Rancho Park, CA · March – June 2021 · LADWP / LADBS

Rancho Park: the file nobody could open.

The photographs the utility asked for were sent the same morning. They were sent as links, and the reviewer hit a password prompt.

Utility reviewers work inside their own network and mail system, and a shared cloud link from outside it frequently lands them on a sign-in page they cannot get past. Large attachments are rejected at the other end for a different reason. On this Rancho Park project the photographs for the meter spot went first as links that could not be opened, then as attachments split across two messages to stay under the size limit — and the assessment completed the same day. Cali Energy has sent utility documents as attachments since this 15.5 kW project in Rancho Park, Los Angeles.

The story

Fifteen and a half kilowatts on a Westside house, with an underground service. The plan set went out on the twenty-second of March and the interconnection request was acknowledged four days later.

On the thirtieth the service planning representative asked for photographs of the meter location. That is an ordinary request and it was answered within the hour.

It was answered with links. Shared folder, one click, everything in one place — the way anybody would send a dozen photographs to a colleague.

The reply came back in a sentence: the files would not open, the page was asking for a password.

This is worth understanding because it costs projects days and nobody writes it down. A reviewer at a utility is working inside their own network, on their own mail system, with their own security policy. A link to a shared folder in somebody else's cloud account frequently lands them on a sign-in page, and there is no version of that story where they create an account to look at your photographs. From their side the request simply has not been answered.

The fix is not clever. The photographs went again as attachments, and because a dozen full-size images in one message is the other way to get silently rejected, they went in two messages rather than one. The acknowledgement came back the same day, and the site assessment for the work request was recorded complete that afternoon.

The interconnection agreement was approved on the first of April.

What happened next is the ordinary shape of a larger system, and it is worth setting out because it is invisible from outside.

The plan check did not go over the counter. In this city a system from about thirteen kilowatts upward is normally routed to regular plan check instead — a queue rather than a counter, with an assignment backlog that ran to roughly twenty business days from the moment the fee was paid. Nothing was wrong with the drawings. The system was simply over the size where a permit can be issued while you wait, and that single fact decides whether a project like this takes days or months.

The corrections themselves were narrow and technical. The AC combiner box had to carry an interrupting rating at or above the available fault current at that service — twenty-two thousand amps — and the way that figure was written on the drawing had to be corrected as well. Two items, on a set that had been through review for weeks.

Add to that a rule of the period: a hard-copy set dropped at the counter sat through a forty-eight hour hold before a reviewer could open it, so each round trip cost two days before anybody looked at anything.

The drawings were revised and reissued through May, the installation was approved on the fifteenth of June, and permission to operate came the following day.

Two practical things, and the first one costs nothing to adopt.

When an agency asks you for a document, send the document. Not a link to it, not a folder containing it, not a viewer that needs an account. Attach it, and if it is too large, split it across two messages and say in the first one that a second is coming. It feels clumsy and it is the only version that reliably arrives.

The second is about underground service. Where the meter can sit on a house fed from below is a narrower question than on an overhead service, and it is settled with photographs of the actual location rather than from the drawing. That is why the request came, and why answering it in an hour rather than a week mattered.

Cali Energy designed, permitted and interconnected this 15.5 kW array in Rancho Park, Los Angeles, and sends utility documents as attachments because of this project.

How it ran

Approval and permission to operate one day apart. The day that mattered was in March, and it turned on how a dozen photographs were sent.

What we did

• Answered the photograph request inside an hour.
• Resent everything as attachments the moment the links failed, without arguing.
• Split the attachments across two messages to stay under the size limit.
• Revised and reissued the drawings through May against the corrections.
• Closed approval and permission to operate a day apart.

System specifications

Is your project like this one?

• An agency has asked you for documents and says it never received them.
• You have been sending files to a utility as shared links.
• Your service runs underground and nobody has settled where the meter goes.
• A large system came back with corrections and you want to know what that costs.

Frequently asked questions

Why could the utility not open our shared link?

Because reviewers work inside their own network and mail system, under their own security policy, and a link to a folder in an outside cloud account usually lands them on a sign-in page. They are not going to create an account to see your photographs. From their side the request has simply gone unanswered, and the project waits without anybody knowing why.

What is the right way to send documents to a utility?

As attachments. If the set is too large for one message, split it across two and say in the first that a second is coming, so nothing looks truncated. It is clumsier than a link and it is the version that reliably arrives, which on a project waiting for a site assessment is the only thing that matters.

Why does an underground service change where the meter can go?

Because the service comes up from below rather than in from a pole, so the position is constrained by the route of the conduit and by what the crew can reach and work on. It is settled against the actual site rather than the drawing, which is why the utility asks for photographs of the location before it agrees.

Why did my solar permit go to regular plan check instead of over the counter?

Usually because of the system size. In Los Angeles a residential system from about thirteen kilowatts upward is normally routed to regular plan check rather than the counter, which means a queue and an assignment backlog rather than a permit while you wait. Nothing is wrong with the drawings; the project is simply over the threshold where same-day issuance applies.

Does Cali Energy install larger systems in Rancho Park, Los Angeles?

Yes. This Rancho Park project was 15.5 kW AC-CEC on an underground service, permitted through LADBS and interconnected through LADWP like the rest of the city. Larger systems on the Westside usually turn on the service and the meter position rather than on the roof.
