    PSE

    Another one of my off-base requests.

    I'm been tasked to reach someone clueful on expansion issues at a residential Puget Sound Energy customer's site. (Albeit a bigger user than most one: the bill I'm looking at is for 7800 KWH.)

    The folks on-site there have not been able to get past the customer service firewall to someone with actual clue. (This sounds a lot like PEPCO here...) I looked for something like PG&E's Greenbook but have not found anything.

    I need the person I'd get if I could say "shibboleet" (re: XKCD])

    A PM is fine if you want.

    Folks who are personal friends are all retired from PSE so have no inside source, but,

    Surprised you cannot find what you need on PSE website, but they have revised part of the site recently.

    Had no problem 6 years ago adding another 200A service to a customer's house (much easier than upgrade and long feeders) PSE pulled the 175 ft of 4/0 service (my trench) low flat fee, forget what it was then.

    If your 7000 kW-hr resisdence is multi-family, lots of grnts for energy efficient goodies (gets tacked onto everybody else's bill here). I got a new HPWH for own house for just the sales tax.

    What is involved in 'expansion'? A new wing on apt building? 7000+ kw-hr implies a 5 unit apt building.. PSE installed just a single 37 kW distribution transformer for the last HFH 5 unit building (electric kitchen but gas heat) I helped .

      Thanks for the response.

      You could say multifamily:

      4 humans
      3 dogs
      2 cats
      12+ koi in 20,000 gal pond
      2 plug in electric cars
      2 GSHP's
      1 Endless pool.

      Expansions include those last three line items, but also gridtie solar. Did I mention the machine shop?

      We can trench the 300 ft route [1] but the last 15 ft go under the house somehow. Guess 811 will know where.

      Don't want to jinx myself, but gave up on main part of web page and found a map listing various PSE projects. Chose the one closest and bingo - name and phone of project boss. Called him, he answered, we talked, I sent him all the data. Have not heard back yet but it's hopeful.

      I'm in the DC area trying to avoid getting run over by an Abrams, but will be on-site there on Friday. I found imagery of the new meter expansion:

      with CT's but can't tell enough from it.


      1] I worked on his last house build; 1400 ft of 4" for PG&E, some of it getting winched up a slope too steep for the Ditch Witch.

        I like your use of the word Firewall but I would go more extreme if not for want to remain moderate in a public venue....

        Is it not interesting and also very telling that so many persons sit behind telephones, and computer consoles in large office buildings, AND
        Draw a paycheck
        Do not get anything useful done
        Obstruct things
        Do not have the slighest idea whats really going on in the real world
        And so forth.
        The exact same kind of compartmentalization mentality seemingly raining down from above is what creates all the useless technology that " does not perform " and that so many have taken as normal somhow. I am speaking about the devices and gadgets that waste tons of your time every day, that did not formerly exist and that we could for sure do without.
        Its a sign of the times. If Tradesmen got on the same page, and were truthful about things and started saying no En Masse, things could start to change.

          Update:
          Like most firewalls, it's soft on the inside.

          Found a name, who referred us to the Tacoma construction office, and after the GC visited there yesterday, today a lineman stopped by.

          We have 360+ ft of 350MCM from a 37.5KVA oil cooled pad xfmr feeding into the CT box.
          It runs under the garage, it appears, TBD.
          I would have assumed something bigger than that but...

          If necessary, we discussed paralleling with another run, or extending the HV and putting a transformer at the house.

            Here's the update on my PSE saga.

            After the lineman visit, 10 days later got Metering to come look in the CT compartment. We have 200A CT's.
            Then I got a Project Coordinator assigned. He visited the site and we soon locked on the big issue.

            The house is {roughly} Z shaped. The * is the CT-fed meter; inside that wall is the CT case.

            811 confirms the route from the case, from under the house's inside corner and then SE as shown by the diagonal marks. The PC said current PSE standards would not allow that. Plus, that inside corner is now covered by a deck.

            The line to the transformer may be direct burial past the elbow, or in DB120 conduit; we donno yet.

            We clearly need to replace the existing 350MCM with 700+MCM cable. How is the issue.

            If the 3" sweep elbow continues from the CT case in conduit to the porch edge, we could trench from the transformer to the porch edge, and PSE could pull in 700+MCM. But that's a big IF.

            The upper leg of the Z has crawl space beneath it but PSE won't allow a route right under it.

            I'm not anxious to go digging for the 240v feeder not knowing if it's in conduit or directly buried. Our current {err} plan is to have PSE pull power at transformer, open their meter cabinet and we'll slide a fiberglass snake down the conduit to see how far it goes. If there's an hope of reaching the end, we'll dig/drill each side of the marked route then carefully join the holes to expose the line.

            Plan B is a bore from the meter, under the crawl space and deck into the yard.

            Plan C is to abandon the existing route, go straight north from the meter location, bore under a driveway, & have PSE place a new pad-mount xfmr there. Dig a 18" by 48" trench 300 ft from it west to that road's primary run.

            Did I mention the septic field we're avoiding?

              So I've been through many hoops.

              Looks like it's Plan C for this. It will involve a 550 ft long 2" boring job, if PSE will extend from the last existing transformer. They're not yet sure.

              I'm calling around seeking boring companies interested. (Found one NOT, they are busy with a 3000' long, 19' diameter one. Gulp.)

              One question for the brain trust here. The PSE handbook shows terminals as seen below. I've searched under many nouns to no avail; where might I find them?

                I always enjoy driving past a place on the highway where they're drilling under the road.

                      Interesting transformer size.

                      By comparision I have a 50 kVA pole transformer. This supplies two street lights, my next door neighbor, and me. My average consumption is about 1.5 kW, seldom do I hit a peak of 6 kW. My neighbor is probably about the same.

                      Low source impedance at the transformer, but wimpy wires from it.

                      .

                        Well, that was what I understood PSE to say when he opened it.

                        It feeds two houses.It's 350 ft from the house. The feed is 350MCM.

                        The new xfmr will be fed from a different direction and is 550 ft away; but that's primary length. Secondary will be ~60 ft. long.

                          Found out the term for the insulated terminals above is "landing pads"..... No wonder I could not find them in catalogs.
