In Ishikari Bay near Sapporo, 10 projects are planned to generate 11 GW of offshore wind power, with 112 MW of wind power partially put into operation in January 2024. The applications of offshore wind power generation remain undecided, and supplying of electricity to Tokyo via submarine cables and other means is being planned. On the other hand, this study assumes local production for local consumption of electricity, and considers supplying electricity generated in Ishikari Bay to Sapporo, a major consumer of electricity and heat, by interconnecting it with the surrounding onshore variable renewable energy sources. However, the maximum output of the regulating power to stabilize supply-demand fluctuations and the capacity of the regulating power to stabilize the daily disparity are unknown. This study elucidates the maximum output and storage capacity when ammonia, methylcyclohexane, hydrogen, and sodium sulfur batteries are introduced as the regulating power.
