What to plan for in Concord
- Ice storms (relatively high): Ice storms bring down lines for days. A standby generator with a transfer switch, or a battery sized for the fridge, furnace blower and well pump, matters more than a small power station.
- Lightning (relatively high): Lightning causes short outages and damages electronics. Surge protection and a battery that switches over automatically protect the things you care about.
- River and heavy-rain flooding (relatively moderate): Heavy rain can flood basements and take out power. Put sump pumps on backup power and keep equipment above the flood line.

- City of Concord Code Administration (Building and Code Services): permit information

Choosing an installer
- License: check the contractor on the NH license verification and that the license covers this work.
- Quote: ask for an itemized written quote that names the equipment, warranties and who pulls the permit and handles the utility approval.
- Compare: get two or three quotes and compare them line by line, not only the total.
