General Net Energy Metering Questions

NEM Program

How does the Net Energy Metering program work?

The NEM program uses a bi-directional meter to track the "net" difference between the amount of electricity you produce and the amount of electricity you consume during each billing period. This can be accomplished on a cumulative basis or on a time-of-use basis, depending upon your rate schedule.

As a Residential/Small Commercial NEM customer, you will continue to receive monthly bills, but only for non-energy related charges such as taxes and fees. On an annual basis, you will be billed for electricity based on your net use for the previous year – for example, the amount of electricity you used minus the amount you generated. Large Commercial/Industrial NEM Customers will continue to receive monthly bills, which will require payment of the monthly non-energy related charges (taxes and standard billing fees) and “Net” energy charges.

What are the NEM program eligibility requirements?

To be eligible for NEM, your system must be sized to your historic electric use up to 1,000 kilowatts, located on your premises and interconnected to operate in parallel with our electrical system. We offer several NEM programs:

Standard Solar and Renewables NEM Fuel Cell NEM Virtual Net Metering (VNM)

For 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 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 ‘Benefitting 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.

3Qualifying “solid waste conversion” is defined pursuant to Public Resources Code Section 25741(b)(3).

Do you pay me money for excess energy I produce?

In accordance with Assembly Bill 920, signed into law on October 11, 2009, customers on the NEM Rate Schedule are eligible to receive compensation for net surplus electricity in 2011. For more information, see the AB290 FAQs below.

Are there any Incentive Programs available to Customers interconnecting a renewable generator under the Net Energy Metering program?

For more information, visit our California Solar Initiative site.

NSHP is available to customers installing eligible solar photovoltaic (PV) systems on new residential buildings. The NSHP program provides two incentive structures, one for conventional or market rate housing and another for qualified affordable housing projects.

Additional information is available online on the NSHP website.

What other incentives are available to me to increase my net generation capacity?

You can take advantage of any of our many energy efficiency program options.

Do customers need to take any action?

No. Existing NEM customers will automatically be placed on the new successor tariff after the conclusion of their transition period.

How is the NEM Program Limit Calculated?

The NEM program limit is based on 5 percent of SCE’s aggregated customer peak demand, which is currently set at 2,240 MW. This amount is reviewed annually on October 1, but can never decrease below 2,240 MW in accordance with Public Utilities Code Section 2827(c)(4)(B)(ii).

Where can I find more information on the transition rules?

For full details on the transition rules, please review the NEM tariff

Where can I find the latest numbers of customers in SCE’s service territory taking service under NEM and the combined capacity of their generating systems?

The Net Energy Metering Cap Data and participation numbers are updated monthly by the 10th day of each month for the previous month.

NEM Program Transition

What is the transition period?

If you are a customer already participating in a NEM program at the time the NEM limit is reached or before July 1, 2017, whichever occurs first, you will be allowed to continue participating in that NEM program in accordance with CPUC Decision 14-03-041. This means that you will continue to be eligible under your current NEM program for a period of 20 years from your original interconnection approval date (i.e., Permission to Operate Letter (PTO) date) and ending at the conclusion of your annual Relevant Period that ends immediately on or after the 20th anniversary of your original PTO date.
For example, if April 1, 2014 is your original NEM interconnection date, you would be eligible to stay on your current NEM program through the conclusion of the Relevant Period ending immediately on or after March 31, 2034.

After to the 20th anniversary of your original PTO date you will be automatically transitioned to the NEM successor tariff.

Who does the transition period apply to?

The transition period applies to customers who take service on Schedules  Net Energy Metering (NEM) (NEM), Virtual Net Energy Metering for Multi-Tenant and Multi-Meter Properties (NEM-V), Multifamily Affordable Solar Housing Virtual Net Metering (MASH-VNM), or NEM Aggregation before July 1, 2017, or when the SCE’s reaches its NEM program limit of 5 percent of SCE’s aggregated customer peak demand (currently set at 2,240MW and reviewed annually each October 1).

When does eligibility for the transition period end?

Eligibility for the transition period will end either July 1, 2017, or the date SCE reaches its NEM program limit, whichever occurs sooner.

What would disqualify a customer’s generating facility from being eligible to retain its 20-year transition period?

If the Renewable Electrical Generating Facility is modified or repaired after July 1, 2017 or the date SCE reaches its NEM limit (whichever is sooner), the customer can remain eligible for their entire transition period only if the generator capacity is not modified by more than the greater of (1) 10 percent of the renewable generator’s nameplate rating capacity, as established when the renewable generator was originally issued PTO, or (2) 1 kW; and provided the modifications and/or repairs do not result in the renewable generator exceeding a total generation capacity of 1 MW and the customer’s annual onsite load.

If the capacity increase is greater than 1 kW or 10% of the originally approved generator capacity, the customer has the following options:

  • Meter the added capacity separately under the successor tariff (meaning the non-modified portion of the system would retain its NEM transition period eligibility), or
  • Elect for the whole system to take service under the successor tariff.

What if a customer transfers ownership of the renewable generator?

If the renewable generator is transferred to a new owner, operator, or SCE account at the original location, it will not lose eligibility for the original 20-year transition period unless the customer elected to transition to the successor program sooner.

The transfer of an existing Renewable Electrical Generating Facility to a new location is considered a new installation requiring a new interconnection agreement and would not qualify for the 20-year transition period if the relocation occurs on or after the date SCE reaches its NEM trigger level or July 1, 2017, whichever is earlier.

Will customers have the option to transition to the successor program sooner?

