CMP Works to Restore Power Following Tropical Storm Isaias

Sixty percent restoration by Wednesday afternoon, more expected throughout the day

AUGUSTA, Maine — August 5, 2020 — Central Maine Power (CMP) crews are cleaning up roads and downed power lines and restoring power as a result of damages caused by Tropical Storm Isais, which caused millions of power outages across the east coast. Nearly 118,000 were impacted by Isais in Maine, including 92,000 at the peak of the storm, and CMP has already restored power to sixty percent of customers by Wednesday afternoon. As of 1:00 PM on Wednesday, about 46,000 customers were without power.

Working closely with local and state emergency management agencies, CMP was prepared to respond to the unique impact this storm had, with sustained winds of up to forty miles per hour, for up to four hours in certain areas.

“Our team has worked diligently to establish safe conditions, allowing our lineworkers to hit the ground running with restoration efforts,” said David Flanagan, CMP’s executive chairman. “Having both our internal crews and contracted partners prepared ahead of time allowed us to make significant progress in restoring power rapidly for many customers.”

In addition to about 200 CMP lineworkers, the company has approximately 240 contracted lineworkers, including 80 from New Brunswick, Canada, and 100 tree crews responding to the outages. More line crews are on their way from Hydro Quebec to assist with clean up efforts.

Restoration priorities:

  • CMP follows an orderly process when restoring service that emphasizes safety and seeks to make effective use of resources.
  • CMP’s immediate concern after a storm is public safety. Restoration teams work with towns and the state to de-energize downed lines, clear roads and restore previously identified critical facilities such as hospitals and shelters.
  • Next, CMP focuses on assessing damage and repairing the backbone of the electrical system: substations, transmission lines, circuits and primary lines. Crews focus on locations where they can restore large numbers of customers at once.
  • Then, crews restore equipment and lines that serve smaller groups of customers.
  • Finally, crews focus on restoring remaining service lines to individual homes and buildings until every customer has service. This phase may begin while higher-priority work is already underway.

CMP urges customers to never go near a downed power line, and to plan accordingly in the event restoration takes time.

CMP crews and contractors are also adhering to COVID-19 protocols that include appropriate social distancing practices for field employees and contractors including:

- Working in separate teams to minimize contact
- Restricting visitor access to company facilities
- Entering a customer residence only in the event of emergency and after assessing risk
- Maintaining appropriate social distancing in the field
- Allowing one employee per vehicle
- Wearing masks as situations require

Customers may use online tools, accessible at to report and monitor outages.

  • Keep sensitive electronic appliances such as computers, TVs and stereos plugged into a surge protector, or unplug them. They could be damaged if a power surge occurs when electricity is restored.
  • Keep refrigerator and freezer doors closed. For information about food safety, visit

For customers with generators:

  • Hire a licensed electrician to install permanent generators and transfer switches.
  • Properly ground all portable generators.
  • Carefully read and observe all instructions in your generator’s operating manual.
  • Never run a generator indoors, or even in an open garage.
  • If your carbon monoxide detector goes off – get out of the building immediately and call 911.
  • Do not store fuel indoors or try to refuel a generator while it’s running.
