Texas has set a new record for electricity generated from wind. On November 27th 2016, the ERCOT system saw more than 15,000 megawatts of electricity provided to the grid from wind turbines.
The amount represented about 45% of the spot demand for power in the grid in the afternoon.
“We saw high wind output throughout the day, ranging from just over 10,000 MW during the late night hours to this peak output during the noon hour,” said ERCOT Senior Director of System Operations Dan Woodfin. “Over the years, ERCOT has taken a number of steps, such as improving renewable generation forecasts, to allow us to operate the grid reliably on days like this.”
During the period, total output from wind approach the system capacity of 17,000 MW.
Coal’s Importance To Texas Electricity Continues To Decline
The use of coal to generate electricity in Texas continues to slide. Just ten years ago, half of the electricity in Texas came from the burning of coal. Today, coal only contributes 20%.
Why the huge drop off? The two main factors are natural gas and wind energy, with solar and hydro also playing a part.
Texas is by far the largest producer of natural gas in the U.S., more than doubling the production of the #2 state, Pennsylvania. Texas is now producing so much natural gas, that a pipeline is being built that will send a significant amount of natural gas to Mexico to be used by their electricity generators.
Texas also produces more electricity via wind energy than any other state. There have already been days when the state saw more electricity produced from wind than from coal.
It is expected that by 2020, more than half of all coal-burning power plants in Texas will be shuttered.
ERCOT Releases The 2014 Breakdown Of Electricity Generation In Texas
Just 10 years ago, the majority of electricity generated in Texas was derived from the burning of coal. Since then, the state has taken great strides to diversify away from the high carbon-emitting energy source.
The electricity production numbers are now available for 2014. Last year Texas generated 36% of its electricity from coal, 41% from natural gas, 12% from nuclear plants and 11% from wind.
Texas is the largest producer of wind energy in the U.S., accounting for 20% of all wind energy produced in the nation. As additional transmission lines get more of West Texas and the Panhandle connected to the ERCOT grid, that number should continue to grow.
