A wind farm consists of 15 turbines. On a high-wind day, each turbine generates 2.4 megawatts. On a low-wind day, output drops by 40%. If 6 days are high-wind and 4 are low-wind, what is the total energy output in megawatts over the 10 days? - Treasure Valley Movers

Why Wind Power Output Varies—and How It Adds Up

With growing interest in clean energy and sustainable power, wind farms are becoming a familiar sight across the United States. Each facility relies on clusters of turbines—often 15 or more—to generate electricity, particularly during high-wind periods. On a peak wind day, each turbine delivers 2.4 megawatts of power, producing steady, reliable energy. But when winds slow, output dips significantly—by nearly half—impacting overall daily or weekly generation. Understanding how these fluctuations shape annual energy production helps inform conversations around grid stability, renewable investment, and energy independence. Recently, data from operating wind farms has shown clear daily cycles influenced by weather patterns—underscoring real-time energy variability that matters to planners, investors, and environmentally conscious residents.

How Variability Shapes Total Energy Output
Across a 10-day period, wind generation fluctuates based on daily wind conditions. With 6 days categorized as high-wind and 4 as low-wind, total energy output reflects this balance. Each high-wind day contributes 15 turbines × 2.4 megawatts = 36 megawatts. Over 6 high-wind days: 6 × 36 = 216 megawatts. On low-wind days, output falls by 40%, reducing each day’s contribution to 60% of peak: 2.4 megawatts × 0.6 = 1.44 megawatts per turbine. Each low-wind turbine delivers 15 × 1.44 = 21.6 megawatts, so 4 low-wind days total 4 × 21.6 = 86.4 megawatts. Adding these gives a realistic estimate of 216 + 86.4 = 302.4 megawatts over the
