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…
Respond to L.R.
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. Table 5: Hourly Demand (selected hours) Hour Demand (MWh) 4 AM 800 10 AM 1000 ... 2 PM 1100 ... 6 PM 1300 (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?

Case 1) NG price decreases Now, suppose that the price of natural gas decreased substantially, causing the marginal cost of the NG power plant to decrease to MC = $35/MWh. The demand is the same as in Case 0. (a) Draw a new supply curve that reflects the MC change of the NG power plant. (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) What happened to the coal power plant?

- Don't used Ai solutionarrow_forwardHow human recource allocated in an economic?arrow_forwardRespond to B.A. I have chosen Gross Domestic Product (GDP) as the macroeconomic indicator to review and provide a forecast prediction. Based on the current trend I predict a 2% annual GDP growth rate, indicating an unstable economy due to the impact of Donald Trump's tariffs on some countries and other other economic factors. This growth rate is lower than the historical average , indicating a slowdown in economic expansion. Overall, the forecast suggests a modest growth in GDP, but with potential risks and uncertainties ahead. But if he reverse his tariff policies, I think it could possibly result in a strong economic growth. As the removal of tariffs would likely minimize the costs for businesses and consumers and also rise trade and economic activities. Provide feedback/comments this post. You could agreement or disagreement (including why you agree or disagree). Or you could expand on this post by sharing different views and predictions.arrow_forward