Yes. The successor program will be developed in a stakeholder process under the direction of the CPUC during 2014 and 2015. Once the successor tariff is developed, customers will have the option to move to the successor program prior to the expiration of their 20-year transition period. If the customer elects an early transition, they cannot later move back to the previously applicable Schedules Net Energy Metering (NEM), Virtual Net Energy Metering for Multi-Tenant and Multi-Meter Properties (NEM-V), Multifamily Affordable Solar Housing Virtual Net Metering (MASH-VNM), or NEM Aggregation.

NEM Aggregation

What are the eligibility requirements for Net Energy Metering (NEM) Aggregation?

In order to qualify, your renewable generating facility must be sized to not exceed the annual on-site load of all the aggregated accounts. In addition, the renewable electrical generating facility, or a combination of those facilities, must have a total generating capacity of not more than one megawatt (MW).

All accounts must be located on the same property as the renewable electrical generating facility; or must be located on property that is adjacent or contiguous to the property on which the renewable electrical generating facility is located, and those properties must be all solely owned, leased or rented by the same customer. Properties that are divided by a street, highway, or public thoroughfare are considered contiguous, provided they are within an unbroken chain of otherwise contiguous parcels and are all solely owned, leased or rented by the same customer.

All accounts in an NEM Aggregation arrangement must be (1) all Bundled Service accounts; or (2) all Direct Access (DA) Service accounts served by the same Energy Service Provider (ESP); or (3) all Community Choice Aggregation (CCA) service accounts served by the same CCA. You can have more than one NEM aggregation arrangement, but accounts may not be shared across multiple arrangements.

You must have an NEM-eligible generator to participate in NEM aggregation; however, you can also have a non-NEM–eligible generator behind the same meter of the aggregated accounts.

How do I apply for NEM Aggregation?

If you are not making modifications to existing generating facilities, complete and submit by email to customer.generation@sce.com the NEM Aggregation Form 14-937, listing the account directly interconnected to and located on the same property as the Renewable Electrical Generating Facility (REGF) and all additional metered service accounts to be aggregated.

If you are installing a new generating facility or are making modifications to existing generating facilities, please submit the standard Rule 21 interconnection application package (i.e., Form 14-732 or 14-753) by email to customer.generation@sce.com and include the NEM Aggregation Form 14-937, listing the account directly interconnected to and located on the same property as the REGF and all additional metered service accounts to be aggregated.

How does NEM Aggregation apply to Direct Access (DA) and Community Choice Aggregation (CCA) customers?

DA and CCA customers are eligible to participate in NEM Aggregation if your ESP or CCA agrees to support the NEM Aggregation provisions of Schedule NEM. The ESP or CCA must provide their agreement to support these provisions before your associated accounts can/will be placed on NEM Aggregation. You will receive only any applicable delivery credits from us, and must to look to your ESP or CCA for any corresponding generations credits.

If your ESP or CCA declines to support NEM Aggregation, you have several options:

  • You may choose to remain with your alternate service provider, forego being served on our Schedule NEM, and benefit from the reduced usage resulting from the operation of their system.
  • You may choose to switch to a different ESP that does support the NEM Aggregation provisions of our NEM tariff.
  • You may choose to return to our bundled service in order to qualify for NEM Aggregation.

Note: SCE cannot speak for the ESP or CCA and cannot discuss the ESP’s or CCA’s reason(s) for declining to support NEM or NEM Aggregation. This is an issue to be addressed between the customer and their ESP or CCA only. 

Can I add or remove accounts included in the NEM Aggregation arrangement?

You can change the accounts included in an NEM Aggregation arrangement (either add or remove) provided the removal of any account(s) does not result in the REGF being oversized compared to the load of the remaining accounts.

Notification must be provided to us at least 60-days prior to the change taking effect, and such change remains in effect for a minimum of 12 months.

What are the NEM Aggregation Billing Services Charges?

There is a one-time $25 per account set-up fee, capped at $500.00 per NEM Aggregation arrangement. Any account added to an NEM Aggregation arrangement is subject to this one-time fee. There is also a $5 monthly billing fee per account.

These interim billing fees may be adjusted in late 2015 on a going-forward basis.

How will the bill credit be calculated for the NEM Aggregated arrangement?

The electrical consumption of kilowatt-hours (kWh) registered on each aggregated account’s meter will be reduced, for NEM billing purposes, by a proportional allocation, at the 15-minute interval level, of the electricity generated by the REGF that is exported to our grid. The proportional allocation is determined per billing period based on the cumulative consumption of each aggregated account compared to the cumulative consumption of your NEM Aggregation arrangement since the start of the relevant period, and the cumulative generation exported from the REGF since the start of the relevant period.

You are required to designate one account in the NEM Aggregation arrangement to receive any remaining kWh not allocated due to rounding, after the proportional allocation methodology described above is completed.

NEM AGGREGATION EXAMPLE (kWh)
  Billing Account 1 Billing Account 2 Generation Account 1 Allocated Generation to Billing Account 1 Allocated Generation to Billing Account 2
January 100 400 400 80 320
February 150 500 500 116 384
March 300S 600 800 260 540

How are the terms “Adjacent and Contiguous” applied for the purposes of participating in NEM Aggregation?

For the purposes of NEM Aggregation only, parcels that are divided by a street, highway, or public thoroughfare are considered contiguous, provided they are within an unbroken chain of otherwise contiguous parcels and are all solely owned, leased or rented by the Customer, as verified in Form 14-937. You are also eligible to participate in NEM Aggregation where all meters in an NEM Aggregation arrangement are located within an unbroken chain of contiguous parcels that are all solely owned, leased, or rented by you.

