The ERCOT headquarters in Taylor, TX. StateImpact Texas was given a tour of the facilities on June 6, 2012.
The ERCOT Grid Control Center at their headquarters in Taylor, TX. Controllers route electricity through over 40,000 circuit miles of high-voltage transmission wires.
Inside the ERCOT Grid Control Center at their headquarters in Taylor, TX. Human controllers can override computers if power is at risk.
When generators fail, controllers lean on large electricity users, like factories, that are paid to be ready to shut everything off at a moment’s notice.
Controllers monitor supply and demand to keep them perfectly balanced.
Controllers tweak the balance of supply and demand by activating backup generators.
Controllers make daily forecasts of the next day’s electric demand and supply down to every five minutes.
Controllers balance the need for power with the power given by their 550 generators in order to not waste resources.
Controllers look at wind and solar energy, which can vary the access of gatherable resources.
Controllers are in charge of monitoring every slight variation in power gathered, routed, and delivered to its 23 million consumers.
Controllers look at a distribution system so electricity can flow not just to consumers, but wherever it is needed most.
Imagine this: you’ve just gotten home from work. You worked right through lunch, as you often do, and now you just want to throw your pasta on the stove and relax in your air-conditioned home while you catch up with the news and… CLICK. Now your power’s out.
That frustration you just felt is exactly what the Electric Reliability Council of Texas (ERCOT), which manages the Texas Grid, is trying to prevent. However, it’s more complicated than just generating enough power for everyone.
StateImpact Texas got to see the ERCOT grid control center in person this week in order to get a better understanding of how blackouts are managed and limited. (You can see a slideshow of photos taken inside ERCOT above.) At the end of the day, it all comes down to a balance between load (demand for electricity) and generation of power. Continue Reading →

It’s not quite an eclipse, it’s more like the sun is going to have a beauty mark for a rare, fleeting moment. On Tuesday, Venus (the brightest planet in our solar system) will pass in front of the sun, and if you’re hoping to catch it, plan with care. If you miss it, you won’t have another chance of seeing it until the next century. December 11, 2117, to be exact.
“During the transit, Venus will appear in silhouette as a small, dark dot moving in front of the solar disk,” writes EarthSky, which reports on astronomy and science. “Here in Austin, Texas, we’ll see the first half of the transit, while the second half will take place after the sun goes beneath our horizon. In North America, it’ll be to our advantage to find a level western horizon, as the sun will be low in the west at the time of the transit.”
For information on the best possible time to witness the phenomenon in Texas, check out local times from the Transit of Venus website. For much of the state, the transit will be viewable starting at 4 p.m. Tuesday and and ending around 10 p.m. You’ll want a telescope with a solar filter to safely observe the passing.

Oil prices are finally going down (for the moment, anyways) but this year has been pretty painful at the pump. While price is most on our minds, there’s also plenty to think about with the production and impact of oil.
A new art app for the iPad aims to get viewers to think deeper on the subject.
The new app is simply called “Edward Burtynsky: Oil,” and features over a hundred images by the renowned photographer of industry. (Nearly a quarter of the images have counterpart audio-commentary by the artist). The app coincides with exhibitions of the same work at The Photographers’ Gallery in London (there’s video of that on the app, too) and at the Nevada Museum of Art in Reno starting June 9. The goal? To get people to think more about the oil industry’s impact. Continue Reading →

‘It’s a false sense of security if people think it doesn’t matter that one species is disappearing. To me, that tells me the whole system is in trouble” – Sarah Scott Mitchell, granddaughter of George Mitchell
The Cook’s Branch Conservancy is located on 5,600 acres in Montgomery County. The land was purchased by Texas oil & gas billionaire George Mitchell in 1964.
“We’re now getting close to the condition the settlers found it in. We’re restoring grasses and doing controlled burns.” -Sheridan Mitchell Lorenz, daughter of George Mitchell

What’s a carbon sink? It’s a process where the earth soaks up atmospheric carbon, which there is more and more of in the world. Those “sinks” take the form of forests and oceans, and a new study we reported on last week says that, contrary to previous research, the earth’s ability to soak up carbon has “increased roughly in line with rising emissions.” So herewith is a slideshow of some of those carbon sinks that are helping to eat up some of the carbon in the atmosphere.
The Australian drought forced the country to make some tough decisions. Will Texas follow suit?

A Country Fire Authority (CFA) staff monitor a giant fire raging in the Bunyip State Park near Labertouche, some 125 kilometres west of Melbourne, on February 7, 2009. More than 40 blazes raged across two states as a once-in-a-century heatwave pushed the mercury as high as 46 degrees Celsius (115 Fahrenheit) with fire bans in place across much of the south-east, with conditions said to be the worst since the Ash Wednesday wildfires of 1983, which killed 75 people and razed 2,500 homes.
A dead kangaroo lies beside a burnt-out section of the Hume Highway near Seymour, some 100 kilometres north of Melbourne on February 9, 2009 as raging Australian wildfires left at least 131 people dead amid a landscape of charred homes, bodies and devastated communities. The wildfires have become the deadliest in Australia’s history, destroying entire towns and wiping out families and amid the heartache there was also anger as police revealed they suspected some of the fires were started by arsonists, whom Prime Minister Kevin Rudd accused of “mass murder.”

