What this figure does and does not include

Transcription notes recorded when this tariff was encoded, including anything deliberately left out.

• One PDF holds three sellable options - 4-9 PM, 5-8 PM and PRIME - each with its own rate table. They are encoded as separate tariffs because a customer picks exactly one.
• The rate tables and the time-period table are on sheets filed three weeks apart: rates under Advice 5829-E effective Jun 1, periods under Advice 5837-E effective Jun 25. Both are current.
• Delivery Total + Generation, verified against the component columns: 0.02481 + 0.28981 + 0.00829 + 0.00003 + 0.00171 + 0.00591 + 0.00100 = 0.33156, the stated peak Delivery Total.
• Baseline Credit $0.10099/kWh applies to baseline usage regardless of TOU period - the same mechanism as PG&E E-TOU-C. Encoded by subtracting it from the tier-1 rate in every period, with tier_scope='prorata'.
• Base Services Charge $0.794/meter/day, encoded monthly as $24.1508.
• EXCLUDED and additional: Fixed Recovery Charge $0.00619/kWh and MCAM $0.00223/kWh, as on Schedule D.
• CPP variants are not modelled. Critical Peak Pricing charges $0.80/kWh during events called on the day, so it cannot be priced without an event feed.
• HOLIDAY LIMITATION: the engine's hour calendar has no holiday support, so SCE's eight holidays are billed as ordinary weekdays. Measured impact on this tariff is small because winter 4-9pm is mid-peak on weekdays and weekends alike - the schedules only differ in summer. In 2026 only Labor Day falls on a summer weekday, so the error is 5 hours a year at the on-peak/mid-peak difference: about $0.30 to $1.80 depending on usage.
