ERCOT: Rolling Blackout Threat Averted In Cold Snap

ERCOT says the threat of rolling blackouts were averted on Jan 6, 2014.

As chilly weather grips much of Texas, the state's electricial grid operator is asking consumers to reduce their energy use, though it says a brief threat of rolling blackouts has been averted. 

In an alert sent at 8 a.m., the Electric Reliability Council of Texas, which operates the grid covering 85 percent of the state, issued an emergency alert, meaning the grid's power reserves had dropped below a comfortable threshold. 

But the situation, ERCOT said, was improving.

Electric Grid Operator Warns Summer Blackout Threat Could Recur

In a report released Thursday, the state's electric grid operator indicated that next summer could see a repeat of the rolling blackout threats that plagued Texas past summer. The reason: rising demand for electricity and some power plants going offline.

"If we stay in the current cycle of hot and dry summers, we will be very tight on capacity next summer and have a repeat of this year's emergency procedures and conservation appeals," Trip Doggett, chief executive of the Electric Reliability Council of Texas (ERCOT), said in a statement.

If crazy weather — like the deep freeze in February that caused large numbers of power plants to break down — hits again this winter, outages could also result then, the report said. But Doggett put the risk of this happening in the wintertime as "very low."

As record temperatures continue to bake Texas and air conditioning units run at full throttle across the state, Austin Energy is trying to reduce the potential impact of rolling blackouts.

Rotating power outages are preventive measures taken by the Electric Reliability Council of Texas. Austin’s utility will now spread the effect across 71 areas in Austin. On the above map, these areas are colored green. You can see a more detailed version of that map here.

The reason for this development: a flood of complaints when 20 percent of Austin Energy customers suffered extended (and repeated) power outages during rolling blackouts in February.

Update: Austin Energy has released an updated version of this map. You can find it and an explanation here.

Earlier: Texas is currently in Energy Emergency Alert Level 2 as the electricity grid struggles to power air conditioning amid sweltering temperatures. Level 3 would require energy companies like Austin Energy to begin rolling blackouts like those we experienced if February.

After the energy crisis this winter, Austin Energy General Manager Larry Weis gave a presentation on the power emergency. The presentation included a map delineating areas of the city connected to so-called "load shed" circuits. These are the circuits that are the first to get turned off in the event of rolling blackouts.
