3.1        Hourly OBA Calculation

•BTG

oBTG Hourly OBA (Sm3) = GPE Hourly Nomination - BTG Hourly Value

oBTG Hourly Estimated Value = Total GPE Hourly Nomination - Total BTG Hourly Value (until the moment of calculation)

•SSTTBV

oSSTTBV Hourly OBA = GPE Hourly Nomination - SSTTBV Hourly Value

oSSTTBV Hourly Estimated Value = Total GPE Hourly Nomination - Total SSTTBV Hourly Value (until the moment of calculation)

•SIMULATED HOURLY OBA

oEstimated BTG Total OBA = Last BTG OBA + Total BTG Hourly OBA

oEstimated SSTTBV Total OBA = Last SSTTBV OBA + Total SSTTBV Hourly OBA

3.2        Limit Exceeded

When the OBA limits are approached or the OBA limits are exceeded, the user is warned with animated alerts which are listed in Received Alarms.
