Bahamian utility companies do provide electricity to homes located in Harbour island, however electricity outages are not uncommon and can be frequent specifically when the island operates at full capacity.

Owners that can afford it, invest in generators that are turning on as soon as the on grid capacity shows signs of weakness. Generators are expensive and they should be calibrated to provide current for the whole house, a generator could cost up to $ 50 000. Home seekers should always ask if the house is properly equipped. Internet and wifi will of course be impacted when the electricity is interrupted and this even for homes that have generators, some owners also provide hotspots devices for wifi back up.
