Load Transmission Data Panel
Access
The Data > Load Data menu option in the Powerflow Case Definition Window.
Purpose
To specify the date range of Transmission data you want to load into a Powerflow Case Definition from you default Transmission System data source.
The default EMarketOffer data source for Transmission System data
When uploading Transmission System data into a Powerflow Case EMarketOffer first checks the Inputs sub-folders for valid EM6/COMIT/Ellsoft files, and uses these in preference to data from an online database, even when a connection to obtain Transmission System data has been defined.
Transmission System Data Loading Modes
Transmission System data can be loaded into a Powerflow Case Definition in one of two modes:
- Date Range Mode
- Period Mode
Date Range Mode
Accessed by clicking on the "Date Range" tab under the "Transmission" heading.
Purpose
To select a date range for loading a Powerflow Case Definition with Transmission System data. This Mode is only available when Transmission System data can be obtained from EM6/COMIT/Ellsoft provided files.
A Definition loaded through the Date Range Mode will contain the following:
- Base Grid Configuration
- All Re-ratings applied during the date range
- All Group Constraints applied during the date range

Period Mode
Accessed by clicking on the "Period" tab under the "Transmission" heading.
Purpose
To select a specific period which will provide the basic Transmission System data for all periods in your Powerflow Case Effective Date Range. This is the only loading option available when EM6/COMIT data files are not available.
NOTE: When using Period Mode EMarketOffer applies the basic grid and re-ratings to obtain the System Configuration for the Period and applies this to all periods in the Powerflow Case Effective Date Range. It does not keep specific record of Circuit re-ratings or Group Constraints, which are kept when loading in Date Range Mode.
Control of the Transmission data takes place through the Load Transmission Data Panel in Period Mode.
