Authorities are investigating why five buildings, including SDG&E's company headquarters in Kearny Mesa, have been targeted in a string of shootings since January.
SDG&E officials said shots were fired on April 17 and May 8 at buildings at the headquarters at 8330 Century Park Court.
In all of the shootings, no one was injured, officials said.
“We are actively participating with law enforcement on their active investigation and remain focused on the safety of our employees,” the SDG&E statement said.
SDG&E officials declined to provide further comment, citing the active investigation.
Police said a 7-Eleven convenience store had shots fired in January and again this past weekend, and a ResMed office also had reports of shots fired earlier this spring.
Investigators believe all the shootings are related. They happened during early morning or late evening hours and don't appear to target any people.

The suspect is believed to be shooting the businesses from a car and the incidents are believed to be random acts of vandalism.
"We want anyone who's responsible for this to know they're facing some very serious charges and it could be much worse if someone were to get hurt," said San Diego police Lt. Scott Wahl.
Police have very little suspect information. On two occasions, witnesses reported seeing a four-door sedan speed off ffrom the area.
