2.1 INDICATOR BAL.1: BALANCING MEANS USED BY TSO AS % OF TOTAL TSO BALANCING VOLUME

2.1.1 Description

The BAL.1 indicator presents the percentage of use of all the balancing means a TSO can use: Short Term Standardised Products – STSP (i. e. title product, locational product, temporal prod- uct and temporal locational product) on trading platform(s), balancing platform or balancing services.

Article 9 of the BAL NC prioritises:

\\ The use of title products where and to the extent appropriate over any other available STSPs; and \\ The use of Within-Day (WD) products over Day-Ahead (DA) products where and to the extent appropriate.

This indicator gives an accurate assessment of a well-functioning short-term balancing market.
