This is one of the obvious ways we could attempt to do that.

The state’s High Plains region, which covers 41 counties in the Texas Panhandle and West Texas, is home to more than 11,000 wind turbines — the most in any area of the state.
The region could generate enough wind energy to power at least 9 million homes. Experts say the additional energy could help provide much-needed stability to the electric grid during high energy-demand summers like this one, and even lower the power bills of Texans in other parts of the state.
But a significant portion of the electricity produced in the High Plains stays there for a simple reason: It can’t be moved elsewhere. Despite the growing development of wind energy production in Texas, the state’s transmission network would need significant infrastructure upgrades to ship out the energy produced in the region.
“We’re at a moment when wind is at its peak production profile, but we see a lot of wind energy being curtailed or congested and not able to flow through to some of the higher-population areas,” said John Hensley, vice president for research and analytics at the American Clean Power Association. “Which is a loss for ratepayers and a loss for those energy consumers that now have to either face conserving energy or paying more for the energy they do use because they don’t have access to that lower-cost wind resource.”
And when the rest of the state is asked to conserve energy to help stabilize the grid, the High Plains has to turn off turbines to limit wind production it doesn’t need.
“Because there’s not enough transmission to move it where it’s needed, ERCOT has to throttle back the [wind] generators,” energy lawyer Michael Jewell said. “They actually tell the wind generators to stop generating electricity. It gets to the point where [wind farm operators] literally have to disengage the generators entirely and stop them from doing anything.”

Wind energy is one of the lowest-priced energy sources because it is sold at fixed prices, turbines do not need fuel to run and the federal government provides subsidies. Texans who get their energy from wind farms in the High Plains region usually pay less for electricity than people in other areas of the state. But with the price of natural gas increasing from inflation, Jewell said areas where wind energy is not accessible have to depend on electricity that costs more.
“Other generation resources are more expensive than what [customers] would have gotten from the wind generators if they could move it,” Jewell said. “That is the definition of transmission congestion. Because you can’t move the cheaper electricity through the grid.”
A 2021 ERCOT report shows there have been increases in stability constraints for wind energy in recent years in both West and South Texas that have limited the long-distance transfer of power.
“The transmission constraints are such that energy can’t make it to the load centers. [High Plains wind power] might be able to make it to Lubbock, but it may not be able to make it to Dallas, Fort Worth, Houston or Austin,” Jewell said. “This is not an insignificant problem — it is costing Texans a lot of money.”
Some wind farms in the High Plains foresaw there would be a need for transmission. The Trent Wind Farm was one of the first in the region. Beginning operations in 2001, the wind farm is between Abilene and Sweetwater in West Texas and has about 100 wind turbines, which can supply power to 35,000 homes. Energy company American Electric Power built the site near a power transmission network and built a short transmission line, so the power generated there does go into the ERCOT system.
But Jewell said high energy demand and costs this summer show there’s a need to build additional transmission lines to move more wind energy produced in the High Plains to other areas of the state.
Jewell said the Public Utility Commission, which oversees the grid, is conducting tests to determine the economic benefits of adding transmission lines from the High Plains to the more than 52,000 miles of lines that already connect to the grid across the state. As of now, however, there is no official proposal to build new lines.
Sure would be nice to have such a proposal, wouldn’t it? That’s a thing that the Governor and the Legislature could make happen if they wanted to. Unfortunately, a lot of them don’t want to, and of course Greg Abbott is incapable of taking any positive action. So here we are, with those of us too far away from the existing turbines to benefit from them looking longingly at the Gulf of Mexico for some future relief. I don’t know how much it might cost to build out the transmission network (the story doesn’t say), or to invest in battery storage for solar energy (another thing we’re good at generating in this state, as noted in the story), but I’m sure we could find the money if we wanted to. First, though, we have to want to. And that means electing people who want to. Because we don’t have that now.
