What to plan for in New Carrollton
- Winter weather (very high): Winter storms and cold snaps combine outages with heating demand. Plan for the furnace blower or heat pump, not just lights, and keep a fuel supply you can reach in snow.
- Lightning (very high): Lightning causes short outages and damages electronics. Surge protection and a battery that switches over automatically protect the things you care about.
- Heat waves (relatively high): Heat waves strain the grid just when air conditioning matters most. Decide what must stay cool, such as one room, medicine and the fridge, and size backup to that rather than the whole house.
