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.

During winter months, the use of bunker fuel oil to generate electricity at Tufts Cove can increase due to factors such as economics and/or pipeline pressure drops driven by increased gas demand. The availability (including scheduled maint...

AI summary During winter months, bunker fuel oil may be used at Tufts Cove for electricity generation due to factors like economics and pipeline pressure drops. NS Power considers the availability and cost of bunker fuel oil versus natural gas, along with pipeline maintenance schedules, in its optimization calculations for fuel dispatch.

3.4 Forecasting of Fuel Needs According to the Forecasting Methodology described in Appendix B of the FAM's POA ("Appendix B"), NS Power produces fuel forecasts required to set the Base Cost of Fuel a year or more in advance in an exercise...

AI summary NS Power uses PLEXOS® and PortOps® to forecast fuel needs, optimizing for least cost and transmission security. Forecasts are prepared annually and updated quarterly, with methodologies aligned to best practices. Both tools are industry-leading and not customized by NS Power.

AI summary The document outlines different forecasting approaches used by NS Power for long-term, Day Ahead, and Real Time dispatch planning. Each function uses different data sources and focuses, leading to varying results for the Tufts Cove facility. These variations are expected and not inherently problematic.

b. Recommendations R2: Provide necessary information in a timely manner and have the Marketing Desk dynamically update PortOps® to include up to date data for both energy and ancillary requirements and prices.71 As the complexity of the sy...

AI summary The recommendation emphasizes the need for timely information provision and dynamic updates to PortOps® to include current data on energy and ancillary requirements and prices, addressing system complexity and data synchronization issues with the Control Center.

b. Recommendations R7: Plan natural gas procurement based on the Day-Ahead market and allow the flexibility to accommodate a potential swing in usage to support real-time economic dispatch optimization (long or short). The allowable swing...

AI summary The recommendation suggests planning natural gas procurement based on the Day-Ahead market, allowing flexibility to adjust for potential usage swings. This flexibility should be informed by historical data and economic dispatch outputs, with future adjustments based on performance and cost considerations.

Theoretical Economic Benefits Implementation of the Automation and Optimization Tools will likely bring economic benefits in the form of risk avoidance of system reliability, and in the most economic dispatch that reflects real-time condit...

AI summary NS Power is evaluating the theoretical economic benefits of implementing automation and optimization tools, which could improve system reliability and dispatch efficiency. Concentric has been retained to estimate these benefits, though the analysis is based on assumptions and not a comprehensive optimization exercise.
