ComEd Chicago Power Outage: Outage Map, Status, Reporting & Restoration Times

Last updated: October 15, 2026

A search for Chicago power outage today usually has a very practical purpose: you want to know whether the problem is already known, how large it is, whether your address is included, and when electricity may return.

Those questions are related, but they are not the same. A citywide outage map can show the scale of a problem, while an address-level status is more useful for determining what is happening at your specific home. And an estimated restoration time is an estimate, not a guaranteed appointment.

This guide explains how to use the official ComEd tools, how to interpret the information you see, what to do when your outage does not appear on the map, and how to plan backup power for a Chicago outage that lasts longer than expected.

How to Check a Chicago Power Outage Right Now

If your lights suddenly go out, use this order:

1. Check whether the outage extends beyond your home. Look through a window for nearby exterior lights, streetlights or neighboring buildings. Do not walk toward damaged electrical equipment or downed wires.
2. Open the official ComEd Outage Map. Use cellular data if your home internet is down.
3. Search your exact address. Address-level information is more useful than assuming every customer in your ZIP code or neighborhood is affected.
4. Check your individual ComEd outage status. Your account-linked status may provide information specifically associated with your service address.
5. Report the outage if necessary. Do not assume that a neighbor has already reported the same problem.
6. Save the estimated restoration time, then check again later. The estimate can change after crews inspect the site.

How to Use the ComEd Outage Map

The ComEd outage map should be your first stop when searching for a power outage in Chicago. It is more useful than a social-media post or a generic outage website because ComEd is the utility responsible for electric distribution across Chicago and much of northern Illinois.

1. Open the official map

Go directly to the official ComEd Outage Map.

2. Search your location

Use your street address when possible. The map can also provide broader summaries, including affected ZIP codes and Chicago wards, but your exact address is the better starting point when the question is simply, “Is my house part of this outage?”

3. Look beyond the customer count

A large customer number tells you the event is significant, but it does not tell you whether your particular electrical circuit has the same damage as another part of the neighborhood.

Two homes separated by only a few streets can sometimes be supplied through different parts of the local distribution system. One group may be restored before another even though both appear inside the same Chicago neighborhood or ZIP code.

4. Check the status and restoration estimate

If an estimated restoration time is available, treat it as the utility's current working estimate. Save it, but check again later because field conditions can change.

5. Check your address again after nearby power returns

If most of the block comes back on but your building stays dark, do not assume ComEd still knows your individual service is out. Recheck your address and report the continuing outage if needed.

Chicago Power Outage by ZIP Code, Ward or Address: Which Should You Use?

People often search for Chicago power outage by ZIP code or Chicago power outage near me. ComEd's map provides several geographic ways to understand an outage, but they answer different questions.

The official ComEd map includes outage summaries by county, cities and towns, Chicago wards and affected ZIP codes. For an individual customer, however, location-specific status remains the more useful check.

How to Report a ComEd Power Outage

If you are experiencing a ComEd power outage in Chicago, there are several ways to report it.

What does FULL or PARTIAL outage mean?

ComEd's text reporting process may ask whether you have a FULL or PARTIAL outage.

A full outage means the property has lost electric service completely. A partial outage can include symptoms such as some electrical service remaining, flickering or abnormal power behavior.

Partial power problems should not be ignored. Avoid repeatedly switching major appliances on and off, and report unusual electrical conditions to ComEd. If you smell burning, see sparking, hear abnormal buzzing from electrical equipment or see water around electrical equipment, keep your distance and seek qualified help.

How Long Does a ComEd Power Outage Last?

There is no single reliable answer to “How long will a Chicago power outage last?” A small localized equipment problem can be very different from a storm that damages trees, poles and multiple sections of the distribution network.

ComEd states that estimated restoration times can change based on what crews discover at the outage site. That detail matters because the first estimate may be made before the complete extent of the damage is known.

How to interpret a ComEd restoration time

Official source: ComEd outage reporting and restoration information.

Why can one Chicago neighborhood come back before another?

Power restoration is not simply a queue where the first outage reported is always the first outage repaired. Damage can occur at different points of the electrical system, and one repair may restore a large group of customers while another requires crews to replace or repair equipment serving a much smaller area.

That is why comparing your estimated restoration time with a friend a few blocks away can be misleading.

Why Does the Power Go Out in Chicago?

Chicago and northern Illinois face a combination of weather conditions capable of damaging electric distribution equipment throughout the year.

Recent severe weather shows why Chicago outage plans matter

The Chicago area does not need a hurricane to experience a large power disruption.

On July 27, 2026, the National Weather Service Chicago documented severe thunderstorms that produced tornadoes and extensive straight-line wind damage. Parts of southern Cook and eastern Will counties experienced estimated wind gusts of roughly 80–105 mph. Local reporting following the event said more than half a million ComEd customers lost power across northern Illinois during the storms.

On August 11, 2026, another powerful derecho produced widespread 70 to locally 100+ mph winds across parts of northeastern Illinois and northwestern Indiana.

These events show why a Chicago outage plan should account for more than a quick 30-minute interruption. Severe wind damage can involve trees, wires and poles across many repair locations at the same time.

What If Your House Has No Power but the ComEd Outage Map Shows Nothing?

This is one of the most useful distinctions to make during a Chicago electricity outage: is the problem on the utility system, inside the building, or only inside your unit?

Special note for Chicago apartments and condos

In a multi-unit building, an outage may affect:

• the entire neighborhood,
• only your building,
• only part of the building,
• or just one unit.

That is why an address-level ComEd check plus communication with the property manager is often more useful than looking only at a Chicago-wide outage count.

What to Do During a Chicago Power Outage: First 10 Minutes

Once you have confirmed the outage, your first goal is not to power every appliance in the home. It is to protect safety, food, communication and essential health needs.

1. Check for immediate hazards. Look for downed wires, fire, smoke, flooding or damaged electrical equipment.
2. Report the outage and check ComEd status.
3. Keep the refrigerator and freezer closed.
4. Charge or conserve your phone. Use low-power mode if the outage may continue.
5. Unplug unnecessary sensitive electronics.
6. Identify essential loads. Prioritize medical equipment, communications, refrigeration and basic lighting.
7. Check the restoration estimate. A two-hour outage and an overnight outage require different battery strategies.

For a more detailed timeline, see the UDPOWER 24-, 48- and 72-hour power outage checklist.

If you already have backup power but are not sure what to connect first, use the power outage priority guide for refrigerators, medical devices, Wi-Fi and essential loads.

How Long Is Food Safe During a Chicago Power Outage?

Food safety becomes important faster than many people expect.

According to USDA guidance, an unopened refrigerator generally keeps food safely cold for about 4 hours. A full freezer can hold a safe temperature for approximately 48 hours, while a half-full freezer lasts about 24 hours if the door remains closed.

An appliance thermometer is much more useful than guessing. Refrigerated food should remain at 40°F or below. Never taste questionable food to decide whether it is safe.

You can also use UDPOWER's portable power station refrigerator runtime calculator to estimate battery runtime at different refrigerator loads.

How Much Backup Power Do You Need for a Chicago Outage?

A useful outage backup plan starts with energy priorities, not with trying to reproduce normal household electricity use.

Most households can dramatically extend backup time by separating appliances into three groups:

Priority 1: Keep running

• essential medical equipment,
• phones,
• basic LED lighting,
• router and modem when the internet connection is still operating,
• refrigeration when needed to maintain safe food temperatures.

Priority 2: Run only when needed

• laptops,
• TV,
• fans,
• small kitchen appliances,
• additional lighting.

Priority 3: Avoid during battery backup unless necessary

• space heaters,
• high-watt cooking appliances,
• hair dryers,
• large resistive heating loads,
• anything that uses a large amount of electricity but provides little outage-critical value.

Watts and watt-hours are different

Watts (W) tell you how much power a device needs at one moment.

Watt-hours (Wh) tell you how much energy the battery stores.

For planning UDPOWER runtime in this guide, the calculation uses a 90% conversion-efficiency assumption:

Estimated runtime = Battery capacity × 0.90 ÷ average device watts

Actual runtime varies with appliance cycling, inverter load, temperature, battery condition and device behavior.

Recommended UDPOWER Power Stations for Chicago Power Outages

For a home outage, the most useful UDPOWER options are the S1200 and S2400. Both use LiFePO4 battery chemistry and pure sine wave AC output, but they serve different outage plans.