NEM Application

How do I apply for Net Energy Metering (NEM)?

Refer to NEM Documents and Forms for required documents by NEM program type, to download forms and other resources.

1. Submit the initial Application Packet. This will consist of the application, Single Line Diagram and Plot Plan. Please submit as early as possible, before the system is installed and the final inspection by the local building and safety department is scheduled.

To expedite processing, we recommend you submit a signed NEM Interconnection Agreement with the Initial Application Packet.

Notes:
We no longer require an original signature on The Interconnection Agreement for Renewable Technologies (Form 16-344) or The Agreement for Solar & Wind up to 10 kW (Form 14-923) so the signed Agreement may be faxed or mailed to us. For all other NEM programs, the original customer signature must be mailed to SCE NEM Program, P.O. Box 800, Rosemead, CA 91770. If we have not received a signed Agreement by the time we review the Application Packet, we will mail one to the customer to sign and return to us.

The individual signing the Interconnection Agreement must be duly authorized to bind the Customer of Record to its terms.

Residential customers: if the individual is not the person listed on the electric bill, they must be listed as a spouse on the service account. To add a spouse to an account, please call our Customer Service at 866-701-7868. Non-residential customers: unless the individual is an owner of a proprietorship, officer of a corporation, "director” or general manager of an agency, or an equivalent official. Please submit documentation showing the signature authority of the individual who does sign on behalf of the "Customer of Record."

2. Submit a copy of the Final Electrical Inspection and Approval from the local jurisdictional authority, typically the Building & Safety department, as soon as it is issued.

Application documents may be submitted via email to customer.generation@sce.com or by fax to 626-571-4272. As of March 31, 2011, we will no longer accept documents via mail.

NEM Email Subject Lines for Documentation Submittals

To ensure we can easily identify the nature of your submission and route it accordingly, we ask that you adopt the following subject lines for all future submissions:

  • New Application: NEW, site address
  • Paired Storage Device: Battery-(New/Correction/Final), site address
  • Signed Interconnection Agreement: IA, site address
  • Final Inspection (New & Revised): FINAL, site address
  • Inquiry about the Status of a Pending Project: STATUS, site address

  • Aggregation: Aggregation-(New/Correction), site address


Once your application packet has been reviewed and accepted, and the final electrical inspection of the system by the local building & safety department has been verified, you will receive a Permission to Operate (PTO) letter with an NEM tag for you to place on your meter to notify our field personnel about the presence of your generating system and as proof of your permission to operate.

Is there a size limit for email attachments?

Yes. We can accept email attachments up to 7 MB. However, if the total size of attached files exceeds 7 MB, please submit them in multiple emails adding the following to the subject lines: 'part 1 of 2,' 'part 2 of 2,' etc. Emails that are larger than 7 MB will be rejected by our email servers due to sizing limitations.

How long does the NEM application process take?

The NEM review process can take 2-5 weeks depending on the complexity of the system and how early in the process the paperwork is submitted.  

We strongly recommend that you submit the application, Single Line Diagram, Plot Plan, and signed Interconnection Agreement as early as possible, at least 30 days prior to scheduling an inspection by the local jurisdictional authority.   This allows ample time for us to evaluate program eligibility, conduct a technical review of the proposed system and initiate a meter change, if necessary.   With this approach, We will be ready to issue a Permission to Operate (PTO) letter quickly upon receipt of the final electrical approval issued by the local jurisdictional authority.

Within 30 days of the date we receive your complete application, you will be enrolled in the NEM program, which will include a meter change if one is required and transition to the appropriate NEM rate schedule.

What happens once I’m enrolled in the NEM program?

Once you are enrolled in the NEM program, you’ll continue to receive monthly bills listing non-energy related charges, such as taxes and fees. On an annual basis, your bill will also include ‘net’ electricity charges – i.e. charges for the amount of energy you used minus the energy you produced.

If you have additional questions about your meter or bill, please contact our Net Metering Customer Call Centers:

Residential Customers: 1-866-701-7868

Commercial Customers: 1-866-701-7869

What type of metering is required and do I have to pay for it?

All customers participating in Net Energy Metering (NEM) must have a bi-directional meter, one that measures electricity flow in two directions. If your current meter is not bi-directional, we will replace it with a bi-directional meter as part of enrolling you in an NEM program.

Note: We charge Direct Access customers for meter replacement. 

I’m moving into a house with a self-generation system already installed. What do I need to do to benefit from the NEM program?

If there have been no modifications to the original installed system, and the system size is less than 30 kW, you don’t need to do anything. You will be automatically enrolled in the NEM program, and you will receive additional information via mail.

If your system is > 30 kW, or modifications are made to the original installed system, you will need to sign a new NEM Interconnection Agreement (Form 16-344). If the system is over 3 years old, it must be inspected (Form 14-903) before you can enroll in the NEM Program. We will mail an Agreement and Inspection Form soon after you move in, or you can download the forms and email to customer.generation@sce.com

What if I add more solar panels?

If you add solar panels after you receive your Permission to Operate, you must submit a revised Interconnection Application for your new system, including all additional equipment, to our Generation Interconnection Services. We will perform an engineering analysis to ensure our facilities can accommodate the increased generation capabilities of the new system. You must still meet all the requirements of the NEM program to continue on the NEM rate, including the size limitations. If you received a CSI or SGIP incentive for your solar or wind installation, you must also satisfy the requirements of those programs.

