The water inflow rate rose from 89.7% in the same period of the previous year to 107.3%, and hydroelectric generation reached 112.7% of the prior-year level. Accordingly, the impact of higher fuel costs due to lower water inflows has weakened. - FY2021-Q1MitigatedAnnual report
「Hydroelectric generation 3,347 3,839 114.7 Water inflow rate (%) 80.2 89.7」
The water inflow rate rose from 80.2% in the same period of the previous year to 89.7%, and hydroelectric generation also increased by 14.7% year on year. Accordingly, the impact of higher fuel costs due to lower water inflows has weakened. - FY2020-Q1MaterialisedAnnual report
「Operating expenses increased by ¥29,776 million, or 4.3%, year on year to ¥726,763 million, mainly because lower water inflows and other factors increased fuel costs, and because expenses increased in line with higher revenue in the gas and other energy businesses and the lifestyle and business solutions business.」
The water inflow rate in the first quarter of fiscal 2019 was 80.2%, down from 109.7% in the same period of the previous year. Lower water inflows and other factors materialized as drivers of higher fuel costs.
