- Lucas: So there's a municipal utility in the Pacific Northwest — I'm not naming them because they're still mid-rollout — that had a problem a lot of utilities have right now. Residential solar applications were piling up. Homeowners who installed panels were waiting 83 days on average to get permission to flip the switch and actually export power to the grid. Luna: Eighty-three days. That's almost three months. Meanwhile the panels are sitting there generating power they can't sell back. Lucas: Exactly. And the utility knew it was bad. They surveyed customers and found that over half said the wait was the most frustrating part of going solar — more than the cost, more than the contractor experience. So they did something pretty smart. They mapped the entire approval process and found one bottleneck that accounted for 70 percent of the total cycle time. Luna: One step? What was it? Lucas: A manual review by a master electrician. Every single application — whether it was a straightforward four-panel system on a south-facing roof or a complicated three-inverter setup with battery storage — had to be individually reviewed and stamped by one of three licensed master electricians on staff. Those electricians had other duties, too. They inspected substations, they did field work. So applications sat in a queue for weeks. Luna: So the fix was to stop treating every application the same way. Lucas: Exactly. They built a tiered review system. Tier one: simple systems under 10 kilowatts with no battery, no unusual equipment. Those got an automated check against a set of rules — inverter model is approved, panel count matches the permit drawing, breaker size is correct. If the software flagged no issues, the permit was auto-approved. Luna: What percentage fell into tier one? Lucas: About 80 percent. So four out of five applications now never touch a human. They get approved within minutes. Tier two is systems with batteries or slightly larger arrays — those still get a manual review, but a trained permit technician handles it, not a master electrician. The electrician only touches tier three — complex systems, flagged safety concerns, or anything that fails the automated check. Luna: So the master electrician's time is now reserved for the edge cases that actually need their expertise. Lucas: Right. And the result after three months: average approval time dropped from 83 days to 14. They're still working on getting it under 10, but 14 is already a massive improvement. Customer satisfaction scores on the solar process jumped from 3.2 out of 5 to 4.6. And the utility didn't add any staff. Luna: No new hires? So this was purely a process redesign. Lucas: Purely. And the interesting thing is, the rule set for tier one wasn't that complicated. They just looked at the past three years of approved applications and identified the patterns that never had issues. Then they coded those patterns into the software. It's basically a checklist that runs automatically. Luna: That's the kind of thing that seems obvious in hindsight, but most organizations don't do it because they've never actually measured where the time goes. Lucas: That's the key. They measured. Before the change, they knew the average was 83 days, but they didn't know the breakdown. After they mapped it, they saw that the master electrician review alone took 58 days on average. The rest of the process — application intake, drawing review, final approval — took the other 25. So they focused on the 58-day chunk. Luna: And they didn't try to make the electrician faster. They removed them from the equation for most cases. Lucas: Exactly. Speed up the bottleneck by reducing its load, not by pushing the person harder. That's a classic operations principle, but it's hard to execute because it usually means changing who does what work. And that can be politically tricky inside an organization. Luna: I imagine the master electricians themselves might have been skeptical. 'You're going to let a computer approve electrical work?' Lucas: That came up. The utility's engineering manager told me they had to run a pilot for three months where the automated approvals were still double-checked by an electrician before going out. After those three months, the electricians saw that the automated system had a zero percent error rate on the tier-one applications. Zero false positives, zero missed issues. That built trust. Luna: And now the electricians get to work on the genuinely hard cases instead of stamping routine four-panel systems. Lucas: Which is more interesting work for them, by the way. The utility said turnover among the master electricians actually dropped after the change. They felt more valued because they were solving problems instead of doing data entry. Luna: So the operator lesson here is: find the step in your process that accounts for the most time, and ask whether every item really needs that step. Lucas: That's it. And be willing to let go of the idea that expertise is required for every touch point. Expertise is scarce. You want it applied where it adds value, not where a rule set can do the job. Luna: This also applies way beyond utilities. Any regulated approval process — building permits, insurance claims, loan underwriting — has the same dynamic. Lucas: Absolutely. In fact, I've seen versions of this in hospital credentialing, in government grant reviews, even in some software deployment pipelines where a senior engineer has to sign off on every code merge. The pattern is universal. Luna: Quick honest thing — a handful of listeners chip in monthly through Buy Me a Coffee dot com slash Fexingo, and that's literally what funds making episodes like this one. We don't run ads, we don't have sponsors, so listener support is what keeps the show going. If these conversations have moved your work forward in some small way, that's the place. Lucas: Yeah, it's a small group, but it makes a big difference. And it's why we can dig into cases like this without worrying about pleasing an advertiser. Luna: Exactly. So back to the utility — one more detail I found interesting. After they cut the approval time, the number of solar applications actually increased by 40 percent in the next quarter. Word spread that the process was fast, and more homeowners decided to install. Lucas: That's the virtuous cycle. Faster approval drives more demand, which increases volume, which puts pressure on the process again. But because they designed the tiered system to scale — the automated check handles more volume without adding staff — they were able to absorb the increase without the cycle time creeping back up. Luna: So the improvement was self-reinforcing. Lucas: Right. And that's the kind of operational change that pays for itself many times over, not just in customer satisfaction but in actual revenue from interconnection fees, and in the utility's own renewable energy goals. They're hitting their state-mandated solar targets faster because the pipeline is moving. Luna: I think the biggest takeaway for me is that they didn't need a big budget or new technology. They just needed to look at their own data and ask a hard question about why something took 83 days. Lucas: Exactly. The data was already there. They just hadn't looked at it as a process flow. Once they did, the fix was almost obvious.
