Cost-benefit analysis of a natural gas lateral pipeline to the Annapolis Valley
Bibliographic record
Abstract
This a study of the economic benefit of bringing natural gas to the Annapolis Valley, Nova Scotia. Large volume potential customers are profiled and found to be primarily using Bunker C residual fuel oil, which then is contrasted with natural gas in terms of use, efficiency, price and environmental effects. Based on the customers‟ energy needs, the construction cost of a 105km 6 inch lateral pipeline connecting to the provincial pipeline network north of Halifax is calculated. With 2010 average prices for Bunker C and natural gas a Net Present Value of $51.8 million is established for the project with a 31% Internal Rate of return and break even of four years. As the economic value of this project depends greatly on the price differential between the fuels a sensitivity analysis is conducted. The environmental costs of emissions are quantified to incorporate externalities into the analysis. Limitations of the study examine why a favourable economic analysis does not necessarily mean a viable project. Based on the IRR the project does appear financially viable from a commercial standpoint.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
