Tougher building codes would make homes in places like Texas better insulated against the cold. Investments in electricity storage and distribution would help. Generators must insulate pipelines and other equipment. “People turn up their furnaces now because there isn't a financial incentive for them not to do it,' Borenstein said.Įxperts also say more fundamental - and costly - changes must be made. Like in other places, Texans might be more willing to adjust their thermostats a few more notches if regulators imposed a system that required households to pay higher prices during periods of peak demand and lower rates at other times.

Of course, those steps are sometimes easier said than done, especially during record-breaking temperatures.

Start with the obvious steps: When power companies or grid operators warn about trouble coming, turn down your thermostat and avoid using major appliances. WHAT CAN BE DONE TO REDUCE ROLLING BLACKOUTS? Once the outages started, some utilities were unable to provide information about how long they might last. The lighthearted attempts at humor were lost on residents, few if any of whom were told in advance when their homes would lose power. Last weekend they issued appeals for power conservation, and ERCOT tweeted that residents should “unplug the fancy new appliances you bought during the pandemic and only used once.' In Texas this week, grid operators and utilities knew about the dire weather forecast for at least a week.

In Texas, as in California last August, grid operators tell utilities to reduce load on the entire system, and it is up to the utilities to decide how to do that. Rolling blackouts are usually triggered when reserves fall below a certain level. Some areas never lost power, while others were blacked out for 12 hours or longer as temperatures dipped into the single digits. Often areas with hospitals, fire stations, water-treatment plants and other key facilities are spared.īy rolling the blackouts, no neighborhoods are supposed to go an unfairly long period of time without power, but that was not always the case this week in Texas. Usually, utilities black out certain blocks or zones before cutting off power to another area, then another. That raised questions whether some power generators who buy in the wholesale market may have had a profit motive to avoid buying more natural gas and simply shut down instead. The staggering imbalance between Texas' energy supply and demand also caused prices to skyrocket from roughly $20 per megawatt hour to $9,000 per megawatt hour in the state's freewheeling wholesale power market.

None of them were adequately weatherized or prepared for a full realm of weather and conditions.' “Every one of them is vulnerable to extreme weather and climate events in different ways. “Every one of our sources of power supply underperformed,' Daniel Cohan, an associate professor of civil and environmental engineering at Rice University in Houston, tweeted.

By Wednesday, 46,000 megawatts of power were offline statewide - 28,000 from natural gas, coal and nuclear plants and 18,000 from wind and solar, according to the Electric Reliability Council of Texas, which operates the state’s power grid. The gap between the winter and summer supply reflects power plants going offline for maintenance during months when demand typically is less intense and there's not as much energy coming from wind and solar sources.īut planning for this winter didn’t imagine temperatures cold enough to freeze natural gas supply lines and stop wind turbines from spinning. The state has a generating capacity of about 67,000 megawatts in the winter compared with a peak capacity of about 86,000 megawatts in the summer.

Demand spiked to levels normally seen only on the hottest summer days, when millions of air conditioners run at full tilt. Plunging temperatures caused Texans to turn up their heaters, including many inefficient electric ones. And power outages have become a rite of summer and autumn in California, partly to reduce the chances of deadly wildfires.īut the fact more than 3 million bone-chilled Texans have lost their electricity in a state that takes pride in its energy independence underscores the gravity of a problem that is occurring in the U.S. Utilities from Minnesota to Mississippi have imposed rolling blackouts to ease the strain on electrical grids buckling under high demand during the past few days. This isn't just happening in Texas, of course. DALLAS - The power outages tormenting Texas in uncharacteristically Arctic temperatures are exposing weaknesses in an electricity system designed when the weather's seasonal shifts were more consistent and predictable - conditions that most experts believe no longer exist.
