With winter right around the corner, Oncor has finalized its preparations for the 2025–26 winter season. Crews and planners have spent months working proactively to minimize weather-related impacts and keep operations ready should cold snaps or winter storms arrive.

Oncor plans for winter year-round — anticipating everything from brief extreme cold to multi-day storm systems. For the 2025–26 season, work completed includes:

• Inspecting and servicing thousands of electric facilities, including substations and primary feeder lines, so equipment is available to meet higher load and colder temperatures. Crews also performed winter checks on hundreds of vehicles, including bucket trucks, to ensure they’re safe for winter driving and response.
• Using forecasting and predictive analytics to pinpoint potential high-load areas and prioritize targeted upgrades or equipment replacements before problems occur.
• Reviewing material inventories and confirming contract partners to maintain an uninterrupted supply chain for repairs and replacement parts.
• Verifying employee safety through routine personal protective equipment inspections and readiness checks so crews can operate safely in winter conditions.
• Conducting extensive emergency response and outage training so personnel can react quickly and safely if outages occur.

Oncor also remains in compliance with the Public Utility Commission’s winterization requirements under Senate Bill 3 and has submitted its annual Winter Weather Readiness Report for the 2025–26 season to demonstrate that equipment and procedures meet regulatory expectations.

As the company that owns and operates the “poles and wires,” Oncor does not generate electricity. Instead, it maintains close coordination with local officials, emergency managers and communities to support efficient responses to local needs during severe weather events.

Stay informed — customer communications

Oncor encourages customers to sign up for alerts and use its communications tools to stay informed during winter weather:

• MyOncor App (available on the App Store and Google Play)
• My Oncor Alerts (text REG to 66267 to register)
• Storm Center outage map on Oncor’s website
• Social media channels (Facebook, X)
• Customer service: 888.313.4747

For customers who rely on electricity for critical medical equipment or who represent critical public or industrial loads, information on designation options for Critical Care/Chronic Condition (residential) and Critical Load (non-residential) is available on Oncor’s website. Please note that these designations help prioritize support but do not guarantee an uninterrupted or continuous power supply.

Winter outlook for 2025–26

Oncor monitors both seasonal and short-term forecasts throughout the year. One climate driver the company continues to watch is La Niña, a pattern that can influence seasonal temperature and precipitation trends across the U.S. While seasonal guidance may suggest milder or drier conditions in parts of the southern U.S., winter weather is inherently variable — occasional cold snaps and winter storms remain possible.

Winter preparedness tips

Oncor recommends that customers take a few simple steps now to prepare for winter:

• Monitor local weather forecasts and alerts.
• Assemble or refresh a winter emergency kit with blankets, flashlights, extra batteries, and non-perishable food and water.
• Inspect home insulation and heating systems to help maintain comfort and energy efficiency during cold weather.

Oncor is committed to delivering safe, reliable service and to helping customers navigate whatever winter brings. Preparing early and staying connected makes a noticeable difference when severe weather arrives.
