Net Energy Metering (NEM)

Net Energy Metering (NEM) is a program offered by SDG&E to customers installing photovoltaic, solar electric or wind generating systems.  Through interconnection with SDG&E's power grid, SDG&E is able to measure the "net" difference between the energy generated by the customer and the energy purchased from SDG&E.  The NEM program is a 12-month program that automatically renews at the end of each 12-month cycle.  Under this program, residential customers need only pay the electric portion of their utility bill once every twelve months.

Incentive Programs

Cash rebates may be available for eligible solar electric, photovoltaic or wind systems.  Here are two incentive programs available to SDG&E customers.

Electric Rate Schedules

If your system is 1000 kW or less the Net Energy Metering (NEM) tariff may apply.  For additional rates and tariffs applicable to self-generation projects go to Rates and Tariffs.

DR-SES (Solar Energy System) Tariffs

Application for Interconnection

Each customer installing a photovoltaic, solar electric and/or wind generating system is required to submit a set of documents for interconnection. Please note that a different application is used for systems greater than 30 kW. Choose the application suitable for the size of the system being proposed.

Solar Fact Sheet

Am I eligible for Net Metering?

Any SDG&E residential or commercial electricity customer who generates at least some of their electricity is eligible for net metering.  The basic eligibility requirements are (1) your electricity generating system must be powered by solar or wind energy or a combination of the two, and (2) Your system must not exceed 1 Megawatt of peak power output.

What are the Benefits of Net Metering?

You receive full retail rate for excess power

Net metering allows you to get full retail value for the electricity you produce.  It does this by permitting you to put any excess electricity you generate back into the electric grid and retrieve it later, free of charge.  Your excess electricity now offsets electricity you would otherwise have to buy at full retail prices.  This makes owning your own generating system more cost effective.   But, remember, you can only get the full retail value for electricity equal to 100% of your total annual consumption.

You can “store” power on the grid

Because you get credit for your excess power generation, there is no immediate need for batteries to store energy for use in the evening when you system is not generating power.

How Does Net Metering “Store” My Electricity?

Net Metering allows you to use SDG&E’s electric grid as a big battery.  There could be times when your PV system will be producing more electricity than your home or business demands at that moment.  Under Net Metering, during these times, power is fed back into SDG&E’s grid to be used by others and you can take this same amount of electricity back out of the electric grid at a later time.  Net Metering permits you to “bank” your excess electricity and then withdraw it from the grid free for you use at a later time.

Can I Use My Current Electric Meter for Net Metering?

Generally, yes.  Most residential and small commercial customers have simple meters that are already capable of turning in both directions.

For larger commercial systems, we may want two meters for net metering. A special billing meter to measure all the electricity flowing into your business from the grid and the excess you are putting into the electric grid, and, a net generator output meter to measure the electricity generated by your system.

How Do I Sign Up for Net Metering?

When you decide to install a photovoltaic or wind generating system, contact SDG&E to request Net Metering.  The sooner you contact us, the sooner you can get your system approved for connecting to the electric grid.  For information on interconnection go to Application for Interconnection.

Will SDG&E Pay Me Full Retail Rates for My Excess Electricity Generation above 100% of my annual Consumption?

SDG&E is not required to purchase/credit you for any excess annual generation (more than 100% of your annual consumption). 

Are there any special inspections or fees to get my system hooked up the electric grid?

There are no special fees required but before you connect to the grid SDG&E will perform an inspection to make sure the system is connected safely.

Will the electricity I might still need to buy from SDG&E cost me more than before I became a Net Metered customer?

No, there are no extra charges for being a Net Meter customer and no charges are imposed on the electricity you generate.