I moved into a house that has a solar system. How do I enroll in the program?

Most customers who move into homes with previously interconnected solar PV systems are automatically enrolled in our NEM program. If your PV system is larger than 30 kW, you must submit an Interconnection Agreement Form and if the solar system is over three years old, it must be inspected before you are enrolled in the NEM program.

NEM Interconnection with a Paired Energy Storage Device (e.g., batteries)

What is an NEM-paired storage system?

An NEM paired storage system is a term used to describe an NEM eligible generator that has an integrated or directly connected energy storage device (e.g., a battery) behind the same revenue meter.

How do I apply for interconnection if I have an energy storage device?

If the storage device is paired with a Net Energy Metering (NEM) eligible generator (e.g., solar, wind, etc.), an interconnection application package (including but not limited to the Application Form 14-732, Interconnection Agreement Form 16-344 and Single Line Diagram) that includes the energy storage and NEM generator information must be submitted to customer.generation@sce.com. An Interconnection Addendum that describes the energy storage device will also need to be completed and submitted. This Addendum will be in place until SCE files an Advice Letter with the California Public Utilities Commission (Commission or CPUC) to update its tariffs and forms to accommodate NEM-paired storage devices. For metering requirements, see the FAQs below regarding this topic.

If the energy storage device is stand alone or not paired with an NEM generator, then the interconnection application must be submitted to Rule21@sce.com and is subject to the appropriate fees. For questions regarding the Rule 21 application process, send an email to interconnectionQA@sce.com or call 626-302-3688.

Are there sizing requirements for an energy storage device paired with an NEM eligible generator?

If the energy storage device has an Inverter Rating of 10 kW (AC) and below, there are no sizing restrictions or requirements for the storage device (e.g., no requirement to be sized to the customer demand or the NEM generator).

For energy storage devices where the Inverter Rating is >10 kW (AC), the maximum output power of the storage device cannot be larger than 150% of the NEM Renewable Electrical Generating Facility’s (REGF) capacity. For example, if the REGF is sized to load at 20 kW, then the inverter rating for the storage device can be a maximum of 30 kW (AC).

Note that rebate programs such as the Self-Generation Incentive Program (SGIP) may have a different sizing requirement for the energy storage device. As such, you’ll need to ensure that the size of the storage device meets both the NEM tariff and rebate program requirements in order to qualify and take advantage of both programs.

Is an energy storage device considered a generator when paired with an NEM-eligible generator?

No. When paired with an NEM-eligible generator, the storage device is considered an addition or enhancement to that NEM-eligible generating facility and is not a separate “generator” as defined under the Rule 21 interconnection tariff, provided the applicable sizing and metering requirements are adhered to.

What (if any) are the metering requirements for an NEM-paired energy storage system?

For NEM-paired storage facilities where the storage device has an Inverter Rating of 10 kW (AC) and below, no additional metering on either the NEM REGF or the storage device is required. Instead, an estimation methodology will be used in lieu of metering to validate the eligible NEM credits. However, a customer can opt-in to installing a net generation output meter (NGOM) or non-export relay, when it is technically feasible to do so, instead of having the estimation methodology applied. In this case, the project must adhere to the metering requirements similar to those in the NEM-MT (multiple tariff) section of Schedule NEM. Metering costs are capped at $600, subject to the exceptions described below.

For NEM-paired storage facilities where the storage device has an Inverter Rating >10 kW (AC), the project must adhere to the metering requirements similar to those in the NEM-MT section of Schedule NEM. These projects will be required to 1) install a non-export relay on the storage device(s) or 2) install a NGOM directly to the NEM REGF(s). Projects falling under this category must adhere to the NEM-MT metering provisions, and are not eligible for the estimation methodology in lieu of metering.

Metering costs for NEM-paired storage projects are capped at $600. However, the $600 cap does not apply to systems requiring more complex metering solutions. For these purposes, “more complex metering” is defined as those systems requiring more than two self-contained meters or any non-self-contained meters (CTs/PTs).

Why is a net generation output meter (NGOM) or non-export relay required for an NEM-Paired energy storage systems where the storage device is > 10 kW?

An NGOM or non-export relay is required for NEM-paired storage systems where the storage device is sized >10 kW (AC) to ensure that NEM credits are only earned for energy generated and exported to the grid by the REGF.

What is the process for ordering a net generation output meter?

The applicant needs to contact the local service planning office to order the meter. Service Planning Office locations and phone number can be found in the General Information section of the Electrical Service Requirements (ESR) document found at

https://www.sce.com/nrc/aboutsce/regulatory/distributionmanuals/esr.pdf.

If my NEM generator (i.e. photovoltaic, wind, etc.) has been issued the Permission to Operate (PTO) letter and I’m simply adding the energy storage device, what is the interconnection submittal process?

Although the PTO letter has been issued for the NEM generator, the addition of an energy storage device requires the customer to submit an interconnection application package. An interconnection application package (including but not limited to the Application Form 14-732, Interconnection Agreement Form 16-344 and Single Line Diagram) that includes the energy storage and existing NEM generator information must be submitted to Customer.Generation@sce.com. An Interconnection Addendum that describes the energy storage device will also need to completed and submitted. This Addendum will be in place until SCE files an Advice Letter with the CPUC to update its tariffs and forms to accommodate NEM-paired storage devices (this filing will likely occur in Fall/Winter 2014). For metering requirements, see the FAQs below regarding this topic.

