4 FAQs about What are the wind power generation indicators

What are key performance indicators (KPIs) for the wind industry?

Key performance indicators (KPIs) are a solid and frequently used tool for this purpose. However, the KPIs used in the wind industry are not uni ed to date, which makes comparison in the industry di cult. Further, comprehensive standards on a set of KPIs for the wind industry are missing.

What metric is used to describe wind turbine specifications?

When comparing the economics of a wind farm to other sources of power generation - such as gas-turbines, coal power plants, or solar energy - a commonly utilized metric is the levelized cost of energy, or LCOE.

How is electricity generation from wind measured?

Annual electricity generation from wind is measured in terawatt-hours (TWh) per year. This includes both onshore and offshore wind sources. Data source: Ember (2026); Energy Institute - Statistical Review of World Energy (2025) – Learn more about this data Measured in terawatt-hours.

Is monetary-based availability a key KPI for wind energy performance?

First mentioned in this context by Hirsch et al. in 2016, monetary-based availability is not yet used in the wind industry but has potential to be the upcoming most important KPI to assess the overall performance of WTs. While the time-based availability solely considers downtime, the production-based availability focuses on lost energy yield.
