Eversource, formerly known as Public Service of New Hampshire, provides an official power outage map on Eversource.com. The map includes a color-coded range of customer outages and detailed reports by town.
Customers can access the map by going to the Eversource home page, choosing Residential or Business, and then clicking on Outage Map under Outages. Customers must enter a ZIP code when prompted.
On the map, purple shows outages affecting more than 20,000 customers, red shades highlight outages impacting more than 5,000 customers, and orange shades show outages connected to more than 500 customers, as of August 2015.
Eversource serves the areas previously held by PSNH, Connecticut Light and Power, Western Massachusetts Electric, Yankee Gas, and NSTAR Electric and Gas.