If the energy storage device is stand alone or not paired with an NEM generator, then the interconnection application must be submitted to Rule21@sce.com and is subject to the appropriate fees. For questions regarding the Rule 21 application process, send an email to interconnectionQA@sce.com or call 626-302-3688.

Why is an estimation methodology being used for NEM-Paired energy storage systems where the storage device is ≤ 10 kW (AC)?

The CPUC, in the NEM-paired Storage Decision (D.14-05-033), explained that the use of an estimation methodology based on a presumed generation profile of the REGF balances the Commission’s priority of ensuring NEM integrity with a cost-effective solution.

Note that a customer with an NEM-paired storage device sized at or below 10 kW (AC) can opt-in to install an NGOM net generator output meter when it is technically feasible to do so instead of having the estimation methodology applied. Metering costs are capped at $600.

When will the estimation methodology for NEM-Paired energy storage systems where the storage device is ≤ 10 kW be applied and reflected on a customer’s account?

The CPUC is currently working with the Investor Owned Utilities (IOUs) and other stakeholders on developing the estimation methodology. The CPUC will issue a separate ruling on this matter. Until the estimation methodology is approved by the CPUC, NEM-paired energy storage systems where the storage device is ≤ 10 kW are permitted to interconnect under the existing NEM tariff without being subject to any metering or sizing requirements.

Will customers who previously paid applicable Rule 21 fees and charges get a refund as a result the NEM-Paired Storage Decision (D. 14-05-033), which places a $600 metering cost cap on NEM-Paired energy storage systems?

SCE has begun the process of refunding previously paid interconnection charges for a) metering and b) application fees and distribution upgrades, etc.
The refund for the metering portion is subject to the $600 cap, meaning if a customer had installed an NGOM as required and previously paid $800, for example, then SCE would refund $200 (difference between $600 cap and the amount paid), assuming the customer did not require a more complex metering solution (see question Metering Requirements).
Application fees, distribution upgrades, etc. are refunded at 100% of what was originally paid.

Can I remain on the current NEM tariff if I increase the size of my energy storage device paired with the NEM generator when the new NEM successor tariff is in place (after SCE’s 5% NEM cap is reached or on July 1, 2017 (whichever is earlier)?

The energy storage device’s inverter capacity can be increased by 10% and still remain on the current NEM tariff and be eligible for the 20-year transition period. Also, the 10% increase in the storage device’s inverter is independent from the 10% or 1 kW increase allowed for the NEM REGF.

For NEM-paired energy storage systems that share an inverter sized at 10 kW (AC) and below, an increase to the storage or generator are applied as a combined percentage for the purposes of the expansion calculation.

NEM-paired energy storage systems that share an inverter rated at >10 kW (AC) that are unable to adhere to the NEM-MT metering requirements are not eligible for NEM. As such, the expansion calculation that triggers a shift to the NEM successor tariff does not apply.

The energy storage device’s inverter capacity can be increased by 10% and still remain on the current NEM tariff and be eligible for the 20-year transition period. Also, the 10% increase in the storage device’s inverter is independent from the 10% or 1 kW increase allowed for the NEM REGF.

NEM-paired energy storage systems that share an inverter rated at >10 kW (AC) that are unable to adhere to the NEM-MT metering requirements are not eligible for NEM. As such, the expansion calculation that triggers a shift to the NEM successor tariff does not apply.

Does the size of the energy storage device paired with an NEM generator count towards the NEM 1 MW per Premises limit and 5% Participation Cap?

No, the size of the storage device does not count towards the 5% NEM cap or the 1 MW per premises limit. Only the size of the NEM REGF counts towards these limits.

Net Surplus Energy Compensation

What is net surplus generation or energy?

Net surplus generation (or energy) occurs when, over the course of your Relevant Period, your Renewable Electrical Generating Facility (solar or wind generator) exports more kWh to the grid than you receive from us.

Is there a minimum amount you will compensate me for?

No, there is no minimum payment. We will compensate you for any Net Surplus Compensation credit (dollar amount). Please refer to your tax advisor or the IRS for any rules related to the Net Surplus Compensation.

Am I eligible to receive NSC if I am a Direct Access (DA) Customer?

DA Customers are not eligible to receive Net Surplus Compensation from SCE.

Am I eligible to receive NSC if I am a Community Choice Aggregation (CCA) Customer?

CCA customers are not eligible to receive Net Surplus Compensation from SCE.

Am I eligible to receive NSC if I participate on BG-NEM or FC-NEM?

Customers participating on BG-NEM and FC-NEM are not eligible to receive Net Surplus Compensation from SCE.

Can I enroll in NSC if I am a MASH / NSHP low income customer?

In order to receive Net Surplus Compensation (NSC) for any Net Surplus Energy, you need to complete and submit the Net Surplus Compensation Rate and Renewable Energy Credits Compensation Selection Form (14-906) prior to SCE processing the final bill of your Relevant Period.

Each customer of record of either a tenant unit account or a common area account who receives credit under our NEM Virtual Net Metering (VNM) tariffs is eligible for NSC, provided the customer has Net Surplus Energy. If the electricity (in kWh) allocated to the customer’s account exceeds the customer’s usage during the Relevant Period, the customer is eligible to receive NSC.

Will I get compensated for the net surplus energy if my panels are owned by a third party?

If you are an NEM customer, you are eligible to receive Net Surplus Compensation from SCE for any net surplus electricity you generate.

Can I install a larger-than-necessary or oversized Renewable Electrical Generating Facility to become a net generator?

