「Nuclear power generation 12,926 25,882 200.2」
Nuclear power generation was 200.2% of the previous year's level, and the disclosure states that generation increased as the nuclear capacity factor rose. - FY2019-Q3RestatedAnnual report
「On the expense side, operating expenses were ¥2,255,801 million, up ¥190,359 million, or 9.2%, year on year. This reflected higher costs resulting from rising fuel prices and increased electricity sales volume and inter-area and sales to other companies, which outweighed the cost reductions resulting from the resumption of operations at nuclear plants and efforts to thoroughly improve management efficiency.」
The disclosure continues to cite cost reductions resulting from the resumption of operations at nuclear plants, but does not indicate further progress on nuclear restarts. - FY2019-Q2RestatedAnnual report
「On the expense side, operating expenses were ¥1,501,955 million, up ¥114,712 million, or 8.3%, year on year. This reflected higher costs resulting from rising fuel prices and increased electricity sales volume and inter-area and sales to other companies, which outweighed the cost reductions resulting from the resumption of operations at nuclear plants and efforts to thoroughly improve management efficiency.」
The disclosure continues to cite cost reductions resulting from the resumption of operations at nuclear plants, but does not indicate further progress on nuclear restarts. - FY2019-Q1RestatedAnnual report
「On the expenditure side, operating expenses were ¥696,986 million, an increase of ¥20,792 million, or 3.1%, from the same period of the previous year. This was despite thorough efforts to improve management efficiency and a reduction in costs resulting from the resumption of operations at nuclear plants, as costs increased due to higher fuel prices and higher inter-area and third-party electricity sales volumes.」
The disclosure continues to cite cost reductions resulting from the resumption of operations at nuclear plants, but does not indicate further progress on nuclear restarts. - FY2018AdvancedAnnual report
「The company will continue safe, stable operations at Takahama Power Station Units 3 and 4 and reduce electricity rates following the restart of Oi Power Station Units 3 and 4. It will also steadily carry out safety-related construction for operation of nuclear plants beyond 40 years, while advancing decommissioning work safely and efficiently.」
The company identifies the continuation of safe, stable operations at Takahama Power Station, the restart of Oi Power Station Units 3 and 4, safety-related construction for operations beyond 40 years, and decommissioning work as specific initiatives. - FY2018-Q3RestatedAnnual report
「On the expenditure side, operating expenses increased despite thorough efforts to improve management efficiency and the cost reductions resulting from the resumption of operations at Takahama Power Station Units 3 and 4, as thermal fuel costs increased due to higher fuel prices and other factors.」
The disclosure continues to cite cost reductions resulting from the resumption of operations at Takahama Power Station Units 3 and 4, but does not indicate further progress on nuclear restarts. - FY2018-Q2RestatedAnnual report
「On the expense side, operating expenses were ¥1,387,242 million, up ¥40,277 million, or 3.0%, year on year. This reflected higher fuel costs and raw material costs for the gas and other energy businesses resulting from rising fuel prices, which outweighed the cost reductions from the resumption of operations at Units 3 and 4 of the Takahama Nuclear Power Station and efforts to thoroughly improve management efficiency.」
The disclosure continues to cite cost reductions resulting from the resumption of operations at Takahama Power Station Units 3 and 4, but does not indicate further progress on nuclear restarts. - FY2018-Q1AdvancedAnnual report
「On the expense side, operating expenses were ¥676,193 million, up ¥23,545 million, or 3.6%, year on year. This reflected higher thermal fuel costs resulting from rising fuel prices, which outweighed the cost reductions from the resumption of operations at Units 3 and 4 of the Takahama Nuclear Power Station and efforts to thoroughly improve management efficiency.」
The disclosure states that operations at Takahama Power Station Units 3 and 4 resumed and that this generated fuel cost reductions. - FY2017First statedAnnual report
「③ Nuclear restarts and safe, stable operations with safety as the top priority ・The company will keep firmly in mind that primary responsibility for nuclear safety rests with the operator. By making unremitting efforts to improve the safety and reliability of nuclear plants and continuing safe, stable operations, the group will use its full strength to restore confidence in nuclear safety and promote understanding of the need for nuclear power as a baseload source and for the nuclear fuel cycle.」
Nuclear restarts and safe, stable operations are identified as priority initiatives to be advanced by improving the safety and reliability of nuclear plants.
