Perfect Competition: This is a situation that prevails in the market where there are numerous buyers and sellers. When a market is in perfect competition, the price of a product cannot be influenced by a single buyer or seller.

Supply Curve: This is the relationship between the quantities supplied by the producers in the market for a good or service at different prices, shown with the help of a graph.

Demand Curve: This is the relationship between the quantities demanded by the consumers of a good or service at different prices, shown with the help of a graph.

Break-even Price: This is the level of price when the economic profit is zero. The price is said to break-even when it is in equilibrium in the long-run. This happens when the price is equal to the lowest average total cost.

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. Table 3: Power Plant Capacity and Marginal Cost: Case 2 Plant # Energy Source Capacity (MW) MC (S/MWh) 2 Oil 100 90 3 Natural Gas 500 50 4 Nuclear 600 0 5 Solar 300 5 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).
