A Glance at Residential Time of Use Rate Plans

 

 

On the Time-of-Use (TOU) rate plans, the price of electricity changes by time of day. These rates are best for customers who can be more flexible about when they are using the most energy in a day.

 

There are many reasons why a TOU rate may work better for you:

1.       A time-of-use rate provides you with more control over your monthly electricity bill-you decide the price you pay for electricity based on “when” and “how much” you use.

2.       Take advantage of lower rates on weekends, holiday and evening hours.

3.       If you can reduce your electricity usage during on-peak hours, you’ll be able to take advantage of lower rates during other times of the day/year.

 

California Rate Changes

On July 3, 2015, the California Public Utilities Commission (CPUC) approved the Decision on residential rate reform for Pacific Gas and Electric Company (PG&E), Southern California Edison Company (SCE) and San Diego Gas & Electric Company (SDG&E) and transition to time-of-use rates. As a result, the way utilities bill for electricity is changing throughout California.

 

Here are some of the important takeaways:

1.       Migration from 4 rate tiers to 2 tiers, plus a “super user electric” (SUE) surcharge rate.

2.       Default time of use rates starting in 2019.

3.       No new fixed charges, $10/$5 minimum bill adopted instead.

 

EV Rate Plans

As mainstream auto makers add electric vehicles to their product lines, electric utilities are making it easier for customers to own plug-in electric vehicles and to integrate them into the electric system by offering a special rate for charging electric vehicles.

There are two kinds of qualifying electric vehicles (EV):

1.       A pure electric vehicle or a plug-in hybrid electric vehicle. Electric Vehicles (EVs) use electricity as their only power source and are powered via a rechargeable battery. EV batteries are charged by plugging the vehicle into an electric power source. These vehicles are often referred to as Battery Electric Vehicles (BEVs.)

2.       Plug-in Hybrid Electric Vehicles (PHEVs) which use both conventional fuel and electricity to power the vehicle. PHEVs can be plugged into an electric power source to charge the battery, and typically have a longer range than an EV.

 

 

Here are the main TOU rates available in California and Nevada:

 

Electric Utilities

Rate Plans

Customers Who May Benefit

PG&E

ETOU-A

Customers who don't use much energy (tier 1 on E1) and can be flexible about when you use it. If you can reduce your usage from 3 p.m. to 8 p.m. on weekdays this rate plan may be best for you.

ETOU-B

Customers who use more energy (tier 2 or 3 on E1) and can be flexible about when you use it. If you can reduce your usage from 4-9 p.m. on weekdays, this rate plan would be beneficial.

EV-A

Higher energy consumers (tiers 2 and 3) or lower energy consumers (tier 1) who will drive often. If you can reduce your usage from 7 a.m. to 11 p.m. on weekdays, and 3 p.m. to 7 p.m. on weekends and holidays, this rate plan may be best for you. Single meter for your home and EV charging.

EV-B

Customers who want to track their EV charging separate from their home energy consumption with a dedicated meter. If you can reduce your usage from 7 a.m. to 11 p.m. on weekdays, and 3 p.m. to 7 p.m. on weekends and holidays, this rate plan may be best for you.Dual meters: one for your household and one for electric vehicle charging.

SCE

Customers whose average usage is less than 700 kWh a month.TOU-D Option A (TOU-D-A) has three different time periods and associated pricing.

TOU-D-B

Customers whose average usage is more than 700 kWh a month. TOU-D Option B (TOU-D-B) has three different time periods and associated pricing.

TOU-D-T

This rate plan is popular with high-usage and self-generation customers. The Off-Peak Savings Plan (TOU-D-T) has two different time periods and four different pricing levels.

TOU-EV-1

Customers who charge an electric vehicle at home. This rate plan requires a separate dedicated meter.

SDG&E

DR-SES

TOU-DR

A time-of-use option for residential customers.

TOU-DR-P

A time-of-use option for residential customers who also choose to manage their electric costs by reducing their use when an event is called.

EV-TOU

An electric vehicle (EV) TOU rate plan that requires a separate meter for your EV. The EV meter tracks your vehicle’s electricity use separately from the rest of your home. A licensed electrician of your choice is required to install this second meter at your expense.  Solar customers are unable to use solar energy for this meter.

EV-TOU-2

An electric vehicle (EV) TOU rate plan that uses your existing household smart meter to track home and EV electricity use.  Since all of your electricity is measured by one meter, the time-of-use price applies to your overall use and the price does not change as you use more electricity.

NV Energy

Northern Nevada

TOU Rate Plan

Customers who are willing to use less electricity during periods when the total demand of energy is highest (the peak), will save money by shifting their usage to times with lower rates. Some could even save 15% off their annual electricity bill if they decide to use less electricity during these peak periods.

Southern Nevada

TOU Rate Plan Option A

Customers who are willing to reduce consumption during periods when the total demand for electricity is highest, (the peak) will save money.
