Now, a new actor enters: "GreenWind," a wind farm in the windy western plains. They build 500 MW of turbines. But when the wind blows, it congests the only transmission line eastward, collapsing the local price to -$20/MWh (they pay to export). GreenWind is going bankrupt not from lack of wind, but from congestion risk .

A perfect free market would explode the grid. A perfect planned economy would bankrupt it. Now, a new actor enters: "GreenWind," a wind
Years pass. Ethan builds a stable market. But then, a strange problem emerges. Wholesale prices average $50/MWh, but new gas turbines cost $80,000/MWh to build over their lifetime. No one builds new plants. Old plants retire. The reserve margin shrinks. GreenWind is going bankrupt not from lack of
