of Units 2 and 3 of the Ishikariwan Shin Port Power Plant from the previously planned 569,400 kW to 580,000 kW as a result of reviewing equipment specifications. Additionally, due to earlier readiness for construction of Unit 2, the start of construction has been advanced from May 2027 to August 2026. The output of Unit 1 was also adjusted from 1,708,200 kW to 1,729,400 kW; however, there is no change to its scheduled operation start date.\n\n### Outlook and Impact\nThe increased output and advancement of the construction start are expected to improve plant operating efficiency and enable earlier commencement of power supply. This will strengthen Hokkaido Electric Power\u2019s power supply framework and contribute to future stable supply. The operation commencement dates remain unchanged, with Unit 2 scheduled for fiscal year 2030 and Unit 3 for fiscal year 2033.","jir_financial_highlights":"Ishikariwan Shin Port Power Plant Unit 1 Output: 1,729,400 kW (Increased from 1,708,200 kW previously)\nIshikariwan Shin Port Power Plant Unit 2 Output: 580,000 kW (Increased from 569,400 kW previously)\nIshikariwan Shin Port Power Plant Unit 3 Output: 580,000 kW (Increased from 569,400 kW previously)\nIshikariwan Shin Port Power Plant Unit 2 Construction Start Timing: August 2026 (Advanced from May 2027 previously)","jir_category":"","jir_hashtags":"#HokkaidoElectricPower, #BusinessStrategy, #PowerPlant","jir_key_figures":"Unit 1 Output: 1,729,400 kW (Increased from 1,708,200 kW previously)\nUnit 2 Output: 580,000 kW (Increased from 569,400 kW previously)\nUnit 2 Construction Start Timing: August 2026 (Advanced from May 2027 previously)","jir_meta_title":"Hokkaido Electric Power Announces Increased Output and Earlier Construction Start for Units 2 and 3 at Ishikariwan Shin Port Power Plant","jir_meta_description":"Hokkaido Electric Power has increased the output of Units 2 and 3 at the Ishikariwan Shin Port Power Plant from 569,400 kW to 580,000 kW and advanced the construction start of Unit 2 from May 2027 to August 2026.
