The regulation — plain English
California At-Berth Regulation, § 93130.5
2023Tier 1 took effect for container vessels. 80% of visits must be connected to shore power within 2 hrs of mooring.
2025Tier expands to tankers and reefers calling on CA ports. Exhaust-capture systems no longer accepted as primary compliance.
2027Tier tightens to 90% for containers. Auxiliary engine run-time audits begin.
Penalty — $26,000 per vessel visit over the 2-hour mooring-to-plug window. Terminals share liability with operators.
You & Pier 400 — you're running at 96.8%, 16.8 pts above floor. Your avg plug-in time is 11 minutes.

gCO₂e/kWh · honest framing
The emissions picture — two ways to read it.
CAISO grid is fairly clean (~245 g/kWh). But the win isn't electricity-vs-electricity — it's displacing bunker fuel burning on the vessel. That's a 6.5× reduction at the quayside airshed.

What Longshore & Operations care about
✓ Crane power never drops. STS 1-6 run on a UPS-backed 480V bus · GX230 grid-forming absorbs the brownout.
✓ Reefers don't thaw. 484 plugs, 1.0 kW avg · would take a 10-minute outage for any setpoint drift to matter. We've had 0 reefer alarms tied to power YTD.
✓ Gate ops & TOS stay up. 280 kW terminal baseload is on the same grid-forming bus as the HVSC berths.
✓ Plug-out is reportable. Any vessel disconnect is a CARB event. Every grid disturbance this year: vessel stayed on shore power.
