3. Case 2) Coal plants exit, and Solar generation enters the market
Now, let's consider a scenario where the coal power plant (#1) shuts down and exits the market,
and a solar generation facility is constructed. The capacity of the solar generation facility is the
same as the coal power plant that went out of business. The generation capacities of this market
are shown below, along with their MC.

Note that the solar plant (#5) can generate electricity only from 7 AM until 5PM. During these
hours, the plant can generate up to its full capacity (300 MW) but cannot generate any when
unavailable.
(a) Draw a supply curve for each hourly market (4AM, 10 AM, 2PM, 6PM).
(b) Find the market clearing prices and calculate how much electricity each power plant
generates in the hourly market (4AM, 10AM, 2PM, and 6PM).
(c) Find the…

To analyze consumer spending, you must review the macroeconomic indicators of Personal Consumption Expenditures (PCE) and Retail Sales over the past year.
Selected Macroeconomic indicators
Personal Consumption Expenditures (PCE) measure the value of household goods and services consumed and are a key indicator of consumer spending.
- Retail Sales: This tracks the total receipts of retail stores and provides insight into consumer demand and spending trends.
- Patterns over the past year:
Personal Consumption Expenditures (PCE) Over the past year, PCE has steadily increased, reflecting consumer confidence and willingness to spend. The growth rate has been moderate, driven by wage growth, low unemployment rates, and government stimulus measures. However, inflationary pressures have also impacted real purchasing power, leading to a mixed outlook.
- Retail sales have also experienced fluctuations but have generally trended upwards. After a…
4. Case 3) Electricity demand increases due to increased EV adoption
We will continue using the Case 2 supply curve (with the solar plant in operation) for this
analysis. Suppose that electricity consumption from electric vehicles (EV) increases
significantly. Consequently, electricity demand in the wholesale market increases at every hour.
The new demand levels are shown in Table 5 below.
The market operator has backup power plants (using natural gas) ready, with a total capacity of
300 MW and a MC of $100/MWh.

(a) Find the market clearing prices and calculate how much electricity each power plant
generates in the hourly market (4AM, 10AM, 2PM, and 6PM). Is there a specific hourly
market in which the market operator will need to dispatch backup generation?
(b) Compare the Case 2 scenario with the Case 3 scenario in terms of CO2 emissions and
average electricity price. Based on…
