of the same period of the previous year.
- Specified Scale Demand (Deregulated segment)
Despite higher temperature resulting in low demand for heating, due to a recovery in demand, electric power sold for commercial use was 100.3% year-on-year.
Overall power demand in the specified-scale sectors totaled 101.3% 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 101.4% year-on-year, due to a recovery in production.
Large-scale industrial demand exceeded the performance of the previous year for 7 consecutive months.

Due to higher temperature in the middle and end of the month resulting in low demand for heating, electricity generated and purchased in April totaled 6,468 GWh, 97.6% as compared with the same period of the previous year. It fell below the performance of the previous year for the first time in 4 months.
(Power generated by our own hydro power stations)
Because of a high flow rate which was 106.6% during this period and resumption of operating in hydro power stations damaged by the heavy rainfall in Niigata and Fukushima, hydro power generation increased 138 GWh, year-on-year, to 904 GWh.
(Power generated by our own thermal power stations)
Since operation of power stations was different from that of the same period of the previous year, generated output totaled 4,522 GWh, an increase of 109 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 the amount of vapor in geothermal power stations decreased, generated output totaled 72 GWh, a decrease of 5GWh, 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 1,606 GWh, a decrease of 396 GWh from the same period of the previous year.
