Annual power generation hours of Class II wind farm

Are wind turbines generating electricity daily or hourly?

Electricity generation from wind turbines in the United States set daily and hourly records in the final months of 2020. Hourly data collected in the U.S. Energy Information Administration’s (EIA) Hourly Electric Grid Monitor show an hourly record set late in the day on December 22 and a daily record set on the following day.

What is a resource wind speed class?

Starting with the 2020 ATB, the TRG-based classification was replaced with a simpler set of resource wind speed classes defined based only on annual mean wind speed. For land-based wind, each of the potential wind sites represented in the ReEDS model is associated with 1 of 10 wind speed classes.

What is wind speed Class 1?

Wind Speed Class 1 is suggestive of a resource-rich wind resource that is most attractive for wind project development, and Wind Speed Class 10 represents a less favorable wind resource site. Land-Based Wind Resource Classes

How does wind generation affect the value of a power plant?

For example, the match between hourly wind generation and hourly electricity demand can impact assessments of the value of wind plants 1, 2, 3, 4, 5, 6, the timing of wind output can influence operational decisions across power grids 7, 8, and can even impact long term planning 9, 10, 11, 12.

How many MWh does wind generate in a year?

In 2020, wind electricity generation reached a record-breaking 1.76 million MWh on average. This accounts for approximately 9% of the total electricity generation in the U.S. for the year.

Where can I find wind speeds and estimated generation?

PLUSWIND provides wind speeds and estimated generation on an hourly basis at almost all wind plants across the contiguous United States from 2018–2021. The repository contains wind speeds and generation based on three different meteorological models: ERA5, MERRA2, and HRRR. Data are publicly accessible in simple csv files.
