Get a Read On Net Energy Metering

If you purchase electricity from SCE, install a renewable energy system to be eligible for our Net Energy Metering (NEM) rate option. With NEM, you can zero out your bills by receiving a credit for any surplus energy you generate beyond what you consume.

NEM Programs

To be eligible for NEM, your system must be sized to your historic electric use and cannot exceed 1,000 kilowatts. SCE offers several NEM programs:

Standard NEM Fuel Cell NEM Virtual Net Metering (VNM)

For SCE customers who install renewable energy system using:

  • 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

For SCE customers on a Time-of-Use (TOU) rate who:

  • Install a system using technology that the CPUC has determined will achieve reductions in emissions of greenhouse gases pursuant to subdivision (b) of PU Code § 2827.10, and
  • Meets the emission requirements for eligibility for funding set forth in subdivision (c) of PU Code Section 379.6, and
  • Commence operation on or before January 1, 2015.
Under Virtual Net Metering, the owner or operator of a multi-tenant property designates the percentage of the total metered output of the generator or generators, to be allocated to each tenant service account known as ‘Benefiting Accounts’.

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).

Option R Tariff

Option R Tariff

Overall capacity for the Option R Tariff is 150 megawatts (MW). As of October 12, 2013, the Option R cumulative 150 MW cap is fully subscribed and closed. This means that no new service accounts can go on Option R, and any service accounts currently on Option R cannot increase the generation system size above what was previously approved.   If the generation system size is increased, the account will be removed from Option R since it will no longer be eligible.

TOU-8 Special Solar Allowance

TOU-8 Special Solar Allowance

  • Established for TOU-8 Option A and is limited to customers who install solar generation and who would otherwise qualify for TOU-8 Option R.
  • A cap of 50 MW is set for the otherwise qualifying TOU-8 Option R customers to be served under TOU-8 Option A.
  • Option A has no time-related demand charges and has a full facilities-related demand charge.


We do not issue TOU-8 Option A tariff reservations prior to granting customers Permission to Operate (PTO). After customers receive PTO from SCE, they can apply for the TOU-8 Option A tariff by submitting a Rate Change request form.

  • Demand greater than 500 kW but not exceeding 4 MW
  • Account qualifies for TOU-8 rate
  • Account has 12-months of active history
  • For customers without 12 months of demand data, SCE will determine the annual peak demand once the customer has three months of demand data
  • On site eligible renewable generator installed with net capacities 15% or greater than the customer’s annual peak demand recorded over the previous 12 months
  • Generation system expansions/increases cannot exceed the cumulative 50 MW cap.  Account will be removed from Option A if the generation system increases above the previously approved generation system size after the 50 MW cap has been reached and closed.
  • No other non-renewable generator is on site
  • Permission to Operate (PTO) letter issued
  • Rate change requested.  Eligible applicants will be given 15 calendar days from the date SCE approves their eligibility to sign up for the Option A tariff by submitting a Rate Change Request form
