Gateway Pundit’s report was Thousands Lose Power After Three Substations Sabotaged in Tacoma, Included were quotes from Seattle Times.

Deputies arrived on scene and saw there was forced entry into the fenced area. Nothing had been taken from the substation, but the suspect vandalized the equipment causing a power outage in the area. 

Deputies were notified of a second burglary to the TPU substation at 8820 224th St E which also had forced entry with damage to the equipment. Nothing was taken from this site either.

At 11:25 we were notified by Puget Sound Energy that they too had a power outage this morning at 02:39 am. Deputies are currently on scene at this facility where the fenced area was broken into and the equipment vandalized.

At this time deputies are conducting the initial investigation. We do not have any suspects in custody. It is unknown if there are any motives or if this was a coordinated attack on the power systems.

In total, three sites were vandalized, two TPU and one PSE, with more than 14K customers effected

One tweet said: “Not yet clear who did this, but there have been a lot of attacks on the power grid lately and it is something domestic terrorists, especially white supremacists eco-terrorists,  are obsessed with (and several have been convicted in connection with recent attacks/plots).”

I applied the correction based on the consensus of commenters who suspect eco-terrorists of a new tactic replacing their previous valve-turning exploits.