One question that comes up when looking at the Texas drought is, are there any examples of other droughts the state could look to? Texas isn’t alone dealing with the issues of water and drought, and one of the most recent examples of a large population dealing with drought comes from Australia. (You can see a slideshow of the Australian drought above.)
“Australia is the biggest drama that has recently played out in the world of water,” said Ralph Eberts, the Executive Vice President of Black & Veatch Water, at the Texas Water Summit at the University of Texas Monday. Australia is just now emerging from a severe decade-long drought. At the peak South East Queensland hung on with less than fifteen percent of its water supplies remaining. Aussie wildlife and agriculture took a considerable blow. And failed rice and grain crops threatened to unhinge the global food supply.
A parallel can be drawn between Australia’s drought experience and that of Texas. Australia, like Texas, was caught in a bind with no warning. The drought experience across Australia varied considerably, with different regions undergoing various levels of stress. Texas has witnessed this variability with West Texas drawing the shorter straw.
But the duration of the Australian drought led to markedly different results. Continue Reading →
Tomatoes on the vine at Village Farms new thirty-acre greenhouse in Monahans, Texas.
The vines are suspended from the ceiling, with large cylinders circulating air beneath them.
The tomatoes are grown in coco peat instead of soil, greatly reducing impact on land and waterways.
Commissioner of Agriculture Todd Staples inspects the tomatoes.
Computers control temperature, air and humidity. Bees are allowed in for pollination, but other bugs are kept out, eliminating the need for pesticides. Large tubes keep air circulating beneath the tomatoes.
Doug Kling says “there’s a peacefulness” to the greenhouse.
The end product: bushels of Texas tomatoes.
Precisely-beveled glass diffuses light on the tomatoes, providing equal amounts of sunlight to the crop.
Commissioner of Agriculture Todd Staples and Village Farms officials tour the greenhouse.
Next time you buy a Texas tomato, check where it was grown. The answer might surprise you. That’s because ninety percent of the state’s tomatoes come from a few greenhouses in the arid deserts of Far West Texas. (You can see a detailed breakdown of how the process works in the slideshow above.)
The latest addition to that group is a massive glass facility in Monahans, outside of Odessa. It officially opened for business this week.
“Well, when you look at this, this is like a giant, 15-acre, indoor garden,” says Doug Kling, Senior Vice President for Village Farms, which owns and operates the greenhouse. “Pollinated [by] bees, and grown naturally. Where the sunlight comes in and you can smell the calyx. It’s kind of exciting. There’s a peacefulness to it.”Â

You’re going to need something better than wayfarers this weekend. The first annular solar eclipse of the 21st century for the continental U.S. is coming to Texas Sunday. You can see photos of some notable eclipses in the slideshow above.
The eclipse will start in Eastern Asia and cross east over the Pacific, ending in Central Texas. Here’s an interactive map of where the eclipse will pass, with peak viewing times. NASA says the eclipse will begin at 7:35 pm in Texas and peak at sundown. The best views will be from West Texas, particularly Amarillo, Lubbock and Midland-Odessa, where the eclipse will peak right around 8:30 pm. For those of you in the big cities of Austin, Dallas-Fort Worth, Houston and San Antonio, you won’t get to see the full peak phase of the eclipse because the sun will have set by then. But you’ll still be able to see some of it.
An annular eclipse is close to a total eclipse, but not quite. With an annular solar eclipse, the moon directly passes between the earth and the sun, casting a shadow on the earth’s surface. For a viewer on earth, the light from the sun is almost fully blocked creating a “ring of fire” around the moon.
NASA cautions viewers to not look directly at the sun and to not rely on standard sunglasses. Looking directly at the eclipse can cause permanent eye damage. “The ring of sunlight during annularity is blindingly bright,” Fred Ezpenack, an eclipse expert at NASA, warns on their website. Continue Reading →

A young boy cools off in the Volcano Lake slide, July 20, 2000, at the Wet ”N” Wild Waterworld in Anthony, Texas. A heat wave that stretches from Arizona to the southeast coast, is being blamed for at least 12 deaths in Texas and another six in Alabama and Louisiana. Health officials in some states say they won”t know how many people have died from sweltering temperatures until autopsies are complete. High humidity is making heat in the Southeast even deadlier than the dry heat of the Southwest.
It’s raining (and in some cases, flooding) across Texas. A popular question this morning will be: Is the Drought Over? And the answer to that largely depends on where you are. If you’re in East Texas, the answer is a qualified yes. (Many reservoirs still haven’t recovered.) In West Texas? There’s still a ways to go.
But regardless of whether or not the drought is technically abating, the issues behind it are here to stay. Texas is growing rapidly, and will not have enough water to meet its needs unless changes are made. (For an invigorating discussion of those issues, check out this Twitter chat from earlier in the week.)
For now, it’s nice to take a breath and appreciate the wet winter behind us and the hopefully-wet Spring/Summer ahead. Above is a slideshow of scenes of water in Texas to feast your eyes on in the meantime.
