Wyoming: official power outage sources

If your power is out

1. Stay away from downed lines and anything touching them. Call 911.
2. Report it to your own utility. The name and outage phone number are on your electric bill. Do not assume a neighbor has reported it.
3. Check your utility's outage page for the area affected and any restoration estimate. Only your utility can give that estimate.

Good to know in Wyoming

• Cooperative and city utility customers should check with their own provider; the big utilities' maps do not cover them.
• Rocky Mountain Power's outage page covers several states; check that a listed outage is in Wyoming.
• The Wyoming Rural Electric Association is a trade group, not a utility; contact your own cooperative.
• For local emergency help, use your county emergency management contact.

The wider grid

Regional grid organizations and balancing areas that cover all or part of Wyoming: PacifiCorp (PACE) balancing area; Southwest Power Pool (western expansion, April 2026); WAPA. They balance supply and demand on the high-voltage system. Their alerts describe the regional system, not an outage on your street. How the pieces fit together
