On the morning of Feb. 12, wind power provided 52.1 percent of the electricity for the 14-state grid known as the Southwest Power Pool (SPP). This is a significant milestone for wind, which has never before provided a majority of power for any U.S. grid, according to SPP.
SPP is responsible for 60,000 miles of power lines running from North Dakota and Montana to Texas, New Mexico and Louisiana. Wind generates about 15 percent of the electricity in the SPP region and is third behind coal and natural gas.
The February 52.1 percent wind-penetration beat the April 2016 record of 49.2 percent. Wind-penetration is a measure of the grid’s electrical total load served by wind.
“Ten years ago, we thought hitting even a 25 percent wind-penetration level would be extremely challenging and any more than that would pose serious threats to reliability,” Vice President of Operations Bruce Rew said in an SPP statement. …
