City of Burlington Electric, VT
This utility did not file a reliability report
City of Burlington Electric is one of only 12 utilities nationally that filed no outage-frequency or outage-length figures in the most recent federal reliability filing. That is a gap in the reporting, not evidence the grid in Vermont is reliable or unreliable - there is simply nothing filed to measure it against. Check the Vermont state figure below instead, or ask City of Burlington Electric directly for its own outage history before deciding on a generator.
