Rolling Power Outage Information

ROLLING POWER OUTAGES (BROWNOUTS) - WHAT MEMBERS SHOULD KNOW

Consumers Energy works hard to provide reliable electric service in a safe manner at affordable and equitable rates. While outages are rare, there are times when temporary, controlled service interruptions - sometimes called rolling power outages or brownouts - may be necessary to protect the electric grid.

WHY WOULD ROLLING OUTAGES HAPPEN?

During periods of extreme high or low temperatures, electricity use can increase significantly across large regions. At the same time, there may be constraints on the amount of power available for the regional grid.

In these situations, regional grid operators such as the Midcontinent Independent System Operator (MISO) may direct utilities to temporarily reduce demand in order to protect the electric system from widespread damage or prolonged outages. Rolling outages are used only as a last resort to help maintain overall grid stability.

WHAT TO EXPECT
  • Service interruptions would be brief and temporary.
  • Outages would occur in rotating areas to share the impact fairly.
  • The goal is to prevent a much larger, longer-lasting outage affecting more members.
HOW WE PREPARE

Each year, Consumers Energy works closely with our generation and transmission power provider to prepare plans in case rolling outages are necessary. We maintain a rotating list of service areas that would guide how outages are implemented if directed by the regional grid operator.

These plans are designed to:

  • protect the electric system
  • minimize disruption
  • ensure the process is handled safely and equitably

We understand that any interruption of service is inconvenient, and we do not take these measures lightly. If rolling outages become necessary, we will communicate updates as quickly as possible through our website and other communication channels.

WHAT CAN I DO TO PREPARE?

While power outages are rare, being prepared can help keep you safe and comfortable if one does occur. Simple steps like assembling an emergency kit, knowing how to report an outage, and having a plan for your household can make a big difference.
