CA-PG&E PSPS

PG&E held a teleconference this afternoon at 12:30. A few highlights below:

· All power from the de-energization should be restored by 1800 today.

· The PSPS event expected for the Sierra Foothills is likely to be limited to Butte County, specifically the Paradise area. However, PG&E is not committing to this location at this time. Technically speaking, they are not letting Placer off the hook quite yet.

· We will get another update at 5:30 pm.

My local steel supplier in Oroville was closed today due to the shutoff. They run a huge shop, with dozens of employees, and many local fab shops rely on their daily deliveries for their projects. This shutoff has a lot of secondary impacts.

PG&E held a teleconference this evening at 6:00. A few highlights below:

· Foresthill will be de-energized tonight sometime after midnight (this was our first notification) for a weather event through 10:00 am, with the hope of a 12-hour re-energization timeline.

· PG&E may call an audible and cancel the event around midnight.

Tonight’s power outages from KCRA

…and the winds in my yard in Foresthill 1/2 mi from where the transmission lines cross the NF canyon during the 13 hour ‘extreme weather event’ PSPS: Absolutely dead calm – hardly a leaf twitching, let alone tree swaying. :confused:

What is your “normal” wind speed and direction for that time of day?

Typical diurnal winds, with cooler air flowing down canyon (out of the NE) in the early morning through mid-day hours when there is sufficient gradient following the lifting of the inversion from the prior evening, with typical speeds in the 5-25 knot range.

This morning had minimal gradient at my elevation (~2500’), with a gradual warm-up to the mid 80s and uncomfortably humid RH locally, hitting peak temps about the time power was restored (just before 1600), and amusingly, the breeze started to kick in right about then as well, with gusts of up to 15knots at the canyon rim.

So there seems to have been some sort of a phenomenon which affected your “normal” weather?

All customers restored as of 12:00 9/26

Any idea what happened to the map that showed the potential PSPS areas?

In blue or green surrounded by some neon color, I forget?

Either I can’t find it now, or it hasn’t been generated.

I see a static map with numbered zones and a weather map with wind blowing around but not the Google based map that was posted by them the last couple of times with specific areas highlighted.

Area of concern is roughly from Bangor north up thru Shasta/Plumas/Tehama county lines

Last night PSPS

Sounds like over 1 million people will be affected later this week.
