Lena Evaluates Wind Turbine Output Across 4 Sites: Key Insights on Daily Generation and Contribution
Wind energy plays a crucial role in the global shift toward renewable power, and efficient monitoring of turbine output is essential for optimizing performance across major installations. Recent analysis by Lena, a renewable energy analyst, evaluated daily electricity generation from four wind turbine sites to assess output consistency and identify key contributors.
The daily generation values (in kWh) are:
- Site 1: 12.4 kWh
- Site 2: 15.6 kWh
- Site 3: 9.8 kWh
- Site 4: 17.2 kWh
Understanding the Context
Step 1: Calculate Total Daily Output
To understand overall performance, we begin by summing the output from all four sites:
Total output = 12.4 + 15.6 + 9.8 + 17.2 = 54.0 kWh
Step 2: Determine the Median Daily Output
With four data points (an even number), the median is the average of the two middle values after sorting. Sorting the outputs:
9.8, 12.4, 15.6, 17.2
The 2nd and 3rd values are 12.4 and 15.6. Their average gives:
Median = (12.4 + 15.6) / 2 = 28.0 / 2 = 14.0 kWh
Step 3: Compute Site 2’s Contribution Percentage
Site 2 generated 15.6 kWh out of a total of 54.0 kWh. To find its share:
Contribution percentage = (Site 2 output / Total output) × 100
= (15.6 / 54.0) × 100 ≈ 28.89%

Key Insights
Conclusion
Lena’s evaluation reveals that while Site 2 leads in daily generation, the average output across all four sites stands at 14.0 kWh, providing a benchmark for performance. Site 2 contributes approximately 28.89% of the total daily wind energy output, highlighting its significant role in the network. Continuous monitoring like this supports better maintenance, forecasting, and optimization of wind farms.
Tracking daily generation across sites empowers operators to maximize energy yield and ensure reliable renewable power delivery.
