Bid To SEL Table
About
The Bid to SEL Table replicates the Bid Table, but only shows units that have an ability to turn down from their Final Physical Notification to their Stable Export Limit. This means that any units that are online but must be turned down first are excluded and wind farms are also excluded.
All entries can be sorted by either clicking on a column title or filtered by using the Filter Values dropdown "Time Selector", "Fuel/Location", "Values", and "Play Pause".
Note that using the left and right buttons when target time has been chosen by period will move from one settlement period to the next. This will take the average values across the settlement period. Within the settlement period levels of generation will change minute-to-minute and so LIVE and Custom Time allow for the selection of either the current position or the position at a particular time.
On this chart it is possible to examine the information at the accepted/declared
bids/offers at a selected group of units. By default the first 20 units on the table will be selected.
Then information about these units can be seen for those selected by using 'Pricing Unit Details' >
'See Declared Bids...'. The selected units can be changed by clicking on the cell containing the unit
name without click on the link on the name itself.
Included Data
The data on this chart is as follows:
- Next Price - The price for the next MWh of potential bid volumes.
- Next Volume - The volume in MW at which the next price applies for any potential bid volumes. Note that this can include more than one pair as pairs with the same price have been combined to make the data more easily consumable.
- Declared Price - The price for the complete bid volume down to either 0MW or the Maximum Import Limit (MIL).
- Declared Volume - The volume in MW for the complete bid volume down to either 0MW or the Maximum Import Limit (MIL).
- FPN - The pre-gate generation volumes in MW (final physical notification)
- BOA - The accepted volume in MW for this unit.
- EMV - The volume in MW of generation adjusted for balancing
- MEL - The availability or Max Export Limit in MW
- FPN to SEL - The time required to drop from the current FPN position to the Stable Export Limit (SEL) in minutes.
- SEL - The Stable Export Limit in MW or minimum possible reduction in generation without switching off.
- MZT - The Minimum Zero Time (or time which the unit must stay at zero after it has been shutdown).
- NDZ - The Notice to Deviate from Zero (or time to start up from zero after being requested to).
