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.

This dataset includes the following columns:
