Emergency Power Greenlit for Montana‑Wyoming Grid as Heat Wave Looms
Emergency Power Order Activated as Heat Wave Strains Electric Grid Across 17 States
What Happened?
The U.S. Department of Energy stepped in on Sunday with an emergency order covering 17 states — including Montana and Wyoming. This order allows the region’s main power manager to fire up backup generators to keep the lights on as a massive heat wave pushes electricity demand to near-record highs.
Important Point: This emergency order is the last step before a "Level 3 Energy Emergency Alert" — which could mean rolling blackouts to stop the whole grid from crashing.
Who Manages the Power?
The Southwest Power Pool (SPP) is the "traffic controller" for the electric grid across much of the central U.S. In Montana, they work with local cooperatives like Yellowstone Valley Electric Cooperative to keep power flowing to homes and businesses.
What Is a "Level 3 Energy Emergency Alert"?
Think of the grid like a highway. When traffic (electricity demand) gets too heavy, officials raise the alert level:
| Alert Level | What It Means |
|---|---|
| Level 1 | "Heads up — we’re watching closely." |
| Level 2 | "Things are tight — we’re using all normal tools." |
| Level 3 | "Emergency! We may need to turn off power to some areas on purpose (rolling blackouts) to save the whole system." |
Brandon Wittman, CEO of Yellowstone Valley Electric, explains: "A level three is where you start considering curtailing — that’s utility talk for cutting power on purpose."
Not All Outages Are the Same
Wittman wants people to understand: rolling blackouts are rare and very different from other outages.
Common Outages (Happen More Often)
- Public Safety Power Shutoffs — Planned outages during high fire risk or extreme winds
- Storm Damage — Trees falling on lines, lightning strikes
- Equipment Failure — A transformer blows, a line snaps
Rolling Blackouts (Very Rare)
- Last resort to prevent total grid collapse
- Controlled and rotating — not everyone loses power at once
- Require multiple stressors happening at the same time (heat + high demand + plant outages + low wind/solar, etc.)
Wittman says: "It’s going to take something more than just heat to cause an outage or a rolling blackout."
How Would Rolling Blackouts Work? (If They Happen)
If the grid gets critically stressed, here’s the step-by-step plan:
- Target large industrial users first — Think oil refineries, big factories, major facilities
- "You think about some of the really big industrial loads, the Billings area refineries… That’s where shedding load really pays off," says Wittman
- Identify specific neighborhoods or circuits — Not the whole region at once
- Rotate outages — Area A off for 1–2 hours, then restored while Area B goes off
- Keep critical infrastructure running — Hospitals, emergency services, water systems prioritized
Good News: "It’s not like it rolls across this entire region. They identify certain areas that’ll be most beneficial to start turning things off."
Why Is This Heat Wave So Dangerous for the Grid?
It’s not just the temperature — it’s how long it lasts.
| Factor | Why It Matters |
|---|---|
| Daytime highs | AC units run nonstop |
| Overnight lows stay high | Buildings, transformers, and power lines never cool down |
| Multi-day duration | Equipment fatigue + no recovery time = higher failure risk |
| Wide geographic area | Neighboring states can’t share extra power — everyone needs it |
Wittman: "It’s not just the one day of extreme heat. It’s the extended period that really makes a difference where things just don’t have the opportunity to cool down overnight and recover."
Regional Differences: Montana vs. The South
- Montana & Wyoming: Cooler than southern states, but still part of the same grid system
- Texas & Louisiana: Could see 110°F+ — putting massive strain on their grids, which are connected to the broader network
What Can You Do Right Now?
Simple Steps to Help the Grid (and Your Bill)
- Set thermostat to 78°F+ when home, higher when away
- Run big appliances (dishwasher, dryer, EV charging) overnight or early morning
- Close blinds/curtains on sunny windows
- Use fans to feel cooler without lowering AC
- Unplug unused electronics — they still draw "phantom power"
- Sign up for utility alerts — Get texts if conservation is critically needed
Summary
- Emergency order active for 17 states including MT & WY
- Backup generators authorized to meet record demand
- Level 3 alert = possible rolling blackouts (last resort)
- Big industry first if outages needed — not your neighborhood
- Long duration heat = bigger problem than single hot day
- You can help by shifting usage to cooler hours
FAQ
1. Will my power get shut off today?
Probably not. The emergency order is a preventive step. Rolling blackouts only happen if all other options fail. Even then, residential areas are last on the list.
2. What’s the difference between a rolling blackout and a regular outage?
A rolling blackout is planned, controlled, and rotating — utilities choose specific areas for short periods. A regular outage is unplanned (storm, car hits pole, equipment failure) and lasts until fixed.
3. Why target factories and refineries first?
One large industrial facility can use as much power as thousands of homes. Cutting them saves massive energy quickly with fewer customers affected.
4. How long would a rolling blackout last?
Typically 1–2 hours per area, then power rotates to another section. The goal is to share the burden so no one is without power for long.
5. Where can I get updates if things change?
- Yellowstone Valley Electric Cooperative (or your local utility) website & social media
- Southwest Power Pool alerts at spp.org
- Local news (MTN, Billings Gazette, etc.)
- Emergency alert systems on your phone
