On June 14th, 2021, the Electric Reliability Council of Texas (ERCOT) issued a Conservation Alert asking Texans to reduce their energy consumption. This alert will be in place until the end of the day Friday, June 18th. Here's what it means for Texans.

What You Should Do

ERCOT has asked Texans to do the following:

  • Set your thermostat to 78 degrees or higher
  • Turn off nonessential lights and electrical appliances
  • Avoid using large appliances like ovens or washing machines
  • Close drapes and blinds

Businesses were also asked to minimize electricity consumption and shut down or reduce "non-essential production processes."

The time period you should particularly abide by these rules is between 3 and 7 p.m. This is when the state sees peak electricity consumption.

Why Is There A Conservation Alert

Two events colliding together at the same time caused this conservation alert:

  1. An early heatwave is causing record June electricity demand.
  2. An unexpected amount of electric generating capacity was under forced outages for repairs. Around 11,000 megawatts (MW) of generation was offline, which is much higher than the average of 3,600 MW.

This caused the wholesale electricity market in Texas to spike to almost $2,000 per megawatt-hour (MWh) on Monday.

Why This Alert Is Getting So Much Attention

This past February, Texas faced a winter storm that caused millions to go without power for days in brutally cold weather. Lack of heating caused pipes to burst, which in turn caused water shortages.

Since then, ERCOT and the Public Utilities Commission of Texas (PUCT) have come under increased scrutiny for how the Texas electric grid operates.

More than that, events like these point out the vulnerability of America's infrastructure across the US, especially as climate change increases the number of these extreme weather events. For example, California's grid regulator also released an alert this week that suggested Californians be prepared to conserve energy and avoid power outages.