The NEM program is designed for customers who want to install renewable generation to offset their own onsite load. To be a participant in the NEM program and to be eligible to receive Net Surplus Compensation, you are required to install a system that is sized, at most, to offset your annual onsite consumption only.

How can I tell if I have generated surplus electricity?

On your annual Relevant Period true-up statement, if the Total Energy Amount (kWh) is negative, you have generated surplus electricity and are eligible for Net Surplus Compensation. If the Total Energy amount is positive, you used more electricity than you produced over the course of your Relevant Period, and therefore are not eligible to receive Net Surplus Compensation.

Sometimes I have monetary credit at the time of my Relevant Period. Does this mean I get Net Surplus Compensation credit?

Not necessarily. Payment is issued only if the customer has net surplus electricity (i.e., the customer exports more kilowatt-hours (kWh) to the grid than the customer uses over the Relevant Period). It is rare for a customer to have a monetary credit remaining at the end of a full 12-month Relevant Period and not have net surplus electricity. This can happen, however, with customers that export to the grid during peak periods when electricity is more expensive, and use energy from the grid during off-peak periods when electricity costs less.

If I download the Net Surplus Compensation Rate and Renewable Energy Credits Compensation Selection Form, how do I return it to you?

The completed Net Surplus Compensation Rate and Renewable Energy Credits Compensation Selection Form (14-906) can be emailed to us (preferred channel) or mailed to the address on the form.

What will happen if I don’t send the Net Surplus Compensation Rate and Renewable Energy Credits Compensation Selection Form to you?

In order to receive Net Surplus Compensation for any Net Surplus Energy, you need to complete and submit the Net Surplus Compensation Rate and Renewable Energy Credits Compensation Selection Form (14-906) prior to SCE processing the final bill of your Relevant Period. However, as a courtesy for customers with Net Surplus Energy who have not submitted the form by the end of their Relevant Period, SCE will send a selection form that must be completed and returned to us within 90 days from the date of the letter to receive compensation. Customers will not receive payment if the completed form is not received within the 90-day grace period.

How will I get compensated for the surplus electricity I generate?

Before or at the end of your Relevant Period, if you have generated more kWh than used, we will send you a selection form that must be completed and returned to us within 90 days from the date of the letter to receive compensation. Customer will not receive payment if the completed form is not received within the 90-day grace period. Your compensation selection will be noted on your electric bill and kept in your billing records until you decide to change your selection. The selection form describes your compensation options. There are two ways an NEM customer can receive NSC:

1. The customer may receive a check through the mail for the value (dollar amount) of the net surplus energy, excluding any amount owed to us for other charges on their electric bill. At the end of each Relevant Period, the customer’s account will be zeroed out, and the new Relevant Period will begin on the next regularly scheduled meter read date.

2. The customer may roll the credit over to the next Relevant Period. We will reconcile the customer’s account and apply the NSC earned (dollar amount) toward the customer’s next Relevant Period. At this point, the account will be zeroed out and the new Relevant Period will begin on the next regularly scheduled meter read date. Any NSC credit can be applied to energy or non-energy charges. We will maintain a customer’s NSC credit indefinitely, until it is fully used, or until the account is closed. If your account is closed, we will return any unused credit in your account in the form of a check to the mailing address identified on your account.

If I change my mind about the type of compensation that I want to receive (i.e., check versus bill credit), can I change my selection?


Yes. You can submit a new Net Surplus Compensation Rate and Renewable Energy Credits Compensation Selection Form (14-906) once every 12 months to cancel participation in the program or to change the method of compensation. The completed form can be emailed to us (preferred channel) or mailed to the address on the form.

How is the dollar amount of my net surplus compensation credit calculated?

Net Surplus Compensation (NSC) is equal to the Net Surplus Compensation Rate (NSCR) multiplied by your Net Surplus Energy. The NSCR is based on the default load aggregation point (DLAP) price. We use a simple rolling average of day ahead DLAP electricity prices from 7:00 a.m. to 5:00 p.m. corresponding to each customer’s 12-month Relevant Period. The rolling average is calculated on a monthly basis to be effective the first of each month and is applied to eligible Net Surplus Generators with Relevant Periods ending in that month. The monthly NSCR rates can be found here.

What is AB 920?

Assembly Bill (AB) 920 (Huffman, 2009) made modifications to the law that governs the implementation of the NEM program applicable to customers served on Schedules NEM, MASH-VNM and NEM-V. Before AB 920, customers received no compensation at the end of their Relevant Periods for Net Surplus Energy. As a result of AB 920, eligible Net Surplus Generators are now eligible to receive NSC at the end of their Relevant Periods.

Who is affected by AB 920?

AB 920 applies to our Net Energy Metering (NEM) customers who take service on Schedules NEM, MASH-VNM and NEM-V.

How long will the changes enacted by AB 920 remain in effect?

The Legislature can make changes to any existing law at any time, and any such changes must be signed into law by the governor.

If you are a customer already participating in a NEM program at the time the NEM limit is reached or before July 1, 2017, whichever occurs first, you will be allowed to continue participating in that NEM program in accordance with CPUC Decision 14-03-041. This means that you will continue to be eligible under your current NEM program for a period of 20 years from your original interconnection approval date (i.e., Permission to Operate Letter (PTO) date) and ending at the conclusion of your annual Relevant Period that ends immediately on or after the 20th anniversary of your original PTO date.

After to the 20th anniversary of your original PTO date you will be automatically transitioned to the NEM successor tariff.

Renewable Energy Compensation

What is a REC?

