Last Updated 2/28/2019
Genability has begun entering and reviewing the new Southern California Edison (SCE) tariffs for the 3/1 update. We will be entering rates and testing them thoroughly before making them available via our API. In the meantime, here are a few highlights from the newly-released rates.
New Baseline Allocations
Starting on 3/1, SCE will be changing the Baseline Allocation for all Residential tariffs. In general the baseline allocations have increased for customers with gas heat and decreased slightly for customers with electric heat. Here are the old and new values for customers with gas heat:
| Territory | Season | Old | New |
| Zone 5 | Summer | 13.7 | 17.2 |
| Zone 6 | Summer | 9.4 | 11.4 |
| Zone 8 | Summer | 10.4 | 12.6 |
| Zone 9 | Summer | 13.8 | 16.5 |
| Zone 10 | Summer | 16.2 | 18.9 |
| Zone 13 | Summer | 18.8 | 22.0 |
| Zone 14 | Summer | 16.1 | 18.7 |
| Zone 15 | Summer | 39.9 | 46.4 |
| Zone 16 | Summer | 12.1 | 14.4 |
| Zone 5 | Winter | 15.2 | 18.7 |
| Zone 6 | Winter | 9.6 | 11.3 |
| Zone 8 | Winter | 9.1 | 10.6 |
| Zone 9 | Winter | 10.6 | 12.3 |
| Zone 10 | Winter | 10.8 | 12.5 |
| Zone 13 | Winter | 10.9 | 12.6 |
| Zone 14 | Winter | 10.5 | 12.0 |
| Zone 15 | Winter | 8.2 | 9.9 |
| Zone 16 | Winter | 10.8 | 12.6 |
New Distribution Rates for TOU-D-4-9 and TOU-D-5-8
With the new rates, SCE has made two changes to the Distribution Rates.
- Distribution Rates Nearly Double – We see the Distribution rate jumping from 8.5¢/kWh (all hours) to 15.8¢/kWh (Summer On & Mid-Peak, Winter Mid-Peak). This makes more of the customer’s costs available for delivery minimums when most kWh are offset by solar.
- Distribution Rate to Vary by Time of Use (TOU) – Under the new tariffs, the Distribution rate varies according to the time of use period. The distribution rate varies from 15.8¢/kWh (Summer On & Mid-Peak, Winter Mid-Peak) to 11.1¢/kWh (Winter Super Off-Peak).
New TOU Periods for Commercial Tariffs
As expected, the new SCE tariffs change the Time of Use Periods for all Commercial tariffs with Time of Use pricing. We cover these changes in depth in our Proposed Tariff post.
No Change in TOU-RTP Categories
It’s long been expected that SCE was going to simplify the day-type categories from 5 to 3 categories, but it is not included in the new tariff versions. Per the newest documents, SCE has maintained the 5 Summer Day Type categories.
More Follow Up
Once the new SCE rates have been made available via our API, we will update our analysis of APIs with the final rates released by SCE. In the meantime we ask for your patience as we enter and verify the new rates before making them available for your calculations. Thank you.
