Internal inspection confirmed significant damage, including melting of part of the copper conductors, necessitating extensive repairs including replacement of internal transformer components. The cause is estimated to be insulation breakdown due to a lightning strike. Measures such as reinforcing lightning arresters will be implemented going forward.\n\n### Outlook and Performance Impact\nRestoration is expected around spring 2027. During the outage, supply capacity will be secured through operation of other thermal and hydroelectric power plants and market procurement. An impact of approximately 20 billion yen on fiscal 2026 performance is anticipated due to increased costs for substitute power procurement; however, this may fluctuate based on future information.","jir_financial_highlights":"Increased procurement costs for substitute power during the outage: Approximately 20 billion yen (Unknown)\nRated output of Nanao Ota Thermal Power Station Unit 2: 700,000 kW (Unknown)\nRestoration outlook timing: Around spring 2027 (Unknown)","jir_category":"","jir_hashtags":"#HokurikuElectricPower, #GeneralIR, #ThermalPowerStationFailure","jir_key_figures":"Date of shutdown: 2025-12-30\nExpected restoration timing: Around spring 2027\nPerformance impact amount: Approximately 20 billion yen (forecast for fiscal 2026)","jir_meta_title":"[Hokuriku Electric Power] Restoration Outlook and Performance Impact of Nanao Ota Thermal Power Station Unit 2 | April 2026","jir_meta_description":"Hokuriku Electric Power announces shutdown of the main transformer at Nanao Ota Thermal Power Station Unit 2 and restoration outlook.
