September 9, 2024 (San Diego) – At least 14,000 SDG&E customers across San Diego had power outages yesterday afternoon, left sweltering in triple-digit heat.

The majority of those outages were due to a problem at a substation in Rancho San Diego, which was likely caused by the extreme weather conditions, according to SDG&E communications manager Alex Welling,Times of San Diego reports.

Extreme heat causes wear and tear on infrastructure equipment and the power grid.  A key issue yesterday may have been numerous households running air conditioning overnight, since low temperatures remained uncomfortably hot in many areas.

Fortunately, power to most customers was restored within a few hours, as SDG&E crews toiled through the heat to make repairs.

How can you prepare for future outages during high heat?  Here are some tips.
