PUD Outage Report - 12/20/2022

The following announcement is from Jefferson County PUD and is brought to you as a public service of the PLVC Utilities Committee
<https://imgssl.constantcontact.com/letters/images/PT13966/CustomDivider.png>
The PUD Board of Commissioners conducted a Special Meeting on December 20th. One of the agenda items was an update on Port Ludlow’s recent power outages. The PUD Board of Commissioners
and senior management are aware that power outages are a tremendous inconvenience to their customers and discussed ways to address the problems in the short and long term.
Background: Power to Port Ludlow is delivered via transmission lines down Beaver Valley Road to the Port Ludlow Substation. Service is then divided into multiple “feeders,” supplying
power to different sections of the greater Port Ludlow area, which extends down Beaver Valley and Oak Bay Roads to Highway 104 and then south through Shine and Bridgehaven and Thorndyke.
At this time there is no back-up transmission line to supply power to the Port Ludlow substation and community. When a car knocked down a transmission pole this past Friday night, power
was lost to the entire area and could not be restored until the pole was fully removed and replaced, a job that took more than 12 hours.
Similarly, when a fallen tree led to a catastrophic fault in Port Ludlow’s 1960s-era substation transformer, power was lost to the entire area and couldn’t be fully restored until the
transformer was replaced. Luckily, PUD staff had a spare transformer on site, and the job was completed in less than 24 hours, though it required a heavy-duty crane from Kitsap to complete
the work. See picture below:

From a positive point of view, Port Ludlow residents were extremely lucky that there was a replacement transformer on site. If not, the time to restore power would have taken much more
time. As a point of information, the cost of a substation transformer is approximately $750K and it takes a year to manufacture one.
During both outages, the PUD was able to restore some areas by switching distribution lines to connect to those powered by the Chimacum Substation. However, distribution lines have much
less capacity than transmission lines. During cold weather, when demand for power is high, capacity is at its lowest. Winter mornings are peak times for electrical consumption in Jefferson
County. This is when capacity (or excess capacity) is at its lowest. When Ludlow area residents lost power for another few hours the morning after the substation transformer was replaced,
this occurred because our Chimacum Substation ran out of capacity to hold the extra Port Ludlow customers it had picked up in the middle of the night (a relatively low demand time).
In order to avoid losing all customers on the Chimacum Substation, the Ludlow customers were shut off until the new transformer had finished warming up and was ready to handle its intended
duties.
According to PUD GM Kevin Streett, more work on the replacement substation transformer is still needed. The PUD is planning another short outage of approximately two hours in duration
sometime during the next few weeks to complete the servicing of the replacement transformer. Customers will be notified well in advance of this planned outage. The PUD is planning on
doing this work when the temperatures are not quite so cold.
Long term over the next few years, the PUD is planning on adding a second substation transformer and a new circuit to improve the power reliability to Port Ludlow.
