2026 ONYX LN2 Gas Delivery Monitoring Report

Phase 1: Winter/Spring Audit (Completed)

Duration: December 31, 2025 – April 3, 2026

Metric	Ground Truth (Totalizer)	Logger Integration
Start (12/31/25)	0 SCF	0 SCF
Mid-Point (01/12/26)	105,935 SCF	105,274 SCF
End (04/03/26)	923,190 SCF	931,292 SCF
Variance	-0.87% (Logger High)

Audit Notes: The 0.87% variance is well within the ±1% factory specification. A slight "over-counting" drift was observed as ambient temperatures rose from 28°F in January to 62°F in March. Data resolution was found to be 4.5 minutes due to an interval setting error in Phase 1.

Phase 1 Usage Analysis

Usage Trends: Base load remains steady near 386 SCFH during off-hours and weekends. Weekday usage reliably ramps up starting at 6:00 AM, peaking around 1:00 PM (~481 SCFH average), and tapers off near 7:00 PM.

Peak Usage Recorded: 1062.50 SCFH on Feb 27, 2026 at 11:16 AM.
Weekday Average: 430.76 SCFH
Weekend Average: 386.53 SCFH

Phase 2 Gas Consumption Over Time

Phase 2 Usage Analysis

Usage Trends: Overnight base load averages ~347 SCFH. Weekday demand climbs from 8:00 AM, peaking around 1:00 PM (~418 SCFH average), and tapers off by 7:00 PM. Summer usage is noticeably lower than Phase 1 winter/spring values — weekday average is down 10.5% and peak flow is 23.5% lower, consistent with lower cryogenic demand in warmer months.

Peak Usage Recorded: 812.50 SCFH on June 24, 2026 at 2:10 PM
Weekday Average: 385.47 SCFH
Weekend Average: 340.41 SCFH
Monthly Totals: April 250,687 SCF | May 279,446 SCF | June 252,938 SCF
Peak Ramp: Usage peaks at 1:00 PM (417.86 SCFH avg) vs. 1:00 PM in Phase 1
