To accomplish the repairs, crews have to turn off power for several hours in neighborhoods such as Ocean View Hills in the South Bay.
That means air conditioning units, fans, security systems and everything that runs on electricity won't work.
This is a worry when you consider temperatures will still be high even when the night-time work is planned.
At least four outages are scheduled in various parts of the county, most will last about eight hours, enough time for food to spoil in refrigerators.
That's why SDG&E is asking people to keep fridges closed as long as possible to keep things cool inside.
A company spokesperson says they hope people understand the work is critical and key to keeping unplanned outages from taking place.
"We've been monitoring the forecast... nothing has changed we're expecting moderate temperatures to complete the work," said SDG&E's Amber Albrecht.
One resident is not taking chances, he's not spending the night in a warm house.
"We're going to leave the house, we're going to a casino for the whole evening, have dinner and stay in the air conditioning," said Larry Wallace, Ocean View Hills resident.
