Hourly graph of wind farm power generation

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.

How much electricity is generated by wind?

In the United States, wind-powered electricity generation reached 1.76 million MWh on December 23, 2020, accounting for approximately 17% of the total electricity generation on that day. On average, wind accounted for 9% of U.S. electricity generation in 2020. Wind-powered electricity has increased in the United States as more wind turbines have been installed in recent years.

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.

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.

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.
