The Capacities window displays real time hub-to-hub transmission capacity between the areas selected in Market Information window and the areas selected in the Capacities drop down menu.
Choose which areas you want to view by selecting the filter at the top right hand corner of the Transmission Capacities window. Once selected you can modify the selection directly from the area already chosen.
Under each area you see hub-to-hub capacity for both directions. The left column displays the direction from main area to selected area, while the column to the right displays the opposite direction. This is illustrated with an arrow.
You may hide the Capacities window by clicking on the arrow on the left side bar. You may also drag the bar left or right to make the window larger or smaller.
