戦前日本において定額制電灯料金が主流を占めた理由は、生産原価中固定費が大部分を占める水力発電が主電源であったこと、電力メーターが高価であったこと、需要家の電力使用時間帯が類似しておりロードカーブの形状が相似していたことであった。しかし定額制には電力を濫費する傾向が出やすく、器具を随時増加させることが困難であり、電力の用途が徐々に多様化してくると不都合になってきた。こうして１９２０年代前半から従量制料金が導入され始め、その割合は全国で２９％、市部では４９％まで上昇した。

The reason why fixed electric light rate was majority in pre-war Japan is that hydroelectric power generation that fixed cost is accounted for production cost was major power source , that electric meter was expensive , and that electric use time of demander was similar to each other so form of load curve was similiar. However, flat rate system was likely to be tend to waste electric power. Increasing appliance constantly was difficult. The way to use electric power came to be diversified gradually. then,It was inconvenient. In this way,measured rate came to be introduced since early 1920s. The percentage rose up to 29% in national wide and 49% in city.
