Review of Southern California Edison's New Post Solar Electricity Rates and its Impact on Savings

On March 1, 2019 Southern California Edison (SCE) will close its current default post-solar tariff (TOU-D-A-NEM2) and replace it with a new default post-solar tariff (TOU-D-4-9PM-NEM2). This tariff change will dramatically impact solar savings in SCE as the Time of Use (TOU) On-Peak hours move from 2-8 PM under TOU-D-A-NEM2 to 4-9 PM under TOU-D-4-9PM-NEM2. More importantly TOU-D-4-9PM-NEM2 introduces a Super Off-Peak period in the Winter from 8 AM to 4 PM, when the majority of solar production occurs.

Savings Analysis API Support for Non-bypassable Charges

Genability has just upgraded both our Savings Analysis API and our Calculate API to better support Non-Bypassable Charges (NBCs). What are NBCs you ask? Well that’s how the California utilities refer to the customer’s annual NBCs that cannot be offset by Net Energy Metering (NEM) Credits under NEM 2.0. These NBCs behave as a second minimum charge calculation that’s performed during the customer’s annual true-up.

If you are selling solar, storage and/or energy efficiency in California, you want to be sure to calculate savings using these new tariffs.

Solar Incentives in Illinois, Net Metering Ends for Duke Energy South Carolina

The roller coaster for solar in the U.S. (call it a Solar Coaster?) keeps rolling this summer.  The state of Illinois has finalized the credit values for its Adjustable Block Program, which provides solar owners with an upfront payment for 15 years of estimated solar production.  Meanwhile, in South Carolina the state legislature failed to increase the net metering cap and Duke Energy has met its 2% limit. Starting on August 1, 2018 full net metering closes for Duke Energy SC customers and will be replaced by the Purchased Power Rider. First the good news for solar developers:

Hawaiian Smart Export and Customer Grid Supply Solar Programs

Starting on 2/20/2018, the three Hawaiian investor-owned utilities will offer two new programs for customers with solar: Customer Grid Supply Plus and Smart Export. Both programs offer export credits for power provided to the grid, an option that has not been available in Hawaii since the Customer Grid Supply programs closed in 2017. Genability has just made these two programs available for Hawaiian Electric Co (HECO), Hawaiian Electric Light Co (HELCO) and Maui Electric Co (MECO) for use in your solar proposals.

California Residential Electricity Rate Changes - January 2020

By

| Reading time 3 minutes

Southern California Edison (SCE), Pacific Gas & Electric (PG&E) and San Diego Gas & Electric (SDG&E) all released new tariff rates on January 1, 2020 improving the economics of residential solar for all three utilities.

SCE - 20% Increase in Avoided Cost of Power (ACP)

For residential solar developers the highlight was the much anticipated redesign of the default residential post-solar tariff TOU-D-4-9PM. The result was a result was a 19%-23% increase in the Avoided Cost of Power (ACP), depending on the region within SCE’s service territory.

  Old ACP New ACP % Change
Baseline Region 5 13.1¢/kWh 16.1¢/kWh +23%
Baseline Region 6 15.4¢/kWh 18.5¢/kWh +20%
Baseline Region 8 15.5¢/kWh 18.5¢/kWh +19%
Baseline Region 9 14.7¢/kWh 17.7¢/kWh +20%
Baseline Region 10 14.0¢/kWh 17.2¢/kWh +23%
Baseline Region 13 13.7¢/kWh 16.7¢/kWh +22%
Baseline Region 14 14.5¢/kWh 17.5¢/kWh +21%
Baseline Region 15 13.9¢/kWh 17.1¢/kWh +23%
Baseline Region 16 14.8¢/kWh 17.8¢/kWh +20%

While both delivery and generation costs increased with the January 2020 tariff version, it was the rebalancing of time of use generation prices that drove the increase in ACP. In the chart below you see that the price difference between the time of use periods has narrowed and in particular the Winter Super Off-Peak price has increased 31%. The increase in the Summer Off-Peak (9 PM - 4 PM) and Winter Super Off Peak (8 AM - 4 PM) is particularly helpful for solar developers as it coincides with peak solar production.

  Old Rate New Rate % Change
Summer On- Peak
(Weekdays 4 PM -9 PM)
41.1¢/kWh 37.2¢/kWh -9%
Summer Mid-Peak
(Weekends 4 PM -9 PM)
26.6¢/kWh 30.2¢/kWh +14%
Summer Off-Peak
(All days 9 PM - 4 PM)
22.2¢/kWh 23.3¢/kWh +5%
Winter On-Peak
(All days 4 PM - 9 PM)
29.1¢/kWh 32.2¢/kWh +11%
Winter Off-Peak
(All days 9 PM- 8 AM)
27.7¢/kWh 24.4¢/kWh -12%
Winter Super Off-Peak
(All days 8 AM - 4 PM)
16.9¢/kWh 22.2¢/kWh +31%

PG&E - Closes E-TOU-A, E-TOU-C New Default Post-solar Tariff

On January 1, 2020, Pacific Gas & Electric closed E-TOU-A to new subscribers. With the closing of E-TOU-A in 2020, the new default post-solar tariff will be E-TOU-C. The primary difference between E-TOU-A and E-TOU-C lay in the time of use definitions. While both tariffs have a 4 PM to 9 PM peak period, E-TOU-C extends the on-peak period into weekends and holidays, whereas E-TOU-A limits the on-peak period to weekdays.

In addition there are small differences in the time of use rates (see table below).

E-TOU-A E-TOU-C
Summer On-Peak 42.3¢/kWh 39.7¢/kWh
Summer Off-Peak 34.7¢/kWh 33.4¢/kWh
Winter On-Peak 30.5¢/kWh 31.0¢/kWh
Winter Off-Peak 29.1¢/kWh 29.3¢/kWh

The overall impact of the switch from E-TOU-A to E-TOU-C on the Avoided Cost of Power (ACP) for PG&E is negligible. ACP increased in 7 Baseline Regions between 0.1 and 0.3¢ while ACP remained identical for 4 Baseline Regions.

Genability has not yet set the closed date on E-TOU-A in order to allow our customers to continue to quote projects that received interconnection approval before January 1, 2020. We will be adding the closed date on 4/1/2020. In the meantime we have added “Closed” to the tariff name and made E-TOU-C the most popular solar eligible residential tariff to direct solar developers to the best post-solar tariff.

SDG&E - Nears End of Time of Use Transition

On March 1, 2019 San Diego Gas & Electric began its year-long process to transition its customer base from their previous default tariff DR to their new default tariff with time of use pricing TOU-DR1. Genability has updated its customer counts to reflect this transition and you will now see TOU-DR1 as the default pre-solar and post-solar tariff for SDG&E.

Switching the pre-solar tariff from DR to TOU-DR1 increases the Avoided Cost of Power for SDG&E by between 0.6 and 0.7¢/kWh due to the higher, pre-solar costs.
