Daily power generation of wind power

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.

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.

What percentage of electricity is generated by wind?

In 2022, wind generation accounted for ~10% of total electricity generation in the United States. As wind energy accounts for a greater portion of total energy, understanding geographic and temporal variation in wind generation is key to many planning, operational, and research questions.

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 much electricity does a 90m wind turbine generate?

Global onshore and offshore wind generation potential at 90m turbine hub heights could provide 872,000 TWh of electricity annually. 9 Total global electricity use in 2022 was 26,573 TWh. 10 Continental U.S. wind potential of 43,000 TWh/yr 9 greatly exceeds 2022 U.S. electricity use of 4,000 TWh 6.

What are wind speeds and generation based on?

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. Modeled generation is compared to regional and plant records, which highlights model biases and errors and how they differ by model, across regions, and across time frames.
