ERCOT issues Energy Emergency Alert — conditions improving

AUSTIN, TX, Jan. 6, 2013. – With cold temperatures and high electric use this morning, the Electric Reliability Council of Texas (ERCOT) has announced an Energy Emergency Alert and has implemented the first two stages of its steps to protect the grid. 

“We have brought on all available electric generation and have deployed all demand response programs that have contracted with ERCOT to reduce electric use in emergency situations,” said Dan Woodfin, ERCOT director of System Operations. “Conditions appear to be improving at this time, and we do not expect to implement rotating outages this morning.”

Here are some ways to help until operating reserves are restored to target levels.:

·         Keep your thermostat as low as is comfortable, preferably no higher than 68 degrees.

·         Turn off and unplug non-essential lights and appliances.

·         Avoid running large appliances such as washers, dryers and electric ovens during peak energy demand hours (6-9 a.m. and 4-8 p.m.).

·         Close shades and blinds at night to reduce the amount of heat lost through windows.

·         Businesses should minimize the use of electric lighting and electricity-consuming equipment as much as possible.

·         Large consumers of electricity should consider shutting down or reducing non-essential production processes.

Power Warnings are issued by the regional electric grid operator, the Electric Reliability Council of Texas (ERCOT), when there is a likelihood that rotating outages will be needed to reduce load .

Rotating outages are controlled, temporary interruptions of electrical service initiated by each utility when supplies of reserve power are exhausted. Without this safety valve, generators would overload and begin shutting down to avoid damage, risking a domino effect of a region-wide outage.

Rotating outages primarily affect residential neighborhoods and small businesses and do not typically include critical-need customers such as hospitals and nursing homes.

The outages are typically limited to 10-45 minutes before being rotated to a different neighborhood. Some customers may experience longer outages if power surges cause equipment failure during the restoration process. Customers can minimize power surges by turning off appliances, lights and other equipment, except for one task light to determine when power has been restored.<>.
