Bid Table
About
The Bid Table provides a list of all units in the market able to be bid down along with the price at which they will reduce output and any other relevant information. 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". Actions where plants have been turned down are either coloured in yellow or turquoise. Yellow indicates the action has been taken for locational reasons while turquoise indicates energy reasons behind the action.
This example shows that the South Humber Bank 1 and 2 are being turned down for location-specific reasons, while the turquoise coloured plants such as Drax 2, 3 and 4 are turned down for energy reasons.
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.
