Power systems engineer working in utility infrastructure with a focus on substations, protection systems, and grid reliability projects. Most of my work involves supporting upgrades to existing systems, coordinating with field teams, and troubleshooting issues that come up during commissioning and outage work.

On a few substation and URD upgrades lately, the real bottleneck hasn’t been cable rating or relay settings. It’s duct bank and soil behavior. After the first hot summer, we logged cable temps higher than our model, and the common thread was dry-out around the encasement or a field swap to a “standard” backfill that met strength/compaction but had poor thermal performance.Civil specs I see often center on compressive strength, slump, and density. Fair, but those choices can push us toward CLSM o...
In substation upgrades, the critical path is rarely the steel and wire. It is the outage window and the parts you cannot rush: relays, CTs, breakers, and the occasional transformer. Ops gives you two weekends in October, procurement says 40 weeks, and the program wants the feeder back before summer. I see a lot of schedules that ignore that math.What has helped on my projects: lock outage windows with operations early and drive the plan to those dates. Place long lead POs off a functional spec a...
I see substation upgrade schedules slip less from engineering effort and more from decision timing. The outage window owns the critical path. If SCADA point lists, protection philosophy, or relay comms modes are still open 4-6 weeks out, you are gambling with crew time and switching plans.What helped on recent jobs was a simple set of gates: a design freeze at 60%, a settings and point list freeze 12 weeks before outage, and an energization package review 4 weeks out. Each gate has owners on ope...
Recent substation upgrade in Pittsburgh: replaced a 25/33 MVA transformer, added caps, refreshed relays. The arc flash study jumped at the 480 V MCCs because source Xd fell and feeders are short. ETAP said we could knock it down with faster clearing, but that broke coordination with downstream fuses, especially with two 5 MW PV sites backfeeding.Commissioning added a twist. The old bushing CTs on the transformer saturate sooner than nameplate suggests, so 50/51s were slower in reality. We ended...
We piloted a remote racking robot and a quadruped inspector at two stations. The racking unit has been a clear win: less arc flash exposure, smoother lockout steps, and quicker breaker turns during outages. It needs clean floor rails and disciplined procedures, but one trained tech can do what used to take three.The quadruped was mixed. It handled thermal and acoustic checks, but struggled with gravel, cable trenches, and swing gates. GPS is useless, LTE is spotty near steel, and battery swaps a...
As we push more automation into substations and feeders, the grid reminds you it isn't a clean lab. We rolled out a FLISR scheme using SEL relays, an RTAC, GOOSE, and PTP. First big storm, comm latency and stale DER telemetry had two reclosers hunting topology changes. We fixed it with hold-off timers, state voting, QoS on the radio links, and data-age checks before any trip/close.On the robotics side, ground robots for substation inspections cut crew exposure and kept patrols going in ice...
