Net Energy Metering Equipment & Programs

Which System & Program Is Right for You?

Once you decide to install your own generating facility, you’ll need to select a system and apply for the right NEM program. We’ve provided options so you can make informed choices for your home or business. To start, you’ll need to choose which qualifying renewable energy system to install:

View More View Less
  • Solar Photovoltaic
  • Wind
  • Fuel Cell1
  • Biogas
  • Biomass
  • Digester Gas
  • Geothermal
  • Hydroelectric up to 30 MW2
  • Landfill Gas
  • Municipal Solid Waste Conversion3
  • Ocean Thermal
  • Ocean Wave
  • Solar Thermal
  • Tidal Current

1 To qualify for standard NEM, a fuel cell system must be powered solely with renewable fuel.
2 A “small hydroelectric” generating facility is not an eligible renewable generating facility if it will cause an adverse impact on in stream beneficial uses or cause a change in the volume or timing of stream flow.
3 Qualifying “solid waste conversion” is defined pursuant to Public Resources Code Section 25741(b)(3).

Selecting Your Program

Standard NEM will apply to the majority of residential customers. For non-residential customers, there are a number of options and considerations depending on different customer types. For example: Multifamily property owners can enroll in a program that distributes credits to individual tenants, or aggregate all onto one bill. If you’re not sure which option is right for you, your Account Representative can help you identify which program is the best fit for your facility.

Renewable Generation paired with Storage

The NEM paired storage program is designed for customers with an eligible generator that has an integrated or directly connected paired-energy storage device, like a battery, behind the same revenue meter.

Multiple Meters

The NEM aggregation program is available for customers with multiple meters on a property (or contiguous properties). You may be eligible to reduce the electric load of the aggregated meters using one generating system.

Once you are on NEM Aggregation, check out the Welcome Guide which provides details of how your bill will be calculated for the aggregated service accounts. 

Multi-Tenant Properties

Virtual Net Metering (VNM) allows energy produced by a renewable generating system to be credited to utility accounts for properties with both multiple meters and multiple tenants.

Alternatively, Virtual Net Metering (VNM) for the Multifamily Affordable Solar Housing (MASH) program allows participants to apply credits from a single renewable generating system to multiple accounts at an eligible low-income building.

Fuel Cell NEM

This program applies to customers with an eligible fuel cell system that complies with CPUC standards of emissions and greenhouse-gas reduction, and requires a Time-of-Use (TOU) rate.

Multiple Tariff

NEM Multiple Tariff (NEM-MT/NEM-MT-ST) allows customers to install a Generating Facility (GF) consisting of a) one or more NEM Eligible Generators served under Schedule NEM and one or more NEM Eligible Generators served under Schedules NEM-ST, BG-NEM and/or FC-NEM, or b) consisting of one or more NEM Eligible Generators served under Schedule NEM and one or more Non-NEM Eligible Generators.

For NEM-MT/NEM-MT-ST interconnection requests seeking to interconnect a non-NEM Eligible Generator behind the same SCE revenue meter / Point of Common Coupling as an existing NEM Eligible Generator, Application Form 14-732 online should be used in lieu of Application Form 14-957 online.

Military Sites and CDCR

Senate Bill 83 created a special NEM program for properties on Armed Forces bases or facilities with renewable generating systems that meet the program guidelines.

On February 10, 2016, SCE’s Advice Letter 3282-E “Tariff Modifications Necessary to Implement the NEM Provisions of Senate Bill (SB) 83 for the U.S. Armed Forces” was approved by the California Public Utilities Commission with an effective date of November 1, 2015.

SB 83 expanded the definition of an NEM Eligible Customer-Generator to include an establishment under the jurisdiction of the United States Army, Navy, Air Force, Marine Corps or Coast Guard (hereinafter referred to as an “Armed Forces base or facility”) when using a renewable electrical generation facility (REGF), or a combination of those facilities, with a total capacity that does not exceed the lesser of (a) 12 megawatts (MW) or (b) 1 MW greater than the minimum load of the Armed Forces base or facility over the prior 36 months.

The statute includes the following additional provisions, which are applicable only to NEM Eligible Customer-Generators as newly defined under Section 2827(b)(4)(C):

  • The REGF must be located on premises owned, leased or rented by the Armed Forces base or facility, be interconnected and operate in parallel with the electrical grid, and be intended primarily to offset part or all of the Armed Forces base or facility’s own electrical requirements.
  • Unless prohibited by federal law, a REGF shall not be eligible for NEM for privatized military housing if the REGF was procured using a sole source process. A REGF procured using best value criteria, if otherwise eligible, may be used for NEM for privatized military housing.
  • The Armed Forces base or facility shall not receive compensation for exported generation.
  • Notwithstanding paragraph (2) of subdivision (e) of Section 2827.2 an electrical corporation shall be afforded a prudent but necessary time, as determined by the executive director of the California Public Utilities Commission (CPUC) but not less than 60 working days, to study the impacts of a request for interconnection of an REGF with a capacity greater than 1 MW.
  • If the study reveals the need for upgrades to the transmission or distribution system arising solely from the interconnection, the electrical corporation shall be afforded the time necessary to complete those upgrades before the interconnection and the costs of those upgrade projects shall be borne by the NEM Eligible Customer-Generator.
  • Upgrade projects shall comply with applicable state and federal requirements, including requirements of the Federal Energy Regulatory Commission (FERC). For any REGF that interconnects directly to the transmission grid or that requires transmission upgrades, the Armed Forces base or facility shall comply with all FERC interconnection procedures and requirements.
  • An electrical corporation shall make a tariff, approved by the Commission, available to implement these new NEM provisions for an Armed Forces base or facility by November 1, 2015.
