What This Document Is
This document is a homework assignment (Homework #2, ES 300) for College Physics I (PY 211) at North Carolina State University. It focuses on applying economic principles to a natural gas power plant’s production decisions within a competitive electricity market. The assignment builds upon a previous homework assignment concerning the initial investment analysis of the plant.
Why This Document Matters
This assignment is intended for students enrolled in PY 211 who are learning to model real-world economic scenarios. It’s used to practice applying concepts of supply, demand, marginal cost, revenue calculation, and net present value (NPV) to a practical engineering problem. It exists to reinforce understanding of how market prices influence production strategies and overall project profitability.
Common Limitations or Challenges
This assignment focuses on a simplified model of the electricity market. It does not cover complexities like transmission constraints, varying marginal costs due to fuel price fluctuations, or detailed financial modeling beyond the scope of the provided spreadsheet.
What This Document Provides
The full document includes:
* A scenario involving a natural gas power plant operating in a competitive electricity market.
* Supply and demand data for peak and off-peak electricity hours.
* Questions requiring calculation of market prices based on supply and demand.
* Problems determining optimal production decisions based on marginal cost.
* Revenue estimations for different hour types and total annual revenue.
* An analysis of how revised revenue estimates impact the plant’s NPV and economic viability.
* Answers to the questions are provided for self-checking.
This preview does *not* include the detailed calculations, spreadsheet modifications, or the complete solutions to the problems.
