TUFTS COVE The Bates White Audit observed that the Tufts Cove Units continue to be committed and dispatched outside of PortOps® under certain conditions.24 As a result, Bates White recommended that NS Power should investigate options avail...

AI summary The Bates White Audit found that Tufts Cove Units are dispatched outside of PortOps® under certain conditions, leading to discrepancies between forecast budgets and actual supply. The audit recommends investigating PortOps® options to align dispatch with gas purchase decisions. The variance is attributed to market dynamics and the flexibility of Tufts Cove units, not software configuration issues.