Best for Essential Home Backup

UDPOWER S1200 Portable Power Station

The S1200 is the better fit when your outage plan centers on a refrigerator, router, phones, lights, CPAP equipment, laptops and other selected 120V household essentials rather than trying to run an entire home.

• Battery capacity: 1,190Wh
• Rated AC output: 1,200W pure sine wave
• UDTURBO: supports compatible higher-power loads up to 1,800W when operating from battery
• UPS switching: ≤10 ms
• Solar input: up to 400W
• Weight: approximately 26 lb
• Battery chemistry: LiFePO4
• Battery lifecycle: approximately 80% capacity after 3,000 cycles and approximately 70% after 4,000 cycles

Best for Longer or Higher-Load Outages

UDPOWER S2400 Portable Power Station

The S2400 provides substantially more stored energy and twice the S1200's rated AC output, making it a stronger choice when you want longer refrigerator runtime, more simultaneous household loads or greater power headroom.

• Battery capacity: 2,083Wh
• Rated AC output: 2,400W pure sine wave
• Battery/inverter mode: supports up to 3,000W constant-power output for compatible loads
• UPS/bypass mode: applicable output limit remains 2,400W
• UPS switching: ≤10 ms
• Solar input: up to 400W
• AC outlets: 6
• Weight: approximately 40.8 lb
• Battery chemistry: LiFePO4
• Battery lifecycle: approximately 80% capacity after 3,000 cycles and approximately 70% after 4,000 cycles

Best Chicago outage use: extended backup for a refrigerator plus communications, lighting, electronics and additional 120V appliances when you want more runtime and output headroom.

To compare additional capacities, visit the UDPOWER portable power station collection or the home backup power station collection.

You can also compare these two models directly in the UDPOWER S1200 vs. S2400 guide.

Estimated S1200 and S2400 Runtime During an Outage

The table below uses the same simple planning method throughout:

Capacity × 90% ÷ average load

These are planning estimates rather than guaranteed operating times. Real appliances may draw more or less power than the examples above.

Which model makes more sense for a Chicago outage?

Summer vs. Winter Chicago Outage Planning

A Chicago backup plan should change with the season.

Summer outage priorities

• refrigerator and freezer temperature,
• fans,
• phone and communications,
• medical equipment,
• weather alerts,
• safe hydration and indoor temperature.

A portable power station can run a fan, but it should not be confused with a central air-conditioning backup system. If indoor temperatures become unsafe, follow local emergency guidance and relocate when necessary.

Winter outage priorities

• communications,
• medical equipment,
• safe lighting,
• pipe protection,
• maintaining a safe indoor temperature,
• a relocation plan if the home becomes dangerously cold.

The National Weather Service Chicago winter preparedness guidance notes that winter storms can knock out power and that ice storms can cause outages lasting several days.

Before the Next Chicago Power Outage

The best time to prepare is while the grid is still working.

• Save the official ComEd outage map in your phone bookmarks.
• Enroll in ComEd outage text alerts before a storm arrives.
• Know where your electrical panel is.
• Keep flashlights where they can be found in the dark.
• Keep refrigerator and freezer thermometers installed.
• Write down the wattage of the devices you consider essential.
• Charge power banks and portable power stations before forecast severe weather.
• Test your backup setup with the actual refrigerator, router, CPAP or other device you intend to use.
• Keep charging cables together with the power station rather than scattered around the home.
• Have a plan for outages that exceed your battery capacity.

For CPAP users, see the UDPOWER CPAP battery backup guide and product selection.

Frequently Asked Questions About Chicago and ComEd Power Outages

Bottom Line

When a Chicago power outage happens, start with the official ComEd map rather than a social post or an old outage count. Search your address, report the outage, monitor the restoration estimate and be prepared for that estimate to change as crews learn more about the damage.

For a short interruption, preserving phone battery and keeping the refrigerator closed may be enough. During severe thunderstorms, derechos, tornado damage or winter weather, however, an outage can become a much longer household problem. That is when a realistic backup-power plan becomes useful.

The goal is not to run everything. It is to keep the devices that matter most operating for as long as possible.
