Common Questions About Your LADWP Bill

1. How Do I Read My LADWP Bill Once My Solar Panels Start Producing Power?

With the help of a solar meter, LADWP will measure the difference between the number of kilowatt-hours (kWh) your solar system generates during the month and the amount of kWh you draw from the grid. This difference is called Net Energy Metering or NEM, which LADWP uses to calculate your NEM/solar bill.

If your panels happen to generate more energy than you need in a particular month, the excess kWh will go back to the grid, and you’ll be credited on your future electric bills.2 

Since solar energy only affects the electricity charges of your LADWP bill, some elements will stay the same, like your minimum use charge, taxes, and special programs and subsidies — including reliability improvements and low-income and lifeline discounts for customers who otherwise can’t afford to pay. Watch LADWP’s “Understanding Your Solar Bill” video.

2. What Residential Rate Options Does LADWP Offer?

As a residential customer, you have two different rate options to choose from: the Standard Residential Rate (R-1A) and the Time-of-Use Residential Rate (R-1B).3

Here’s a quick breakdown to understand the main differences between LADWP’s residential rates.

Standard Residential Rate (R-1A)

The R-1A is the standard rate for all LADWP residential customers, and it’s based on the location of your home, the season of the year, and the amount of electricity you use in each tier.  

A1. Location

  • Zone 1
  • Zone 2

A2. Season

  • High Season (June - September)
  • Low Season (October - May)

A3. Tier*

kWh Tier 1 Tier 2 Tier 3
Zone 1 First 350 kWh Next 700 kWh Above 1,050 kWh
Zone 2 First 500 kWh Next 1,000 kWh Above 1,500 kWh

*The amounts of kWh in each tier are based on a 30-day billing cycle.

Time-of-Use Residential Rate (R-1B)

The R-1B Time-of-Use (TOU) rate is based on the time of day and the day of the week you use electricity, and it has three time periods: High Peak, Low Peak, and Base.4

Time Period Days of the Week
High Peak

20 Hours Per Week
Monday to Friday

1:00 p.m. - 4:59 p.m.
Low Peak

30 Hours Per Week
Monday to Friday

10:00 a.m. - 12:59 p.m.

5:00 p.m. - 7:59 p.m.

118 Hours Per Week
Monday to Friday

8:00 p.m. - 9:59 a.m.

If you are able to control your electricity habits, LADWP’s TOU rate plan is a great option to help reduce your home energy costs.

For example, by shifting the use of your power-hungry appliances like your dishwasher or washing machine to base or low-peak periods (early mornings or at nights), you will pay less for electricity with LADWP’s Time-of-Use Residential Rate (R-1B) than with their Standard Residential Rate (R-1A). Check if you’re a good candidate for LADWP’s R-1B TOU rate.

See the below TOU chart for further explanation on high-peak rates.

3. Am I Eligible for LAWPD’s TOU Rate If I Have Rooftop Solar?

Yes, if you have solar panels and a solar battery storage system at home — and if you’re a good candidate for LAWPD’s R-1B TOU rate — you can enjoy the financial benefits of solar and storage under a Time-of-Use (TOU) rate schedule. However, since TOU rates change throughout the day, if you happen to accrue credits, their value will be variable.

For example, one kWh of solar electricity that your system exports back to the grid at 9:00 a.m. (base period) will be worth less than one kWh exported back to the grid at 2:00 p.m. (high-peak period).