REC stands for Renewable Energy Credit (also known as a WREGIS Certificate) and represents the renewable attributes of your solar or wind energy generation. Each REC represents one megawatt-hour (MWh) or 1,000 kilowatt-hour (kWh) of renewable generation and it is tracked and recorded by the Western Renewable Energy Generation Information System.

The REC portion of the excess generation compensation provides additional credit for energy generated by a renewable energy source. This extra compensation is called a Renewable Attribute Adder, and its rate is set annually. As of October 1, 2013, the rate was 1.6 cents per surplus kWh (https://www.sce.com/wps/portal/home/regulatory/tariff-books/rates-pricing-choices/renewable-energy-credit).

The California Energy Commission (CEC) established NEM customer eligibility and certification process through the CEC Renewables Portfolio Standard (RPS) Guidebook, sections II Energy Resource Eligibility Requirements, III Facility Requirements, IV Certification, available at: www.energy.ca.gov/renewables/documents/#rps.

To create RPS eligible RECs, the generator must be certified with the CEC, registered with WREGIS, and report renewable generation to WREGIS.

You must have a generating system ≤ 360 kW in size to self-report; otherwise WREGIS requires a Qualified Reporting Entity (QRE)/Aggregator to report on your behalf.

You must obtain ownership certification of RECs before requesting compensation for any RECs.

What do I need to do to request REC payment for my AB 920 Net Surplus Generation (NSG)?

 

If you are interested in seeking Renewable Energy Credit (REC) compensation for any renewable attributes of your generation, as specified in the steps below, you must certify that you own the RECs associated with your generating facility and your net surplus generators must be certified as Renewable Portfolio Standard (RPS) eligible by the California Energy Commission (CEC). Your net surplus generator must also meet CEC-approved REC tracking requirements for your generation to be counted for RPS purpose.

The REC portion of the excess generation compensation provides additional credit for energy generated by a renewable energy source. This extra compensation is called a Renewable Attribute Adder, and its rate is set annually. As of October 1, 2013, the rate was 1.6 cents per surplus kWh.

The CEC’s process has several steps to complete, and may be financially beneficial if you produce more than 12,000 surplus kWh over a 12-month period – but may not provide a worthwhile benefit otherwise.

To meet the RPS Guidebook requirements indicated above, you must submit documentation before we can evaluate compensation for REC attributes. These are the steps to request payment for RECs from Net Surplus Generation (NSG):

  • Register your generating unit(s) in the Western Renewable Energy Generation Information System (WREGIS) to create RECs for your Net Surplus Generation (NSG). Each registered generating unit will receive a WREGIS Generating Unit Identification (GUID) Number. For more information, visit www.wecc.biz/WREGIS/Pages/GeneratingUnitRegistrationProcess.aspx.

    WREGIS will ask you to become an “Account Holder.” The Account Holder annual fee is based on the size of your generator. As of January 2014, the minimum fee was $200. Please reference WREGIS Fee Matrix and Definitions for more information.
  • Complete a CEC application for Renewable Portfolio Standard certification, available at www.energy.ca.gov/renewables/documents/index.html#rps. Have your WREGIS GUID on hand to complete your application.
  • Report your NSG in WREGIS for the related GUID (your NSG appears on your NEM bill statement at the end of your annual Relevant Period 12-month billing cycle). You must report to WREGIS the NSC kWh within 75 days (WREGIS Operating Rules page 37)
  • Complete the enclosed Net Surplus Compensation Rate and Renewable Energy Credits Compensation Selection Form 14-935, attach a copy of the CEC RPS eligibility certificate and submit it to SCE.
  • In WREGIS, transfer ownership of your RECs to SCE.

What is a WREGIS Qualified Reporting Entity (QRE)?

A Qualified Reporting Entity (QRE) in WREGIS is an organization providing renewable generation data for the purpose of creating WREGIS Certificates that has met the Qualified Reporting Entity Guidelines established in the QRE-ICD located on the WREGIS website www.wregis.org and WREGIS Operating Rules Section 10.1.

What are the requirements to be a WREGIS Qualified Reporting Entity (QRE)?

For more information visit the WREGIS Qualified Reporting Entity (QRE) Registration Process page.

How do I find a WREGIS Qualified Reporting Entity (QRE)?

Go to the WREGIS web page and view WREGIS Active Account Holders public report at

Using the drop down list on the page, filter for Non-Balancing Authority Reporting Entity. You will notice that SCE is registered as a QRE in WREGIS. SCE, however, only acts as a QRE for its own RECs that it accumulates as a result of its power procurement activities. SCE does not perform QRE services for its customers.

When can I expect to receive REC payment after I have submitted the required paperwork?

If there are no issues with the submitted paperwork, you should receive compensation within 90 days after validation of your submittal.

If you have not received a notification regarding your submittal or compensation within 90 days, please us an email (email subject line “Status of REC compensation for Service Account 3-xxx-xxxx-xx).

You can also call 866-701-7868 (Residential NEM Customers) or 866-701-7869 (Business NEM Customers).

How do I calculate the value for my Renewable Energy Credit (REC)?

The value of a REC = Net surplus kWhs x RAA (Renewable Attribute Adder)
You can find the Renewable Attribute Adder rate at
(https://www.sce.com/wps/portal/home/regulatory/tariff-books/rates-pricing-choices/renewable-energy-credit).

A REC represents one megawatt-hour (MWh) or 1,000 kilowatt-hour (kWh) of renewable generation and it is tracked and recorded by the Western Renewable Energy Generation Information System

How is the value of the Renewable Attribute Adder (RAA) established?

