Overview - NEM Rates

To make a smart decision about which rate you should be on, we encourage you to perform a  simple self-analysis of your regular energy usage.

You can do this by reading your electric meter at 11 a.m., then again at 6 p.m. and subtract the first reading from the second reading. The end result will show a positive number (how much energy you using) or a negative number (the excess energy sent back to the grid).

If your electricity use during on-peak hours (11 am – 6 pm weekdays) is less than the amount your solar system is producing, the NEM billing rate could help lower your annual electricity costs.

Weighing the Financial Benefits

The price of energy is much higher during on-peak hours, especially during the summer months, when a SES typically produces electricity at maximum output. This means that every excess kilowatt-hour your system generates is credited to your account at the higher rate during the on-peak period. 

If you reduce your energy usage during the on-peak period, your solar system sends the energy you produced to SDG&E’s system and credits you. The higher credits you receive can offset the cost of electricity during times when your solar system is not meeting your full energy needs and you’re using electricity from SDG&E.

Keep this in mind: If you use more on-peak electricity than your SES produces, you’ll be charged the higher rate for the energy you use. It’s possible your bill could end up being higher than it would have been under the standard residential rate.

Electric Rate Tiers Breakdown By Summer/Winter

The time periods, seasons and costs below can help you to do your analysis to determine if the NEM billing rate is right for you.

The Standard Residential Electric Rates reflect Total UDC rates under Schedule DR, SDG&E's primary schedule for residential electric service, and the applicable rates under Schedules EECC and DWR-BC.

The chart reflects rates with an effective date of January 1, 2013 (AL 2443-E).

* Electricity use that falls within the monthly baseline allowance of kWh shown on your SDG&E bill is billed at the baseline rate per kWh, which is the lowest rate.

Kilowatt-Hour Costs

Schedule DR-SES Kilowatt-hour costs

Time-of-Use Meter Charge

0.0¢ per month

Summer on-peak

27.9¢ per kWh

Summer semi-peak 

19.0¢ per kWh

Summer off-peak

17.3¢ per kWh

Winter semi-peak

18.4¢ per kWh

Winter off-peak 

17.5¢ per kWh

Keep this in mind: If you use more on-peak electricity than your SES produces, you’ll be charged the higher rate for the energy you use. It’s possible your bill could end up being higher than it would have been under the standard residential rate.

Time of Use Periods and Seasonal Rate Changes

With a time-of-use rate like DR-SES, the price of electricity varies according to on-peak, semi-peak and off-peak use time periods as seen in the following table.

Time Periods

Summer on-peak

11am - 6pm, Mon - Fri,
except holidays

Summer semi-peak (except holidays)

6am - 11am and 6pm - 10pm,
Mon - Fri

Summer off-peak

10pm - 6am, Mon - Fri
and all hours on weekends and holidays

Winter semi-peak 

6am - 6pm, Mon - Fri,
except holidays

Winter off-peak

6pm - 6am, Mon - Fri
and all hours on weekends and holidays

Winter and Summer Seasons

Depending on your energy usage throughout the day and the amount of electricity produced by your solar energy system, you may be able to reduce your annual energy costs.

Seasons
