Outage Information

CMLP has implemented an outage management system that will help us to restore power more quickly and provide more timely information to customers during emergencies. 

View a map of Concord with current outage information. The outage web map does require Silverlight, and it is accessible from non-windows computers with Firefox, Chrome and on smart phones like iPhone too.

For customers that want to be able to go to the map with a mobile device, you can link to it from the Commonwealth Connect (SeeClickFix) smartphone application.  

Outage Management

This system will enable CMLP staff to input customer reports of outages, which the software system will quickly group by location and analyze to predict electric system problems.

Geographic Information System 

The software is integrated with our Geographic Information System so it can access highly-detailed geographic images and technical data about the local electric grid. The new system will enable us to post up-to-date outage maps online and will provide more detailed outage location information that our staff can share with customers who call.