The RAA is established using the most recent Western Electricity Coordinating Council (WECC) average renewable premium, based on United States Department of Energy (DOE) published data in accordance with Decision 11-06-016 Ordering Paragraph 2.

Where do I find the value for the Renewable Attribute Adder?

You can find the Renewable Attribute Adder value at
(sce.com/wps/portal/home/regulatory/tariff-books/rates-pricing-choices/renewable-energy-credit).

What is WREGIS?

The Western Renewable Energy Generation Information System (WREGIS) is an independent, renewable energy tracking system for the region covered by the Western Electricity Coordinating Council (WECC). WREGIS tracks renewable energy generation from units that register in the system by using verifiable data and creating renewable energy certificates (REC) for this generation.

What are the WREGIS fees?

When did AB 920 REC compensation process take effect?

On January 25, 2014, the Energy Division of the Public Utilities Commission approved the changes to the schedule NEM tariff (Advice letter 2975-E) for Renewable Energy Credit Compensation for Eligible Net Energy Metering Customers.

Residential Time-of-Use (TOU-D), NEM Billing and Other Rate Options

How is the Baseline Credit included in TOU-D, Option A applied to a customer’s bill?

TOU-D, Option A includes a Baseline Credit, which is applicable to up to 100 percent of a customer’s standard Baseline Allocation, as found in Preliminary Statement, Part H. (Click here for further information: https://www.sce.com/NR/sc3/tm2/pdf/ce07-12.pdf) This results in a lower energy charge for Baseline usage.

Net Consumer of Electricity

When you are a net consumer for the month (i.e., you consume more electricity from SCE than you export to the grid), a portion of your energy charges will be lowered through the baseline credit applied monthly on a $per kWh basis. For example:

  • If a customer has a Baseline Allocation of 500 kWh/month and their net kWh (consumption from SCE minus exported generation) for the month is 750 kWh, the customer will receive 10 cents per kWh credit up to the 500 kWh Baseline amount, equal to a $50 credit.
  • If a customer has a Baseline Allocation of 500 kWh/month and their net kWh for the month is 250 kWh, the customer will receive 10 cents per kWh credit up to the net 250 kWh, equal to a $25 credit.

 

Net Generator of Electricity

When you are a net generator for the month (i.e., you export more electricity than you consume from SCE that month), the Baseline Credit will appear as a monthly charge since you are multiplying a negative kWh amount by a negative billing factor.  This is necessary to ensure that you receive the same rate for the exported kWh that you would have received if you had consumed that same kWh from SCE.

For example, if a customer has a Baseline Allocation of 500 kWh/month, and their net kWh for the month is -100 kWh (exported generation is greater than consumption from SCE), the customer’s bill will reflect a 10 cents per kWh charge up to the net -100 kWh of generation, which results in a $10 charge.

Note: The Baseline Allocation varies by Baseline Region. You can learn your specific region and allocation by calling us at 1-800-655-4555 and asking an SCE representative.

How does the TOU-D rate On-Peak hours impact my bill?

If you generate excess electricity (i.e., export more electricity than you consume from SCE) during the hours of 2 PM to 8 PM, your NEM credits will be calculated using the TOU-D on-peak rate for the applicable season, meaning that the kWh exported between these hours will receive the highest credit amount.

If you do not generate enough electricity to offset your on-site load during the hours of 2 PM to 8 PM, it is important to try to shift as much of your electric load (e.g., PEV charging, clothes and dish washing or pool pump operation) as you can to Off-Peak and Super Off-Peak hours to reduce your electric costs since kWh consumed in the On-Peak hours are charged at a higher rate than kWh consumed in the Off-Peak and Super Off-Peak hours

What is the Basic Charge on both Options A and B of Schedule TOU-D and why are they different?

The Basic Charge is a mechanism approved by the California Public Utilities

Commission’s (CPUC) that allows SCE to recover some of the costs associated with ensuring the grid can provide safe and reliable power to all customers. This charge ensures that all SCE residential customers, regardless of their monthly use, contribute toward the recovery of these costs.

  • Customers choosing Option A are generally lower usage customers who will pay a basic charge corresponding to the customer charge in place for customers taking service on Schedule D.
  • Customers choosing Option B are generally higher usage customers who will pay a higher basic charge but lower energy charges (cents/kWh).

I received my Permission to Operate (PTO) letter, but it took a while before I started receiving kWh credits. Why?

Within 30 days of the date SCE receives all required paperwork, you will be enrolled in the NEM program, which will include a meter change if one is required and you’ll begin to the billed on the NEM Rate Tariff.

I installed a solar system, why is my bill so high?

The weather conditions play a key role in solar generation system kWh production. If weather conditions are cloudy or rainy, the system will not generate as much as it would during clear and sunny conditions. You should also be conscious of the energy that you are using such as air conditioning, pool filters, etc. 

Can I request a change to my Relevant Period start date?

You may elect to change the start date of your Relevant Period on a one-time prospective basis by completing and returning to SCE Form 14-936, NEM One-Time Relevant Period Change Request Form (i.e., aligning the Relevant Period to your business fiscal budget year; production cycles such as crop-growing season; other business needs; or personal convenience).

You will be responsible to select the date of the requested change. SCE must receive this form at least 60 days prior to the requested start date of the new Relevant Period. When the start date is changed, your existing Relevant Period will end and your new 12-month Relevant Period will begin. In no case will a Relevant Period extend beyond 12 months.

Please understand that your Relevant Period can only be changed one time.
