Dive Summary:

• A Pacific Gas & Electric (PG&E) power substation was hit with gunfire early Tuesday morning in what it deemed an act of vandalism; PG&E spokesman Jason King said the gunshots caused cooling oil to leak from the substation.
• The California Independent System Operator (ISO) issued a "Flex Alert" to electricity consumers in Northern California, asking them to conserve energy as the region's transmission capabilities may be affected.
• ISO spokesman Steven Greenlee said outages could occur if end-users do not follow the conservation warning; Greenlee could not say when the substation would resume service, noting that replacing transformers "takes a while."
