Substation Engineering
Long-cycle programs where regulation, capital, and grid reliability define the pace.
This interactive experience is the shipped product itself — the same application code customers run in production, mounted read-only in your browser over a real sample journey. Not a video, not a mockup: because the demo and the product are one codebase, it can never drift from the real thing.

-
Pre-Deployment Readiness
Confirm construction windows, outage coordination, permits, equipment lead times, site access, and named owners before execution begins.
Pre-Deployment Questions
Environment and site access
- List the site name/ID(s) this deployment will touch and whether each is a single-bay or multi-bay substation (one per line). (We use this to split site-level tasks and crews.)
- Is site access cleared for construction (security badge required, escorted access, gate hours)? (select the best match — this determines crew mobilization and daily windows)
- Staging and laydown area availability for equipment deliveries at each site (so we can plan truck routing and crane operations).
Equipment, materials and permits
- Status of long‑lead equipment (transformer, major switchgear, primary protection platforms): are lead times confirmed against the current schedule?
- Permit status per site for construction, electrical, and AHJ approvals (so we can lock work start dates).
- If any permits or equipment confirmations are pending, what is the expected approval or confirmation month for each site? (enter month/year per site)
Timing and outage coordination
- Planned outage window(s) per site (start date — end date or 'TBD'). (We must align crew schedules and utility approvals to these windows.)
- Who is responsible for obtaining utility/system operator outage approvals?
- Are there blackout periods or operational constraints (seasonal, business-critical hours, or other no‑work windows) that would prohibit construction, energization, or testing?
People and ownership
