Gaza's only power station has been shut down, cutting electricity in the area by almost two thirds.
The region usually relies on fuel smuggled in from Egypt, but the power facility has run out. The Gaza Strip is under a sea and land blockade imposed by Israel, which prevents regular shipments of power to the area.
Gaza's energy authorities say they will now only be able to give each household six hours of electricity at a time.
