Teniendo en cuenta la energía renovable para su hogar o empresa

What is Net Energy Metering?

Neto de medición de energía, o NEM, implica una conexión bidireccional entre la red eléctrica de SDG & E y su sistema de generación de electricidad.

Si usted tiene un sistema de generación de electricidad que utiliza una fuente de combustible renovable en su hogar o negocio, tales como la solar, y su sistema produce más energía que utiliza, puede ganar créditos en la factura por exceso de poder que fluye de su sistema a la red eléctrica de SDG & E . 

At times when the renewable fuel source is unavailable or limited, like when the sun isn't shining or on cloudy days, and your system isn't producing enough electricity to meet your needs, you will likely need to use SDG&E as a source of back up power or rely on the credits that you may have generated at an earlier time.

This give and take is referred to as Net Energy Metering or NEM.

Any SDG&E residential or commercial customer who generates at least some of their electricity with a renewable energy source is eligible to participate in the NEM program.

There are two primary eligibility requirements for NEM:

  1. Your electricity generating system must be fueled by solar, wind, or a different renewable source that is eligible for NEM. Other renewable fuels include, but not limited to, biomass, geothermal, and small hydro.
  2. ​Your system must comply with the rules and regulations for interconnecting customer-owned generation to SDG&E's grid.

There is a state mandated cap on NEM and the rules for customers with systems connected before the NEM cap was met are slightly different than the rules for customers that connect afterwards.

On June 29, 2016, the NEM Cap was reached in SDG&E's service territory.

Customers with authorized interconnections established before this date are generally subject to the provisions of Schedule NEM. *

Customers with authorized interconnections established after this date are generally subject to the provisions of the NEM Successor Tariff or NEM-ST. ** 

Net metering allows you to get retail value for the electricity you produce by permitting you to put excess electricity you over-generate back into the electric grid and retrieve it later. Your excess electricity now offsets electricity you would otherwise have to buy. Since your solar energy system is connected to SDG&E's distribution system, you're helping to reduce the demand for electricity and supporting a cleaner energy future.
