After we received an inquiry by a curious member, the KWPOA has been in communication with PG&E as to why sometimes our power goes out when neighborhoods around us retain power.
We learned that Kent Woodlands is served by the San Rafael 1107 Circuit. This circuit traverses the Wolfe Grade and Laurel Grove neighborhoods across Sir Francis Drake Boulevard. Both areas are located in a Tier-3 High Fire Threat District. Because of this circuit, and Kent Woodlands being a High Fire Threat District, the circuit is protected by Enhanced Powerline Safety Settings (EPSS) which automatically turn off power within one-tenth of a second if an object such as a tree comes in contact with a powerline. These adjustments make PG&E's electric system safer for communities, but may also result in unplanned power outages due to how quickly the power lines turn off. If power is shut off due to a hazard, PG&E must check the lines for damage and potentially make repairs prior to restoring power.
Following KWPOA's recent inquiry, PG&E took data from seven transformers that serve our neighborhood and looked at outage frequency and cause over the last few years. Most causes they found were related to vegetation (PG&E recognizes that our neighborhood has an abundance of vegetation they look to manage each year) as well as animal related outages (such as birds and squirrels) due to EPSS, and then some equipment issues that may not have been within our community. They also found some “unknown causes” – this is usually where the outage is not equipment related, but the cause is not apparent, such as an animal or bird hitting the line and it cannot be found during assessments. Some are also planned outages for work taking place.
Recently, on May 8th, our power went out and those of us with kids in the Kentfield School District received an email before 8:00 a.m. that Kent Middle School would be closed for the day, yet Bacich Elementary School remained open, as this close-proximity neighborhood had power. When I asked about this incident, PG&E said this is what was called a “pothead” in the middle of the primary riser. It was replaced, so it is a permanent fix. PG&E said they experience some equipment failures over time which is normal, but they have seen more frustration over outages because they have also enabled the EPSS settings so with an uptick in safety outages (which can be longer as well, due to the requirement they survey before turning the power back on) the more routine equipment replacements and planned projects become more of nuisance.
For now, I find it helpful that the KWPOA is now in regular contact with PG&E to insure they stay hyper-focused on Kent Woodlands.
Heading into fire season, this is a good reminder to stay prepared for outages. Visit this link for more information on outages and preparedness:
