Santa Clara County sheriff’s deputies continue to investigate a commercial burglary at the PG&E Metcalf substation in Santa Clara County.
PG&E spokesman Brian Swanson said someone broke in and stole construction equipment from the station in the 100 block of Metcalf Road early Wednesday morning.
PG&E and the sheriff’s office are asking the public for information about the theft.
PG&E officials said the cause of the security breach appears to be human error. Fence detection alarms went off but substation security personnel did not appropriately address them, utility officials said.
There was no impact to the electrical grid, no equipment damaged and no customers lost service, according to PG&E.
Officials said intruders were able to access the substation site, but they didn’t try to disrupt the electrical grid.
The burglary occurred at the same station where shots were fired on April 16, 2013, during an apparent sniper attack.
Law enforcement officials said one or more shooters fired rifle shots at tanks containing oil used to power machines.
The shots caused 52,000 gallons of oil to spill out and put 17 of the 23 transformers at the station out of commission.
Following the 2013 incident, PG&E announced new security measures were being taken at the site, including additional fencing, intruder detection systems and improved lighting.
Anyone with information on the break-in is asked to call the Santa Clara County Sheriff’s Office.
