Media Advisory for Valley Area -- Increased risk of rolling blackouts in Valley

Consumers urged to conserve to reduce necessity for outages

7:15 pm,  February 9, 2011 -- There is an increased risk that ERCOT may need to instruct Valley-area transmission and distribution service providers to drop firm load due to transmission import limitations in the area. This is a localized to the Rio Grande Valley area; it is not a state-wide problem.

ERCOT is asking consumers in the Rio Grande Valley area to reduce energy consumption this evening and during the morning peak hours to avoid the need for rotating outages, including:

  • Keep your thermostat as low as is comfortable.
  • Turn off and un-plug non-essential lights and appliances.
  • Avoid running large appliances such as washers, dryers, and electric ovens during peak energy demand hours.
  • 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.

These conditions are expected to continue through the night and into Thursday morning.

The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power to more than 26 million Texas customers -- representing about 90 percent of the state’s electric load. As the independent system operator for the region, ERCOT schedules power on an electric grid that connects more than 46,500 miles of transmission lines and 710+ generation units. It also performs financial settlement for the competitive wholesale bulk-power market and administers retail switching for nearly 8 million premises in competitive choice areas.

ERCOT is a membership-based 501(c)(4) nonprofit corporation, governed by a board of directors and subject to oversight by the Public Utility Commission of Texas and the Texas Legislature. Its members include consumers, cooperatives, generators, power marketers, retail electric providers, investor-owned electric utilities, transmission and distribution providers and municipally owned electric utilities.
