"Wind power in Texas, a portion of total energy in Texas, consists of over 150 wind farms, which together have a total nameplate capacity of over 30,000 MW. If Texas were a country, it would rank fifth in the world: The installed wind capacity in Texas exceeds installed wind capacity in all countries but China, the United States, Germany and India."

You do the math and then consider what it would take to monitor and tie these together.
There is NO practical off the shelf method for battery storage of wind generated electricity on the level Texas wind generation produces. If there were, the wind generation and oil companies would be all over it.
"Starting in 2008, the wind power development boom in Texas outstripped the capacity of the transmission systems in place,[19] and predicted shortages in transmission capability could have dampened the growth of the industry. Until 2008, the growth in wind power "piggybacked" on existing lines, but had almost depleted spare capacity.[20] As a result, in winter the west Texas grid often had such a local surplus of power, that the price would fall below zero.[21][22] According to Michael Goggin, electric industry analyst at AWEA, "Prices fell below US −$30/MWh (megawatt-hour) on 63% of days during the first half of 2008, compared to 10% for the same period in 2007 and 5% in 2006."[23]"
Do you think the energy producers are philanthropists who like generating free power????
"In July 2008, utility officials gave preliminary approval to a $4.9 billion plan to build new transmission lines to carry wind-generated electricity from West Texas to urban areas such as Dallas. The new plan would be the biggest investment in renewable energy in U.S. history, and would add transmission lines capable of moving about 18,000 megawatts.[24] ERCOT curtailed wind power by 17% (3.8 TWh) in 2009, but that decreased to only 0.5% by 2014, as transmission improved, particularly the Competitive Renewable Energy Zone (CREZ) in 2013.[25][26][27] However the CREZ lines are sometimes maxed out, and in November 2015, prices were negative for 50 hours. "
Did you get that? ERCOT cut Wind production by 17% because WIND WAS PRODUCING TOO MUCH ELECTRICITY. Just think: if they had practical battery storage and connection to the national power grid, they'd be getting paid for their surplus and provide for Texas when the weather almost breaks ERCOT down like this summer and winter two years ago.
"Future developments
Like several Texas solar plants, some Texas wind power plants include storage, with more projects under construction.[42] One of the first such energy storage systems started as 36 MW in Notrees in December 2012. The system allows excess wind energy to be stored, making the output more predictable and less variable.[43][44]
If developed, the Tres Amigas HVDC link to the Western grid and the Eastern grid could allow more flexibility in importing and exporting power to and from Texas.[45]
A 300 MW offshore wind farm is planned for Galveston, and 2,100 MW for the Gulf Coast of Texas.[46] Making turbines that are able to yaw quickly could make them more likely to be able to survive a hurricane.[47] "
See? Just like I said. The best storage they can get now is for 36 MW. They are trying to develop storage but it just is not available yet.
Get over it.
