Balance delta
The 'Balance delta’ table shows the quantities of regulating and reserve capacity TenneT has requested for its operations. It shows these quantities for each minute of the most recent half hour.
Explanation
The time indication comprises:
- Number (1-30): fixed number of the line in the overview (1 is the most recent).
- Sequence number: sequence number of the presented minute information in the 24 hours concerned, especially for the correct processing of summer time.
- Time: hour and minute when the values were determined.
- Regulating: the regulating capacity activated by the national Load Frequency Control (LFC) system:
- up: quantity of the activated upward adjustment capacity (sum of upward adjustment signals)
- down: quantity of the activated downward adjustment capacity (sum of downward adjustment signals) - Reserve: quantity of dispatched bids for reserve capacity:
- up: quantity of dispatched bids for reserve capacity on the upward adjustment side
- down: quantity of dispatched bids for reserve capacity on the downward adjustment side - Emergency capacity indicator (0, 1): this operational parameter is immediately set to 1 upon activation of emergency capacity. Depending on the dispatch time of the activated emergency capacity, a price for emergency capacity will be established in this PTU which will act as a determining factor for the imbalance price.
The emergency capacity indicator in the overview of settlement prices will play a leading role in the settlement.
How to use this page?
When you open this web page you will see the data for today’s most recent 30-minute period. TenneT updates this information once every minute. You can also view data relating to the past two hours; this information is not updated every minute. Apart from the line number, a line in the overview will remain empty if no up-to-date information is available due to disruptions. Empty lines will be completed at a later time, once the information within the time window of the overview becomes available.
A delay of a few minutes in the presentation of the real-time information is inevitable. This is the result of the processing steps required. Via the ‘export data’ function, historical Balance Delta information can be obtained. To do this you must enter the desired date. The overview is accompanied by a shortcut that can be used to download the presented Balance Delta information in XML format.
After the introduction of the page Balance delta with prices, this page will be unpublished after a couple of months, including related downloadoptions.
