This dataset is (surplus or shortage) imbalance price in the Japanese electricity market from March 2022. The data source is here.

• After the full liberalization of retail electricity in 2016, a new system of simultaneous balancing of planned values ​​was introduced, and retailers and power generators create demand and power generation plans for each 30-minute period, dividing a day into 48 periods, and operate to match supply and demand by one hour before actual supply and demand (gate close).
• If an imbalance occurs in actual supply and demand, the general power transmission and distribution company issues a command to the power source (adjustment power) to adjust to eliminate the imbalance.
• Power generators and retailers each formulate a power generation plan and a demand plan for the next 48 periods by 12:00 the day before. Power generation plans and demand plans can be changed up to one hour before each period.
• The difference between the plan and the actual result (imbalance) is compensated for and absorbed by the power transmission and distribution company using its adjustment power.
• The person who caused the imbalance must subsequently settle the unbalanced amount of electricity with the electricity transmission and distribution company as an imbalance price.
