WRECK COVE The Bates White Audit recommended that NS Power should investigate options available in PortOps® to determine Day-Ahead and Real-Time schedules that consider economic optimization in the determination of target levels for Wreck...
AI summary The Bates White Audit suggests that NS Power should explore PortOps® to optimize Wreck Cove's scheduling, considering economic factors. Wreck Cove is currently dispatched based on physical limitations and hydrology, but its optimization potential is constrained. The report discusses modeling Wreck Cove within PortOps® to improve dispatch and address concerns raised by the auditor.
a. Observations O7: Wreck Cove is currently configured within PortOps® to optimize its economic value for Day Ahead and Intraday markets and includes optimization of both its energy and ancillary contribution to the portfolio (see O1). As...
AI summary Wreck Cove is optimized in PortOps® for Day Ahead and Intraday markets, with dispatch increasingly determined in Real Time by the Control Center. As renewable energy grows, the dispatch differences between Wreck Cove and Tufts Cove's gas units will increase, but this is expected as both become swing units for the system.
