- FY2023WorsenedAnnual report
「The company is working to maintain the reliability of power generation and distribution facilities through thorough inspections and maintenance, and to secure a stable fuel supply and maintain and manage the supply chain for equipment and materials. However, if facilities are damaged by natural disasters, equipment failures or other events, or if disruptions to fuel supplies or the equipment and materials supply chain make it difficult to operate or maintain facilities, costs could increase due to recovery work and increased generation at other power plants following a plant outage, potentially affecting operating performance.」
In addition to conventional facility failure risks, the company explicitly identified the possibility that disruptions to fuel supplies or the equipment and materials supply chain could make operation and maintenance difficult, thereby expanding the scope of the risks. - FY2022RestatedAnnual report

「The 2018 Hokkaido Eastern Iburi Earthquake caused a blackout across Hokkaido, excluding the outlying islands, significantly affecting residents' lives and economic activity.」
The earthquake actually caused a blackout and supply disruptions across Hokkaido, bringing the risks of facility failures and supply disruptions to the fore. - FY2018RestatedAnnual report
「The company is working to maintain the reliability of power generation and distribution facilities through thorough inspections and maintenance. However, if facilities are damaged by natural disasters, equipment failures or other events, recovery costs could increase.」
The company continues to identify the risks of facility failures caused by natural disasters or equipment failures and the resulting recovery costs. - FY2017RestatedAnnual report
「The company is advancing research and development to address the rapid aging of power generation and distribution facilities and the high utilization of thermal power plants.」
The company is reaffirming its response to facility failure risks on the assumption that power generation and distribution facilities are aging and thermal power plants are operating at high utilization rates. - FY2016First statedAnnual report
「The risk of unplanned outages and supply disruptions at thermal power plants is increasing because the facilities are aging and the plants continue to operate at high utilization rates while periodic inspections and major repairs are being deferred. The company will work to strengthen facility maintenance and patrols to secure supply capacity.」
The company states that dependence on thermal power facilities continues while the Tomari Nuclear Power Station is suspended, and that risks are increasing against a backdrop of aging facilities, high utilization and deferred repairs.
