AI summary NSPI conducted an economic analysis of the Tufts Cove 6 project, considering scenarios with and without duct-firing. The analysis uses two cases based on the 2009 IRP Update assumptions and shows that the net present value remains positive with duct-firing.

NON-CONFIDENTIAL 1 filing is that the project economics are no longer driven primarily by the 2 combined cycle conversion. 3 4 This change is the result of the reduced load assumed in the Base Load World. 5 Under this assumption, Tufts Cov...

AI summary The project economics have shifted due to reduced load assumptions in the Base Load World, leading to lower forecast dispatch for Tufts Cove Units 4 and 5. This has resulted in a negative NPV for the combined cycle conversion without duct-firing. The analysis assumes traditional NSPI load growth levels and notes that the economic analysis lacks the same parameter sensitivities as the 2009 IRP, particularly regarding potential lower natural gas prices.

NON-CONFIDENTIAL 1 2 The implications of this are that the analysis, in particular the Base Case analysis, 3 is likely conservative (i.e. benefits are likely understated) for the following 4 reasons: 5 6  The Tufts Cove Units are marginal...

AI summary The text discusses the implications of the Base Case analysis, suggesting it may be conservative due to factors such as the marginal cost nature of Tufts Cove Units, potential benefits from wind development, and continued savings from duct-firing. It emphasizes the value of increased natural gas-fired generation flexibility and favorable emissions profile despite higher capital costs.
