Abstract
The demand for electric power in Japan was 46, 300, 000, 000 kWh in 1950, about twice of that in 1930. Recently the rate of yearly increase of the demand is about 10 per cent. The capacities of power stations are 37, 000, 000, 000 kWh, therefore the shortage is very serious in winter. It is expected to supply the cheap, electric power more stably by the construction of reservoirs and dams or by the operation of coal power stations. The budget for the electricity development plan which started in 1949 is 10, 000 million yen a year but still insufficient to accomplish the plan. In Hokkaido we can not get cheap and enough power owing to its geographical and poor industrial situations. To solve this matter it is hoped to develop abundant natural reservoir and, in coal fields, to use low grade coals.
